A number divided by 10 is 6. Yoongi got the result by subtracting 15 from a certain number. What is the result he got?
|
Let's call the certain number "x". According to the information given:
A number divided by 10 is 6:
x / 10 = 6
Yoongi got the result by subtracting 15 from x:
Result = x - 15
First, we need to find the value of x. We can do this by solving the first equation:
x / 10 = 6
x = 6 * 10
x = 60
Now that we know x is 60, we can find the result Yoongi got by subtracting 15 from x:
Result = x - 15
Result = 60 - 15
Result = 45
So, the result Yoongi got is 45.

You wanted to subtract 46 from a number, but you accidentally subtract 59 and get 43. How much do you get from the correct calculation?
|
If you accidentally subtracted 59 instead of 46 and got 43, you can find the original number by adding 59 back to 43:
43 + 59 = 102
Now, to find the result of the correct calculation, subtract 46 from the original number:
102 - 46 = 56
So, if you subtract 46 from the original number, you would get 56.

In this case, the quotient is 6, the divisor is 9, and the remainder is 5. Plugging these values into the formula, we get:
A = (6 × 9) + 5
A = 54 + 5
A = 59
Therefore, the value of A is 59.
|
How many diagonals can you draw in a decagon?
|
A decagon is a polygon with 10 sides. To find the number of diagonals in a polygon, you can use the formula:
Number of diagonals = n(n - 3) / 2
where n is the number of sides in the polygon.
For a decagon, n = 10, so:
Number of diagonals = 10(10 - 3) / 2
Number of diagonals = 10(7) / 2
Number of diagonals = 70 / 2
Number of diagonals = 35
Therefore, you can draw 35 diagonals in a decagon.

Find the sum of all multiples of 9 that are less than 80.
|
To find the sum of all multiples of 9 that are less than 80, we first need to identify these multiples. We start with 9 and keep adding 9 until we reach a number that is just below 80.
The multiples of 9 less than 80 are:
9, 18, 27, 36, 45, 54, 63, 72.
Now, we add these numbers together to find the sum:
9 + 18 + 27 + 36 + 45 + 54 + 63 + 72 = 324
Therefore, the sum of all multiples of 9 that are less than 80 is 324.

The exchange rate refers to the rate at which one country's currency is exchanged for another country's currency. Soojeong came back from a trip to the U.S. and exchanged the remaining 140 dollars for 158,760 won in Korean money at the bank today. What is the exchange rate of the Korean Won to the US Dollar today?
|
To find the exchange rate of the Korean Won to the US Dollar, we need to divide the amount of Korean Won Soojeong received by the amount of US Dollars she exchanged.
So, the exchange rate (KRW/USD) is:
158,760 KRW / 140 USD = 1,134 KRW/USD
Therefore, the exchange rate is 1,134 Korean Won to 1 US Dollar.

A parallelogram was cut to form a trapezoid, the lower side being 4 centimeters (cm) longer than the upper side. If the upper side is 12 centimeters (cm) and the height is 10 centimeters (cm), how much is the area of this trapezoid?
|
The area of a trapezoid can be calculated using the formula:
Area = (1/2) * (sum of the lengths of the parallel sides) * height
In this case, the upper side of the trapezoid is 12 cm and the lower side is 4 cm longer than the upper side, so the lower side is 12 cm + 4 cm = 16 cm.
The height of the trapezoid is given as 10 cm.
Now we can plug these values into the formula:
Area = (1/2) * (12 cm + 16 cm) * 10 cm
Area = (1/2) * 28 cm * 10 cm
Area = 14 cm * 10 cm
Area = 140 cm²
So, the area of the trapezoid is 140 square centimeters.

Volume = Width × Length × Height
Given the dimensions of the gift box Yuran wants to buy:
Width = 9 cm
Length = 4 cm
Height = 7 cm
Volume = 9 cm × 4 cm × 7 cm
Volume = 36 cm² × 7 cm
Volume = 252 cm³
So, the volume of the gift box is 252 cubic centimeters (cm³).

Farm A has a rectangular shape measuring 6 kilometers (km) by 9 kilometers (km), and Farm B has a square shape measuring 8 kilometers (km) by 8 km by 8 kilometers (km). The owners of both farms want to build a fence around the perimeter of the farm by putting together wooden planks of the same length. Which farm needs more planks?
|
To determine which farm needs more planks, we need to calculate the perimeter of each farm.
For Farm A (rectangular shape):
Perimeter = 2 * (length + width)
Perimeter = 2 * (6 km + 9 km)
Perimeter = 2 * 15 km
Perimeter = 30 km
For Farm B (square shape):
Perimeter = 4 * side
Perimeter = 4 * 8 km
Perimeter = 32 km
Farm B has a perimeter of 32 km, while Farm A has a perimeter of 30 km. Therefore, Farm B needs more planks to build a fence around its perimeter.

