Answer 1

Answer:

x = 10

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

12 +10x  = 81 + 31

Combine like terms

12 +10x = 112

Subtract 12 from each side

12-12+10x = 112-12

10x= 100

Divide each side by 10

10x/10 = 100/10

x = 10

Answer 2

Answer:

10

Step-by-step explanation:

Exterior angle = sum of interior angles

12 + 10x = 81 + 31

12 + 10x = 112

10x = 100

x = 10

the table shows the results of a survey that asks middle- and high-school students wether they read online news blogs. what percentage of all students read news blogs?

Answers

Answer:

40%

Step-by-step explanation:

The question they are asking is what percentage of all students read news blogs?

1.) You will use the total number of students that answered yes, which is 80.

2.) You will divide 80 from 200. 200 is the total number of students that took the survey.

3.) 80/200= 0.4  

4.) You will then multiply by 100 to get your percentage.

5.) 0.4 x 100 = 40%

Example:
This does/does not make a right triangle because...

Answers

Answer/Step-by-step explanation:

This does not make a right triangle because the Pythagorean Theorem shows that 4^2 + 6^2 does not equal 8^2.

16 + 36 = 64

52 doesn't equal 64.

Answer:

This does not make a right triangle because according to the pythagorean theorem, a^2+b^2=c^2. 16+36 does not equal 64, thefore, the triangle with the following sides is not a right triangle.

A dog run has an area of at least 150 square feet. The length of the run has to be 12 feet. What us the width of the run?​

Answers

Answer:

The width is 12.5

Step-by-step explanation:

so you would do 150 divided by 12 which would give you 12.5 so the width has to be 12.5 because length times width = area and 12.5 time 12 = 150

Hope this helped :3  o(* ̄▽ ̄*)ブ

Answer:

12.5 ft

Step-by-step explanation:

Area of a rectangle of length L and width W:  A = L * W

Then 150 ft^2 = (12 ft)(width), and so:

(width) = (150 ft^2) / (12 ft) = 12.5 ft

[only answer the 2nd and the 3rd]

Answers

Answer:

2. 120 cm^2

3. 3,750 cm^2

Step-by-step explanation:

To find the surface area of a rectangular prism, find the surface area of each side, then add them together.

2. There are two different shapes of faces on this prism (as with all rectangular prisms). One face's surface area has a measure of 4 cm by 6m. To find the surface area of that face, multiply each side length. 4 * 6 = 24. Let's call this length A.

Then, find the surface area of the other face. The other face has a measurement of 4 cm by 3 cm. 4 * 3 = 12. Let's call this length B.

Now, find the amount of each face on the prism. Length A appears 4 times: the front, back, top, and bottom are all the same shape. Length B appears 2 times: the left and right sides. Therefore, multiply length A's surface area by 4 and length B's surface area by 2.

24 * 4 =  96

12 * 2 = 24

Lastly, add both numbers together.

96 + 24 = 120

Adding the label, we get the final answer: 120 cm^2.

3. Now, apply the same steps to problem #3.

One face has a measurement of 45 cm by 25 cm. This means that the surface area of that face is 1,125 cm. Let's call this length A.

The other face has a measurement of 15 by 25. This means that the surface are of that face is 375 cm. Let's call this length B.

Length B appears 4 times, and length A appears twice. Evaluating 375 * 4, we get 1,500. Evaluating 1,125 by 2, we get 2,250.

Lastly, adding 2,250 to 1,500 and adding the label, we get the final answer: 3,750 cm^2.

What is the twentieth term of the arithmetic sequence described by the
equation an= 3n - 10?

Answers

Answer:

The twentieth term is 50.

Step-by-step explanation:

The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:

a1 = 3*1 - 10

a1 = -7

Therefore to find the twentieth term we need to make n equal to 20. This is done below:

a20 = 3*20 - 10

a20 = 60 - 10

a20 = 50

The twentieth term is 50.

Find the volume of a cylinder when the radius is 9 cm and the length is 20 cm

Answers

Answer:

5089.38 cm OR 1620π

Step-by-step explanation:

The formula for the volume of a cylinder is π[tex]r^{2}[/tex]h so if the radius is 9, 9 squared is 81. We multiply 81 by 20 and that gives us 1620. So in terms of pi, it is 1620π but if you just multiply it all together, it gives you 5089.38 cm. Please mark me brainliest and I hope this helped!

Based on the radius and the length of the cylinder, we can calculate that its volume is 5,091.43 cm³.

The volume of a cylinder can be calculated by the formula:

= π x radius² x height

Solving will give:

= π x 9² x 20

= π x 81 x 20

= 5,091.43 cm³

In conclusion, the volume is 5,091.43 cm³

Suppose f(x) = x2. What is the graph of g(x)= 1/3f(x)

Answers

Answer:

Step-by-step explanation:

The graph of f(x) = x^2 is a parabola opening up and with vertex at (0, 0).

The graph of (1/3)f(x) is also a parabola that opens up and has vertex at (0, 0), but this new graph has been vertically compressed by a factor of 3.

The graph of g(x) = 1/3 f(x) is parabola. (as shown in the following image.)

What is the graph of a function?

"The graph of a function f is the set of all points in the plane of the form (x,  f(x))."

For given example,

f(x) = x²

The graph of a function f(x) would be a parabola with vertex at origin (0, 0).

And g(x) = 1/3 f(x)

⇒ g(x) = 1/3 (x²)

We know, the greater the quadratic coefficient, the narrower the parabola and the lesser the quadratic coefficient, the wider the parabola.

Since for a parabola g(x) the quadratic coefficient is 1/3.

This means the parabola g(x) is wider than the parabola f(x)

So, the graph of g(x) is the graph of f(x) scaled by 1/3 units.

The graph of g(x) is parabola (as shown in following figure)

Find the slope and y intercept

Answers

Answer:

2) slope = -4, y-intercept = 140

Step-by-step explanation:

to find the slope take rise over run, for y-intercept its always where ever the 0 falls on the x line.

1) since the rise(y) = 6, and the run(x) = 2, it becomes 6/2 making your answer 3.  They y-intercept is x = 0, y = 1.

2) The rise(y) = -20, and the run(x) = 5, it becomes -20/5 making your answer -4. The y-intercept is x = 0, y = 140.

Hey there! I'm happy to help you! :)

We see that there are 160 songs in total. Let's split them up into groups of rock, country, and pop.

ROCK

Our problem says that 3/8 of the songs are rock songs. We know that we have 160 songs. We just need to multiply 3/8 by 160 and we will have the number of rock songs.

3/8*160=60

Therefore, we have 60 rock songs.

COUNTRY

We see that 25% of our songs are country songs. 25% is the same thing as 1/4, or 0.25. We can multiply this by our total number of songs to see how many are country.

0.25(160)= 40

We have 40 country songs.

POP

All we have in the problem is that the remaining songs are pop. The nice thing is is that we already know how many rock and country songs we have, so we can simply subtract those from 160 and we will then be able to tell how many pop songs there are.

160-60-40= 60

Therefore, there are 60 pop songs.
