Let's call the number of members x. We have x + 10 people who each pay $5, resulting in a sum of $600.

5(x+10) = 600

5x + 50 = 600

5x = 550

x = 110

Answer:

8.65%

Step-by-step explanation:

We have been given that Debra earns $4740 per month. Every month she saves $410. Additionally, she has $2520 in outstanding credit cards and makes a $210 monthly payment of these cards.

$\text{Savings ratio}=\frac{\text{Savings}}{\text{Income}}\times 100\%$

Upon substituting our given values in above formula, we will get:

$\text{Savings ratio}=\frac{410}{4740}\times 100\%$

$\text{Savings ratio}=0.08649789\times 100\%$

$\text{Savings ratio}=8.649789\%$

$\text{Savings ratio}\approx 8.65\%$

Therefore, Debra's approximate savings ratio is 8.65%.

I need help somebody please

Her pay increases $10.00 fore every hour she works

The slope of the line is 10 because you have to pick two points off of the graph, it doesn't matter what two points, and stick them in the formula: y²-y÷x²-x. Once you work out this formula, you get 10/1 which equals to the slope being 10.

PLEASE HELP!!!!!!!! FIRST TO ANSWER WILL GET BRAINLIEST!!!

If you are not familiar with the Pythagorean theorem, I will write it below to remind you for your future mathmatical endeavours:

${a}^{2} + {b}^{2} = {c}^{2}$

c is the hypotenuse, and a and b are the other two sides. The hypotenuse is the largest side of a triangle. In this example, a and b are equal to each other and c is equal to 2, so I'm going to convert b into a and do some math trickery here:

${a}^{2} + {a}^{2} = 4$

$2 {a}^{2} = 4$

Basically, I swapped b with a and combined like terms. Then I just replaced c with 2, then squared it into 4.

All you have to do now is solve for a

Step 1 is to divide both sides by 2 to get:

${a}^{2} = 2$

Then just square both sides:

$a = \sqrt{2}$

Now you know that the length of the sides are equal to the square root of 2.

Sorry if this was a bit rushed, I hate running out of time on these. If you have any questions on why I did something, ask away in the comments.
