Fred, Norman, and Dave own a total of 128 comic books. If Dave owns 44 of them, what is the average (arithmetic mean) number of comic books owned by Fred and Norman?

Step-by-step explanation:

Given

Represent Fred with F; Norman with N and Dave with D.

Required

Determine the arithmetic mean of F and N

First, we have that:

Substitute 44 for D

Subtract 44 from both sides

Arithmetic mean of F and N is calculated as follows:

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
