1 answer:
Vesna [10]2 years ago
6 0

Answer:

x=11

Step-by-step explanation:

We know that angles on a straight line equal 180 degrees, so we know that 8x+10+7x+5 = 180.

Simplify

15x+15=180

Solve

<em>Take</em><em> </em><em>away</em><em> </em><em>1</em><em>5</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

15x = 165

<em>Divide </em><em>1</em><em>6</em><em>5</em><em> </em><em>by</em><em> </em><em>15</em>

x = 11

A cylinder and a cone have the same base and height. The cylinder can hold about 4,712 Centimeters cubed of sand. Jared says tha
klasskru [66]

Answer:

C. Jared is not correct because the cone and the cylinder have the same base and height so the cone holds 4,712/3≈1,571 centimeters cubed of sand.

Step-by-step explanation:

We have a cone and a cylinder with the same base and height.

We can express the volume of the cylinder as:

V_{cyl}=\pi r^2H

being r the radius and H the height.

The volume of the cone can be written as:

V_{con}=\dfrac{\pi}{3}r^2H=\dfrac{V_{cyl}}{3}

As they have the same base and height, we know that the volume of the cylinder is 3 times the volume of the cone.

If the volume of the cylinder is 4,712 cm^3, then the volume of the cone is:

V_{con}=\dfrac{V_{cyl}}{3}=\dfrac{4,712}{3}\approx1571
