The formula to change F to C is F equal 9/5 C + 32. If the temperature is 21.5 C what is it in F?
Umnica [9.8K]

Answer:

F=70.7

Step-by-step explanation:

This is a simple substitution problem.

  1. The formula to change Fahrenheit to Celsius is F=\frac{9}{5}\left(C\right)+32.
  2. They give you C, so substitute it into the problem, which would give you F=\frac{9}{5}\left(21.5\right)+32.
  3. Simplify the right side of the equation by multiplying \frac{9}{5} by 21.5.
  4. Now, add 32 to 38.7, which should have been your answer to the previous step.
  5. You should now have F= 70.7 as your answer.

The tortoise and the hare agree to a re-match. As they begin the race, the tortoise plods along slowly but confidently at 2 ½ mp
Lorico [155]

The tortoise ran a distance of 1.875 miles

The distance traveled or covered is obtained using the relation :

Distance = speed × time

Using the the time it took the hare to reach the finish line:

Time taken = 45 minutes (3/4 hours)

The speed of the tortoise = 2 1/2 mph = 2.5mph

Hence, the distance covered by the tortoise :

(2.5 mph × 3/4 hours) = 1.875 miles

The distance covered by the tortoise is 1.875 miles

Let's simplify the equation:
V=πrh^2 - (πh^3)/3
πrh^2=V + (πh^3)/3
πrh^2=(3V + πh^3)/3
r = (3V + πh^3)/3πh^2
