Answer:
a) t = 5/24 c + 45.
b) 76 degrees F.
c) c = (24/5) t - 216.
Step-by-step explanation:
a) The rate of temperature change to number of chirps per minute = (80-70) / (168 - 120)
= 10 / 48 = 5/24.
So we can write the equation as t = 5/24 c + b where t = temperature, c = number of chirps and b is a constant.
Plugging in the values t = 70 and c = 120 we can find the value of b:
70 = (5/24) * 120 + b
b = 70 - 5*5
b = 45
So the required equation is
t = 5/24 c + 45.
b) When number of chirps is 150:
Temperature t = (5 *150) / 24 + 45
= 76 degrees F.
c) Reversing the process
t = 5/24 c + 45
5/24 c = t - 45
c = (24/5) t - 45 * 24/5
c = (24/5) t - 216.

Hello!
The easiest way to solve this would be to convert 6 4/5 to a decimal. We know that to convert a fraction to a decimal, we must divide the numerator by the denominator.
4 / 5 = 0.8
0.8 + 6 = 6.8
So, 6 4/5 is 6.8 as a decimal.
See how it's easier now that we've converted the mixed number to a decimal?
There could be many numbers between 6.8 and 7. Some examples are:
6.81, 6.82, 6.83, 6.9, etc.
