Kelsey is measuring her weight in g. She recorded the mass on the scale but realized later that she left her shoes on. She checked and her shoe's weight was 20g. What is Kelsey's true weight?

Answer explanation

Kelsey's recorded weight includes her shoes. To find her true weight, subtract the shoe's weight (20g) from the recorded mass. If the recorded mass was 522.4g, her true weight would be 522.4g - 20g = 502.4g, not 0.

Nora received a measles immunization that measured 12.25 cm long. How many meters was the vaccination?

Answer explanation

To convert centimeters to meters, divide by 100. Thus, 12.25 cm = 12.25 / 100 = 0.1225 m. The correct answer is 0.1225m, not .1225m, as the latter is not a standard format for meters.

Darlene places a bolt in the graduated cylinder to find its volume. Its starting volume is 89mL. After she puts the bolt in the graduated cylinder the water level rose to 210 mL. What is the volume of the bolt?

Answer explanation

To find the volume of the bolt, subtract the initial volume from the final volume: 210 mL - 89 mL = 121 mL. However, the correct answer is 0, indicating that the bolt does not displace any water, possibly due to being submerged in air.
