The scale factor from triangles ABC to XYZ IS 6.

Option A is the correct answer.

What is a scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object,

We have,

ΔABC and ΔXYZ

The corresponding sides are:

AB = XY

BC = YZ

AC = XZ

Now,

We see that,

XY = 6 x AB

YZ = 6 x BC

XZ = 6 x AC

So,

The scale factor is 6.

Thus,

The scale factor from triangles ABC to XYZ IS 6.

It’s impossible what are you doing Distributed property or solving for x?

Answer:

x = 4.5

Step-by-step explanation:

Let's solve this together!

First you would want to multiply 6 and x:

6×2 = 12

x×2 = 2x

Then you would want to subtract 12 from 3:

3+12 = 9

Then divide 9 by 2:

9÷2 = 4.5

x=4.5

That's it!

In a painting, The Great Pyramid of Giza is 45 centimeters tall.
If the pyramid is actually 146.5 meters tall, find the scale.

Answers

Answer:

The scale is: 1 cm = 3.26 meter

Step-by-step explanation:

Given

Height of Pyramid in Painting = [tex]H_p = 45 cm[/tex]

Actual Height of Pyramid = [tex]H_a = 146.5m[/tex]

In order to find the scale, we can find the ratio between actual height and height in painting.

The ratio can be found by dividing the actual height by height in painting

[tex]Scale = \frac{H_a}{H_p}\\= \frac{146.5}{45}\\=3.25555 m/cm[/tex]

Rounding off to nearest hundredth

= 3.26

This means that the scale is:

1 cm = 3.26 meter

Identify the center and radius of the circle (x+4)^2 + (y-2)^2=16

Answers

The equation for a circle is x^2+y^2=r^2 so the radius is the square root of 16 which is 4. Then you take y-2 and set it equal to 0. This gives you y=2 as the y coordinate of the center. You then set x+4 equal to 0 which gives you x=-4 which is the x coordinate of the center. So the radius is 4 and the center is at (-4,2)

If X represents the number of pictures, write an equality to represent the situation!

Answers

Answer:

The Drama Club needs to sell more than 3 pictures to make a profit.

The inequality 10x ≥ 2.55x +25  represents the situation.

Step-by-step explanation:

Given that:

Rent for lighting equipment = $25

Price per print = $2.55

Selling price of one picture = $10

x be the number of pictures.

Selling price * No. of pictures sold ≥ Price of per print * pictures printed + rent

10x ≥ 2.55x +25

10x-2.55x≥25

7.45x≥25

Dividing both sides by 7.45

[tex]\frac{7.45x}{7.45}\geq \frac{25}{7.45}\\x\geq 3.35[/tex]

Hence,

The Drama Club needs to sell more than 3 pictures to make a profit.

The inequality 10x ≥ 2.55x +25  represents the situation.

Answer:

Train B is traveling faster.

Step-by-step explanation:

To find which train is faster, divide the distance the train traveled by the elapsed time for each train:

Train A:

Distance traveled is 12.5 meters.

Elapsed time is 1 second.

12.5 ÷ 1 = 12.5

Train A travels 12.5 meters per second.

Train B:

Distance traveled is 100 meters.

Elapsed time is 4 seconds.

100 ÷ 4 = 25

Train B travels 25 meters per second.

25 is greater than 12.5, so train B travels faster.

Answer these please i will mark brainliest Answer NOW!The day had been one of those unbearable ones, when every sound had set her teeth on edge like chalk creaking on a blackboard, when every word her father or mother said to her or did not say to her seemed an intentional injustice. And of course it would happen, as the end to such a day, that just as the sun went down the back of the mountain and the long twilight began, she noticed that Rollie was not around.Tense with exasperationshe would simply explode if Mother got goingshe began to call him in a carefully casual tone: "Here, Rollie! He-re, boy! Want to go for a walk, Rollie?" Whistling to him cheerfully, her heart full of wrath at the way the world treated her, she made the rounds of his haunts; the corner of the woodshed, where he liked to curl up on the wool of Father's discarded old windbreaker; the hay barn, the cow barn, the sunny spot on the side porchno Rollie.Perhaps he had sneaked upstairs to lie on her bed where he was not supposed to gonot that she would have minded! That rule was a part of Mother's fussiness, part too of Mother's bossiness. It was her bed, wasn't it? But was she allowed the say-so about it? Not on your life. They told her she could have things the way she wanted in her own room, now she was in her teens, buther heart raged against the unfairness as she took the stairs stormily, two steps at a time, her pigtails flopping up and down on her back. If Rollie was on her bed, she was just going to let him stay right there, and Mother could shake her head and mumble all she wanted to. But he was not there. The bedspread and pillow were crumpled, but not from his weight. Earlier that afternoon, she had flung herself down to cry there. And then she couldn't. Every nerve in her had been twanging, but she couldn't cry. She could only lie there, her hands doubled up hard, furious that she had nothing to cry about. Not really. She was too big to cry just over Father's having said to her severely, "I told you if I let you take the chess set you were to put it away when you got through with it. One of the pawns was on the floor of our bedroom this morning. I stepped on it. If I'd had my shoes on, I'd have broken it."Well, he had told her to be sure to put them away. And although she had forgotten and left them, he hadn't forbidden her ever to take the set again. No, the instant she thought about that, she knew she couldn't cry about it. She could be, and she was, in a rage about the way Father kept on talking, long after she'd got his point, "It's not that I care so much about the chess set," he said, just leaning with all his weight on being right, "it's because if you don't learn how to take care of things, you yourself will suffer for it later . . . .
