An art student is trying to determine how many tubes of paint they will need for their mural. if they are using 3 tubes every 4 days, how many tubes would they use in 8 days?

6 tubes

Step-by-step explanation:

Create a simple relationship.

4 days = 3 tubes

8 days = ? tubes

Well, if there is twice as many days, twice as many tubes will be used.

4 days x 2 = 8 days

3 tubes x 2 = 6 tubes

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
