How can you use a formula for one measurement to write a formula for a different measurement?
1 answer:
Answer:
Write the formula for one measurement, then solve the formula for the different measurement you want to find and use this new formula to find that measurement.
Step-by-step explanation:
We can understand this through an example.
If we need to find the lenght of a rectangle whose width is 4 feet and whose perimeter is 28 feet, we can use a formula for one measurement to write a formula for a different measurement:
- We need to write the formula for the perimeter of a rectangle:
Where "l" is the lenght and "w" is the width.
- Since we know the width and the perimeter of the rectangle and we need to find the lenght, we can solve for "l":
Now we get a new formula for calculate a differente measurement (the lenght of the rectangle).
- Substituting values, we get:

Given length is 91 cm
1 cm = 0.3937 inch
so, 91 cm = 91* 0.3937 = 35.826 inches
1 day = 24 hours
In 24 hours the bamboo grows = 35.826 inches
In one hour it will grow =
= 1.492 inches per hour. Hence the bamboo grows 1.492 inches per hour.

We have to convert hours and seconds in minutes.
1 hour = 60 minutes
so 10 hours = 60 * 10 = 600 minutes.
60 seconds = 1 minute
so 24 seconds = = 0.4 minutes.
Now we have been given the total time as 10 hours, 39 minutes and 24 seconds
So adding all values in minutes, we get
600 + 39 + 0.4 = 639.4 minutes
So Saturn takes 639.4 minutes to complete one rotation
