In The Diagram,the Measure Of Angle ACB Is 25 Degrees. What Is The Measure Of Angle AOB?

Answers

Answer 1

Answer:

m<AOB = 50°

Step-by-step explanation:

<ACB = 25° is an inscribed angle of the circle.

<AOB is a central angle of the circle.

Thus, based on the inscribed angle theorem which states that an inscribed angle is ½ the measure of the central angle, therefore:

m<ACB = ½(m<AOB)

Substitute

25° = ½(m<AOB)

Multiply both sides by 2

2*25 = m<AOB

m<AOB = 50°

The answer should be...

[tex]117 mm^3[/tex](if your supposed to do volume)

[tex]174mm^2[/tex](if your supposed to do surface area)

Step-by-step explanation:

volume:

3 x 3 x 3 = 27

10 x 3 x 3 = 90

27 + 90 = 117

surface area:

3 x 3 x 2 = 18

3 x 3 x 2 = 18

3 x 3 = 9

3 x 10 x 2 = 60

3 x 10 x 2 = 60

3 x 3 x 2 = 18

18 + 18 + 9 + 60 + 60 + 18 - 9 = 174

Use a graphical method to find estimates for the solutions of the simultaneous equations x^2 + y^2=2.25 y-x=1
NEED ASAP WILL MARK AS BRAINLIEST

Answers

Answer:

A) which graph represents the equation x^2 + y^2 = 2.25?

First, the general equation for a circle can be written as:

(x - a)^2 + (y - b)^2 = R^2

This is a circle of radius R centered in the point (a, b).

Then we can rewrite our equation as:

(x - 0)^2 + (y - 0)^2 = (√2.25)^2 = (1.5)^2

Then we have a circle centered at the point (0, 0) and with a radius equal to 1.5

Then we can see that the correct one is graph C.

b) Now we want to solve the system:

x^2 + y^2 = 2.25

y - x = 1

graphically.

To do it we need to graph both equations and see in which points do they intersect.

We already have the first equation graphed, so we only need to also graph the linear equation:

y - x = 1

y = 1 + x

An example of this can be seen in the graph below:

There we can estimate one of the intersections as (0.4, 1.4) and the other as (-1.4, -0.4)

Carol bought 2 pairs of jeans at 24 each and 3 shirts she spent a total of 75 before tax what is the cost of 1 shirt
A.$8
B.$17
C.$9

Answers

Answer:$9

Step-by-step explanation:Here's what we know:

2 * 24 + 3s = 75 (the pants ($24 each) and shirts all together is $75)

 

What we need to do is isolate s

Simplify:

48 + 3s = 75

subtract 48 from both sides:

48 + 3s - 48 = 75 - 48

3s = 27

Divide by 3:

3s / 3 = 27 / 3

s = 9

 

Shirts are $9 each.

Answer:

2 x 24 = 48

48 - 75 = 27

27 ➗ 3 = 9

so the cost of 1 shirt is $9

Find the area of this figure please

Answers

Answer:

A. 122cm^2

Step-by-step explanation:

We can find the area of this figure by finding the area of each rectangle, then combining the areas.

The formula for area of a rectangle is simple; the formula is length x width.

The first rectangle has side lengths of 12 and 6.      

12 x 6 = 72.

The area of the first rectangle is 72 cm.

Now, for the second rectangle.

Formula: length x width

10 x 5 = 50

The area of the rectangle is 50 cm.

Now we add both areas.

50 + 72 = 122 cm.

Therefore, the area of the figure is 122 cm^2.

Percent of change from 30 to 90?

Answers

Answer:

Step-by-step explanation:

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

Answer:

200%

Step-by-step explanation:

The change (increase) is 60.

60, divided by the original value 30, comes out to 2.

Multiplying this result by 100% yields 200%

Keeping promises is important because it helps build better relationships with the people around you. When you keep a promise it can show that you are a reliable and trustworthy person. If you maintain a promise it can strengthen the mutual trust between you and the other person. For example, your Mom asks you to go to the store and you promise her that you will go. You manage to keep your promise and now she has a little more trust in you than she did before. This conveys that maintaining a promise is a good way to show someone how dependable you really are.
