Question

​Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is Upper T equals 50 plus N minus 40 Over 4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If T equals=58​°F, find the number of chirps per minute.

Answer 1

I assume that if we write the equation in its mathematical form it will appear like this:
                                  T = 50 + (N - 40)/4
Substituting the value of T given,
                                  58 = 50 + (N-40)/4
The value of N from the generated equation above is equal to 72. Therefore, the Snowy Tree Crickets chirp 72 times per minute at a temperature of 58°F.

Answer 2

Answer:

72 chirps per minute.

Step-by-step explanation:

Dolbear's law state the relationship between the rate at which Snowy Tree Cricket chirp and the air temperature of their environment.

The formula that represents this situation is T = 50 + $\frac{(N-40)}{4}$

Where T is the temperature in degrees Fahrenheit and N is a number of chirp per minute.

Now we have to calculate the number of chirp per minute if T = 58° F

By replacing T = 58 in the given relation.

58 = 50 + $\frac{(N-40)}{4}$

58 - 50 = $\frac{(N-40)}{4}$

8 = $\frac{(N-40)}{4}$

Now we multiply the equation by 4 on both the sides.

(8)(4) = $\frac{(N-40)(4)}{4}$

32 = N - 40

N = 40 + 32

N = 72

Therefore, the rate at which Snowy tree cricket chirp will be 72 chirps per minute at T = 58° F
