Okay? Is there anything else to the question?
Answer:
C = F - 32 /(9/5)
Step-by-step explanation:
F = (9/5)C + 32
Subtract 32 from both sides
F - 32 = (9/5)C + 32 - 32
F - 32 = (9/5)C
Divide both sides by (9/5)
F - 32/(9/5) = (9/5)C/(9/5)
F - 32/(9/5) = C
C = F - 32 /(9/5)
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:
25 kilograms
Step-by-step explanation:
Answer:
a) $525 CAD
b) $168.30 per day
c) $38.05
Step-by-step explanation:
a) <u> 1 USD </u> = <u> 500 </u>
1.05CAD x
cross-multiply: x = $525 CAD
b) 504.90 / 3 = 168.30 per day
c) <u> 1 USD </u> = <u> x </u>
1.05CAD 39.95
cross-multiply: 1.05x = 39.95
x = 39.95 / 1.05
x = $38.05 USD
