Maya bought 6 CDs that were each the same price. Including sales tax, she paid a total of $97.20. Of that total, $5.40 was tax. What was the price of each CD before tax?

Answers

Answer:

Each CD was $15.30.

Step-by-step explanation:

97.20-5.40= 91.80 => 91.80/6=  15.30

Answer: 17.20

Step-by-step explanation:

So 6 x 16 = 96 Then I added 1 dollar and 20 cents to get it to $97.20. so the answer would most likely be 17.20 for each CD.. Sorry for any mistakes! Hope it helped and have a wonderful day! :))

A piece of paper is folded into a certain number of sections (either halves, thirds, fourths, etc) multiple times. The area, A, of the piece of paper in square inches, after n folds, is A = 90 (⅓)n.

What do the 90 and the ⅓ from the equation tell you about the piece of paper or how it was folded?

Answers

Answer:I would say halves maybe But i dont know

Step-by-step explanation:

90 represents the area of the piece of paper before being folded and 1/3 represents paper folded thirds n times.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, the area, A, of the piece of paper in square inches, after n folds, is A = 90 (⅓)ⁿ.

Here, substitute n=0 in the equation, we get

A = 90 (⅓)⁰

A = 90×1

A = 90 square inches

This means the area of the piece of paper before being folded is 90 square inches.

Therefore, 90 represents the area of the piece of paper before being folded and 1/3 represents paper folded thirds n times.

Answer:

Third option.

Step-by-step explanation:

This is matrix addition, so we have to add the corresponding parts of the matrix correctly. The first would be 12+(-3), getting 9. The second part would be (-5)+(-9), getting up -14. Third would be 0+(-14), getting -14. Last would be (-7)+10, getting 3. So, the option with all of the correct parts in their respective positions would have to be the third option.

Jamal says that the fraction 3/4 equals 4÷3. Is he correct?

Answers

Answer:

No

Step-by-step explanation:

If you know fractions, the dividend is the numerator, for example 4 would be the numerator for 4 divided by 3, and the divisor would be the denominator, which for 4 divded by 3 would be 3. Therefore, 4 divided by 3 is equal to 4/3, not 3/4.

Jamal is wrong the value of the fraction 3/4 is not equal to 4÷3.

What is an expression?

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
