For Questions 7 - 10, Determine Whether The Angle Of Rotation Is 90,180'or 270'. Each Rotation Is Clockwise

Answers

Answer 1

Answer:

7/ 180 degree

8/ 90 degree

9/ 270 degree

10/ 180 degree

Step-by-step explanation:

7/ Each square box is 90 degrees, and we see that the square rotated over 2 boxes, so it is 180 degrees clockwise.

8/ We see that the triangle rotated 90 degrees clockwise.

9/ We see that the triangles rotate over three boxes, which is 270 degrees clockwise.

10/ We see that the triangles rotate over 2 boxes, which is 180 degrees clockwise.

Answer 2

Answer:

7) 180°

8) 90°

9) 270°

10) 180°

Step-by-step explanation:

7)

The notation for rotating 180 degrees clockwise about the origin is (the degrees symbol was omitted): [tex]R_{-180, O} (x,y) - > (-x,-y)[/tex]

This means that when you rotate 180 degrees clockwise about the origin, the coordinates of the figure become their opposite.

C(2,-1) -> C'(-2,1)

N(4,-2) -> N'(-4,2)

W(3,-4) -> W'(-3,4)

Y(1,-3) -> (-1,3)

..............fun fact: rotating 180 degrees clockwise is the same as rotating 180 degrees counterclockwise

8)

The notation for rotating 90 degrees clockwise about the origin is (the degrees symbol was omitted): [tex]R_{-90, O} (x,y) - > (y,-x)[/tex]

This means that when you rotate 90 degrees clockwise about the origin, the x and y coordinates flip, and the x coordinate becomes its opposite.

B(-4,-2) -> B'(-2,4)

E(-1,-5) -> E'(-5,1)

I(0,-1) -> I'(-1,0)

..............fun fact: rotating 90 degrees clockwise is the same as rotating 270 degrees counterclockwise

9) The notation for rotating 270 degrees clockwise about the origin is (the degrees symbol was omitted): [tex]R_{-270, O} (x,y) - > (-y,x)[/tex]

This means that when you rotate 270 degrees clockwise about the origin, the x and y coordinates flip, and the y coordinate becomes its opposite.

G(-4,2) -> G'(-2,-4)

Z(-1,5) -> Z'(-5,-1)

T(0,2) -> T'(-2,0)

..............fun fact: rotating 270 degrees clockwise is the same as rotating 90 degrees counterclockwise

10) The notation for rotating 180 degrees clockwise about the origin is (the degrees symbol was omitted): [tex]R_{180,O} (x,y) - > (-x,-y)[/tex]

This means that when you rotation 180 degrees clockwise about the origin, the coordinates of the figure become their opposite.

B(-3,-5) -> B'(3,5)

G(-4,0) -> G'(4,0)

C(-5,-4) -> C'(5,4)

..............fun fact: rotation 180 degrees clockwise is the same as rotation 180 degrees counterclockwise

Step-by-step explanation:

Question 9 (1 point)

In the middle school PTA there is a total of 47 men and women. The number of women the PTA is 2 more than four times the number of men. How many women are in the

PTA?

Let the number of men = x

Let the number of women = y

x + y = 47

y = 2 + 4x

We substitute

x + 2 + 4x = 47

Collect like terms

5x = 47 - 2

5x = 45

x = 45/5 = 9

y = 2 + 4x

y = 2 + 4 × 9

y = 2 + 36

y = 38

Therefore, the number of women = y = 38 women

What is the area of this rectangle? A rectangle that is partitioned into two rectangles. The first rectangle has a measurement of five meters along the top, and a measurement of eight meters along the side. The second rectangle has a measurement of five meters along the top, and a measurment of eight meters along the side. 50 square meters 60 square meters 70 square meters 80 square meters

Answers

Answer:

80 square meters

Step-by-step explanation:

A rectangle that is partitioned into two rectangles; rectangle A and rectangle B

Rectangle A:

Top = 5 meters

Side = 8 meters

Area of rectangle A = length × width

= 5 meters × 8 meters

= 40 meters ²

Rectangle B:

Top = 5 meters

Side = 8 meters

Area of rectangle B = length × width

= 5 meters × 8 meters

= 40 meters ²

Total area of the partitioned rectangle = area of rectangle A + area of rectangle B

= 40 meters ² + 40 meters ²

= 80 meters ²

To amend a​ country's constitution, 5 6 of the 52 states in that country must approve the amendment. If 44 states approve an​ amendment, will the constitution be​ amended

Answers

Answer: Yes. It will be amended

Step-by-step explanation:

Since 5/6 of the 52 states in a country must approve the amendment before the country's constitution is amended, then the number of states that must approve it will be:

= 5/6 × 52

= 43.33

= 43 approximately

Since 44 states approve an​ amendment, the constitution be​ amended since it's more than 5/6 of the 52 states.

Answer:

So I would say your answer is..............A

Step-by-step explanation:

For most places, global warming will result in more frequent hot days and fewer cool days, with the greatest warming occurring over land. Longer, more intense heat waves will become more common. Storms, floods, and droughts will generally be more severe as precipitation patterns change

Also, A is correct because lets say you put an ice cube in the sun...okay well if it keeps getting hotter and hotter multiply ice cubes into ice caps. Well same thing will happen. It will melt causeing water from the ice caps. Which will result into more water. Which will cause water to go above sea level!

You are framing a picture with a frame of equal width on each side.

a. Write a polynomial that represents the area of the picture including the frame

b. Find the area of the picture including the frame when the width of the frame is 2 inches

Answers

Answer:

Part A)

The polynomial is:

[tex]A=4(x+8)(x+10)[/tex]

Or, expanded:

[tex]A=4x^2+72x+320[/tex]

Part B)

When the width of the frame is two inches, the area of the picture including the frame is 480 square inches.

Step-by-step explanation:

Part A)

For solely the picture, the width is 16 inches, and the length is 20 inches.

If we include the width of the frame, then we will have to add x to both sides of the 16 inches. Then the new width will be (16 + 2x) inches.

Likewise, the new length will be (20 + 2x) inches.

The area of a rectangle is given by its width multiplied by its length. Then the polynomial that represents the area will be:

[tex]A=(16+2x)(20+2x)[/tex]

To simplify calculations, we can factor out a two from both factors. Thus:

[tex]A=2(8+x)\cdot 2(10+x)=4(x+8)(x+10)[/tex]

Expanded, this will be:

[tex]A=4(x^2+18x+80)=4x^2+72x+320[/tex]

Part B)

When the width of the frame is two, x = 2. Then the area is:

[tex]A=4(2+8)(2+10)=4(10)(12)=40(12)=480\text{ inches}^2[/tex]

The area of the picture including the frame will be 480 square inches.

24f2+11

Answers

Answer:

24t^2 + 11

Step-by-step explanation:

There is a lot left out of this question. If you are allowed rational numbers, a common factor could be 24.

24(t^2 + 11/24) is one possibility.

I think what you mean is there an integer that is a common factor. There is not.

So the answer is 24t^2 + 11

There is one more thing that needs to be clarified. Can you give t a value? If you can, then t = 11

the common factor would be

11(24 * 11 + 1)
