Question: If the terms of a series are either2or24and the sum of all the terms S of the series is 124, then which of the following could be the number of2sin the series?
A: 26
B: 29
C: 35
D: 40
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Ans: A
Solution: we are not certain how many 2 or 24 are there. but as given sum of all the terms is 124 means 24*5= 120 so number of 24 can't be more than 5
so S=24x +2y = 124
24*5 + 2y =124 then y=2
24*4 + 2y = 124 then y=14
24*3 +2y = 124 then y= 26
24*2 +2y =124 then y = 38
24 +2y = 124 then y= 50
26 is the ans.

Question: What term means the adjusting of systems within a cell in order to restore balance or maintain equilibrium?
A: systemic regulation
B: gaseous regulation
C: aftertouch regulation
D: homeostatic regulation
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Homeostasis refers to the balance, or equilibrium, within the cell or a body. It is an organism’s ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is referred to as homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the normal proportions of all internal substances. This involves continual adjustments in transport of substances across the cell membrane. Homeostasis is a dynamic equilibrium rather than an unchanging state. The cellular processes discussed in the cell transport (passive and active transport) concepts all play an important role in homeostatic regulation.

Answer the following multiple choice question by selecting the correct option.
Context: Water has remarkable properties. Water expands when it freezes, even though all other substances contract. This means that in the winter ice on a pond or lake will float. Water has high surface tension because polar molecules tend to stick together. That's why drops stick together or some bugs can walk on the surface of a pond. Without water, life might not be able to exist on Earth. If it did exist, it would not be as diverse or as complex.

Question: Two stores sell the same model of smartphone, but they offer it at different prices and with different discounts. Store A lists the smartphone at a full price of $125 and offers an additional discount of 8%. Store B lists the same smartphone for $130 and offers an additional discount of 10%. After both stores' discounts are applied, how much cheaper is store A's smartphone than store B's smartphone?
A: 3
B: -8
C: 1
D: 2
Answer:

Answer the following multiple choice question by selecting the correct option.
Context: Store A has a $125 x 8/100 = $<<125*8/100=10>>10 discount.
So the smartphone from store A will only cost $125 - $10 = $<<125-10=115>>115.
Store B has a $130 x 10/100 = $<<130*10/100=13>>13 discount.
So the smartphone from store B will only cost $130 - $13 = $<<130-13=117>>117.
Thus, store A's smartphone is $117 - $115 = $<<117-115=2>>2 cheaper than that of store B.

Answer the following multiple choice question by selecting the correct option.
Context: This question can be solved by TESTing VALUES, but there's a particular pattern that you have to recognize to make the workeasy.
We're not really limited by anything in this question, so X and Y can be anything. Under normal circumstances, I won't TEST the number 1 in PS questions (as it often leads to duplicate answers), but here it's a great option (since we're looking to eliminate 4 answers, multiple TESTs are going to be likely anyway).
We're given information on speed (X km/hour) and distance (Y km). We're asked which of the 5 answer choices CANNOT be the distance traveled.
IF....
X = 2 and Y = 1
Answers A (2-1 = 1) and E (2/2 = 1) are POSSIBLE. Eliminate A and E.
IF....
X = 3 and Y = 1
Answer C ([3-1]/2 = 1) is POSSIBLE. Eliminate C.
IF....
X = 1 and Y = 1
Answer D (1/1 = 1) is POSSIBLE. Eliminate D.

Answer the following multiple choice question by selecting the correct option.
Context: Each ml of ink costs 50 cents so 20 ml costs 20*50 = <<20*50=1000>>1000 cents
There are 2 whiteboards in each class so each class needs 2*1000 cents = <<2*1000=2000>>2000 cents
There are five classes in the block so they all need 5*1*2000 cents = <<5*1*2000=10000>>10000 cents
100 cents make a dollar so 10000 cents make 10000/100 = $<<10000/100=100>>100

Question: Carson is refilling his tires. Each tire can hold 500 cubic inches of air. Two of the tires are completely flat and empty. One tire is 40% full and the last tire is 70% full. If Carson injects 50 cubic inches of air with each pump, how many pumps will it take him to fill all the tires?
A: 29
B: 19
C: 58
D: 14.5
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: First, if the a full tire needs 500 cubic inches of air, then two empty tires need: 500 cubic inches/tire * 2 tires = <<500*2=1000>>1000 cubic inches.
Accordingly, the 40%-full tire needs 500 cubic inches * (100%-40%).
So, we find the 40%-full tire needs 500 cubic inches * (60%) = <<500*(60*.01)=300>>300 cubic inches.
And, the 70%-full tire needs 500 cubic inches * (100%-70%).
So, the 70%-full tire needs 500 cubic inches * (30%)= <<500*(30*.01)=150>>150 cubic inches.
Now add up the needs of all the tires to find the total number of cubic inches needed: 1000 cubic inches + 300 cubic inches + 150 cubic inches = <<1000+300+150=1450>>1450 cubic inches.
Finally, if the pumps each hold 50 cubic inches, the total number of pumps needed is 1550 cubic inches / 50 cubic inches/pump = 29 pumps.

