5. A rectangular pool ha a length that is 13 meters longer than its width. perimeter is74 meters. What is the width Its of this pool?

Answers

Good evening Brian,

For this problem, let's look at what we're given. So we have a pool with a length that is 13 m (meters) longer than its width, and we're given the perimeter, or distance around the entire pool, which is 74 m.

We know that the pool has a rectangular shape and that the perimeter of a rectangle is width + length + width + length ⇒ 2(W) + 2(L).

Given the information provided, we can rewrite the equation to fit this problem. Since we're told that the length is equal to 13 m + the width, so we can represent the length as W +13 m. We can now rewrite the perimeter equation to be:

2(w) + 2 (w + 13 m) ⇒ 2(w) + 2(w) + 2(13 m) ⇒ 4(w) + 26 m = 74 m.

We're down to one variable now so this should be easy. Subtract 26 m from both sides,

4(w) = 48 m

Now divide each side by 4 in order to find the width.

w = 12 m

-Hope this helps!

Cameron got 18 out of 20 problems correct on the test.What percent did she make

Answers

She got 90% correct. How? Do 18 divided by 20. You get 0.9 which is equal to 90%

She got 90% because you multiply 18 and 20 by 5 and it equals to 90/100. So, 90% is an A.

You earn $8.50 an hour you work 32 hours a week your deductions are FICA 7.65% federal tax withholding 10.6% and state tax withholding 8.25% how much do you have direct deposited by week

Answers

Firs, we are going to calculate how much you earn per week prior deductions. We know from our problem that you earn $8.50 an hour you work 32 hours a week, so your income per week will be the multiplication of number of worked hours by the amount you earn per hour:
($8.50)(32)=$272

Next, we are going to calculate the total percentage of your mandatory deductions; to do it we are going to add the FICA, federal tax withholding, and state tax withholding percentages:
Total deduction=7.65% + 10.6% + 8.25% = 26.5%

Next, we are going to multiply your weekly income by the percentage of your total deductions to find how much of your weekly income is deduced:
($272)(26.5%)=$72.08

Finally, to find the actual value of your weekly direct deposit, we are going to subtract your deductions from your weekly income:
$272 - $72.08 = $199.92

We can conclude that you will have $199.92 deposited each week.
