Answer:

$819

Step-by-step explanation:

First we find the area of the wall so we multiply 13ft x 9ft.

13ft x 9ft = 117ft

We know each square foot is equal to $7. So now we multiply 117 x 7 to get the total cost.

117 x 7 = $819

Answer:

14

Step-by-step explanation:

5x + 2 + 48 = (180-120)+30 +30

5x+50 = 60+30+30

5x+50=120

5x=120-50

5x = 70

x = 70/5

x = 14

Answer:

i don't know ok but today is my math exam

Answer:

Step-by-step explanation:

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional.  So set up two ratios that are = to each other

On the left

long side small triange / long side large triangle = base small triangle / base large triangle

On the right

hypotenuse/longest leg = hypotenuse / longest leg.

Problem A

Set up the similar Proportion

5/40 = x/20                Cross Multiply

40x = 20*5

40x = 100                   Divide by 40

x = 100/40

x = 2.5

Problem B

Again set up the similar triangle proportion

15/10 = x/2                  Multiply by 2

15*2/10 = x              

3 = x

Answer:

[tex]2x^3-3x+4+\frac{5}{3x-5}[/tex]

Step-by-step explanation:

Use polynomial; long division to divide the two polynomials. Remember to put each polynomial in standard form, or rather organize each polynomial by their degree (exponent). The polynomial with the highest exponent will go first, then each with its varying exponent will suceed.

Answer:

y= -x+2

Step-by-step explanation:

Using the equation, y = mx+b, you know you have to find the slope. Find the slope using two coordinate points, (-2,4) and (0,2).

Subtract 2-4/0+2 - the answer is -1. Your slope is -1 and the y axis is given so the equation is y=-x+2

Answer: D

Step-by-step explanation: 15 : 5 is equivalent to 60 : 20 because you multiply both sides by 4

Answer:

40°

Step-by-step explanation:

Since triangle ABC is identical to triangle A'B'C', it has the same measures of respective sides and angles, and ang A is therefore equal to angle A'.

After rotational transformation, the measure of angle ∠A' = 40°.

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.

For the given situation,

The diagram shows the two triangles.

Triangle ABC is the original triangle and A'B'C' is the triangle obtained after the rotation of -120°.

From the definition, in rotational transformation the size and shape of the figure stays exactly the same. Then the angle measures are also remains the same.

Thus the measure of angle A' is [tex]\angle A' = \angle A = 40[/tex]

Hence we can conclude that after rotational transformation, the measure of angle ∠A' = 40°.

Answer:

([tex]n^{2}[/tex]+4)-3

Step-by-step explanation:

since it says "and four" i think it means it is in parenthesis

Answer:

n^2 + 1

Step-by-step explanation:

Let the unknown number be n.  Then "a number squared and four" is

n^2 + 4, and 3 fewer than this result is

n^2 + 3 - 3, or n^2 + 1
