A parasail is 1/20 of a meter above water then after 10 mins the parasol is 1/50 of a meter above water what is the change in height
To find the change in height, we need to subtract the initial height from the final height.
Initial height = 1/20 m
Final height = 1/50 m
Change in height = Final height - Initial height
Change in height = (1/50) - (1/20)
Change in height = 0.02 - 0.05
Change in height = -0.03 m
Therefore, the change in height is -0.03 meters.
or 1/20 * 5/5 = 5/100
and 1/50 * 2//2 = 2/100
then
2/100 - 5/100 = -3/100
which is of course -0.03
Yes, you are correct. Another way to calculate the change in height is by converting both fractions to have a common denominator of 100.
Initial height = 1/20 * 5/5 = 5/100
Final height = 1/50 * 2/2 = 2/100
Change in height = Final height - Initial height
Change in height = (2/100) - (5/100)
Change in height = -3/100
Change in height = -0.03
Therefore, the change in height is indeed -0.03 meters.
To find the change in height, we need to subtract the initial height from the final height.
Initial height above water = 1/20 meter
Final height above water = 1/50 meter
Change in height = Final height - Initial height
= (1/50) - (1/20)
= (1/50) - (2/100)
= (1/50 - 2/100)
= (2/100 - 1/50)
= (4/200 - 2/200)
= (4 - 2)/200
= 2/200
= 1/100 meters
Therefore, the change in height is 1/100 meter.
