A company makes concrete bricks shaped like rectangular prisms. Each brick is 13 inches long, 5 inches wide, and 4 inches tall. If they used 11,700 in^3 of concrete, how many bricks did they make?

45 bricks

Step-by-step explanation:

First we need to find the volume of one brick. The bricks are rectangular prisms. The volume formula for rectangular prisms is:

V=l*w*h

The bricks are 13 inches long, 5 inches wide and 4 inches high.

l=13 inches

w=5 inches

h=4 inches

V= 13 inches * 5 inches * 4 inches

V=65 inches^2 * 4 inches

V=260 inches ^3

Each brick has a volume of 260 inches^3. We know they used a total of 11,700 inches^3 of concrete. The question asks us to find how many bricks they made. We must divide the volume of concrete used by the volume of one brick.

concrete volume / one brick volume

concrete volume= 11,700 in^3

one brick volume= 260 in^3

11,700 in^3 / 260 in^3

11,700/260

45

They made 45 bricks.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
