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)
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.
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?
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.

To find the change in height, we subtract the initial height from the final height.
Final Height - Initial Height = Change in Height
Given:
Initial height = 120 meters
Final height = 150 meters
Change in Height = 150 meters - 120 meters = 30 meters
So, the change in height is 30 meters.
To calculate the change in height, we need to find the difference between the two heights.
Given:
Initial height (h₁) = 120 meters
Final height (h₂) = 150 meters
To find the change in height, we subtract the initial height from the final height:
Change in height = h₂ - h₁
Change in height = 150 meters - 120 meters
Change in height = 30 meters
Therefore, the change in height of the parasail is 30 meters.