Question: Nutrition and diet affect your metabolism. more energy is required to break down fats and proteins than this?
A: carbohydrates
B: minerals
C: vitamins
D: electrolytes
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: 24.7 Nutrition and Diet Nutrition and diet affect your metabolism. More energy is required to break down fats and proteins than carbohydrates; however, all excess calories that are ingested will be stored as fat in the body. On average, a person requires 1500 to 2000 calories for normal daily activity, although routine exercise will increase that amount. If you ingest more than that, the remainder is stored for later use. Conversely, if you ingest less than that, the energy stores in your body will be depleted. Both the quantity and quality of the food you eat affect your metabolism and can affect your overall health. Eating too much or too little can result in serious medical conditions, including cardiovascular disease, cancer, and diabetes. Vitamins and minerals are essential parts of the diet. They are needed for the proper function of metabolic pathways in the body. Vitamins are not stored in the body, so they must be obtained from the diet or synthesized from precursors available in the diet. Minerals are also obtained from the diet, but they are also stored, primarily in skeletal tissues.

D: mucus
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Tight junctions are common at epithelia, which are sheets of cells that form a boundary between a mass of cells and a cavity or space (a lumen ). The membranes of these cells join together, forming a virtually impermeable barrier to fluid. Tight junctions essentially seal adjacent epithelial cells in a narrow layer just beneath their apical surface, which is the portion of the cell exposed to the lumen. The rest of the cell surface is known as the basolateral surface. Tight junctions prevent integral membrane proteins from moving between the apical and basolateral surface, maintaining the properties of those distinct surfaces. For example, receptor-mediated endocytosis occurs at the apical surface and exocytosis at the basolateral surface.

B: 24%
C: 30%
D: 50%
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: a= amount of arabica coffee
1-a = amount of robusta coffee. because if you subtract a from the 1 ounce, the remaining amount is robusta
therefore:
.6a + .5(1-a) = .55
.6a + .5 - .3a = .55
a= .5
therefore: .5/1 ounce = 50%. Therefore, the answer should be D

Answer the following multiple choice question by selecting the correct option.
Context: Most allergies can be treated with medicines. Medicines used to treat allergies include antihistamines and corticosteroids. These medicines help control the immune system when it attacks an allergen. Sometimes, allergies cause severe symptoms, a condition known as anaphylaxis. For example, they may cause the throat to swell so it is hard to breathe. Severe allergies may be life threatening. They require emergency medical care.

Question: The volume of water in a certain tank is x percent greater than it was one week ago. If r percent of the current volume of water in the tank is removed, the resulting volume will be 90 percent of the volume it was one week ago. What is the value of r in terms of x?
A: x+10
B: 10x+1
C: 100(x+10)
D: 100( x+10/x+100)
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Given that, the water was increased by x percent -> then reduced by r percent -> to 90 percent of what it was one week ago.
Consider, the 100 units of water was increased by 20% to 120 units -> then reduced by 25% of 120 (i.e. by 30 units) -> to 90 units.
i.e. Pick numbers as x = 20% and r = 25%
Substitute x=20 and identify the answer that gives r=25
A) x+10 --20+1=30
b) 10x+1 --200+1=201
c) 100(x+10) --100(20+10)=3000
d) 100( x+10/x+100) --100(20+10/20+100) = 100(30/120)=25
e) 100 ( 10x+1/10x+10) -- 100(200+1/200+10)= 100(201/210)
Hence choice(D) is the answer.

Question: Loisa wants to buy a tablet that costs $450 cash. Since she does not have enough money, the store offered her an installment plan for 12 months. She will pay $100 as a down payment and pay $40 for the first 4 months; then $35 for the next four months; then $30 for the last four months. How much will Loisa save if she will buy the tablet in cash instead of on installment?
A: 56
B: 71
C: 70
D: 69
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Loisa will pay a total of $40 x 4 = $<<40*4=160>>160 for the first 4 months.
She will pay a total of $35 x 4 = $<<35*4=140>>140 for the next four months.
And she will pay a total of $30 x 4 = $<<30*4=120>>120 for the last four months.
Thus, she will pay a total of $100 + $160 + $140 + $120 = $<<100+160+140+120=520>>520 for 12 months including the down payment.
Therefore, Loisa can save $520 - $450 = $<<520-450=70>>70 if she buys the tablet in cash.

