The scale factor of two similar hexagons is 5:12. The smaller hexagon has an area of 24 square units. What is the area of the larger hexagon?

**Answer: **[tex]138.24\ \text{square units}[/tex]

**Step-by-step explanation:**

Given

The scale factor of two similar hexagons is 5:12.

The smaller hexagon has an area of 24 square units

we know, the ratio of two similar figures is equal to the square of the scale factor.

Suppose the area of the larger hexagon is A

[tex]\therefore \dfrac{24}{A}=\left[\dfrac{5}{12}\right]^2\\\\\Rightarrow A=\left[\dfrac{12}{5}\right]^2\times 24\\\\\Rightarrow A=138.24\ \text{square units}[/tex]

Mr chow is buying rolls of paper for the school. This is a lost of the suppliers, the size of their rolls, and their cost per roll. supplier x sells 25 meter rolls for 18.98, supplier y sells 30 meter rolls for 21.89, supplier z sells 40 meter rolls for 29.59 to the nearest cent what is the cost per meter for a roll of paper from the least expensive supplier

**Answer:**

0.73

**Step-by-step explanation:**

** cost per meter for a roll of paper = total cost / total meter of rolls sold**

Supplier x = 18.98 / 25 = 0.76

Supplier y = 21.89 / 30 = 0.73

supplier z = 29.59 / 40 = 0.74

the lowest per unit cost is 0.73

The diagonals of a rhombus are at right angles to each other, then

∠ 1 = ∠ 2 = ∠ 3 = 90° so

10x = 90 ( divide both sides by 10 )

x = 9

x + y = 90

9 + y = 90 ( subtract 9 from both sides )

y = 81

9z = 90 ( divide both sides by 9 )

z = 10

**Answer:**

X is about 58.41 degrees

**Step-by-step explanation:**

For this problem, lets use sine, since we have the opposite angle from x and we have the hypotenuse.

Therefore, with the equation for sine, we would get

sin(x) = 23/27

sin(x) = 0.851

Now, since we're solving for an angle, inverse it by adding a -1 to move over the sin.

x = sin-1 23/27

Last, use a calculator to get the answer.

X is about 58.41 degrees

Based on the data plotted, choose all that are correct.

A good line of best fit for the data is y = 15x + 55.

The data on the scatter plot shows a negative relationship.

If a student studies for 6 hours, they will receive a grade of about 100.

In general, the longer time spent studying, the higher the student's grade.

**Answer:**

- If a student studies for 6 hours, they will receive a grade of about 100.

- In general, the longer time spent studying, the higher the student's grade.

**Step-by-step explanation:**

**Given**

See attachment for plot

**Required**

Select all correct options

**First, we determine the equation of best fit.**

**Pick two corresponding points on the plot**

[tex](x_1,y_1) = (2,70)[/tex]

[tex](x_2,y_2) = (4,85)[/tex]

**Calculate slope (m)**

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

[tex]m = \frac{85 - 70}{4-2}[/tex]

[tex]m = \frac{15}{2}[/tex]

[tex]m = 7.5[/tex]

**The equation is then calculated as:**

[tex]y = m(x - x_1) + y_1[/tex]

**This gives:**

[tex]y = 7.5(x - 2) + 70[/tex]

[tex]y = 7.5x - 15 + 70[/tex]

[tex]y = 7.5x +55[/tex]

**The above represents the line of best fit.**

By comparison, (a) is incorrect

**We calculate the slope to be:**

[tex]m = 7.5[/tex]

Since the slope is positive, then the relationship is positive (b is incorrect)

**Also, the positive slope implies that, as x increases, y also increase.**

*Hence, (d) is correct.*

**For (c), we substitute 6 for x in the calculated equation of best fit**

[tex]y = 7.5x +55[/tex]

[tex]y = 7.5 * 6 + 55[/tex]

[tex]y = 45 + 55[/tex]

[tex]y = 100[/tex]

*This shows that (c) is true because 6 hours of study gives a grade of 100*

Which set of ordered pairs represents y as a function of x?