Seungyeon is wrapping the box with ribbon tape. If 28 identical boxes are wrapped with the ribbon tape that is 82.04 meters (m) long and there should be no tape left after wrapping, how many meters (m) of ribbon tape are needed to wrap one box?
|
To find out how many meters of ribbon tape are needed to wrap one box, we can divide the total length of the ribbon tape by the number of boxes.
Total length of ribbon tape = 82.04 meters
Number of boxes = 28
Ribbon tape needed for one box = Total length of ribbon tape / Number of boxes
Ribbon tape needed for one box = 82.04 meters / 28 boxes
Now, let's do the calculation:
Ribbon tape needed for one box = 2.93 meters
So, 2.93 meters of ribbon tape are needed to wrap one box.
|
The four students, Jimin, Yoongi, Taehyung, and Namjoon, are of different ages. Yoongi is older than Namjoon, and Jimin is older than Taehyung but younger than Namjoon. Who is the youngest among the 4 people?
|
Given the information:
1. Yoongi is older than Namjoon.
2. Jimin is older than Taehyung.
3. Jimin is younger than Namjoon.
From point 3, we know Namjoon is older than Jimin. Since Jimin is older than Taehyung, Taehyung is younger than both Jimin and Namjoon. We also know from point 1 that Yoongi is older than Namjoon.
So, the age order from oldest to youngest is: Yoongi, Namjoon, Jimin, Taehyung.
Therefore, Taehyung is the youngest among the four.
|
Taehyung is trying to get to his grandmother's house, which is 300 kilometers (km) away on a motorcycle at 60 kilometers (km) per hour. Find how far Taehyung needs to go when 2 hours have passed since he left.
|
If Taehyung is traveling at a speed of 60 kilometers per hour, then in 2 hours he would have traveled:
60 km/hour * 2 hours = 120 kilometers
Since his grandmother's house is 300 kilometers away, and he has already traveled 120 kilometers, the remaining distance he needs to travel is:
300 kilometers - 120 kilometers = 180 kilometers
So, Taehyung still needs to go 180 kilometers to reach his grandmother's house.
|
Find A that satisfies 32×A×A×A=42592
|
To find the value of A that satisfies the equation 32×A×A×A=42592, we can rewrite the equation as:
\(32A^3 = 42592\)
Now, we need to isolate A by dividing both sides of the equation by 32:
\(A^3 = \frac{42592}{32}\)
\(A^3 = 1331\)
Now, we take the cube root of both sides to solve for A:
\(A = \sqrt[3]{1331}\)
\(A = 11\)
Therefore, the value of A that satisfies the equation is 11.
|
When a number is multiplied by 14, it is 458.64. When a number is divided by 17, round the remainder to two decimal places.
|
First, let's find the number that when multiplied by 14 gives 458.64.
To do this, we divide 458.64 by 14:
458.64 / 14 = 32.76
So the number is 32.76.
Now, when this number is divided by 17, we want to find the remainder and round it to two decimal places.
32.76 / 17 = 1 with a remainder of 15.76
To round the remainder to two decimal places, we don't need to do anything further since it is already in that format.
Therefore, the remainder when 32.76 is divided by 17, rounded to two decimal places, is 15.76.
|
Taehyung has 45 candies. If he plans to give 5 candies to his friends, how many friends can get candies in maximum?
|
If Taehyung has 45 candies and he plans to give 5 candies to each friend, we can find out how many friends can get candies by dividing the total number of candies by the number of candies each friend will receive.
45 candies ÷ 5 candies per friend = 9 friends
So, a maximum of 9 friends can get candies.
|
There are two types of Korean language workbooks and four types of math workbooks. When choosing one book among them, in how many cases can you choose Korean workbook or math workbook?
|
If there are two types of Korean language workbooks and four types of math workbooks, then the total number of cases where you can choose either a Korean workbook or a math workbook is the sum of the two types of workbooks.
Number of Korean workbooks = 2
Number of Math workbooks = 4
Total number of cases to choose either a Korean workbook or a math workbook = Number of Korean workbooks + Number of Math workbooks
Total = 2 + 4 = 6 cases
So, there are 6 different cases where you can choose either a Korean workbook or a math workbook.

