A recipe calls for 1 1/2 gallons of chopped onions.How many pounds of onions should you use if one cup of chopped onions weigh 6

Dvinal [7]

Answer:

15 pounds of onions are needed in the recipe.

Step-by-step explanation:

Total gallon of chopped onion needed for the recipe = 1 1/2 gallons

Solving the mixed fraction, we get

$1\frac{1}{2} = 1 + \frac{1}{2} = 1 + 0.5 = 1.5$

So, the chopped onion needed = 1.5 gallons

Also, 1 gallon = 160 ounces

So, 1.5 gallon = 1.5 x (160) ounces = 240 ounces

⇒ 1.5 gallon = 240 ounces

Now, 1 ounce = 0.0625 pounds

⇒ 240 ounces = 240 x 0.0625 pounds = 15 pounds

Hence, 15 pounds of onions are needed in the recipe.

Given O A ‾ ⊥ O C ‾ OA ⊥ OC start overline, O, A, end overline, \perp, start overline, O, C, end overline m ∠ B O C = 6 x − 6 ∘

Lelu [443]

Answer:

m∠BOC = 40°

Step-by-step explanation:

Given O A ‾ ⊥ O C ‾ OA ⊥ OC m∠BOC=6x−6 ∘

m∠AOB=5x+8 ∘

Find m ∠ B O C:

This means that: m∠BOC and m∠AOC intersect at a right angle.

Hence:

m∠BOC + m∠AOC = 90°

Step 1

Solving for x

6x - 6 + 5x + 8 = 90°

11x -2 = 90°

11x = 90 - 2

11x = 88

x = 88/11

x = 8

Step 2

Solving for m∠BOC

m∠BOC = 6x - 8

m∠BOC = 6(8) - 8

= 48 - 8

= 40°
