Question

There's a roughly linear relationship between the number of times a species of cricket will chirp in one minute and the temperature outside. For a certain type of cricket, this relationship can be expressed using the formula T=0.27c+39, where TT represents the temperature in degrees Fahrenheit and cc represents the number of times the cricket chirps in one minute. What is the meaning of the cc-value when T=93?

Answer 1

Answer: the cricket chirps about 200 times per minute.

=========================================================

Step-by-step explanation:

c = number of chirps per minute

T = temperature in Fahrenheit

We're given that T = 93.

Replace T with 93, then solve for c.

T=0.27c+39

93=0.27c+39

0.27c+39 = 93

0.27c = 93-39

0.27c = 54

c = 54/(0.27)

c = 200

When the temperature is 93 degrees Fahrenheit, the cricket chirps about 200 times per minute.
