Find the missing length of the triangle

Answer:

the same number as the number of sides

lines of symmetry are in a regular polygon is the same number as the number of sides.

the correct option is (D)

A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly.

The number of lines of symmetry in a regular polygon is equal to the number of sides.

For example,

It has four lines of symmetry and four sides. A regular pentagon has 5 sides and 5 lines of symmetry.

Hence, lines of symmetry in a regular polygon is equal to the number of sides.

The verticies of J’K’L would be,  J'(-a, -b), K'(-c, -d), and L'(-e, -f).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, Triangle JKL is rotated 180 about the origin, resulting in triangle J’K’L.

Assuming the coordinates of J(a, b), K(c, d) and L(e, f).

We know a rotation of 180° to (x , y) ⇒ (- x, - y).

Therefore, The vertices of J’K’L would be,  J'(-a, -b), K'(-c, -d), and L'(-e, -f).

The constant rate of change is how much y increases every time x increases by 1. We might be confused because in this table, we see a number of points, but we don't see any consecutive x-values, so it might seem difficult. But no worries!

All you have to do is calculate using the formula, Δy divided by Δx. What does Δy divided by Δx mean?

All we have to do is look at two points. Let's take, for example, (-2, -10) and (2, -8).

-2 and 2 are the x-values of the points and -10 and -8 are the y-values of the points as coordinates are in the format of (x, y).

All we have to do is minus the y-coordinates and then proceed the minus the x-coordinates. The order does not matter, as in you can do either of these ways:

[(-10) - (-8)] ÷ [(-2) - (2)] = -2 / -4 = 1/2

or

[(-8) - (-10)] ÷ [(2) - (-2)] = 2 / 4 = 1/2

So the constant rate of change or the answer is 1/2.

Each answer is under each Part

1. What is the price of you pizza with all the toppings?                                

$16

The pizza costs 12 dollars, and each topping costs 1.75 dollars, there are 4 toppings, so it's 12 + 1.75*4 = 12 + 4 = 16 dollars.

2. How much will you pay in tax?                                                                

$0.80

It costs 16 dollars and tax is 5%, so 5% of 16. 16*5% = 16*0.05 = 0.8, so 0.8 dollars, or $0.80

3. What is the total cost including tax?                                                    

$16.80

Add the cost of the pizza with the tax, 16 + 0.8 = 16.8, $16.80

4. How much will each of you need to pay to cover the total price?

$4.20

There are 4 people total, You and 3 friends, so divide the total cost by 4, 16.80/4 = 4.2, so $4.20

The volume of the prism is 420 in³.

Option C is the correct answer.

We have,

From the figure,

Length = 7 in

Width = 5 in

Height = 12 in

Now,

To find the volume of the prism, we can use the formula:

Volume = Length * Width * Height

Substituting these values into the formula:

Volume = 7 * 5 * 12

Simplifying the expression:

Volume = 420 cubic inches

Thus,

The volume of the prism is 420 in³.
