Answer:

Orange, Blue, Red, Green.

Orange would be the best deal.

Step-by-step explanation:

In order to put the unit costs per square foot from least to greatest, let's find the unit cost per square root of each wrapping paper.

To find the unit cost per square root, we simply have to divide the cost over the amount of square feet. So:

Red:

c=\frac{1.79}{12.5}=\$0.1432\text{ per square foot}

Blue:

c=\frac{5.29}{40}=\$0.13225\text{ per square foot}

Green:

c=\frac{8.49}{50}=\$0.1698\text{ per square foot}

Orange:

c=\frac{6}{60}=\$0.10\text{ per square foot}

So, to cost of wrapping paper per foot from least to greatest is:

Orange, Blue, Red, Green.

So, orange would be the best deal.

And we're done!

Use the tests for divisibility to determine which numbers divide evenly into the given number.
drek231 [11]

The numbers that can divide 648 evenly, using the divisibility tests, include <u>1, 2, 3, 4, 6, 8, 9, 12, and 18</u> and some multiples of any two numbers.

<h3>What is the divisibility test?</h3>

A divisibility test is performed to identify whether a number can be divided evenly by a fixed divisor without a remainder and without actually performing the division process.

<u>Divisibility by 1</u>: Every number is divisible by 1 = 648 (648/1).

<u>Divisibility by 2</u>: 648 is an even number and divisible by 2 = 324.

<u>Divisibility by 3</u>: Sum the digits (18). 18 is divisible by 3 = 6 (18/3).

<u>Divisibility by 4</u>: The last two digits (4 and 8) form a number (12) that is divisible by 4

<u>Divisibility by 6</u>:  It is divisible by 2 and by 3

<u>Divisibility by 8</u>: If the hundreds digit is even, the number formed by the last two digits must be divisible by 8.

<u>Divisibility by 9</u>: Sum the digits (18). 18 is divisible by 9

<u>Divisibility by 12</u>: 648 is divisible by 3 and by 4.

<u>Divisibility by 18</u>: 648 is divisible by 2 and by 9.
