A parasil is 1/20 of a meter above the water. Then, after 10 minutes, tge parasil is 1/50 of a meter above the water. What is the change in height?
To find the change in height, we subtract the initial height from the final height.
Given:
Initial height = 1/20 meter
Final height = 1/50 meter
Change in height = Final height - Initial height
Change in height = (1/50) - (1/20)
To subtract fractions, we need to find a common denominator.
Common denominator of 20 and 50 = 100
Change in height = (1/50) - (1/20) = (2/100) - (5/100)
Now that the fractions have the same denominator, we can subtract them.
Change in height = 2/100 - 5/100 = -3/100
So, the change in height is -3/100 meters.
To find the change in height, we'll subtract the initial height from the final height.
Given that the parasil is initially 1/20 of a meter above the water and after 10 minutes it is 1/50 of a meter above the water:
Final height = 1/50 meters
Initial height = 1/20 meters
Change in height = Final height - Initial height
Substituting the values:
Change in height = (1/50) - (1/20)
Next, we need to convert the fractions to have a common denominator. The lowest common denominator for 20 and 50 is 100.
Change in height = (1/50) * (2/2) - (1/20) * (5/5)
Change in height = 2/100 - 5/100
Change in height = (2 - 5)/100
Change in height = -3/100
Therefore, the change in height is -0.03 meters or -3 centimeters.
