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 T=50 + N-40/4 ​, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If T=58​°F, find the number of chirps per minute.

Answer 1

Answer:

The number of chirps per minute is 72

Step-by-step explanation:

Here, using the formula given, we want to find the number N representing the number of chirps per minute.

To get this, we shall simply substitute the value of 58 for T in the equation;

Thus;

58 = 50 + (N-40)/4

58 -50 = (N-40)/4

8 = (N-40)/4

4 * 8 = N -40

32 = N -40

N = 40 + 32

N = 72
