Finding x.
Suzette ran = x
Suzette biked = 4x
7 = x + 4x --) 7 = 5x --) 1.4 = x
Suzette ran for 1.4 hours
Finding y.
Quickest way is to use Suzette biked = 4x and substitute the x for 1.4 to find how much she biked.
4 x 1.4 = 5.6
1.4 + 5.6 = 7 hours the total time exercising
And the mileage adds up to.
5(1.4) + 20(5.6) = 119
Answer:
1/2
Step-by-step explanation:
y2 - y1. over. x2 - x1
The median is the middle when numbers are in order from least to greatest.

Answer:
Hi there!
The correct answer to this question is: The <u>side length</u> of the square base is 18 inches and the <u>height</u> of the pyramid is 9 inches.
Step-by-step explanation:
The equation to find the volume of a square pyramid is V= (b^2)(h/3)
we are given the volume to be 972 inches cubed, additionally we know that the base of the square is x inches, the height is x/2
then we plug in and we get 972= (x^2)(x/2/3)
then you simplify to 972 = x^3 / 6 then you multiply six on both sides and you get x^3 = 5832
cube root on both sides and you get x = 18 that means the base is 18 inches and the height is x/2 then you plug 18 in and you get the height to be 9 inches.
Answer:
Its 42 degrees
