Answer:

Answer C. V = 88 ft³

Step-by-step explanation:

The general formula for the volume V of a pyramid:

V = 1/3 * B * h

The volume V of a pyramid is one-third the area of the base B times the height h.

  • Base B = 8 * 3 = 24 ft²
  • Height h = 11 ft

V = 1/3 * 24 * 11

V = 1/3 * 264

V = 88 ft³

Which is answer C.

R = radius of basketball
r = radius of tennis ball 
R = 3.6r cube both sides
the ratio of the radii is 1: 3.6
cube both sides to find the ratio of the volumes 
1 : 46.656 ( this many times greater)

Consider the expressions 3x(x − 2) + 2 and 2x2 + 3x − 18.
Rzqust [24]

Answer:

See answer below

Step-by-step explanation:

For the first expression

3 x (x - 2) + 2 = 3 x^2 - 6 x + 2

evaluated at x= 4 we get: 26

and for x = 5 we get 47.

For the second expression

2 x^2 + 3 x - 18

we get the exact same values when doing the evaluation at these two points.

Based on those results, one may think the expressions may be equivalent, but they are not equivalent. Because at any other x-value, their results are different. See for example that for x = 0 the first one gives "2" while the second one gives -18.

A bookkeeper has a balance of $83.92. If she collects $76.75
kotegsom [21]

Answer:

The bookkeeper already has a balance of 83.92.  She collects 76.75 so that's 83.92+76.75 which equals to 160.67.  Then she pays out 38.58 so that's a deduction to what she already has.  160.67-38.58=122.09.

SO the bookkeeper has $122.09 left.
