Step-by-step explanation:

Take the original price and multiply by the discount

180* 20%

180 *.20

36

Subtract this from the original price

180-36 =144

The sale price is 144

Answer:

First answer option:

"The first equation should be multiplied by 2 and the second equation by 3. "

Step-by-step explanation:

The first equation should be multiplied by 2 and the second equation by 3. This way the term in y in the first equation becomes "(2) (-3y) = -6y", and the term in y in the second equation becomes "(3) (2y) = 6y" so when added term by term, the term in "y" disappears.

That is represented by the first statement in your list of possible answers

Answer:

<ABC = 30°

Step-by-step explanation:

<ABC + <CBD = 90 [Complementary angles add up to 90°]

x+7+2x+14 = 90

3x + 21 = 90

3x = 90-21

3x = 69

Dividing both sides by 3

x = 23

Now

<ABC = 23+7

<ABC = 30°

Answer:

30 degrees

Step-by-step explanation:

Answer:

120

Step-by-step explanation:

The sum of the degrees in any quadrilateral is 360. So add up all of the degrees you know and subtract it from 360 to get your answer.

120 + 60 + 60 = 240

360 - 240 = 120

another way you know that's easier is the angles that are diagonal are equal to one another, so since x is diagonal to 120, it is equal to 120.

Answer:

1.797 mm

Step-by-step explanation:

The key to solving this problem is finding the length of the coin wrapper, or "height" of the cylinder.

The volume of a cylinder equation is:

V = hπr^2

- We want to find h

- We are given diameter and we will want the radius so we divide

21.17/2 = 10.585

r = 10.585

So to find h we manipulate the equation by dividing both sides by pi and r^2

resulting in the following:

h = [tex]\frac{V}{\pi r^2}[/tex]

now substitute given values and we get

h = [tex]\frac{28470}{\pi10.585^{2} }[/tex] = 80.883

Now to find the thickness of a single coin we divide the length of the sleeve (h) by the number of coins in the sleeve (45).

Thickness = 80.883/45 = 1.797 mm

Answer:

Scalene

Step-by-step explanation:

Because all of the sides are different lengths

Answer & Step-by-step explanation:

9x² + 6x + 12x + 8

First, simplify the expression.

9x² + 18x + 8

Now that you have simplified the expression, you can start factoring it. First, you have 9x². You can factor into 3x and 3x because 3 times 3 is 9 and once you multiply x by x, you will get x².

(3x + )(3x + )

Now that we have this part of the factoring, we have to find the other part. We can do this by looking at our constant number. Constant meaning a number that does not have a variable beside it. So, in this case, our constant is 8. We can reduce 8 into 2 and 4 because 2 times 4 is 8.

(3x + 2)(3x + 4)

So, the factored form of 9x² + 6x + 12x + 8 is (3x + 2)(3x + 4)

Answer:

The rectangle (A) has the largest area.

Step-by-step explanation:

To work out the area of the rectangle you have to multiply the width with the height.

A: 3 squares tall, and 5 squares wide. We have to multiply 3 with 5 which equals 15.

B: 2 squares tall, and 6 squares wide. We have to multiply 2 with 6 which equals 12.

The highest answer or area is 15. Which is Rectangle A.

[tex]\frac{20}{100} = \frac{1}{5} \\\frac{4}{20} = \frac{1}{5}[/tex]

Answer:

4/20

Step-by-step explanation:

4/20=1/5=20%

Let h= the number of hours the driver drove

Let m= the number of miles driven

25h+2m=625

m=50h

System of equations are 25x + 2y = 625 and y = 50x

Where x represents number of hour of driving and y represent number of mile driven for gas and maintenance.

Since, Joshua pay the driver $25 per hour of driving

So for x hours pay  $ 25x

And also has an expense of $2 per mile driven for gas and maintenance

So for y miles pay $ 2y

Thus, for the driver drove an average of 50 miles per hour

Equation is,  y = 50 x

And since, Joshua's total expenses for the driver, gas and truck maintenance were $625.

So equation is,  25x + 2y = 625

Answer:

∠45°

Step-by-step explanation:

When looking at a unit circle, the only acute angle (an angle between

0° and 90°) that consists of an equal sine and cosine is 45°. This is because:

[tex]sin 45 = \frac{\sqrt{2} }{2}[/tex]

[tex]cos45 = \frac{\sqrt{2} }{2}[/tex]

45° is the only acute angle that contains an equal sine and cosine.

Answer:

45 degrees

Step-by-step explanation:

Since Sin(90-x) = Cos(x), we can find that the angle at which 90-x=x is 45 degrees. This corresponds to [tex]\frac{\pi }{4}[/tex] radians

Rotate it 90 degrees so that the would be the top.

Area of a trapezoid = (top+ bottom)/2 x height.

Each line on the graph is 2 units.

Top = 2

Bottom = 8

Answer:

(x-3)^2 + (y+2)^2 = 9^2

Step-by-step explanation:

x^2 -6x+y^2+4y-68 = 0

Complete the square

x^2 -6x+y^2+4y-68+68 = 0+68

x^2 -6x+y^2+4y = 68

Find the term to add for x

-6 /2 = -3  -3^2 = 9

Find the term to add for y

4/2 =2  2^2 = 4

Add 9 and 4

x^2 -6x+9+y^2+4y+4 = 68+9+4

(x-3)^2 + (y+2)^2 = 81

(x-3)^2 + (y+2)^2 = 9^2

The standard form is

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

Answer:

Fatima's unit rate is 9.5 minutes per mile.

Step-by-step explanation:

To compute the one unit value of a variable divide the total values of n variables by n.

It is provided that it took Fatima 19 minutes to run 2 miles.

Then the unit rate at which Fatima runs is:

[tex]\text{Unit Rate}=\frac{19}{2}[/tex]

                [tex]=9.5[/tex]

Thus, Fatima's unit rate is 9.5 minutes per mile.

Answer:

Step-by-step explanation:

Using set notation to answer the question.

let n(U) be the total number of people surveyed = 1000

n(L) be number of people that visited London = 310

n(P) be number of people that visited Paris = 222

n(P∩L) be number of people that visited both cities = 118

n(P∪L)' be number of people that visited none of the cities = x

n(U) = n(PUL) + n(PUL)'

We willl get n(PUL) using the formula;

n(PUL) = n(P)+ n(L)-n(P∩L)

n(PUL)= 222+310-118

n(PUL)= 414

Since n(U) = n(PUL) + n(PUL)'

1000 = 414+n(PUL)'

n(PUL)' = 1000-414

n(PUL)' = 586

586 peoples visitied none of these cities?
