Question

dolbears law states the relationship between the rate at which snowy tree crickets chirp and the air temperature of their environment. the formula is t = 50+\frac{n - 40}{4}, where t is a temperature in degrees fahrenheit and n is a number of chirps per minute. if t = 56°f, find the number of chirps per minute.
n = □ (type an integer or a decimal.)

Explanation:

Step1: Substitute T value into formula

Given $T = 56$ and $T=50+\frac{N - 40}{4}$, we substitute $T$:
$56=50+\frac{N - 40}{4}$

Step2: Isolate the fraction term

Subtract 50 from both sides:
$56 - 50=\frac{N - 40}{4}$
$6=\frac{N - 40}{4}$

Step3: Solve for N

Multiply both sides by 4:
$6\times4=N - 40$
$24=N - 40$
Then add 40 to both sides:
$N=24 + 40$
$N = 64$

Answer:

64
