Answer:

No

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.

Answers

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.

C. Container B will hold the same volume of popcorn as Container A.
D. Container B will hold 1/3 times the volume of popcorn of Container A.

Find angle FCB
sorry that its dark..

Answers

143 degrees (angles on a straight line)
First you need to find variable g. We know that 53+g=90. So g=37

Next, we know that angle FCA is congruent to angle g.

To find angle FCB, you take 180-37=143.
The reason for this is we know line AB is a straight line so it equals 180 degrees.

FCB=143
