Find the volume of a pyramid with a square base, where the side length of the base is 16.6\text{ m}16.6 m and the height of the pyramid is 10.1\text{ m}10.1 m. Round your answer to the nearest tenth of a cubic meter.

55.4 m^3

Step-by-step explanation:

The volume of a pyramid of base area A and height h is V = (1/3)(A)(h).

Here, V = (1/3)(16.6 m)^2 * 10.1 m  = 55.4 m^3

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
