If a concrete mix contains 1-1/2 cubic feet of gravel, 1/2 cubic foot of water,

Karolina [17]

Answer:

The correct answer is "50%".

Step-by-step explanation:

The given values are:

Gravel,

= $(1-\frac{1}{2} )$

Water,

= $\frac{1}{2}$

Cement,

= 1

Sand,

= 2

Now,

The total mixture will be:

= $Gravel+Water+Cement+Sand$

By substituting the values, we get

= $(1-\frac{1}{2} )+\frac{1}{2} +1+2$

= $\frac{1}{2} +\frac{1}{2} +1+2$

= $4 \ cubic \ feet$

hence,

The percentage of sand will be:

= $\frac{Sand}{Total}\times 100$

= $\frac{2}{4}\times 100$

= $50$ %

The plot below shows the volume of paint left in 444 cans.

yKpoI14uk [10]

The amount of paint that would be contained in each of the can would be 8.

<h3>How to solve for the amount of paint.</h3>

Using the information in the question we have the following

We have to solve the equation as

(2 1/2) + 2(4) + 1(5 1/2) =

2.5 + 8 + 5.5

= 16

Each of these would have to hold 16/2 = 8 pints.
