Suppose x=0.5(300-x). what is the value of x?

Sonbull [250]

Expand

x = 150 - 0.5x

Add 0.5x to both sides

x + 0.5x = 150

Simplify x + 0.5x to 1.5x

1.5x = 150

Divide both sides by 1.5

x = 150/1.5

Simplify 150/1.5 to 100

x = 100

A cone and 2 cylinders are shown below. The volume of the cone is 15 cubic centimeters. Each of the 2 cylinder has the same heig

shutvik [7]

Answer:

90 $cm^{3}$

Step-by-step explanation:

Given:

The volume of a cylinder =15 $cm^{3}$

Height of cone = Height of either cylinder

Radius of cone=Radius of either cylinder

Formula:

Volume of a cone = $\pi r^{2}h/3$

Volume of a cylinder = $\pi r^{2}h$

To find: Combined volume of both cylinders.

The volume of a cylinder =15 $cm^{3}$

$\pi r^{2}h/3$ =15 $cm^{3}$

$\pi r^{2}h$ =15 * 3 $cm^{3}$

$\pi r^{2}h$ =45 $cm^{3}$

[As

Height of cone = Height of either cylinder

Radius of cone=Radius of either cylinder]

$\pi r^{2}h$ =45 $cm^{3}$ is the volume of one cylinder.

Combined volume of cylinder = 2* Volume of cylinder = 2*45 =90 $cm^{3}$
