A company make concrete bricks shaped like rectangular prisms.

1 answer:

3 0

Each brick contains 10*9*4=360 inches cubed. Since 1 brick = 360in³, we want to know how much 360in³ goes into 18000in³ (or how many bricks go into 18000in³). To do this, we simply divide 18000in³ by 360in³ to get 50 bricks

If 16+4x is 10 more than 14, what is the value of 8x?

sattari [20]

16 + 4x = 10 + 14

16 + 4x = 24.

4x = 24 - 16

4x = 8

x = 8 ÷ 4

x = 2

8x = 2 × 8

8x = 16

Final answer = 16.

Martina drove 715 miles in 13 hours. at the same rate, how long would it take her to drive 495 miles?

Natali5045456 [20]

First you need to get the unit rate by dividing 715 by 13, getting 55 miles per hour. You then will need to divide 495 by 55 to get the answer of 9

In t hours the train has traveled s miles. Find the formula for v, the speed of the train (in mph) in terms of t and s. Find the

Digiron [165]

Answer:

Part 1 .

As per the given statement: In t hours the train has traveled s miles.

Distance of the train = s mile

Time = t hours

Formula for :

Speed of the train(v) = $\frac{\text{Distance of the train}}{\text{Time}}$

$v = \frac{s}{t}$ mph .....[1]

Substitute the value of t = 3 hours and s = 180 miles in [1], to solve for v;

$v = \frac{180}{3} = 60 mph$

Therefore, the speed of the train(v) is, 60 mph

Part 2.

Similarly,

The formula for speed of the train (v) is given by;

$v =\frac{s}{t}$

Substitute the value of t = 2.5 hours and s = 225 miles to solve for v;

$v = \frac{225}{2.5} = 90 mph$

Therefore, the speed of the train(v) is, 90 mph
