How can models help you rename a mixed number as an improper fraction or a improper fraction as a mixed number?

Mixed numbers and whole numbers use circle graphs to emphasize them. For example a mixed number would be 1 whole circle and 1/2 or 3/4 of another. An improper fraction would be 4 circles and each divided into 100 to make 400/4 then you can simplify it to make an exact 100. Hope I helped. PS I didn't ever have this question.

Answer:

56°

Step-by-step explanation:

hii!

to solve this, we need to know that the angles of a triangle all add up to 180 degrees.

we are going to make an x equation here.

2x+3x+40=180

5x+40=180

    -40  -40

5x=140

/5   /5

x=28

angle a is 2x, so the answer would be 28*2 which is 56°

hope this helped out :)

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).
