I AM SO CONFUSED! Please Please help but explain the answer! I have been stuck for so long! Larry is planning to install a rectangular pool that is 6 feet shorter than it is wide. Larry wants to find its width if its area is 169 square feet. Which equation models this problem?

So I know that the length must equal W - 6, and that the area is 169. But, I only know how to find the width by dividing the area by the length (W = A/L). But I do not know the length. So I am kinda sorta really stuck. You do not need to solve this problem. I just need to know the equation to solve this problem. THANK YOU SO MUCH!!

Answers

Answer 1

Answer: Area equals length multiplied by width

A = L • W

We know that the length is 6 foot shorter than the width, so it would be:

A = (W – 6) • W

Your equation would be:

169 = (W – 6) • W

6 3/8 as a decimal and percent. HELP..

Answers

First we need to make it a decimal. So we need the denominator to be 10, 100, 1000, 10000 or something along those guidelines. * can't go in 10, 100 but it can go in the thousandths place ( 1000 / 8 = 125 ) So we multiple the top and the bottom of 6 2/8 by 125. our fraction now looks like this 6 375/1000 In a decimal it looks like 6.375. To make it a percent, move the decimal two places to the right. The percent is 637.5% and the decimal is 6.375. Hope that helps!

the answer should be 6.375 I believe.

A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times. Three column table. First column values are Section 1 and 20. Second column values are Section 2 and 36. Third column values are Section 3 and 24.

What is the experimental probability of the arrow stopping over Section 2?

A.

B.

C.

D.

Answers

The answer is very simple.
Just divide 36 by 80.
36/80 = .45
turn .45 into a percent.
There is a %45 chance that it will land on section 2.

The answer is 9/20, or 45%,

You can walk 13434 miles in 1212 hour. What is your average speed?

Answers

To find the speed, distance or time, you follow the pyrimad in the link.

According to the pyrimad, you divide distance by time to get speed. 13434 divided by 1212=11.08 ( 2 decimal places). The speed is therefore 11.08

Annisa wrote an expression the product of 6.2 and the sum of 3c and 8 what are the factors of the expression

Answers

(6.2) and (3c+8) are the factors of the expression.

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, Annisa wrote an expression the product of 6.2 and the sum of 3c and 8

Let us break down and translate the word expression into an algebraic expression.

The sum of 3c and 8 is algebraically represented as:

= 3c + 8

Thus, the product of 6.2 and the sum of 3c and 8 will be algebraically represented as:

= (6.2) (3c + 8)

We know that the numbers that we multiply are the factors of the product.

Hence, (6.2) and (3c+8) are the factors of the expression.
