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 $t = 58^{circ}f$, find the number of chirps per minute.
$n=\text{type an integer or a decimal.}$

Explanation:

Step1: Sustituir el valor de T en la fórmula

Dada la fórmula $T = 50+\frac{N - 40}{4}$, y $T = 58$. Sustituimos $T$:
$58=50+\frac{N - 40}{4}$

Step2: Isolar la fracción

Restamos 50 de ambos lados de la ecuación:
$58 - 50=\frac{N - 40}{4}$
$8=\frac{N - 40}{4}$

Step3: Despejar N

Multiplicamos ambos lados por 4:
$8\times4=N - 40$
$32=N - 40$
Luego sumamos 40 a ambos lados:
$N=32 + 40$
$N = 72$

Answer:

72
