Answer: the math definition would be (of a quantity) able to assume different numerical values.
The skateboard would cost d-2h dollars because when the amount of money for both of the helmets is subtracted from the total dollar amount, then that leaves the amount that was paid for the skateboard since Timmy did not buy anything else.
Hello from MrBillDoesMath!
Answer: 30
Discussion:
The area of a circle of radius R is given by the formula
Pi * R^2
We are given that the area is 225 Pi (Not 255 Pi as stated by the author)
Pi * R^2 = 225 * Pi
Divide both sides by Pi :
R^2 = 225 ---> R = 15
The diameter is twice the radius so the diameter = 30.
