Answer:

D Multiplying by 3/4 is the same as multiplying by 75%.

Step-by-step explanation:

Lets look at the fraction 3/4.  Multiply by 25/25

3/4 * 25/25 = 75/100

Now we need to change it to a decimal

75/100 = .75

3/4 and .75 are the same.

75 % means out of 100

75 % = 75/100

AC if TC = 20q + 10q^2?
Alexus [3.1K]

Answer:

AC = (20+ 10q)

Step-by-step explanation:

Given that,

Total cost, TC = 20q + 10q²

We need to find AC i.e. average cost.

It can be solved as follows :

AC=\dfrac{TC}{q}\\\\AC=\dfrac{20q + 10q^2}{q}\\\\AC=\dfrac{q(20+ 10q)}{q}\\\\AC={(20+ 10q)}

So, the value of AC is (20+ 10q).

And an 11 ounce bag of rice noodles makes 10 servings at that rate find how many ounces of noodles I needed for 19 servings to t
nikdorinn [45]

Answer:

20.9 ounces of rice noodles are required to make 19 servings.                    

Step-by-step explanation:

We are given the following in the question:

11 ounce bag = 10 servings

Ration of ounces of rice noodles to servings is:

\dfrac{\text{Weight of rice noodles}}{\text{Serivings}} = \dfrac{11}{10} = 1.1

We have to find ounces of noodles are needed for 19 servings.

Thus, we can write:

\dfrac{\text{Weight of rice noodles}}{19} = 1.1\\\\\Rightarrow \text{Weight of rice noodles} = 1.1\times 19\\\Rightarrow \text{Weight of rice noodles} =20.9\text{ ounces}

Thus, 20.9 ounces of rice noodles are required to make 19 servings.
