Answer:

[tex]x=8\sqrt{5}[/tex]

Step-by-step explanation:

I will assume the following:

The challenge of this exercise comes from using the pythagorean theorem and setting up a few equations.

Given that we have a segment 36 units long and another segment that is 16, it is trivial to get the other segment, 20. Additionally, there are two sides that I want to name so that way I can make a couple of substitutions. I will call these side a and side b. (see attachment 1)

Now comes with setting up three equations. I will start with the two smaller triangles, using side a and side b. See attachments 2 and 3.

Now with the big triangle. I will set up one last equation. See attachment 4.

Given what we know about attachment 2 and 3, we can make two substitutions. See attachment 5. I assume you know how to do the rest and arrive at your only real solution.

We can write the coordinates of the vertices of the triangle after dilation by a scale factor as -

C'(9, 6)

B'(0, 12)

A'(12, 12)

Dilation is the enlargement or shrinking of the coordinates.

Given is a triangle as shown in the image.

The coordinates of the vertices of the triangle are -

C(3, 2)

B(0, 4)

A(4, 4)

For the dilation by a scale factor of {K} = 3, we can write -

C'(3 x 3, 2 x 3) = C'(9, 6)

B'(0 x 3, 4 x 3) = B'(0, 12)

A'(4 x 3, 4 x 3) = A'(12, 12)

Therefore, we can write the coordinates of the vertices of the triangle after dilation by a scale factor as -

C'(9, 6)

B'(0, 12)

A'(12, 12)

Answer:

The Girl Guides will need 32 walkers in order to reach their goal. The equation used to find the amount of walkers is 24x + 232 = 1000.

Step-by-step explanation:

24x + 232 = 1000

24x + 232 - 232 = 1000 - 232

24x = 768

24x ÷ 24 = 768 ÷ 24

x = 32

Answer:

122.5

Step-by-step explanation:

If it triples her followers per 6 months then it gives her half of her followers in one month. So 35 times 3.5 which is 122.5

After [tex]7[/tex] months, Ashton will have [tex]25,515[/tex] followers.

Modelling is the process of creating a mathematical representation of a real-world scenario to make a prediction or provide insight.

We have,

Number of followers [tex]=35[/tex]

So, Every month increase is triple i.e. [tex]3[/tex] times for next [tex]6[/tex] months.

So,

According to the question,

Every month increase [tex]=\ 3\ *\ Current\ Follower[/tex]

So,

Followers after [tex]7[/tex] months [tex]= 35*(3)^6[/tex]

Because followers are increasing at the rate of three times per month,

So,

Followers after [tex]7[/tex] months [tex]= 35*(3)^6=25,515[/tex]

Hence, we can say that After [tex]7[/tex] months, Ashton will have [tex]25,515[/tex] followers.

Answer:

The $1 belongs to the cash box

Step-by-step explanation:

Given

See attachment for complete question

Required

Determine if the $1 belongs to the cash box or not

Represent singles with s and couples with c.

From the attachment, we have:

[tex]s + c = 47[/tex] --- total attendance

[tex]5s + 4c =200[/tex] --- ticket sold

Solve for s and c.

Make s the subject in (1)

[tex]s = 47-c[/tex]

Substitute 47 - c for s in (2)

[tex]5(47 - c) + 4c = 200[/tex]

Open bracket

[tex]235 - 5c + 4c = 200[/tex]

[tex]235 - c = 200[/tex]

[tex]c = 235 - 200[/tex]

[tex]c = 35[/tex]

This means that the total individual which makes up the couples are 35. This is not possible because couples are in 2's and the total should be an even number.

So, we can conclude that the $1 belongs to the cash box

Answer:

4

Step-by-step explanation:

Normally you would have to figure out the distance of the x- and y-components and use the Pythagorean Theorem; however, because the y-coordinates of both points are the same, you only need the x-coordinates.

You have the first point back 3, and the second point forward 1.

So starting at -3, you move 4 points to get to 1.

((-3 to -2 (1), -2 to -1 (2), -1 to 0 (3), 0 to 1 (4)))

Answer:

2x ( 5x + 6 )

Step-by-step explanation:

What you want to do is simplify each of the answer choices you have and see which one is the same as the expression given.

2x ( 5x + 6 ) Distirbute 2x to 5x + 6.

2x times 5x equals 10x² because x times x equals x².

2x times 6 equals 12x.

Once you simplify this expression, you get 10x² + 12x which is the expression you started with!

Answer:

The first option (the uppermost) is correct.

Step-by-step explanation:
