A company sells each product they make for $84.00. They pay $2,100.00 in monthly costs such as rent and bills as well as $70.00
mel-nik [20]

Answer:

P=14x-2100

Step-by-step explanation:

<em>Since equations are not listed, i will simply figure out the correct answer.</em>

<em />

Profit is Income MINUS Cost.

The cost is a fixed cost of 2,100 per month.

Also a variable cost of 70 per unit (x), if x units sold, then variable cost would be "70x"

Total Cost = 2100 + 70x

Now, the income is from sales of each unit. Each unit sells for $84 and if x units sold, company's income would be:

84x

So, profit will be:

Profit = Income - Cost

Profit = 84x - (2100 + 70x)

Profit = 84x - 2100 - 70x

Profit = 14x - 2100

We can write the equation as:

P=14x-2100

Alex is feeling stressed this morning. He did not get enough sleep because a dog barked most of the night. The dog barked from 1
inna [77]

Answer:

Poor Alex, I know how they feel, I got a dog myself.

The amount of time between

11:41 pm to 12:09 am is

19 minutes (to 12 am, 60 minutes to next hour) + 9

which is 28 minutes for the first dog barking session

the second time is 35 minutes,

using same method as before.

adding the two separte barking sessions we get

35+28= 63 minutes

which is equivelant to 1 hour and 3 minutes.

In conclusion the dog barks for 1 hour and 3 minutes in total.

11.)-If PQRS is a parallelogram, find the values of x and y.
defon

Step-by-step explanation:

For no. 11

13x + 15 = 19x - 9 ( being opposite sides of parallelogram)

19x - 13x = 15 + 9

6x = 24

x = 4

Also,

4y + 7 ° + 10y - 37° = 180° { being co-interior angles }

14y - 30° = 180°

14y = 210°

y = 210° / 14

y = 15°

For no. 12

5x + 38° = 8x - 19° { being opposite angles of parallelogram }

8x - 5x = 38° + 19°

3x = 57°

x = 19°

Hope it will help :)