A car that requires 0.14 liters (l) of gasoline to run 1 kilometer (km) ran for 2 hours and 30 minutes at 93.6 kilometers (km) per hour. How many liters of gasoline did it use?
|
First, we need to calculate the total distance the car traveled. The car ran for 2 hours and 30 minutes at a speed of 93.6 km/h.
2 hours and 30 minutes is equal to 2.5 hours (since 30 minutes is half an hour).
Distance = Speed × Time
Distance = 93.6 km/h × 2.5 h
Distance = 234 km
Now that we know the distance, we can calculate the amount of gasoline used. The car requires 0.14 liters of gasoline to run 1 km.
Gasoline used = Distance × Gasoline per km
Gasoline used = 234 km × 0.14 l/km
Gasoline used = 32.76 liters
The car used 32.76 liters of gasoline.

|
The smallest two-digit number that can be formed by two of 0, 3, 4, 6, and 8 is subtracted by a certain number and it became 7. Find the number.
|
The smallest two-digit number that can be formed by two of the given numbers (0, 3, 4, 6, and 8) is 30, because 0 cannot be the first digit of a two-digit number.
If this number (30) is subtracted by a certain number and it became 7, we can set up the following equation to find the certain number:
30 - x = 7
Now, we solve for x:
x = 30 - 7
x = 23
So, the certain number is 23.
|
A regular hexagon with an area of 21.12 square centimeters (cm2) is divided into six pieces. If the cut pieces have the same shape and size, find the area of one piece in square centimeters (cm2).
|
If a regular hexagon with an area of 21.12 cm² is divided into six equal pieces, each piece will have the same shape and size because the hexagon is regular (all sides and angles are equal).
To find the area of one piece, we simply divide the total area of the hexagon by the number of pieces:
Area of one piece = Total area of hexagon / Number of pieces
Area of one piece = 21.12 cm² / 6
Area of one piece = 3.52 cm²
So, the area of one piece is 3.52 square centimeters.
|
I should have subtracted 23, but I mistakenly subtracted 32 from some number and got 25. How much do you get when calculated correctly?
|
If you mistakenly subtracted 32 instead of 23 from a number and got 25, we can first find the original number before the mistake by adding 32 back to 25:
25 + 32 = 57
Now, to find the correct result, we subtract the intended number, which is 23, from the original number:
57 - 23 = 34
So, when calculated correctly, you get 34.

|
The rectangular shape of the ttakji's area is 1.77 square centimeters (cm2). If the width of this ttakji is 3 centimeters (cm), how many centimeters (cm) will the length be?
|
To find the length of the ttakji, we can use the formula for the area of a rectangle:
Area = Length × Width
We know the area (1.77 cm²) and the width (3 cm), so we can rearrange the formula to solve for the length:
Length = Area ÷ Width
Plugging in the values we have:
Length = 1.77 cm² ÷ 3 cm
Length = 0.59 cm
So, the length of the ttakji will be 0.59 centimeters.
|

|
It is said that it takes an hour to make 8 toys from one machine. How many hours would it take to make 200 toys using 5 machines?
|
If one machine takes an hour to make 8 toys, then in one hour, 5 machines would make 5 times as many toys.
So, 5 machines would make 5 * 8 = 40 toys in one hour.
To make 200 toys, we would divide the total number of toys needed by the number of toys produced per hour by 5 machines.
200 toys / 40 toys per hour = 5 hours
Therefore, it would take 5 hours to make 200 toys using 5 machines.
|
It rained 135 millimeters (mm) yesterday and 12 centimeters (cm) 7 millimeters (mm) today. Find the answer on which day it rained more between yesterday and today.
|
To compare the rainfall between yesterday and today, we need to convert the measurements to the same unit. Since the measurements are given in millimeters and centimeters, we'll convert the centimeters to millimeters because 1 centimeter is equal to 10 millimeters.
Yesterday's rainfall: 135 mm
Today's rainfall: 12 cm 7 mm
First, convert the centimeters to millimeters:
12 cm = 12 * 10 mm = 120 mm
Now, add the 7 mm to the converted centimeters:
120 mm + 7 mm = 127 mm
Now we can compare:
Yesterday: 135 mm
Today: 127 mm
It rained more yesterday with 135 mm compared to today's 127 mm.

