Answer:

52°

Step-by-step explanation:

By remote interior angle theorem of a triangle:

115° = 63° + x° ( x is the vertical angle of one interior angle of the triangle)

x° = 115° - 63°

x° = 52°

x = 52

Answer:

66.666% or 66.7% if rounded to the nearest one decimal place

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:

  B.  -1 ≤ y ≤ 1

Step-by-step explanation:

The range is the vertical extent of the function. Here, it appears the function is a sine function (y=sin(x)). The least value of the function is -1; the greatest value is +1. The function can take on any value between these extremes.

An appropriate description of the range is ...

  -1 ≤ y ≤ 1

Answer:

y+7= -6/5(x+3)

Step-by-step explanation:

Point slope form for a line is given by

y-y1 = m(x-x1) where m is the slope and (x1, y1) is a point on the line

y - -7 = -6/5(x - -3)

y+7= -6/5(x+3)

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

Height = 6

Area = (2+8)/2x6 = 30square units

Answer:

answer is the seconddd one

Answer:

Height: 48

Base: 34

Step-by-step explanation:

The formula for a triangle is 1/2(base)(height)

1/2(3x+10)(6x) = 816

18x² + 60x = 1632

18x² + 60x - 1632 = 0

Then, we use the Quadratic formula

x = (-60 ± √3600 + 117,504)/36

x =( -60 ± 348/36)

x = 288/36

x = 8

3(8) + 10

= 34

6(8) = 48

Therefore the dimensions are:

Height: 48

Base: 34

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?

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

Answer: The lower quartile is 6

Step-by-step explanation: To find the lower quartile of a set of data, we can find the median of the data and then find the median of the first half. This strategy is similar to dividing a cake into halves, and then dividing one of the halves in half so that you end up with a quarter of the cake.

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)

Step-by-step explanation:

2x -6 ≥ 6(x-2)+8

Distribute

2x - 6≥6x -12+8

Combine like terms

2x - 6≥6x -4

Subtract 2x from each side

2x-6-2x ≥6x-2x-4

-6 ≥4x-12

Add 4 to each side

-6+4 ≥4x-4+4

-2 ≥4x

Divide by 4

-2/4 ≥4x/4

-1/2≥x

Closed circle at -1/2

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:

it's either x=75° and y =85°

or x= -75° and y= -85°

because it's below!

Answer:

x=95°

y=105°

Step-by-step explanation:

opposite angle of a cyclic triangle are supplementary.

x+85=180

x=180-85=95°

y+75=180

y=180-75=105°

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.

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:

(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
