The answer would be C) 2 since 2 can go into both 64 and 18 by multiplication and division.

Let's start by finding all the factors of 64 and 18.

64 / 2 = 32
32 / 2 = 16
16 / 2 = 8
8 / 2 = 4
4 / 2 = 2

This means:
64 = 2 * 2 * 2 * 2 * 2 * 2 = 2^6

18 / 2 = 9
9 / 3 = 3

This means:
18 = 2 * 3 * 3

The only factor that they both have in common is 2, so 2 is the GCF.

The perimeter of a rectangular deck measured 130 m. What are the possible

fomenos

Answer:

The possible dimensions of the deck can be anything that adds up to be 130 m.

Step-by-step explanation:

The perimeter could be 1m x 64m.

Two sides would be 1m each (so 2m total) and the other two sides would be 64m each (128m total). 2 + 128 = 130m.

The perimeter could be 15m x 50m.

Two sides would be 15m each (so 30m total) and the other two sides would be 50m each (100m total). 30 + 100 = 130m.

A merchant buys a television for $125 and sells it for a retail price of $200. What is the markup

beks73 [17]

The markup is the percent of the original price that it is increased by. To determine the percentage marked up, you will subtract the new price and the original price, and then divide that by the original price.

200-125=$75

75/200=0.375 or 37.5% markup.
