A parasail is 120 of a meter above the water. Then, after 10 minutes, the parasail is 150 of a meter above the water. What is the change in height?(1 point)

Answer 1

The change in height can be calculated by subtracting the initial height from the final height.

Change in height = Final height - Initial height
Change in height = (150/100) m - (120/100) m
Change in height = 1.5 m - 1.2 m
Change in height = 0.3 meters

Therefore, the change in height is 0.3 meters.

Answer 2

A parasail is 1/20 of a meter above the water. Then, after 10 minutes, the parasail is 1/50 of a meter above the water. What is the change in height?

Answer 3

The change in height can be calculated by subtracting the initial height from the final height.

Change in height = Final height - Initial height
Change in height = (1/50) m - (1/20) m

To subtract these fractions, we need a common denominator. The common denominator of 20 and 50 is 100.

Change in height = (1/50) * 100 - (1/20) * 100
Change in height = 2 - 5
Change in height = -3

Therefore, the change in height is -3/100 meters or -0.03 meters.
