Answer:

The answer is C. But I got 350.82

Step-by-step explanation:

The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48

The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82

Then we add up all the areas 302.82+48 to get 350.82

Because this answer is slightly different I would assume it is C.

Hip hop music makes up 75% of Landon's music library. If he has downloaded 120 hip hop songs, how many songs does Landon have in his music library? (Explain your answer/show your work)

Answers

Answer: 160 songs.

Step-by-step explanation:

75% hip hop music - 120 songs

100% all music - x songs

Let's write the proportion:

[tex]\dfrac{120}{75} =\dfrac{x}{100} \\\\75x=120 \cdot 100\\75x=12000\\75x : 75 = 12000 : 75\\x = 160[/tex]

Thus, Landon have 160 songs in his music library.

This is (compound) probability: Picking two numbers from 1-10 and getting a multiple of 3 both times.

Answers

Answer:

There are 10 counters in the bag and you want the 4

As their is only one for the probability is

1/10

There are now 9 counters left in the bag.

You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)

There are only four even counters in the bag of nine counters so the probability is

4/9

As you want both of these to occur, you need to multiply them

1/10 x 4/9 = 49/90

Step-by-step explanation:

The probability of getting a multiple of 3 both times is 2/30.

What is the probability?

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

We are randomly picking two numbers from 1-10.

Multiple of 3 between 1 and 10 are 3, 6, 9.

To find the probability:

Here, we are considering the that the numbers are chosen without replacement.

The probability of getting a multiple of 3 both times,

= 3/10 x 2/9

= 6/90

= 2/30

Therefore, the probability is 2/30.

So I got this question wrong and am wondering how I can get 352 square feet as my answer since that is what my teacher got and I don't know she got that so can someone plz help explain

Answers

Answer:

you have four walls. two of them 12*8 and other two is 10*8 ( we used 8 in both because its the height of the room) . so it goes( 2*12*8)+(2*10*8) and it goes 352

Step-by-step explanation:

lets say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper .

for walls A= 2*12*8=192

for walls B=2*10*12=160

in total you need 160+192= 352 square feet wallpaper

ribbon she needed 0.625 ft. How many ribbons could she make from
her roll?

Answers

Answer:

She can make 97 ribbons from her roll

Step-by-step explanation:

30.8 divided by 0.625 is 97.28, but the friends would like whole rolls, so I got 97

Answer:

Robin can make 49.28 ribbons. Or if you wish to round, 49 ribbons.

Step-by-step explanation:

Her roll of ribbon is 30.8 ft long.

She needs 0.625 ft for each ribbon.

Divide 30.8 by 0.625

30.8 ÷ 0.625 = 49.28

Each of these equations holds true for one value of x from the set {5, 12, 15, 18}. Arrange the equations in increasing order of the x-values that make them true.
x + (x − 10) = 26
6x − 15 = 75
2(2x − 1) = 46
5x − 3x = 10

Answers

Answer:

5x - 3x = 10

2(2x - 1) = 46

6x - 15 = 75

x+(x - 10) = 26

Step-by-step explanation:

5x - 3x = 10

2x = 10 Divide by 2

x=5

2(2x - 1) = 46 Distribute the 2

4x - 2 = 46 Add 2

4x = 48 Subtract by 4

x = 12

6x - 15 = 75 Add 15

6x = 90 Divide by 6

x=15

x + x - 10 =26 Add the x's together and the 10

Whats the answer !! olar eclipses are astounding. When the moons shadow moves over the earth, it can block the sun. The eclipse can be partial or total. In a partial solar eclipse, the sun looks like a wheel of cheddar cheese that has a big bite missing from its side. Partial solar eclipses are more common than total solar eclipses, but both are unusual and awesome. In a total solar eclipse, the view of the sun changes more radically. The bright ball of light seems to transform into a dark black circle. Around the dark circle, there are swirls of light. The bright white light flows out from the black core, reminding some people of the head of a flower. When people see the magnificent view, they marvel. They wonder about things bigger and more powerful than themselves.Solar eclipses are rare. Two conditions have to occur simultaneously for the sun to be eclipsed by Earths moon. First, there needs to be a new moon. Second, the moons orbit has to cross Earths orbit. Lets talk about the new moon first. We say that there is a new moon when the moon moves between Earth and the sun. The new moon is sometimes called the dark moon because, from Earths perspective, no light is shining on it at that time. As a consequence, people on Earth cant see it. From Earths perspective, there is a new moon about every 29.5 days. Now lets talk about the second condition for a solar eclipse. Solar eclipses only happen when the moon is in line with the ecliptic, the path the sun seems to take each year. That ideal alignment does not happen very often because the moons orbit around Earth is 5 degrees off from the annual path of the sun. Put another way, the moon moves at an angle, and that usually prevents its shadow from falling on Earth.Understanding shadows and solar eclipses will help us understand why some eclipses are partial and some are total. When the sun is behind the moon, the moon casts a shadow. However, because the sun, Earth, and moon are not exactly aligned, the new moons shadow often falls in space. But every once in a while, the moon temporarily crosses the suns path, the ecliptic. In that moment, the new moons shadow actually touches Earth, causing an eclipse. There is a partial solar eclipse when the moon is farther away from Earth. In that case, only its lighter outer shadow reaches Earth and only part of the sun is blocked. But when the moon is closer to Earth, both its light outer shadow and its dark inner shadow reach Earth. In that case, there is both a partial and a total solar eclipse. People standing in the outer shadow see a partial eclipse, and people standing in the inner shadow see a total eclipse.If you are lucky, you may one day stand in a shadow of the moon. Then you, too, will see a spectacular solar transformation.Based on the information in the passage, what is the most likely reason why the suns path is called the ecliptic?AThe suns path is as astounding as an eclipse.BEclipses happen when the moon crosses the suns path.CEclipses are vast, and the path of the sun is also vast.DThe sun only moves when there is an eclipse. The figure shows five points. A point has been translated right and up.On a coordinate plane, point A is (negative 2, 2), point C is (negative 2, negative 1), point B is (2, negative 3), point D is (3, negative 1) and point E is (3, 2).Based on the graph, which statements about the points could be true?
