Each pair of polygons is similar. Write a similarity statement for the polygons. Then, find the measure of x, the measures of the indicated sides, and the scale factor.
Answers
Answer:
C
Step-by-step explanation:
The similarity statement is correct. Because they are similar, AB is equal to EF, so to find x, you do x-2=2.2. Solve that and you get x=0.2

A.The speed he bikes at affects the time it take him to get to school, but it is unclear if the time increases or decreases.
B. As the average speed increases, the time he takes to get to school decreases.
C. The speed he bikes at does not affect the time it takes him to get to school.
D. As the average speed increases, so does the time he takes to get to school.
Answers
Answer:
B: As the average speed increases, the time he takes to get to school decreases.
Step-by-step explanation:
On the graph, it showed that the plotted points are decreasing as the average speed is increasing. Also, I took the test and B was the correct answer.

The observatory in the John Hancock Center in Chicago is located in the top floor, 900 feet above the ground. The express elevator travels nonstop from the ground floor to the observatory on the top floor at a rate represented by the equation y=30x, where y is the height, in feet, and x is the number of seconds.
Answers
Answer:
Step-by-step explanation:
Given the rate at which the elevator travels modeled by the expression;
y = 30x where y is the height, in feet, and x is the number of seconds.
If the observatory in the John Hancock Center in Chicago is located in the top floor, 900 feet above the ground, we can calculate the time taken to reach the top floor by substituting y = 900 into the equation and solve for x as shown;
y = 30x
900 = 30x
Rearrange
30x = 900
Divide both sides by 30
30x/30 = 900/30
x = 30
Hence it takes 30seconds for the elevator to reach the top floor

Can you help me with these angles please????
Answers
Answer:
11. ∠9 = 100°
12. ∠6 = 80°
13. ∠8 = 80°
14. ∠2 = 80°
15. ∠5 = 100°
16. ∠11 = 100°
Step-by-step explanation:
Answer:
11. 100° 12. 80° 13. 80° 14. 80° 15. 100° 16. 100°
Step-by-step explanation:
We know a straight line is 180 degrees and that m∠7 is 100 degrees.
m∠9, m∠5 and m∠11 are 100 degrees
To find m∠6, m∠8, and m∠2 we subtract 100 from 180 and get 80 degrees.
If you fill in all the degrees of the angles, you will notice a zig-zag pattern. That helps when solving these kinds of problems

-13 = r/9 + 8
Solve for r
Answers
r = -189
-13 = r/9 + 8
Subtract 8 on both sides
-21 = r/9
Multply 9 on both sides
-189 = r
Answer:
r = -189
Step-by-step explanation:
-13 = r/9 + 8
-13 - 8 = r/9
-21 = r/9
-21 × 9 = r
-189 = r

What is the equation of the line that goes through the points 2,9 and 3,1
Answers
The equation of the line that goes through the given points is y = -8x + 25.
Given the following points:
Points on the x-axis = (2, 3)Points on the y-axis = (9, 1)To determine the equation of the line that goes through the given points:
First of all, we would determine the slope of this line by using the following formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substituting the points into the formula, we have;
[tex]Slope, \;m = \frac{1 - 9}{3 - 2}\\\\Slope, \;m = \frac{-8}{1}\\\\[/tex]
Slope, m = -8
Now, we can determine the equation of the line by using this formula:
[tex]y-y_1 =m(x-x_1)\\\\y-9=-8(x-2)\\\\y-9=-8x+16\\\\y=-8x+16+9[/tex]
y = -8x + 25

Answer:
[tex]x = -\frac{1}{7}[/tex]
Step-by-step explanation:
2(5x + 1) - 2x = 2 - 2(3x + 1)
Use the distributive property
10x + 2 - 2x = 2 - 6x -2
Combine like terms
8x + 2 = -6x
Subtract 2 from both sides
8x = -6x - 2
Add 6x to both sides
14x = -2
Divide both sides by 14
x = -2/14 = -1/7
Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. The constant of proportionality is 42. Write an equation to represent the relationship between the number of yards of yarn Paula has and the number of hats she can knit.