Multiplying a number by 11 and adding 1 equals 45. Find the number.
|
Let's call the number we are looking for "x". According to the problem, if we multiply x by 11 and then add 1, we get 45. We can write this as an equation:
11x + 1 = 45
Now, we need to solve for x. First, we'll subtract 1 from both sides of the equation to isolate the term with x:
11x + 1 - 1 = 45 - 1
11x = 44
Next, we'll divide both sides of the equation by 11 to solve for x:
11x / 11 = 44 / 11
x = 4
So, the number we are looking for is 4.
|

There is a number that is a multiple of 9. The quotient of a number divided by 9 is then divided again by 9, and the quotient is 25 and the remainder is 7. Find the number.
|
Let's denote the number we are looking for as N.
According to the problem, when N is divided by 9, we get a quotient which we'll call Q. Then, when Q is divided by 9, the quotient is 25 and the remainder is 7.
So, we can write the second division as:
Q = 9 * 25 + 7
Now, let's calculate Q:
Q = 9 * 25 + 7
Q = 225 + 7
Q = 232
Now, we know that N divided by 9 equals Q. So we can write:
N = 9 * Q
Substitute the value of Q we found into the equation:
N = 9 * 232
N = 2088
Therefore, the number we are looking for is 2088.

A is a number comprised of 1 group of 1000, 16 groups of 100, and 28 groups of 10. B is calculated as 3 jumps from 355 with an interval of 245. Find the value of A-B.
|
First, let's calculate the value of A:
A = (1 group of 1000) + (16 groups of 100) + (28 groups of 10)
A = (1 * 1000) + (16 * 100) + (28 * 10)
A = 1000 + 1600 + 280
A = 2600 + 280
A = 2880
Now, let's calculate the value of B:
B is calculated as 3 jumps from 355 with an interval of 245. This means we add 245 to 355 three times.
First jump: 355 + 245 = 600
Second jump: 600 + 245 = 845
Third jump: 845 + 245 = 1090
So, B = 1090
Now, we can find the value of A - B:
A - B = 2880 - 1090
A - B = 1790
Therefore, the value of A - B is 1790.

JungKook and Jimin walked up the stairs to the third floor. Jimin took the elevator from the 3rd floor to the 5th floor. Who has risen higher, Jung Kook or Jimin?
|
Jimin has risen higher because he took the elevator from the 3rd floor to the 5th floor, which means he has gone up two floors. JungKook only walked up the stairs to the third floor, starting from an unspecified floor. Without knowing the starting floor for JungKook, we can only confirm that Jimin has risen to a higher floor, the 5th floor.
|
A is 348 and A is less than B by 173. C is greater than B by 299. Find C.
|
If A is 348 and A is less than B by 173, we can find B by adding 173 to A:
B = A + 173
B = 348 + 173
B = 521
Now, if C is greater than B by 299, we can find C by adding 299 to B:
C = B + 299
C = 521 + 299
C = 820
Therefore, C is 820.
|
A is 3 groups of 10 and 7 individual units, and B is the number obtained by subtracting 1 from 40. Which is smaller, A or B?
|
Let's calculate the value of A and B.
A is 3 groups of 10 and 7 individual units. So, A = (3 * 10) + 7 = 30 + 7 = 37.
B is the number obtained by subtracting 1 from 40. So, B = 40 - 1 = 39.
Now, we compare A and B.
A = 37
B = 39
Since 37 is less than 39, A is smaller than B.
|
There are 9 dogs and 23 cats. How many more cats are there than dogs?

23 cats - 9 dogs = 14 more cats than dogs.
|
You have a rectangle with a perimeter of 40 centimeters (cm). If the width of this rectangle is 8 centimeters (cm), how many centimeters (cm) is the length?
|
The perimeter of a rectangle is given by the formula:
Perimeter = 2 * (length + width)
Given that the perimeter is 40 cm and the width is 8 cm, we can plug these values into the formula to find the length:
40 = 2 * (length + 8)
First, divide both sides by 2 to isolate the length:
40 / 2 = (length + 8)
20 = length + 8
Now, subtract 8 from both sides to solve for the length:
20 - 8 = length
12 = length
Therefore, the length of the rectangle is 12 centimeters.

To find the multiples of 4 that are less than 30, we can start by dividing 30 by 4.
30 ÷ 4 = 7.5
Since we are looking for whole multiples, we take the integer part of the result, which is 7. This means that the largest multiple of 4 that is less than 30 is 4 times 7, which is 28.
Now, we list the multiples of 4 up to 28:
4, 8, 12, 16, 20, 24, 28
Counting these, we find that there are 7 multiples of 4 that are less than 30.

