Answer:
Option A) The temperature of F degrees Fahrenheit converted to degrees Celsius
Step-by-step explanation:
The formula to convert temperature from degrees Fahrenheit to degrees Celsius is:

If we have the measure of temperature in degrees Fahrenheit we can convert that temperature to degrees Celsius by substituting it in place of F. For example, if we want to convert 50 degrees Fahrenheit to degrees Celsius just replace F in the above formula by 50 and C(F) will give the equivalent temperature in degrees Celsius.
So, C(F) represents the temperature of F degrees Fahrenheit converted to degrees Celsius. Option A gives the correct answer.
Assuming it's a constant rate, there is a four hour difference from t=1 and t=5, so subtract the difference in depth (0.03 - 0.06) and divide that by four.
-0.03/4 = -0.0075
So your change in depth in feet per hour is -0.0075

So you know that the carpenter has a board that is 18.5ft long and he wants to cut 1.75ft pieces.
Assume that <em>x</em> is the amount of boards he cuts,
1.75<em>x</em> = 18.5
Isolate <em>x</em> by dividing each side by 1.75.
<em>x </em>= 18.5/1.75 = 10.57 pieces.
