Ted is making trail mix for a party. He mixes 1 1/2 cups of nuts, 1/4 cup of raisins, and 1/4 cup of pretzels. How many cups of pretzels does Ted need to make 15 cups of trail mix?

Find the total of everything he is using:

1 1/2 + 1/4 + 1/4 = 2 total cups.

For every two cups of trail mix he uses 1/4 cup of pretzels.

15 cups/ 2 cups = 7.5

7.5 x 1/4 cup of pretzels = 1 7/8 cups of pretzels.

Ted needs 1.875 cups of pretzels to make 15 cups of trail mix

Step-by-step explanation:

He mixes 1 1/2 cups of nuts, 1/4 cup of raisins, and 1/4 cup of pretzels. This means that the ratio of ratio of the number of cups of nuts used to the number of cups of raisins used to the number of cups of pretzels used is

1.5 : 0.25 : 0.25

The total ratio is

1.5 + 0.25 + 0.25 = 2

Ted need to make 15 cups of trail mix. Therefore, the number of cups of pretzels that he needs to use is

0.25/2 × 15 = 1.875 cups of pretzels

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

if x = 1, then the answer is 3.5
