Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).

Plot triangles PQR and P′Q′R′ on your own coordinate grid.

Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)

Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)

Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)

Answers

Answer 1

Answer:

The scale factor from triangle PQR to P'Q'R' is 1/4.

The length of each side of the triangle is divided by 4, in other words it is multiplied by the scale factor of 4.

If P'Q'R" is reflected over the y-axis the new points would be: (1, 0) (0, 1) and (-2, 1).

No, the triangles are not congruent. There was a dilation of 1/4 in the triangles.

The volume of a rectangular prism is 50 5/8 cubic inches.
The dimensions are given below.
What is the missing value in the table?

Answers

Answer:i think b

hope this helps

Step-by-step explanation:

The width of the rectangular prism is W = 4 1/2 inches

What is the volume of a prism?

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

Let the volume of the prism be V = 50 5/8 inches³

Now , the length of the prism is L = 5 inches

And , the height of the prism be H = 2 1/4 inches

Let the width of the prism be W = W

where Volume of Prism = B x h = L x W x H

On simplifying , we get

50 5/8 inches³ = 5 x 2 1/4 x ( W )

50.625 = 11.25W

Divide by 11.25 on both sides , we get

W = 4.5 inches

Hence , the width of the rectangular prism is W = 4.5 inches

Answers

Answer:

Reflection: A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

Dialation: A"(10, 6)

                B" (4, 6)

                C" (4, 2)

                D" (10, 2)          

Step-by-step explanation:

A(−5,3),B(−2,3),C(−2,1),D(−5,1)

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

                   A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

To dialate by a scale factor of 2 you multiple everything by 2 and you should get:           A"(10, 6)

               B" (4, 6)

               C" (4, 2)

                D" (10, 2)

The figure can be composed of different shapes.

What shapes can the figure be decomposed into to find the area? What is the area?
A. one triangle and one square; 24 square feet
B. one triangle and one rectangle; 30 square feet
C. two triangles and one square; 36 square feet
D. two triangles and one rectangle; 42 square feet

Answers

the answer is a because if you split the shape you would get one triangle and one square or rectangle

The figure can be composed in to one triangle and one rectangle and the area is 30 square feet.

What is Area?

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given is a figure.

We can divide the figure in to one triangle and one rectangle by drawing a vertical line.

Area of a rectangle = Length × Width

Here, length = 8 feet and width = 3 feet

Area of rectangle = 8 × 3 = 24 feet²

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

Base = 12 - 8 = 4 feet and height = 3 feet

Area of triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 6 feet²

Total area = 24 feet² + 6 feet² = 30 feet²

Hence the area is 30 feet².

Answers

Answer:

C

Step-by-step explanation:

If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.

A 4 + 3 ≥ 1   True, it's greater, but it can't be equal to.

B 3(4) ≥ 1     It's greater once again, can't be equal to.

C 4 - 3 ≥ 1     If x can also be greater than 4, then it works both ways. Equal and greater than.

Number 8 is A. 4, when a letter/variable is right beside number you multiply it. So since n=4, the equation should be 7 x 4 + 14= 42...also keep in mind the answer has to be less than 56

A baseball coach order hats for his team. Each hat cost $10. The shipping charger is $6. The total cost of the order must be less than $125. Which inequality can be used to solve?

Answers

The answer should be:

10h + 6 < 125

Answer:

10x + 6 < 125

Step-by-step explanation:

Hi,

10x is the cost per hat. 6 is the charging fee. 125 is the total cost of the order. We put x because we don't know how many hats they're going to buy. 6 is the amount they pay no matter what. And < is used because the total cost has to be less than 125, not less than or equal to, but LESS than.

Answer:

R=110 degrees

B=110 degrees

Step-by-step explanation:

R and B are the same angle, we minused the mesure of G and since angle O is same as the other angle we multiplied 60 by two and then added 20 which gave us 140

360-140=R+B

220=R=B

110=R

110=B

Answer:

m<R = 120 degrees, m<B = 100 degrees

Step-by-step explanation:

1. i found the blue line and the angle of any line is 180 degrees

2. since angle O is 60 you have to subtract it from 180 -60 = 120 = m<R.

3. this one is more complicated you have to subtract angle O and angle G which is 20 degrees so you add 20 + 60 = 80 and then you take the sum and subtract it from 180: 180 - 80 = 100
