First, you would need to create an equation for this problem.
\frac{4}{5} = \frac{x}{2,000}

Next, you would cross multiply. 
5x = 8,000

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 5. 
x = <span>1,600

1,600 people are considered middle class. 

I hope this helps!</span>

A company sells its product for $59 per unit. Write an expression for the amount of money received (revenue R) from the sale of
zaharov [31]

Answer:

R = 59x

Step-by-step explanation:

We are given the following in the question:

Cost per unit = $59

Let x units of product be sold.

We have to write an expression the amount of money received (revenue R) from the sale of x units of the product.

Revenue:

  • It is the total income  and is obtained by multiplying the quantity of goods sold by the unit price of the goods.

Revenue =

\text{Unit Cost}\times \text{Units sold}\\R = 59x

is the required expression of revenue.

NO LINKS!! Find the indicated measure for each circle shown. Round answers to the nearest tenth. ​

Problem 13

x = central angle = 360-105 = 255 degrees

r = 8 = radius

A = sector area

A = (x/360)*pi*r^2

A = (255/360)*pi*8^2

A = 142.41887

I used the calculator's stored value of pi to get the most accuracy possible.

Round that decimal value however you need to. The same applies to the other questions as well.

<h3>Answer: Approximately 142.41887 square inches</h3>

========================================================

Problem 14

x = central angle = 114 degrees

r = radius = unknown

A = sector area = 36 square cm

A = (x/360)*pi*r^2

36 = (114/360)*pi*r^2

36*(360/114) = pi*r^2

113.68421 = pi*r^2

r^2 = 113.68421/pi

r^2 = 36.18681

r = sqrt(36.18681)

r = 6.015547

<h3>Answer: Approximately 6.015547 cm</h3>

========================================================

Problem 15

x = area of the full circle

The pizza slice shown has an area of 49 square meters.

This is 68/360 of a full circle, which means,

sector area = (68/360)*(full circle area)

49 = (68/360)*x

x = 49*(360/68)

x = 259.41176

<h3>Answer: Approximately 259.41176 square meters</h3>