Yewon ran at a speed of 180 meters (m) in 30 seconds. How many meters (m) did Yewon run in 1 minute?
|
If Yewon ran 180 meters in 30 seconds, then in 1 minute (which is 60 seconds), she would run twice that distance because 60 seconds is twice as long as 30 seconds.
So, in 1 minute, Yewon would run:
180 meters * 2 = 360 meters
Yewon ran 360 meters in 1 minute.

10's are 21, 1's are 8, 0.1's are 5, and 0.01's are 34 in a certain number. How much is this number?
|
To find the number, we need to add the values of each place:
- The 10's place has 21 tens, which is 21 * 10 = 210.
- The 1's place has 8 ones, which is 8 * 1 = 8.
- The 0.1's place has 5 tenths, which is 5 * 0.1 = 0.5.
- The 0.01's place has 34 hundredths, which is 34 * 0.01 = 0.34.
Now, we add all these values together:
210 (from the 10's) + 8 (from the 1's) + 0.5 (from the 0.1's) + 0.34 (from the 0.01's) = 218.84
So, the number is 218.84.

There are 45 apples. There are 21 fewer pears than apples. How many tangerines are there if there are 18 fewer pears than tangerines?
|
Let's break it down step by step:
1. We know there are 45 apples.
2. There are 21 fewer pears than apples, so we subtract 21 from the number of apples to find the number of pears:
Number of pears = Number of apples - 21
Number of pears = 45 - 21
Number of pears = 24
3. There are 18 fewer pears than tangerines, so we add 18 to the number of pears to find the number of tangerines:
Number of tangerines = Number of pears + 18
Number of tangerines = 24 + 18
Number of tangerines = 42
So, there are 42 tangerines.

Yoongi has 4, and Jungkook has a number that is the quotient of 6 divided by 3. Who has the bigger number?
|
Jungkook has a number that is the quotient of 6 divided by 3, which is 2 (since 6 ÷ 3 = 2). Yoongi has 4. Therefore, Yoongi has the bigger number.
|
There is a number that is divisible by 5 and the resulting quotient is 4. Subtract 10 from that particular number, and then multiply by 3, and then subtract 18. What is the answer?
|
Let's call the number we're looking for "N".
According to the problem, N is divisible by 5 and the resulting quotient is 4. So we can write this as:
N / 5 = 4
To find N, we multiply both sides by 5:
N = 4 * 5
N = 20
Now, we subtract 10 from N:
20 - 10 = 10
Next, we multiply this result by 3:
10 * 3 = 30
Finally, we subtract 18 from this result:
30 - 18 = 12
So the answer is 12.
|
You want to create a three-digit number by selecting three out of 5, 6, 4, and 7 and using them only once. Find the sum of the digits of the largest possible number.

7 + 6 + 5 = 18
So, the sum of the digits of the largest possible number is 18.
|
63 is the result of mistakely adding 44 and subtracting 39 when you actually have to add 39 to this certain number and subtract 44. Find the result of the correct calculation.
|
Let's call the certain number "x".
According to the mistake, the calculation was:
x + 44 - 39 = 63
Now, let's correct the calculation as per the instructions:
x + 39 - 44
First, let's find the value of x from the mistaken calculation:
x + 44 - 39 = 63
x + 5 = 63
x = 63 - 5
x = 58
Now that we have the value of x, we can perform the correct calculation:
58 + 39 - 44
Let's do the math:
58 + 39 = 97
97 - 44 = 53
So, the result of the correct calculation is 53.
|
Find the smallest number that can be made by using all the number cards 0, 2, 4, 6, 8 and 9 only once.

If dividing a particular number by 10 gives you 6, then the particular number is 6 * 10 = 60.
If you subtract 15 from that particular number (60), you get:
60 - 15 = 45
So, when you subtract 15 from that particular number, you get 45.
|
Jungkook, who had 6 apples, received 3 more. When Yoongi has 4 apples, who has fewer apples?
|
Yoongi has fewer apples. He has 4 apples, while Jungkook has a total of 6 + 3 = 9 apples.
|
Yoongi's aunt is 38 years old. Yoongi is 23 years younger than his aunt. Hoseok is 4 years younger than Yoongi. What is the sum of Yoongi and Hoseok's ages?
|
If Yoongi's aunt is 38 years old and Yoongi is 23 years younger than his aunt, then Yoongi is:
38 - 23 = 15 years old.
If Hoseok is 4 years younger than Yoongi, then Hoseok is:
15 - 4 = 11 years old.
The sum of Yoongi and Hoseok's ages is:
15 (Yoongi's age) + 11 (Hoseok's age) = 26 years.
|
You have a square with a perimeter of 17.8 centimeters (cm). How many centimeters (cm) is one side of this figure?
|
To find the length of one side of the square, we need to divide the total perimeter by the number of sides a square has, which is 4.

