Answer:
The percent of increase in height of the stalks is 20%.
Step-by-step explanation:
The general formula for a percent increase is as follows: (Original Amount - New Amount/Original Amount) x 100. The original height of the stalks was 60 inches tall. The new height of the stalks is 72 inches. In the numerator of our fraction, we take 72-60 to get 12. Our denominator is the original amount, or 60. This gives us an overall fraction of 12/60, which when we divide gives us 0.2. Once we multiply our decimal by 100, we get an overall percent increase of 20%.

Answer:
12 inches
First choice
Step-by-step explanation:
Solve using the formula for circumference.
C = 2πr
"C" is the circumference, which we know C = 75 in.
π = 3.14 in this problem.
"r" is the radius, which we are finding.
Substitute the numbers you know for the variables of the formula.
C = 2πr
(75in) = 2(3.14)r
Since we are finding "r", we need to isolate it. If we divide the right side by 2(3.14), it cancels out and "r" will be alone.
Put the variable on the left side for standard formatting.
Now simplify the fraction.
2 times 3.14 is 6.28
Divide the top by the bottom
r = 11.9426752 in Exact decimal answer
r ≈ 12in Rounded answer to nearest inch
24 minutes.
Let me explain.
The lawn can be any size, but for the purpose of simplicity, let's say it's 240 square meters.
Peter mows 6 square meters per minute if he mows 240 square meters in 40 minutes.
John mows 4 square metres each minute if he mows 240 square metres in 60 minutes.
They'll mow 10 square meters per minute if they work together.
As a result, mowing the entire lawn will take them 24 minutes.
(Note that the location is irrelevant as long as we know how long each man takes to complete the task separately.) The answer would be the same if the field was 1 million hectares in size.)
I hope this helps.
