Answer:

B. A rectangle, 4 in by 3 in

Step-by-step explanation:

The foam has the shape of a cuboid with base of 10 in by 4 in and height of 3 in.

The foam has a front elevation of a rectangle with dimension of 4 in by 3 in. It has a left elevation of dimension 10 in by 3 in and a plan of dimension 10 in by 4 in.

If the foam is cut along the red line, the exposed face would be the same as the shape of the front elevation. Hence the shape of the cross section would be a rectangle with dimension of 4 in by 3 in.

notsponge [240]

Answer:

w = V/lh

Step-by-step explanation:

The volume of a rectangular prism is calculated using the formula V = lwh, where V is the volume of the prism, l and w are the length and width of the base of the prism, respectively, and h is the height of the prism.

Rewrite the formula to find the width of the base of the prism if the volume, length of the base, and height of the prism are already known.

volume of a rectangular prism,V = lwh

Where,

l = length of the base of the prism

w = width of the base of the prism

h = height of the prism

Rewrite the formula to find w

V = lwh

w = V/lh

That is,

width of the base of the prism = volume of the prism divided by length of the base of the prism multiplied by height of the prism

If you multiply an inequality by a negative number _____.

sergeinik [125]

Answer:

<h2>A. Switch the inequality sign</h2>

Step-by-step explanation:

When multiplying, you must switch the inequality sign. This is also true when dividing.

EXAMPLE 1:

-4r < -21

Note: We reversed the inequality sign when we divided by -4

r > 5 1/4

EXAMPLE 2:

x/-5 <u>></u> 7

Note: We reversed the inequality sign when we multiplied by -5

x <u><</u> -35

I'm always happy to help :)
