1.5( x + 4) -3 = 4.5 ( x - 2 )

Hitman42 [59]

Answer:

Step-by-step explanation:

1.5(x + 4) - 3 = 4.5(x - 2)

1.5x + 6 - 3 = 4.5x - 9

1.5x + 3 = 4.5x - 9

3 + 9 = 4.5x - 1.5x

12 = 3x

12/3 = x

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:

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