Answer:

66,667

Step-by-step explanation:

We are given this chart to complete.

0            _______      ________   40,000          _______      _______

0%             20%            40%             60%                80%            100%

We see that 60% corresponds to 40,000. That means that since 20% is 1/3 of 60%, then the number corresponding to 20% is 1/3 of 40,000.

40,000/3 = 13,333

40% is twice 20%, so corresponding to 40%, you must have 2 × 13,333.

For 40%, you write 26,667.

80% is 4 times 20%, so for 80%, you write 4 × 13,333 = 53,333.

Finally, 100% is 5 times 20%, so for 100%, you write 5 × 13,333 = 66,667.

Answer:

I'm pretty positive it's (-4,-2)

Step-by-step explanation:

i looked at the grid

Step-by-step explanation:

1 week = 7 days of 24 hours each = 7×24 = 168 hours.

the first team can do 1/700 of the total work per hour.

the second team can do 1/600 if the total work per hour.

if they work together, then 1/700 + 1/600 of the total work can be done per hour.

to add these 2 fractions we need to bring them to the same denominator. and that would be 4200 (LCM of 700 and 600).

1/700 + 1/600 = 6/4200 + 7/4200 = 13/4200

so, together, they can do 13/4200 if the total job in 1 hour.

how many hours will they need together to finish the job ?

well, how often does 13 fit into 4200 (as 4200/4200 is the complete job) ?

4200 / 13 = 323.0769231... hours

so, it will still take a little bit over 323 hours to clean all the streets.

but there are only 168 hours until the film crew starts.

so, no, there is not enough time.

To the nearest penny, c = $6,252.50

Total of payments = amount financed + c = $26,752.50

Total of payments ÷ number of payments = monthly payment = $445.88

Answer:

8h > 154.

Step-by-step explanation:

Samantha makes $8 an hour, meaning that the total amount she makes is dependent on the amount of hours she works.

The MP3 player that she wants to purchase is $154, meaning that she will have to get at least $154 or more.

Technically, this means that your answer is:

8h ≥ 154, but because this is not a answer choice, A) 8h > 154 is your best answer, as the amount that she works (in which she is paid $8 each hour), needs to be greater then the amount she needs to purchase the MP3.

Answer:

$0.17 per cup

Step-by-step explanation:

Set up a proportion

$34 / 200 cups = $x / 1 cup

It is 1 cup because it asks how much each cup costs, each = 1.
Cross multiply

34 = 200x

Divide both sides by 200

x = 0.17

Answer:

C, 1 : 16

Step-by-step explanation:

Small Circle

The radius is half of the diameter. 3 inches.

π×r²=A

We'll use 3.14 for pi.

3.14×9

28.26 in²

Bigger Circle

6×4= 24

So the diameter is 24. The radius is 12.

3.14×12²

3.14×144

452.16 in²

Let's divide.

452.16÷ 28.26

= 16

Therefore, the answer is C, 1 : 16.

Answer:

[tex]1.024 * 10^{12}[/tex]

Step-by-step explanation:

[tex]1,024,000,000,000[/tex] = [tex]1.024 * 10^{12}[/tex]

Supplementary angles - Sum = 180°

X + Y = 180°

x = larger angle

y = smaller angle

x = 2y - 60

x + y = 180

x = 180 - y

2y - 60 = 180 - y

2y - 60 -180 + y

3y = 240

y = 80°

x+y = 180

x+80° = 180°

x = 100°

Answer:

middle brother = x

older brother = x+1

younger brother = x-1

x-1+x+x+1=129

3x+0=129

3x=129

x = 43(middle brother)

43-1 = 42(younger brother)

43+1 = 44(elder brother)

Check:

43-1+43+43+1=129

42+43+44=129

129=129

Answer:

Step-by-step explanation:

The reflection across the line y = x gives A'(6, -2), B'(3, -3), C'(-1, 1) and D'(5, 2)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

If a point A(x, y) is reflected along the line y = x, the new point would be at A'(y, x)

The vertex of the quadrilateral is at A(-2, 6), B(-3, 3), C(1, -1) and D(2, 5). The reflection across the line y = x gives A'(6, -2), B'(3, -3), C'(-1, 1) and D'(5, 2)

Answer:

f(g(x))= 3x+9

Step-by-step explanation:

f(g(x)) means that you need to take the function g and plug that function into f for x. So g(x) which is x+4 will be plugged into f(x)=3x-3.

So what you get is 3(x+4)-3

If you distribute the positive three, you will get 3x+12-3 and your answer will be 3x+9.

f(g(x)) can also be written as (fog)(x)

fog just means f composite g or f of g of x

For g(f(x)), it will be the same concept as above. However, this time you will be plugging in f(x) into g(x) and I will let you do g(f(x))
