The height of a cylinder is equal to the diameter of the base What expression represents the volume of the cylinder, in cubic un
Sveta_85 [38]

Answer: 3 units

Step-by-step explanation:

the volume of a cone C = πr²h/3

C = 18π, h =2x, r = diameter/2 = 2x/2 =x

18π = π* x²* 2x/3

divide through by π

18 = x² * 2x/3

multiply through by 3

54 = 2x³

divide through by 2

27 = x³

x =∛27 = 3

x = 3 units = radius

Solve for x: -7x+2=-4x-7
Zielflug [23.3K]

Answer: x = 3

Step-by-step explanation:

First you need to start by adding positive 4x to both sides since the 4x is a negative.  4x + (-7x) = -3x.  Then it is just simply -3x+2 = -7.  Since 2 is a positive number subtract both both sides by 2.  Then you should get -3x = -9.  Then divide both sides by -3 and the answer is x = 3.

It takes Emma 3/4 minutes to ride her bike a distance of 1/8 miles. What is Emma's average speed in miles per minute?
sp2606 [1]

Answer:

The answer is 1/6

Step-by-step explanation:

1/8 miles in 3/4 minutes

then, that means in 1 minute ( 1 min = 3/4 * 4/3) Emma will ride a distance of (1/8)*(4/3)= (1*4)/(8*3)= 1/6.

The answer is 1/6 (in 1 min she will ride 1/6 miles).

Hope that useful for you.
