To find the rates, you need to find out how much money each booth made per hour. You have to calculate how much money they made in one hour.
Sixth Grade:
Seventh Grade:
Eight Grade:
Therefore since the Sixth graders made the most money per hour, they had the highest rate for raising money.
Sent a picture of the solution to the problem (s). Used the hint and substituted all the know quantities.
Coplanor lines that never intersect
The answer would be 8.975 because 39 divided by 40 is 0.975.
Answer:
Using 3.14 as pi, the answer would be 56.52, and using just pi (as in the input on a calculator) would be 56.54867.
Step-by-step explanation:
The equation for circumference of a circle is C = πd, C representing the circumference and d representing the diameter. Since the equation shows the radius, the equation can also be C = 2πr, since the radius is half of the diameter. Multiply nine by two to get eighteen. 18 times 3.14 = 56.52.
