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.

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

Answer:

56°F

Step-by-step explanation:

Given : The formula$F = \frac{n}{4} + 37$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 : $F = \frac{n}{4} + 37$

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

Now we are supposed to substitute n = 75

So,  $F = \frac{75}{4} + 37$

$F = 55.75$

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