n/12 = 3/4


A. n = 12
B. n = 15
C. n = 18
D. n = 9

Answers

Answer 1

Answer:D. n = 9

Step-by-step explanation:

n/12 = 3/4 // - 3/4

n/12-3/4 = 0

1/12*n-3/4 = 0 // + 3/4

1/12*n = 3/4 // : 1/12

n = 3/4/1/12

n = 9

Dana and Monique are dog groomers. Dana's workday is 10 hours and Monique's workday is 8 hours. Dana and Monique each work 40 hours per week. On Monday, Dana groomed 15 dogs in 10 hours and Monique groomed 10 dogs in 8 hours. They each earn $12.75 for each dog groomed.

Answers

Answer:

$127.50

Step-by-step explanation:

On Monday Dana earned: 15*12.75 in 10 hours

For 40 hours Dana will earn: 15*12.75*(40/10) = $765

On Monday Monique earned: 10*12.75

For 40 hours Monique will earn: 10*12.75*(40/8) = $637.50

The difference between the weekly earnings is: $765 - $637.50 = $127.50.

What value of w makes this multiplication sentence true? 28 · (824 + 514) = 28 · 824 + 28 · w

w =

Answers

Answer:

514

Step-by-step explanation:

First, we need to find the value of the non-variable side.

824+514 =1,338.

1,338 multiplied by 28 is 37,464.

So now we have :  37, 464 = 28* 824 + 28* w

28* 824 is 23,072.

And then we have, 23,072 * 28w.

Subtract 37,464 by 23,072on both sides, which is equal to 14,392 = 28w

Finally, divide 14,392 by 28 on both sides to get 514 = w

Therefore, w is 514.

Good luck mate, hope this helps.

Answer:514

Step-by-step explanation:

1338 x 28 = 37464

28 x 824 = 23072

37464 - 23072 = 14392

28 x 514 = 14392

Examine the table below. The table shows the cost to order pizzas at a local pizza shop. Determine how much it would cost to order 5 pizzas.

Pizza(n) 3 6 9 12 15
Cost (C) $9.99 $19.98 $29.97 $39.96 $48.95

Answers

It would cost $16.65

$9.99 divided by 3 is 3.33 so we know one pizza costs $3.33. So now if I multiply the 5 pizzas times the cost of one I get 5 x $3.33 = $16.65
it would cost $16.65
9.99 divided by 3 = 3.33
3.33 x 5 = 16.65

The question is: Find the interest rate on a $895 dollar investment with $716 in interest over 5 years. Show your work.

Answers

Answer: The interest rate on the $895 investment is approximately 16%.

Step-by-step explanation:

To find the interest rate, we can use the formula for simple interest:

Interest = Principal × Rate × Time

Given:

Principal (initial investment) = $895

Interest earned = $716

Time period = 5 years

We rearrange the formula to solve for the rate:

Rate = Interest / (Principal × Time)

Substituting the given values:

Rate = $716 / ($895 × 5)

Now, let's calculate the values:

Rate = $716 / $4475

Rate ≈ 0.1599

To convert the decimal to a percentage, we multiply by 100:

Rate ≈ 0.1599 × 100

Rate ≈ 15.99%

Therefore, the interest rate on the $895 investment is approximately 15.99% or rounded to 16%.

This means that for the $895 investment, an annual interest of $716 has been earned over a period of 5 years. It indicates that the investment has grown by an average of 16% per year.

When executing these plays, every individual must work together in a specific role; this teaches children how to work together. Since sports are based on competition, participants also learn how to lose gracefully and develop a sense of fair play.
