Ashley is studying circle O, shown below. She wrote the steps below. What did Ashley derive?

Answer:

D. 90°

Step-by-step explanation:

6x + 4x - 1 + 2x + 1 = 180

12x = 180

x = 15

6x = 6 * 15 = 90

Answer: D. 90°

Answer:

25%

Step-by-step explanation:

30/40 = 0.75 = 75% paid

100-75 = 25% discount

Answer:

[tex]25\%[/tex]

Step-by-step explanation:

To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;

[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]

Substitute in the given values;

[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]

Solve;

[tex]\frac{10}{40}=\frac{percent}{100}[/tex]

Simplify,

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

Cross products,

[tex]100 = 4(percent)[/tex]

Inverse operations,

[tex]100=4(percent)\\/4\\\\25 = percent[/tex]

Answer:

Range = {3, -1, 15}

Step-by-step explanation:

Domain = {0,2,-6}

function : y= -2x + 3

We replace the value of x with domain,

when x = 0

y = -2 × 0 + 3

y = 3

When x = 2

y = -2 × 2 + 3

y = -1

When x = -6

y = -2 × -6 + 3

y= 12 + 3

y = 15

Answer:

the possible answer would be A, 6.

Step-by-step explanation:

6/2 is equal to 3 wholes. 7 minus 3 is 4. the sign > is used to indicate that the left number is greater than the right number, which is 3.  4 > 3 would be shown. this means that 6, or A, is the answer! :)

(6 IS ALSO THE ONLY OPTION. I NOTICED IT SAYS “ALL ANSWERS“

Answer:

±2√10

Step-by-step explanation:

Given the equation 40 - x^2 = 0

Add x^2 to both sides

40 - x^2 + x^2 = 0+ x^2

40 = x^2

x^2 = 40

x = ±√40

x = ±√4 * √10

x = ±2√10

Hence the value of x is ±2√10

Answer:

Mia spent 68 dollars.

Step-by-step explanation:

The equation would be 2(13.50) + 4(10.25) = x

Solving for the first part, you get 27 for adult tickets and 41 for the children tickets. When you add the two values, you get 68.

Answer:

False. All triangles must have a total of 180°. 60° + 60° + 70° = 190°.

Answer:

Option D) The opposite of 3 is -3. The absolute value of 3 is -3.

Step-by-step explanation:

On a number line, if you go three to the right from 0, you get 3. But if you go the same amount to the left of 0, you would get -3. I can't think of any other way to explain the opposite. The absolute value is usually the same number but the absolute value is usually the same number, but it's opposite.

I hope i explained that well and that you do well on your test!

Answer:

The ratio of the area of the rectangle to the area of the square is 0.75.

Step-by-step explanation:

The areas of the square and the rectangle are represented by following formulas:

[tex]A_{sq} = l^{2}[/tex] (1)

[tex]A_{re} = (1.5\cdot l)\cdot (0.5\cdot l)[/tex]  (2)

Where [tex]l[/tex] is the side length of the square.

The ratio of the area of the rectangle to the area of the square is:

[tex]\frac{A_{re}}{A_{sq}} = \frac{(1.5\cdot l)\cdot (0.5\cdot l)}{l^{2}}[/tex]

[tex]\frac{A_{re}}{A_{sq}} = 0.75[/tex]

The ratio of the area of the rectangle to the area of the square is 0.75.

Answer:

167.6 units^3

Step-by-step explanation:

Find the volume of the entire cone, and then divide the result by 4 to obtain the volume of the quarter cone:

Formula for the volume of a cone is V = (1/3)(base area)(height)

In this case the volume of the entire cone is V = (1/3)(pi)(8)^2*(10), or

670.21.

Taking 1/4 of this, we get the volume of the quarter cone:

670.21/4 = 167.6 units^3

Answer:

9

Step-by-step explanation:

x^2 - 2 = 79

The first step is to get rid of the 2 on the left side. You do this by adding two on both sides. You should then get x^2 = 81.

Now, you have the just take the square root of 81, which is 9.

Answer:

25

Step-by-step explanation:

Add 65+40 which is going to give you 105 then once you get 105 subtract 65-40 which is going to give you 25 the 105 is the total so the whole answer is 25

Answer:

D

Step-by-step explanation:

This equation is in factored form. Meaning you can find the x intercepts of the graph from it. All you need to do is find reverse the numbers inside the parentese. So if its negative, make it positive, if its positive, make it negative. By doing this, you should find that the x-intercepts of this graph are 2 and 3 and the donly graph with x-intercepts at these places is graph d.

Answer:

n = 4

im not good at explaining by text but i hope this helps

Step-by-step explanation:

3n - 8 = 4

you want the variable by itself so you will start with the number without the variable

3n - 8 = 4

next to the 8 is a - sign so it will is negative now it has to be the opposite

3n - 8 = 4

+8. +8

you cancel out the 8 and 4+8 is 12

now you have to do 12 ÷ 3 to get the variable by itself

12 ÷3 is 4
