Final answer:

The ratio of students to teachers at San Jacinto Middle School is 264 : 11, which means for every 11 teachers, there are 264 students.

Explanation:

The subject of the question is Mathematics and it pertains to the concept of ratios. Ratios are used to compare two or more numbers. In this context, we are given the total number of students and teachers at San Jacinto Middle School and asked to find the ratio of students to teachers. To calculate this, we divide the number of students by the number of teachers.

Here's how you do it step-by-step: The school has 528 students and 22 teachers. So, the ratio would be 528 : 22. This ratio can be simplified by dividing both numbers by their greatest common divisor, which is 2 in this case. Hence, the simplified ratio is 264 : 11.

So, the ratio of students to teachers at San Jacinto Middle School is 264 : 11. This means for every 11 teachers, there are 264 students.

Step-by-step explanation:

To Clarify a rational number is just a number that can be made into a mixed fraction. Or another way of doing this would be to say a number like 1.50. So currency is a form of rational numbers.

EX: You decided to go to college but as a broke college student you couldn't pay for college (because it is expensive) so you decide to take out a student loan. For simplicity's sake let's say that you only need a $15,236.75 loan to add to the money you had saved up for college. However, the loan agency adds a 0.05 per month interest rate as soon as your 4 years of college are over. Knowing that interest adds up fast you decide to try to pay off as much loan debt as you can while still in college with your part-time job. You end up paying off $746.98 leaving you with only $14,489.77 left of the loan. The first month out of college you wind up with only $15,214.26 of college debt. Before the next month however you marry your college sweetheart and as a couple, you take on each other's debts making your grand sum for college debts $32,416.51. After five blissful years of marriage you wind up getting a divorce but because finances have been jumbled (real-world ish) you decide just to divide the $12,758.36 debt from college evenly between the two of you.

Subtraction:

• 15,236.75-746.98 = 14,489.77

Multiplication:

• 14,489.77x.05 = 15,214.26

Addition:

• 32,416.51 = 15,214.26+17,202.25

Division:

• 12,758.36/2 = 6,379.18

Answer:

A) The cost is the same at 5 months.

Step-by-step explanation:

Lets use m to represent the number of months it will take for the cost to be the same. If we set up an equation, we can write:

75 + 10m = 50 + 15m

-50 on both sides

25 + 10m = 15m

-10m on both sides

25 = 5m

Divide by 5 on both sides.

5 = m

That means it will take 5months for the costs to be the same.

Answer:

41.2 feet of wallpaper

100.8 square feet of carpet

Step-by-step explanation:

The wallpaper is going to be around all the four walls of the bedroom and to know how many feet of wallpaper we know that the bedroom is:

12.6 feet long and 8 feet wide.

So two walls are 12.6 feet and two are 8 feet, so we have to add the total of feet the perimeter of the bedroom is:

12.6+12.6+8+8 = 41.2 feet of wallpaper.

With the carpet, we need to know the area of the room because it will be on the floor. The formula for the area of a rectangle is:

A=L*W

where:

A is area

L is length

W is wide

Now we will substitute the data we have in the formula:

A = 12.6 * 8

A = 100.8 square feet of carpet.
