Mathematics Middle School

In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.

A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40-degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y. (5 points)

Answers

Answer 1

60° + 70° + y° = 180°

130° + y° = 180° ~Subtract 130° from both sides

y° =50°

y=x because they are both vertical angles

x° = 50°

Answer 2

Answer:

40 + 50 + y = 180

90 + y = 180

90 - 90 = 0

180 - 90 = 90

y = 90

Triangle ABC is shown. A is at negative 2, 1. B is at negative 1, 4. C is at negative 4, 5. If triangle ABC is reflected over the y‐axis, reflected over the x‐axis, and rotated 180 degrees, where will point A' lie? (−1, 2) (−2, 1) (1, −2) (2, −1)

Answers

Answer:

B (-2,1)

Step-by-step explanation:

When you reflect over x axis the coordinates go from -2,1 to 2,1. When we rotate it 180, they go from 2,1 to -2,1. Point A will be at the same spot

plz mark brainliest

Point A' will lie at (b) (-2,1) after the transformation.

The coordinates of the triangle are given as:

[tex]A = (-2,1)[/tex]

[tex]B = (-1,4)[/tex]

[tex]C = (-4,5)[/tex]

The rule of reflection over the y-axis is:

[tex](x,y) \to (-x,y)[/tex]

So, the new coordinate of A is:

[tex]A =(2,1)[/tex]

The rule of reflection over the x-axis is:

[tex](x,y) \to (x,-y)[/tex]

So, the new coordinate of A is:

[tex]A =(2,-1)[/tex]

The rule of 180 degrees rotation is:

[tex](x,y) \to (-x,-y)[/tex]

So, the new coordinate of A is:

[tex]A = (-2,1)[/tex]

Hence, point A' will lie at (b) (-2,1)

answer to 4. (225x72)/1000000, 225 thousandths × 72 hundredths

Step-by-step explanation:

first you have to find out that 0.225 x 0.72 = 0.162

then check to see if the other options equal the same

2.25 x 7.2 = 16.2 so it dosen't match

(225x72)/1000000 = 0.162 so it dose match

225 × 72 × 0.001=16.2 so it dosen't match

225 thousandths × 72 hundredths= 0.162 so it dose match

Answer:

D.) 38 cm²

Step-by-step explanation:

apologies if this isn't correct but I hope it is, anyway have a good day/night!

the area of the figure is 38.28cm².

The area of the shape is the sum of the area of the semicircle, a rectangle, and a right triangle.

Area of a semicircle = [tex]\frac{1}{2}[/tex]πr²

[tex]\frac{1}{2}[/tex]x 3.14 x (4/2)² = 6.28 cm²

Area of the rectangle = length x width

6 x 4 = 24 cm²

Area of the right triangle = [tex]\frac{1}{2}[/tex]x base x height

[tex]\frac{1}{2}[/tex]x (10 - 6) x 4 = 8cm²

Sum of the areas = 8 + 24 + 6.28 = 38.28cm²

If the ratio of students with green shirts to total students in a class is 3 to 8, and are 12 students wearing green shirts, how many are there without green shirts?

Answers

Answer:

Step-by-step explanation:

GS:S

(GreenShirt:Students)

3:8

12÷3=4

1 Part=4

8×4=32

32 Students didn't have a green shirt

I think 7 because you know 3 to 8 and 12 students if you multiply 3x12 then divide by8 you get 4.5 which if we round 5 that’s how many are wearing green so now 12-5 that how you get 7 so 7 are not wearing green
