y²=15²+11.25²

y²=225+126.5625

y²=351.5625

y=18.75

for x:

7.5²=6²+x²

x²=7.5²-6²

x²= 56.25-36

x²=20.25

x=4.5

Answer:

12.8 servings

Step-by-step explanation:

$1\frac{1}{4}$ cups of milk is used to make 10 servings of a recipe.

If $1\frac{1}{4}$ cups or $\frac{5}{4}$ cups of milk is used to to make 1 serving.

Then 1 cup of milk will be required to make servings = $\frac{1}{\frac{5}{4}}$

= $\frac{4}{5}$

Since, 1 gallon = 16 cups

Therefore, 16 cups of milk will be required for servings = $\frac{4}{5}\times 16$

= 12.8 servings
