The ratio of the measures of the sides of a triangle is 7:9:12, and it's perimeter is 84 inches. Find the measures of each side of the triangle.

Step-by-step explanation:

The lengths of the sides are 7x, 9x, and 12x.

7x + 9x + 12x = 84

28x = 84

x = 3 in

Sides: 21 in, 27 in, 36 in

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
