Marcus is making homemade barbecue sauce. The recipe calls for 3 cups of ketchup for every 1/2 cup of mustard. What is the rate
Yuki888 [10]

Answer: 6 cups of ketchup per cup of mustard

Step-by-step explanation:

Given : The recipe calls for 3 cups of ketchup for every \dfrac12 cup of mustard.

That means , for \dfrac12 cup of mustard. we need 3 cups of ketchup.

By using proportions, if we multiply 2 on both sides ,we get

for  \dfrac12\times 2 cup of mustard. we need 3\times 2 cups of ketchup.

⇒ for  1 cup of mustard. we need 6 cups of ketchup.

Hence, the required rate = 6 cups of ketchup per cup of mustard

Answer:

Yes

sum of angle = 180°

First diagram

R+D+E=180°

110°+28°+E=180°

138°+E=180°

E=180°-138°

E=42°

Second diagram

T+V+A=180°

T+28°+42°=180°

T+70°=180°

T=180°-70°

T=110°
