Answer:

The problem stats you cannot compress the balls; so you can not round up. You must round down. That means 4 x4 x4. There will be 16 balls per layer and 4 layers. So 48 balls.

The volume of the box is 12%5E3 inches.

 

You are told the diameter of a ball is 2.5 inches. So the radius of a ball is 1.25 inches

The volume of each ball is %284%2F3%29pi%2Ar%5E3

Subtract the volume of 16 balls from the volume of the box to get the volume of the packing bead material

To get the percentage of beads to box, divide the bead volume by the box volume and multiply by 100%

Number 16 is D & 15 is D because in number 16 8y can’t equal X but 8 can be in the X&Y’s place. As for number 15 the correct equation is 2y=0-4.

3. When you calculate and find the answer as a decimal, then make it into a percentage

So if... you divide 7.5 divided by 36, you get the decimal of 0.2, and when you move the decimals two places only, you get your answer of 20%.

inna [77]

Answer:

Think about it

Step-by-step explanation:

If you made $20 in 2 hrs you made $10 per hour

To find out how much you make per certain number of hrs multiply $10 by the number of hours

The equation is y = 10x + 0 <-- this is also answer to number 4

10x is the constant of proportionality I think.
