Answer:

Sean earns $7.5 in each hour.

Step-by-step explanation:

Given:

Money earned by Sean = $300

Number of hours worked in a day = 8 hrs

Number of days of work  in a week = 5

We need to find Money earned in each hour.

First we will find Total hours work in a week.

Total hours work in a week is equal to Number of hours worked in a day multiplied by number of days work in a week.

Framing in equation form we get;

Total hours worked in a week = 8\times5 = 40\ hrs

Now we will find money earned for each hour.

Money earned each hour will be calculated by Dividing Total Money earned in a week by Total number of hours worked in a week.

Framing in equation form we get;

Money earned each hour = \frac{300}{40} = \$7.5

Hence Sean earns $7.5 in each hour.

Given the cost function, C(x), and the revenue function, R(x), find the number of units x that must be sold to break even C(x)=1
natka813 [3]
Consider these specific values of x.

For example, if x=10, then <span>C(10)=16(10)+36,000=160+36,000=36,160 (say $)

 and R(10)=18*10=180.


So if only 10 units are produced, the total cost is 36,160, while the revenue is only 180 (again, say $.)



If, for example, x=1000, then we can calculate 

</span><span>C(1000)=16*1000+36,000=16,000+36,000=52,000

and 

R(1000)=18*1000=18,000.


This suggests that with higher values of x, we can get to a particular point where the Cost and Revenue are the same. To find this point, we set the equation:
                            C(x)=R(x), 

which gives us that particular x at which both </span>C(x) and R(x) give the same value.

Thus, we solve <span>16x+36,000=18x. Subtracting 16x from both sides                                                         2x=36,000,   then x = 36,000/2=18,000.


 
Answer: 18,000

Two similar triangles have have areas of 75 m2 and 12 m2. find the ratio of the perimeters
soldi70 [24.7K]

we know that having similar triangles so the ratio of sides,area and volume are same.

s/s=s^2/s^2

we know that s^2 will be the area of triangle.

s^2/s^2=75/12

so s/s=\sqrt{75/12}

so the ratio of the perimeter of two triangles will be

(s+s+s)/(s+s+s)=(\sqrt{75} +\sqrt{75} +\sqrt{75} )/(\sqrt{12}+\sqrt{12} +\sqrt{12} )

ratio of the perimeter=\sqrt{225} /\sqrt{36}

Answer:

A. x > -3

Step-by-step explanation:

Well by looking at the graph we can tell that,

the line we can tell that the line goes to the right of of the number line,

Meaning x is greater than -3.

<em>Thus,</em>

<em>x > -3.</em>

A 10 ft fence is 8 in .long on the scale drawing. What is the scale drawing?
lions [1.4K]
To find scale we have to provide common unit, so inches.
10 foot = 120 inch becauyse 1 foot = 12 inch so 
10foot*12=120 ich
Now
8 inch in drawing is 120 in real, so the scale is 8:120