Question: What type of orbitals do electrons in successive atoms on the periodic table tend to fill first?
A: orbital lobes
B: outer orbitals
C: high energy
D: low-energy
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Electrons in successive atoms on the periodic table tend to fill low-energy orbitals first. Thus, many students find it confusing that, for example, the 5p orbitals fill immediately after the 4d, and immediately before the 6s. The filling order is based on observed experimental results, and has been confirmed by theoretical calculations. As the principal quantum number, n, increases, the size of the orbital increases and the electrons spend more time farther from the nucleus. Thus, the attraction to the nucleus is weaker and the energy associated with the orbital is higher (less stabilized). But this is not the only effect we have to take into account. Within each shell, as the value of l increases, the electrons are less penetrating (meaning there is less electron density found close to the nucleus), in the order s > p > d > f. Electrons that are closer to the nucleus slightly repel electrons that are farther out, offsetting the more dominant electron–nucleus attractions slightly (recall that all electrons have −1 charges, but nuclei have +Z charges). This phenomenon is called shielding and will be discussed in more detail in the next section. Electrons in orbitals that experience more shielding are less stabilized and thus higher in energy. For small orbitals (1s through 3p), the increase in energy due to n is more significant than the increase due to l; however, for larger orbitals the two trends are comparable and cannot be simply predicted. We will discuss methods for remembering the observed order. The arrangement of electrons in the orbitals of an atom is called the electron configuration of the atom. We describe an electron configuration with a symbol that contains three pieces of information (Figure 6.26): 1. The number of the principal quantum shell, n, 2. The letter that designates the orbital type (the subshell, l), and 3. A superscript number that designates the number of electrons in that particular subshell.
Question: What type of orbitals do electrons in successive atoms on the periodic table tend to fill first?
A: orbital lobes
B: outer orbitals
C: high energy
D: low-energy
Answer:

D

Electrons in successive atoms on the periodic table tend to fill low-energy orbitals first. Thus, many students find it confusing that, for example, the 5p orbitals fill immediately after the 4d, and immediately before the 6s. The filling order is based on observed experimental results, and has been confirmed by theoretical calculations. As the principal quantum number, n, increases, the size of the orbital increases and the electrons spend more time farther from the nucleus. Thus, the attraction to the nucleus is weaker and the energy associated with the orbital is higher (less stabilized). But this is not the only effect we have to take into account. Within each shell, as the value of l increases, the electrons are less penetrating (meaning there is less electron density found close to the nucleus), in the order s > p > d > f. Electrons that are closer to the nucleus slightly repel electrons that are farther out, offsetting the more dominant electron–nucleus attractions slightly (recall that all electrons have −1 charges, but nuclei have +Z charges). This phenomenon is called shielding and will be discussed in more detail in the next section. Electrons in orbitals that experience more shielding are less stabilized and thus higher in energy. For small orbitals (1s through 3p), the increase in energy due to n is more significant than the increase due to l; however, for larger orbitals the two trends are comparable and cannot be simply predicted. We will discuss methods for remembering the observed order. The arrangement of electrons in the orbitals of an atom is called the electron configuration of the atom.

Answer the following multiple choice question by selecting the correct option.
Context: The second podcast was twice as long as the first so 2*45 = <<2*45=90>>90
1 hour is 60 mins. So his 1 hour and 45 min podcast is 60+45 = <<1*60+45=105>>105 minutes long
So far he has downloaded 45+90+105+60 = <<45+90+105+60=300>>300 min
If he converts 300 min to hours then he has 300/60 = <<300/60=5>>5 hours of podcasts downloaded
He has 5 hours of podcasts and his drive is 6 hours so he will need 6 - 5 = <<6-5=1>>1 more hour of podcasts

Question: Toby held a garage sale to raise money to support friends who have lost their jobs. Of all the items that he sold during the garage sale, three of the items he sold made up 75% of the total amount of sales money he earned. He sold a treadmill for $100, a chest of drawers for half as much as he made for selling the treadmill, and he sold a television for three times what he earned for selling the treadmill. What is the total sum of money, in dollars, that Toby made at the garage sale?
A: 1200
B: 590
C: 480
D: 600
Answer:

Answer the following multiple choice question by selecting the correct option.
Context: The chest of drawers sold for half as much as the treadmill, for a price of $100/2= $<<100/2=50>>50.
The television sold for three times what he earned for the treadmill, for a price of $100*3= $<<100*3=300>>300.
For the three items, he raised $100+$50+$300 = $<<100+50+300=450>>450.
If $450 is 75% of the total sum of money that Toby made at the garage sale, then the total amount is $450 / (75/100) = $600.
