To answer your questions, we can use the given formula: C = T - 40, where C represents the number of chirps and T represents the temperature in degrees Fahrenheit.
A. How many chirps does the cricket make at 70 degrees Fahrenheit?
To find the number of chirps, we substitute T = 70 into the formula:
C = T - 40
C = 70 - 40
C = 30
Therefore, the cricket would chirp 30 times at 70 degrees Fahrenheit.
B. What is the temperature if the cricket chirps 40 times in 1 minute?
To find the temperature, we need to rearrange the formula and solve for T. Let's substitute C = 40 and the time period in minutes = 1:
C = T - 40
40 = T - 40
T = 40 + 40
T = 80
Therefore, the temperature would be 80 degrees Fahrenheit if the cricket chirps 40 times in 1 minute.
