60% of what number is 348?
The answer is 580.
Using the average rate of change, it is found that the average rate is of:
(1) 2.1 °F per minute
<h3>What is the average rate of change of a function?</h3>
It is given by the <u>change in the output divided by the change in the input</u>.
In this problem:
- At 15 minutes, the temperature was of 90ºF.
- At 45 minutes, the temperature was fo 153ºF.
Hence, in 30 minutes, the temperature increased 63ºF, hence the rate is given by:
r = 63/30 = 2.1 °F per minute.

Answer:
Step-by-step explanation:
Let the shorter side be x
Then the longer side is x + 1
<u>Perimeter is:</u>
- P = 2( x + x + 1) = 2(2x + 1) = 4x + 2
The value of perimeter is at most 60 meters. P ≤ 60.
<u>Solve the inequality:</u>
- 4x + 2 ≤ 60
- 4x ≤ 58
- x ≤ 58/4
- x ≤ 14.5
Since x is the integer, its greatest value is 14 m
