A company’s profit, P, in dollars, for producingx machines in one day is given by P = 500x - 20x*2.If the company produces 10 ma

Slav-nsk [51]

The profit of that day is (C) P = $3,000.

<h3>What is profit?</h3>

A profit is a difference between the revenue generated by an economic entity's outputs and the opportunity costs of its inputs.
Total revenue minus total cost, including both explicit and implicit costs, equals total revenue.
Unlike accounting profit, it only refers to the explicit costs that appear on a company's financial statements.
Accounting profit is calculated by subtracting the firm's total revenue from only the firm's explicit costs.
When analyzing a firm, an economist considers all opportunity costs, both explicit and implicit.

To find the profit of that day:

Given:

P = 500x − 20x², where 'x' is the number of machines per day produced.
If the company produces 10 machines in one day, that is x = 10.

By substituting x = 10 in the above equation, we get:

P = 500 × 10 - 20 × 10²
P = 5000 - 2000
P = 3,000/

Therefore, the profit of that day is (C) P = $3,000.

Solve the compound inequality n-4 > 5 AND 2 > n + 3

Papessa [141]

Get n by itself in both inequalities

(This program doesn't allow for regular less than or greater than signs, so for the purposes of this problem I will be using less than or equal to (≤) and greater than or equal to (≥) signs)

Inequality 1:
$n-4 \geq 5 \\ n \geq 9$

Inequality 2:
$2 \geq n+3 \\ -1 \geq n$

Now that you have both of the n's by themselves, you can put the two inequalities together, like this
$-1 \geq n \geq 9$

Just keep in mind that these are supposed to be regular less than signs

Find the distance between (2,3) and (5,8)

Orlov [11]

Use pythagorean theorem
a^2+b^2=c^2

first find the difference of between the 2 points to find the legnth of the legs

distance between 2 and 5=3
distance between 3 and 8=5 so

3^2+5^2=c^2
9+25=c^2
34=c^2
√34=c

the ligit formula is
$c= \sqrt{(x1-x2)^2+(y1-y2)^2}$

Sydney read 50 pages in 40 minutes. She reads at a constant rate.How many pages can Sydney read per minute?

7nadin3 [17]

Here we are given how much work is done in a fix time interval

then they ask to find the rate of doing the work .

in such problem we can find the rate of doing a work by using the formula :

amount of work done

--------------------------------------------------- = work done in unit time

Time taken to do that amount of work

In 40 minutes number of pages she reads = 50

In 1 minutes number of pages she would be reading = 50 /40

= 5/4 page

Answer 5/4 page .
