be rectangular prism and rectangular pyramid have the same volume. determine the value of x, the height of the pyramid.

Marina CMI [18]

ANSWER

$x= 9 \: in$

EXPLANATION

The volume of a rectangular prism is given by the formula,

$V = l \times b \times h$
We substitute the dimensions to obtain,

$V = 6 \times 3 \times 12 \: {in}^{3}$

The volume of the rectangular pyramid is,

$V = \frac{1}{3} \times 6 \times 12 \times x \: {in}^{3}$

Equating the two volumes gives,

$\frac{1}{3} \times 6 \times 12 \times x = 6 \times 3 \times 12$

We divide through by 6×12 to get,

$\frac{x}{3}=3$

We solve for x to obtain,

$x = 3 \times 3$

$x = 9 \: in$

What is the slope of the line that passes through the points (2, –3) and (–2, 5)? 2 1/2 -1/2 -2

sergij07 [2.7K]

Answer: The slope is -2.

Step-by-step explanation:

(2,-3)

(-2,5)

Using the two given points, you can find the slope by finding the difference in the y coordinates and diving it by the difference in the x coordinates.

y coordinates: -3 - 5= -8

x coordinates; 2-(-2) = 4

Slope: -8/ 4 = -2
