Answer: y=10.50x+420

Step-by-step explanation:

If you take

y=10.50x+420

and you plugin 2 for 2 weeks of work, you will get the total amount that she has after 2 weeks of work

y=10.50(2)+420

y=21+420

y=441

y=10.50x+420

Answer:

28 feet

Step-by-step explanation:

Since each side length of the square is 1 foot.

Let x represent the length of the small slant side and y represent the length of the long slant side. Hence:

x² = 5² + 1²

x² = 26

x = √26 = 5.1 feet

y² = 6² + 3²

y² = 45

y = 6.7 feet

The perimeter of the figure is the sum of all the sides of the figure, hence:

Perimeter = 11 feet + 4 feet + 5.1 feet + 6.7 feet + 2 feet = 28.8 feet

Therefore the best estimate of the perimeter of the figure below is 28 feet.

Answer:

Area of the sector = [tex]\frac{\pi }{8}[/tex] cm²

Step-by-step explanation:

Measure of the given arc = 45°

Central angle formed by the arc = 45°

Formula to be used,

Area of the sector bounded by the arc = [tex]\frac{\text{Central angle}}{360}\times \pi r^{2}[/tex]

Here, r = radius of the circle

Area of the sector = [tex]\frac{45}{360}(\pi)(1)^2[/tex]

                               = [tex]\frac{\pi }{8}[/tex] cm²

Answer:

Δy = 9

Δx = -6

Slope = -3/2

Step-by-step explanation:

The slope formula is the change in y (Δy) over change in x (Δx).

Δy = [tex]y_2-y_1[/tex]

Δx = [tex]x_2-x_1[/tex]

We are given the points of (5,-3) and (-1,6).

[tex]m=\frac{6-(-3)}{-1-5}=\frac{9}{-6}=\boxed{-\frac{3}{2}}[/tex]

The slope is -3/2.

Hope this helps.

Answer:

1. $48

2.$49

3.$91

4.$12

Step-by-step explanation:

For 1 and 2

To find the sale price, you find out how much is the percentage of the original price. Example :

(20/100)/60 = $12

So $12 is the discount

thus sales price will be $60-$12=$48

Same thing for no.2, find the amount of the percentage and subtract it from the original price

For 3 and 4

To find the original price

1. Subtract the percentage from 100%

2. Multiply the sales price by 100

3. Divide the ans from no.2 by ans from no.1

Example :

100%-40%=60%

$54.60×100=5460

$5460÷60%= $91 (original price)

Same thing for no.4

Hope this helps haha

Answer:

{-7, 2, 8}

Step-by-step explanation:

We see that the domain is limited to three x-values: -3, 0 and 2. To find the range (which is the set of all y-values) we just need to plug-in these x-values and find the corresponding y-values.

So our equation is:

y = 3x + 2

Then we substitute for the x-values:

y = 3(-3) + 2

y = -9 + 2

y = -7

y = 3(0) + 2

y = 0 + 2

y = 2

y = 3(2) + 2

y = 6 + 2

y = 8

So our range would be {-7, 2, 8}.

Answer:

640 units squared

Step-by-step explanation:

The shape below is a trapezoid.

The formula for the  area of a trapezoid is average of the bases times the height.

The bases are the parallel lines that make up 2 of the sides of the trapezoid.

The height is the line dotted line that creates right angles and is the distance between the two bases.

The bases are 24 and 40.

To find the average, we add them together and divide by 2

(24+40)/2=64/2=32

Now, we multiply 32 by the height, which is given as the length of 20.

32*20=640

the area of the trapezoid is 640 units squared

Answer:false

Step-by-step explanation:

The radius of the circle is 17 feet. Then the area of the circle is 907.46 square feet.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let r be the radius of the circle. Then the area of the circle will be given as,

A = πr² square units

The diameter of the circle is 34 feet. Then the radius of the circle is calculated as,

r = 34 / 2

d = 17 feet

The area of the circle is calculated as,

A = πr²

A = 3.14 x 17 x 17

A = 907.46 square feet

Answer:

to find the long side ( hypotneuse) you use the equation a^2+b^2=c^2 where c^2 is the hypotneuse. In this case 7^2 + 6^2=c^2

49+36=c^2

85=c^2

take the square root of 85 to get c
