Question

The formula f= n/4 + 37 estimates the temperature F in degrees Fahrenheit when crickets chirp n times per minute. Use the formula to estimate the

temperature when n = 75 chirps/min. Round to the nearest whole number, if necessary.

b) 53mc009-3.jpg
c) 56mc009-5.jpg
d)58mc009-2.jpg

Answer 1

the answer is C when you plug in 75 for n you get 75/4+37 which equals 55.75 when rounded to the nearest whole number it is 56 which is C. Hope that helps

Answer 2

56°F

Explanation:

Given : The formula
`F = (n)/(4) + 37`estimates the temperature F in degrees Fahrenheit when crickets chirp n times per minute.

To Find: Use the formula to estimate the temperature when n = 75 chirps/min.

Solution:

Formula :
`F = (n)/(4) + 37`

Where F in degrees Fahrenheit when crickets chirp n times per minute.

Now we are supposed to substitute n = 75

So,
`F = (75)/(4) + 37`

`F = 55.75`

Hence the temperature is 56°F when n = 75 chirps/min.