It takes 4 days to process 240 kilograms (kg) of rice with the (A) machine. How many days does it take to process 1920 killograms (kg) of the same rice with the (A) machine?
|
To find out how many days it takes to process 1920 kg of rice with the (A) machine, we can set up a proportion based on the information given:
4 days : 240 kg = X days : 1920 kg
We can solve for X (the number of days to process 1920 kg) by cross-multiplying:
4 days * 1920 kg = X days * 240 kg
7680 kg*days = 240 kg * X days
Now, we divide both sides by 240 kg to solve for X:
7680 kg*days / 240 kg = X days
X = 32 days
So, it takes 32 days to process 1920 kg of rice with the (A) machine.

Given the information:
1. Taehyung's house is lower than Namjoon's.
2. Jimin's house is higher than Yoongi's.
3. Yoongi's house is higher than Namjoon's.
From point 3, we know Yoongi lives higher than Namjoon, and from point 1, Taehyung lives lower than Namjoon. Therefore, Taehyung must live on the lowest floor because he is lower than Namjoon, who is lower than Yoongi, and Jimin is higher than Yoongi.
|
The number of pencils is 6 times the number of notebooks. I distributed the notebooks to 6 people, and each person had 9 of them, and there was nothing left. Find the number of pencils.
|
If each of the 6 people received 9 notebooks, then the total number of notebooks distributed is:
6 people * 9 notebooks/person = 54 notebooks
Since the number of pencils is 6 times the number of notebooks, the number of pencils is:
6 times 54 notebooks = 324 pencils
So, there are 324 pencils.
|
Subtracting 477 from a number equals 273. How much is a number plus 273?
|
Let's call the unknown number "x". According to the given information:
x - 477 = 273
To find the value of x, we add 477 to both sides of the equation:
x - 477 + 477 = 273 + 477
x = 750
Now, we want to find the value of x + 273:
750 + 273 = 1023
So, the number plus 273 is 1023.
|

There is an octadecagon-shaped pattern. If you try to draw as many diagonal lines as you can on this pattern, how many can you draw?
|
An octadecagon is a polygon with 18 sides. To find the number of diagonals in any polygon, you can use the formula:
Number of diagonals = n(n - 3) / 2
where n is the number of sides in the polygon.
For an octadecagon, n = 18. Plugging this into the formula gives:
Number of diagonals = 18(18 - 3) / 2
Number of diagonals = 18(15) / 2
Number of diagonals = 270 / 2
Number of diagonals = 135
So, you can draw 135 diagonals in an octadecagon-shaped pattern.

A 1000 milliliter (ml) bottle was full of milk, but the bottle cracked and milk leaked at a rate of 5 ml (ml) per minute. After a few minutes, if you look at the milk bottle and there are 300 milliliters (ml) of milk left, find how many minutes have passed.
|
If the bottle started with 1000 ml of milk and there are 300 ml left, then the amount of milk that has leaked out is:
1000 ml - 300 ml = 700 ml
Since the milk is leaking at a rate of 5 ml per minute, we can find out how many minutes have passed by dividing the total amount of milk that has leaked by the rate of leakage:
700 ml / 5 ml per minute = 140 minutes
So, 140 minutes have passed since the bottle started leaking.
|
58 flags were planted at equal intervals on both sides of the 191.8 meters (m) long road. If flags are planted at both the beginning and end of the road, find the distance between the flags in meters (m).
|
If flags are planted at both the beginning and end of the road, then there are 58 flags in total, with 29 flags on each side of the road. Since there is a flag at the beginning and end of the road, there are 28 intervals between the 29 flags on each side.
To find the distance between the flags, we need to divide the total length of the road by the number of intervals.
The total length of the road is 191.8 meters, and there are 28 intervals, so the distance between the flags is:
191.8 meters / 28 intervals = 6.85 meters
Therefore, the distance between the flags is 6.85 meters.
|
Ayeon tries to go to a hospital 0.09 kilometers (km) away. If Ayeon takes 4 seconds to go 3 meters (m), how many seconds does it take for her to get to the hospital?
|
First, we need to convert the distance to the hospital from kilometers to meters, since Ayeon's speed is given in meters per second.
1 kilometer = 1000 meters
So, 0.09 kilometers = 0.09 * 1000 meters = 90 meters
Now, we know that Ayeon takes 4 seconds to go 3 meters. To find out how many seconds it takes her to go 1 meter, we divide the time by the distance:
4 seconds / 3 meters = 1.3333 seconds per meter
Now, we can find out how many seconds it takes for her to go 90 meters:
90 meters * 1.3333 seconds per meter = 120 seconds
Therefore, it takes Ayeon 120 seconds to get to the hospital.
|
You will need a 1/4 meter (m) block of wood. How many blocks can you make with 3 meters (m) of wood?
|
To determine how many 1/4 meter blocks can be made from 3 meters of wood, you divide the total length of wood by the size of each block:
3 meters ÷ 1/4 meter = 3 meters ÷ 0.25 meters = 12 blocks
So, you can make 12 blocks of 1/4 meter each from 3 meters of wood.
|

