Which is a perfect square?

Answer: i have the answer to the first one good luck on your assignment!

Step-by-step explanation: 1. 12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric

she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds

each dog bed sells for 17.50.....5 * 17.50 = 87.50

87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==

Answer: I'm gonna answer the last one

Step-by-step explanation:

First lets add up Rosalva

1.5+0.69+1.04+2.1=5.33

Next lets do Jake

1,450+1,590+1204+1,977=6,221

We have two different measurements, we want them to be the same. We are gonna change Rosalva. One kilometer equals 1,000 meters. If u use the g o o g l e calculator it says that 5.33 kilometers equals 5330 meters. since u need to show work just multiple 5.33 by 1,000.

Last we need to find the difference soooooooo 6,221-5330=891 meter difference :)

Answer: 25%

Step-by-step explanation: 40-30= 10    10/40= .25

Answer: 90%

Step-by-step explanation:

Answer:

1. The area of land is 23.1 x 10^9 square meters in scientific notation

2. We can represent this area as 2.31 x 10^4 square kilometers in scientific notation

Hint: 1 square km is equal to 1 x 10^6

3. The unit square kilometers is more appropriate to represent the area of forest land scientific notation.

Answer:

B : 259.18in^3

Step-by-step explanation:

find the area of all the circles you have to use the formula A=πr2 and these are the sizes

smallest white : A≈63.62in

yellow 2nd circle: A≈153.94in

3rd circle white: A≈283.53in

largest yellow circle: A≈452.39in

first you have to start with the smallest circle which the area is 63.62 then you go to the 2nd circle which is yellow which the area is 153.94 since you are trying to find only the area of yellow you have to subtract 63.62 from 153.94 which you get 90.32 then you have to go to the 3rd circle which then you have to subtract the 90.32 from 283.53 which comes out to be 193.21 then you finish with the last circle which the area is 452.39 then you have to subtract the last 193.21 which comes out to be 259.18in

the reason you subtract every time you went to the bigger circle because that number was the opposite color if you had 2 yellows in a row you would have to add them just as an example.

Answer:

44 cm²

Step-by-step explanation:

To find the area of a compound figure like this, we can divide the shape into various rectangles and compute the areas of them separately before adding them together.

There are several ways to divide this shape, but for this we will section the shape into a 3×3 square, 4×2 rectangle, and a 3×9 rectangle.

To find the areas of them, multiple the length by the width.

For the 3×3 square at the top right-

[tex]A=3\cdot 3[/tex]

[tex]A=9[/tex]

The square is 9 cm².

For the 4×2 rectangle at the top left-

[tex]A=4\cdot 2[/tex]

[tex]A=8[/tex]

The rectangle is 8 cm².

For the 3×9 rectangle at the bottom-

[tex]A=3\cdot 9[/tex]

[tex]A=27[/tex]

The rectangle is 27 cm².

Now that we have the areas of each individual piece of the figure, we can add them together to find the total area of the shape.

[tex]A=9+8+27[/tex]

[tex]A=44[/tex]

The area of the figure is 44 cm².

I hope this helps ^^ Good luck :)

Step-by-step explanation:

Answer:

AC 4x + 16

Angle BEC is 72 degrees

Step-by-step explanation:

AE is 2x + 8, and AC is 2 times bigger, so 4x + 16

Angle EAD is the same as angle EDA, which is 54 degrees, a triangle has 3 sides measuring 180 degrees total, 54 + 54 = 108, so the last angle is 180 - 108 = 72, angle AED is 72, since angle BEC is the same as angle AED, it is also 72 degrees

Here is ur answer

Answer:So let's start by guesstimating the slopes:

the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.

Next let's look at the solution: the two lines intersect at the point (1, -1).

**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)

A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2

B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense

C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations

D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1

So the correct answer is:

C) y = 2x - 3 and y = −2x + 1

Sorry I don't know the answer but here's where you can find it! bit .ly/3gVQKw3

Answer:

151.7cm^3

Step-by-step explanation:

To work out the volume you have o multiply all the sides. In this case you have the measurements 10, 4.1, 3.7

Multiply:

10 * 4.1 = 41

41 * 3.7 = 151.7

Answer:

Volume = 151.7 cm3

Step-by-step explanation:

Multiply 3.7×4.1×10

which gives you th answer 151.7 cm3

Step-by-step explanation:

An atom is the smallest particle of matter holding the basic properties and characterstic of the matter. An atom consist of positive charged protons and chargeless neutrons at its centre and the negatively charged electrons are revolving around the nucleus. An atom do consist of energy levels corresponding to which the electrons revolve around the nuclues in the respective energy level.

Now a photon is an energy packet, or we can say a particle of light carring energy with it.

An atom is a particle of a matter and a photon is a particle of light.
