b. how many cups of olive oil did she use in each batch of salad dressing?

a) 1/16 gallon

b) 1/8 cups

Step-by-step explanation:

Total quantity of olive oil = 1/2 gallon

Total number of salad dressing is 8

a) Total quantity olive oil for 8 identical salad dressing = 1/2 gallon

therefore for each salad dressing she would need gallon olive oil

b) suppose for 1/2 gallon oil one one cup is used

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