|
In the bookstore, all but 4 of the 40 books were sold out. There were 4 customers in total, and they all bought the same number of books. How many books did a customer buy?
|
If all but 4 of the 40 books were sold out, then 40 - 4 = 36 books were sold.
Since there were 4 customers and they all bought the same number of books, we can divide the total number of books sold by the number of customers to find out how many books each customer bought.
So, 36 books sold ÷ 4 customers = 9 books per customer.
|
There are 44 students in A class. B class has 2 more studemts than A class, and C class has 1 less stuendt than B class. How many students are in C class?
|
If A class has 44 students, then B class, which has 2 more students than A class, would have:
44 (A class) + 2 = 46 students.
Now, C class has 1 less student than B class, so:
46 (B class) - 1 = 45 students.
Therefore, C class has 45 students.
|
52 is the result of mistakenly subtracting 48 from a certain number while 48 had to be added. Find the result of the correct calculation.
|
Let's call the certain number "x".
According to the mistake, the calculation was:
x - 48 = 52
To find the value of x, we add 48 to both sides of the equation:
x - 48 + 48 = 52 + 48
x = 100
Now, we need to find the result of the correct calculation, which is adding 48 to x:
x + 48 = 100 + 48
x + 48 = 148
So, the result of the correct calculation is 148.
|
I needed to divide a number by 3 and then subtract 5. However, I mistakenly multiplied this number by 3 and subtracted 5 and got 103 as a result. Find the correct calculated value.
|
Let's denote the original number as \( x \).
According to your mistake, you multiplied the number by 3 and then subtracted 5:
\[ 3x - 5 = 103 \]
Now, let's solve for \( x \):
\[ 3x = 103 + 5 \]
\[ 3x = 108 \]
\[ x = \frac{108}{3} \]
\[ x = 36 \]
Now that we have the original number, we can calculate the correct value by dividing it by 3 and then subtracting 5:
\[ \frac{x}{3} - 5 \]
\[ \frac{36}{3} - 5 \]
\[ 12 - 5 \]
\[ 7 \]
So the correct calculated value is 7.

Solving for x:
20 = x * 5
x = 20 / 5
x = 4
Now, we need to find the product of 7 and the sum of the number (x) and 5:
7 * (x + 5) = 7 * (4 + 5)
7 * 9 = 63
Therefore, the product of 7 and the sum of the number and 5 is 63.
|
What is B when 1/4×1/8=1/(4×A)=1/B?
|
To find the value of B, we can start by simplifying the given equation:
1/4 × 1/8 = 1/(4×A) = 1/B
First, let's simplify the leftmost part of the equation:
1/4 × 1/8 = 1/32
Now we have:
1/32 = 1/(4×A) = 1/B
Since 1/32 is equal to 1/(4×A), we can set them equal to each other:
1/32 = 1/(4×A)
Now, we can solve for A:
32 = 4×A
A = 32/4
A = 8
Now that we have the value of A, we can find B by using the equation:
1/32 = 1/B
Cross-multiplying gives us:
B = 32
So, the value of B is 32.