O {(-4, 0),(-2,2).(-4,-2), (-2, 4),(-4, - 4)}

{(0,4), (1,7),(1,10), (2, 13), (3, 16)}

{(3, 3), (-1,-1),(-2,-2), (4,4),(-4,-4)}

Circle A has center of (4, 6) and a radius of 5, and circle B has a center of (1, 0) and a radius of 15. What steps will help show that circle A is similar to circle B? (5 points) Group of answer choices Reflect circle A over the y-axis. Dilate circle A by a scale factor of 3. Translate circle A using the rule (x − 3, y + 6). Rotate circle A 180° about the center.

**Answer:**

Divide and then multiply the smaller ratio to get an equal ratio to the first one

**Step-by-step explanation:**

It helps a lot with algebra

**Answer:**

Dilate circle A by a scale factor of 3.

**Step-by-step explanation:**

In order to show if two triangles are similar you have to translate and dialate one of the triangles to compare it to the other one. So A and D are not it. The formula for C is incorrect so therefore the answer is B. Also i took the test :D

Please help and give an explanation on how to find the value of x

**Answer:**

x = 30

2x =60

**Step-by-step explanation:**

the angle is a right angle- so that means it’s a 90 degree angle

so let’s set up an equation..

We get 90 degrees when we add 2x Plus x

So 2x + x = 90

then, 3x = 90

x= 30

**you Can check your Answer by: **

Do 2 times 30 = 60

and then 60+ 30

you will Get 90

**Answer:**

A. 72π m^3

**Step-by-step explanation:**

The radius of the cone would be half the diameter, or 6m.

The formula for the volume of a cone is:

V= (πr^2h) / 3

We can substitute what we have:

V = (π * (6)^2 * 6 )/ 3

V = (216 π) / 3

**V = 72π m^3**

a box contains 44table tennis balls having same shape and size.Among them 33 are black and remaining balls are red .two balls are drawn randomly one after another without replacement show the probability of all posible outcomes in a tree diagram.

**Answer:**

The probability that both balls are red is 5.81%, that one is red and one black is 38.36%, and that both are black 55.81%.

**Step-by-step explanation:**

Given that a box contains 44 table tennis balls having the same shape and size, and among them 33 are black and remaining balls are red, if two balls are drawn randomly one after another without replacement, to show the probability of all possible outcomes the following calculations must be done:

Red + red:

11/44 + 10/43 = 0.25 x 0.2325 = 0.0581

Red + black:

11/44 + 33/43 = 0.25 x 0.7674 = 0.1918

Black + red:

33/44 + 11/43 = 0.75 x 0.2558 = 0.1918

Black + black:

33/44 + 32/43 = 0.75 x 0.7441 = 0.5581

19.18 x 2 = 38.36

Therefore, the probability that both balls are red is 5.81%, that one is red and one black is 38.36%, and that both are black 55.81%.

Read this excerpt about the Vietnam War from "Ambush" by Tim O'Brien:When she was nine, my daughter Kathleen asked if I had ever killed anyone. She knew about the war; she knew I'd been a soldier. "You keep writing war stories," she said, "so I guess you must've killed somebody." It was a difficult moment, but I did what seemed right, which was to say, "Of course not," and then to take her onto my lap and hold her for a while. Someday, I hope, she'll ask again. But here I want to pretend she's a grown-up. I want to tell her exactly what happened, or what I remember happening, and then I want to say to her that as a little girl she was absolutely right. This is why I keep writing war stories: He was a short, slender young man of about twenty. I was afraid of him-afraid of something-and as he passed me on the trail I threw a grenade that exploded at his feet and killed him. . . . Even now I haven't finished sorting it out. Sometimes I forgive myself, other times I don't. In the ordinary hours of life I try not to dwell on it, but now and then, when I'm reading a newspaper or just sitting alone in a room, I'll look up and see the young man coming out of the morning fog. I'll watch him walk toward me, his shoulders slightly stooped, his head cocked to the side, and he'll pass within a few yards of me and suddenly smile at some secret thought and then continue up the trail to where it bends back into the fog.
