What is the length of a rectangular prism if the volume is 2,830.5 cubic meters, the width is 18.5 meters, and the height is 9 meters?

length = 17 meters

Step-by-step explanation:

The formula for volume of a rectangular prism is

V = L*W*H     where L is length, W is width, and H is height.  We are given V, w, and h, so plug those values in and solve for l

2,830.5 = L(18.5)(9)

 2,830.5 = 166.5L     (simplify the right side    18.5*9 = 166.5 )

     2,830.5/166.5 =  L     (divide both sides by 166.5 to isolate L)

     17 = L       (simplift the left side)

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