To find the area of one of the divided parts of the regular hexagon, we simply divide the total area of the hexagon by the number of parts it is divided into.
The total area of the hexagon is 21.12 cm², and it is divided into 6 equal parts.
So, the area of one divided part is:
21.12 cm² / 6 = 3.52 cm²
Each divided part of the hexagon has an area of 3.52 cm².
|
Of the two digits that can be created by taking two different numbers out of 1, 0, 5, and 8, what is the largest minus the second largest?
|
To find the two largest two-digit numbers that can be created from the digits 1, 0, 5, and 8, we need to arrange the digits in descending order, making sure to use the largest digits in the tens place.
The largest two-digit number we can create is 85 (using the digits 8 and 5).
The second largest two-digit number we can create is 81 (using the digits 8 and 1, since 0 cannot be used in the tens place as it would not make a two-digit number).
Now, we subtract the second largest from the largest:
85 - 81 = 4
So, the largest two-digit number minus the second largest two-digit number is 4.
|
Multiply a number by 5 to get 100. What is the value of the number when divided by 10?

5 * x = 100
To find the value of x, divide both sides of the equation by 5:
x = 100 / 5
x = 20
Now, you want to know the value of x when it is divided by 10:
x / 10 = 20 / 10
x / 10 = 2
So, the value of the number when divided by 10 is 2.
|
Namjoon has 3 sets of 7 marbles. He is going to make these marbles into 6 groups of 6 each. How many more marbles does he need?
|
Namjoon has 3 sets of 7 marbles, so he has a total of 3 * 7 = 21 marbles.
He wants to make 6 groups of 6 marbles each, which means he needs a total of 6 * 6 = 36 marbles.
To find out how many more marbles he needs, we subtract the number of marbles he has from the number he needs:
36 (needed) - 21 (has) = 15 marbles.
Namjoon needs 15 more marbles to make 6 groups of 6.

|
A number needs to be divided by 5, but when it was accidentally divided by 8, the quotient was 156 and the remainder 2. Find the value that comes out when the calculation is done correctly.
|
When the number was divided by 8, the quotient was 156 and the remainder was 2. To find the original number, we can use the formula:
Original number = (Divisor * Quotient) + Remainder
In this case, the divisor is 8, the quotient is 156, and the remainder is 2. So we have:
Original number = (8 * 156) + 2
Original number = 1248 + 2
Original number = 1250
Now that we have the original number, we can divide it correctly by 5:
Correct quotient = Original number / 5
Correct quotient = 1250 / 5
Correct quotient = 250
So, when the calculation is done correctly, the value that comes out is 250.
|
A figure has a perimeter of 49 centimeters (cm) and a side length of 7 centimeters (cm). How many sides are there in total?
|
To find the number of sides in the figure, we can divide the total perimeter by the length of one side.
Perimeter = Number of sides × Length of one side
Given that the perimeter is 49 cm and the length of one side is 7 cm, we can set up the equation:
49 cm = Number of sides × 7 cm
Now, we divide both sides of the equation by 7 cm to solve for the number of sides:
Number of sides = 49 cm / 7 cm
Number of sides = 7
Therefore, the figure has 7 sides in total.

Each of the two beakers contains a liquid. The sum of the solutions contained in the two beakers is 9.28 milliliters (ml). If one beaker contains 2.95 milliliters (ml), what is the difference in milliliters (ml) between the two beakers?
|
Let's call the amount of liquid in the first beaker A and the amount in the second beaker B. We know that A + B = 9.28 ml and that one of the beakers (let's say A) contains 2.95 ml.
To find the amount in the second beaker (B), we can subtract the amount in the first beaker (A) from the total amount:
B = 9.28 ml - 2.95 ml
B = 6.33 ml
Now, to find the difference between the two beakers, we subtract the smaller amount (A) from the larger amount (B):
Difference = B - A
Difference = 6.33 ml - 2.95 ml
Difference = 3.38 ml
So, the difference in milliliters between the two beakers is 3.38 ml.
|
What is the total length in centimeters (cm) of 30 wooden sticks 25 centimeters (cm) long when 6 centimeters (cm) are overlapped?
|
If 6 centimeters are overlapped for each consecutive stick, then each stick effectively adds only (25 - 6) centimeters to the total length.
So, the effective length added by each stick is:
25 cm - 6 cm = 19 cm
Since there are 30 sticks, the total effective length added by 29 sticks is:
29 sticks * 19 cm/stick = 551 cm
The first stick will contribute its full length since there is no overlap at the beginning, so we add the full 25 cm of the first stick to the total length:
551 cm + 25 cm = 576 cm
Therefore, the total length of the 30 wooden sticks with 6 cm overlap is 576 cm.
