The second stick is 3 x 2 = <<3*2=6>>6 centimeters long. The third stick is 6 - 1 = <<6-1=5>>5 centimeters long. Thus, Jazel's sticks are 3 + 6 + 5 = <<3+6+5=14>>14 centimeters long when they are put together. #### 14

The first ball is a third of the size of the third ball, so it used 27 / 3 = <<27/3=9>>9 feet of yarn. The second ball is twice the size of the first ball, so she used 9 * 2 = <<9*2=18>>18 feet of yarn. #### 18

Mickey and Johnny are having a contest to see who can run around their block the most. One time around the block equals 200 meters. Johnny runs around the block 4 times. Mickey runs around the block half as many times as Johnny. What is the average distance run by Johnny and Mickey?

Mickey runs around the block twice because half of 4 is <<4/2=2>>2. Mickey runs 400 meters in total because 2 times 200 equals <<2*200=400>>400. Johnny runs 800 meters because 4 times 200 equals <<4*200=800>>800. In total, they run 1200 meters because 400 plus 800 equals 1200.

null

First find the total number of people by adding the number of passengers and flight crew: 30 people + 5 people = <<30+5=35>>35 people Then find the total number of bags by doubling the total number of people: 35 people * 2 bags/person = <<35*2=70>>70 bags Then find the fuel increase caused by the people by multiplying their number by the fuel increase per person: 35 people * 3 gallons/mile/person = <<35*3=105>>105 gallons/mile Then multiply the number of bags by the fuel increase per bag to find the total fuel increase they cause: 70 bags * 2 gallons/mile/bag = <<70*2=140>>140 gallons/mile Now add the fuel increases to the base fuel consumption to find the total fuel needed per mile: 140 gallons/mile + 105 gallons/mile + 20 gallons/mile = <<140+105+20=265>>265 gallons/mile Now multiply the fuel consumption per mile by the number of miles flown to find the total amount of fuel needed: 265 gallons/mile * 400 miles = <<265*400=106000>>106,000 gallons of fuel #### 106000

Use the model to determine whether sodium fluoride is an elementary substance or a compound. Step 1: Interpret the model. . Use the legend to determine the chemical element represented by each color. The colors and atomic symbols from the legend are shown in the table below. The table also includes the names of the chemical elements represented in the model. You can see from the model that sodium fluoride is composed of fluorine atoms and sodium atoms bonded together. Step 2: Determine whether the substance is an elementary substance or a compound. You know from Step 1 that sodium fluoride is composed of two chemical elements: fluorine and sodium. Since sodium fluoride is composed of multiple chemical elements bonded together, sodium fluoride is a compound.

Complete the statement. Nitrogen is ().
[ "a compound", "an elementary substance" ]
B
Use the model to determine whether nitrogen is an elementary substance or a compound. Step 1: Interpret the model. In the ball-and-stick model shown above, both of the balls are the same color: . The legend shows that blue represents the chemical element with the atomic symbol N. So, the model shows you that a molecule of nitrogen is composed of one chemical element. Step 2: Determine whether the substance is an elementary substance or a compound. You know from Step 1 that nitrogen is composed of only one chemical element. So, nitrogen is an elementary substance.
