Answer: For 20 hours it would be $1,500 and for 50 hours it would be $3,000.

Step-by-step explanation:

The equation for this problem would be y=50x+500.

Y is the total charge and x is the amount of hours. Plug in 20 and 50, and then you have your answer.

Answer:

Joe makes 5 dollars a week

Step-by-step explanation:

Joe started with 173 so you will subtract that from the total

208-173=35

You will then divide that number by the number of weeks he has worked

35÷7=5

Therefore joe makes 5 dollars a week

The amount of money that he earns each week will be $5 per week.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Joe has $173 he earns the same amount of money each week for seven weeks and put this money in the bank now Joe has $208 in the bank.

Let 'm' be the amount of money that he earns each week. Then the equation is written as,

208 = 7m + 173

Simplify the equation, then we have

208 = 7m + 173

35 = 7m

m = $5

The amount of money that he earns each week will be $5 per week.

Answer:

a = 60°

60°, 60°, 120°, and 120°.

Step-by-step explanation:

Sum of interior angles of a quadrilateral = 360°

Therefore:

a° + a° + 2a° + 2a° = 360°

Add like terms

6a = 360

Divide both sides by 6

a = 60

2a = 2(60) = 120°.

Angle measure from least to greatest are 60°, 60°, 120°, and 120°.

Step-by-step explanation:

Given data

We are told that the total pounds of garbage is modeled by

f(x) = 50x + 5200

comparing the above expression with the equation of a line

y= mx+c,

we can see that

f(x) represents y, which the total garbage collected in pounds

m is 50 which is the amount of garbage in pounds collected per year

x is the number of years

and 5200 is the already existing garbage in pounds

Answer:

48 °

Step-by-step explanation:

The following data were obtained from the question:

Adjacent = 12 cm

Hypothenus = 18 cm

Angle R =?

We can obtain angle R by using cosine ratio. This can be obtained as follow:

Cos R = Adjacent / Hypothenus

Cos R = 12 / 18

Cos R = 0.6667

Take the inverse of Cos

R = Cos¯¹ 0.6667

R = 48 °

Thus, <QRP = 48 °

109 m

Step-by-step explanation:

189-(15+36+29)=109 meters

Answer:

6.2

Step-by-step explanation:

Although there's multiple ways to solve this problem, my method will be to simply find the area for the full triangle (the empty + orange triangles) and subtract the area of the smaller, empty triangle.

Now, you that area for a triangle is 1/2*base*height.

To find the measurements for the full triangle, you must add up the bases for the two smaller triangles:

[tex]Base_{total} = Base_{empty} + Base_{orange} \\Base_{total} = 1.9ft + 3.1 ft\\Base_{total} = 5 ft[/tex]

Height is the same for both triangles so Height total = 4 ft.

Now the total area can be calculated:

Area total= 1/2* base_total * height_total

Area total = 1/2 * 5ft * 4 ft  

Area total = 20 / 2 = 10 ft squared

Lastly, subtract the area of the empty triangle from the total triangle to find the orange triangle.

Area Empty Triangle = 1/2 * base_empty * height_empty

Area Empty Triangle = 1/2 * 1.9ft * 4 ft = 7.6 ft / 2 = 3.8 ft squared

Area total - Area empty = 10ft^2 - 3.8ft^2 = 6.2 ft squared

Answer:

1400 Calories

Step-by-step explanation:

First we need to find the total Miles ran so we multiply 8 x 1.25

That would be 10.

If she burned 140 calories PER mile, then we multiply the miles by 140

10 x 140 = 1400

Answer: A rotation about 270 degrees CW about the origin and 90 CCW about the orgin.

Step-by-step explanation:  Using the rules of 90 degrees Counterclockwise

(x,y)⇒( -y,x)

D is 3,2 then it  goes to  -2,3 which were A is

E is 3,7 then it goes to -7,3 which C is at

F is 10,5 then it goes to -5,10 where B at.

Also it 270 CW because 270 CW is the same as 90 CCW.
