What is Circle geometry?

The sum of the opposite angle of the quadrilateral within the circle is 360 degrees.

Given the following parameters

<B = 3x - 4

<D = 2x - 6

Equate both equations

<B + <D = 180

3x - 4 + 2x - 6 = 180

5x - 10 = 180

5x = 190

x = 190/5

x = 38

Determine the measure of <B and <D

<B = 3x - 4 = 3(38) - 4

<B = 110 degrees

<D = 2x - 6

<D = 2(38) - 6

<D = 76 - 6

<D = 70 degrees

Hence the measure of <B and <D are 110 degrees and 70 degrees

THREE expressions equivalent to –81x+27.

Answers

Hey there!

One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us [tex]\frac{-81x+27}{3}[/tex]. If we simplify this, we get [tex]-27x+9[/tex].

Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us [tex]\frac{-81x+27}{21}[/tex]. If we simplify this, we get [tex]-3x+1[/tex].

One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us [tex]1(-81x+27)+0[/tex].

The perimeter of a square is 52 meters. What is it area.

Answers

Answer:

169 meters

Step-by-step explanation:

13^2=169 (to find the area you square the length of each side)

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 12 m. The inner edge of the sidewalk is a circle with a radius of 8 m.

Write and simplify an expression for the exact area of the sidewalk.

Find the approximate area of the sidewalk. Use 3.14 to approximate π.

Answers

Answer:

The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m

The equation would be:

144 x 3.14 - 64 x 3.14 = 251.2

Step-by-step explanation:

First, you need to find out what the whole circle is:

The whole circle is 452.16

Then, find the inner circle :

8 x 8 x 3.14  

200.96

Last, subtract the whole by the inner:

452.16 - 200.96 = 251.2

at a certain college, the ratio of men to women is 6 to 5. If there are 1,500 men how many women are there?​

Answers

Answer:

1250 women

Step-by-step explanation:

1500 / 6 = 250

250 x 5 = 1250

hope this helps

Answer:

There are 1,250 women

Step-by-step explanation:

If the ratio of men to women is 6 to 5, and there are 1,500 men, the actual ratio of men to women is 1,500 to x, where x is equal to the amount of women at the college.

Since 6/5 is equal to 1,500/x, you cross multiply to find that 7,500 is eual to 6x.

Divide both sides by 6 to find that x is equal to 1,250 women.

Answers

9514 1404 393

Answer:

  C.  The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).

Step-by-step explanation:

The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.

The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.

Additionally, the x-term needs to match the result of multiplying out the factors.

  B.  (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)

  C.  (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)

The factors of C are zero when x=-1, x=5/2.

M = 95°

N = 67°

Step-by-step explanation:

6y + 5 + 4y + 7 + 18 = 180

10y + 30 = 180

10y = 150

y = 15

M: 6(15) + 5 = 95°

N: 4(15) + 7 = 67°

Verification: 95 + 67 + 18 = 180° (correct)

A cylindrical container has a diameter of 5 inches and a height of 12 inches. The container will be wrapped and delivered as a gift. What measurement is closest to the amount of wrapping paper needed to cover the container without overlap?

Answers

Answer:

Step-by-step explanation:

1. Write your formula

2. Plug it in

3. Solve

these steps will help you out with all of your surface area problems.

Like this

Since it is a diameter you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...

V = Bh                            (Pie is also known as 3.14)

your big (B) is (pie times r squared) Then you add your height.

so your formula will look like this...

V = pie times r squared...

the full formula will be...

V = (3.14) times (2.5 squared) times the height which in this case is (12)

everything together will be...

V = (3.14) (2.5^2) (12)

all you have to do is multiply all of that and you will get your answer.

The answer is...

V = 236 inches ^2                        (Just a tip, the ^ sign means to the power of)
