Answer:

120√6

Step-by-step explanation:

Simplify the 5√8 to 2√2

simplify the √18 to 3√2

so it would be √3 * 2√2 * 5 * 2√2 * 3√2

when a square root of an expression is multiplied by itself:

√3 * 2 * 2* 5 * 2 * 3√2

so as we calculate it, 2 * 2* 5 * 2 * 3 = 120 and √2 * √3 = 6

Hello :)

In this problem, you have to create an equation to figure out the length of each bar. The first bar has two sets of 3 blocks; you can see each set by a color change.

Therefore, this equation would be 2 times 3, since there are 2 sets of 3. This answer equates to 6.

The next one has two bars of four blocks. This means it is 2 times 4, because there are two sets of 4 blocks, and this would constitute as the answer 8.

The second question is a bit tricker. If we look at the first bar, we see that there are 3 blocks per set (noted by color change) and we have 3 of those. If we count all of those up, they have 9 blocks overall. After all, 3 times 3 is nine.

The other problem has 4 blocks a set, and there are three of those. 4 times 3 is 12.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, 10 feet and 6 yards.

We know that, 1 yard =3 feet

Then, 6 yards =18 feet

Now, the fraction for 10 feet and 6 yards is

10/18

= 5/9

Therefore, the fraction is 5/9.

A rectangular, above ground swimming pool is 18 feet long, 9 feet wide, and 54 inches deep. One cubic foot of water weighs about 62.4 pounds. What is the total weight of the water in the pool when it is completely filled? (show/explain how you got your answer)A. 158 lbs
B. 729 lbs
C. 8748 lbs
D. 45489.6 lbs

Answers

What is the total weight of the water in the pool when it is completely filled?

V = L * W * D
V = 18 * 9 * 54/12
V = 18 * 9 * 4.5
V =729  cubic feet

729 cubic feet of water times 62.4 pounds = 45489.6 pounds
