Answer 1

Answer:

[tex]A_s=179 \ yd[/tex]

Step-by-step explanation:

Area of Circle can be calculated using following formula

[tex]A=\pi r^{2}[/tex]

Where r is radius of circle

Area of outer circle (r=11 yd)

[tex]A_1=\pi (11)^{2}\\A_1=379.94 \ yd[/tex]

Area of inner circle (r=8 yd)

[tex]A_2=\pi (8)^{2}\\A_2=200.96 \ yd[/tex]

Area of shaded region

[tex]A_s=A_1-A_2[/tex]

[tex]A_s=379.94-200.96\\A_s=179 \ yd[/tex]

Answer:

wx=51

Step-by-step explanation:

8a-5=5a+16

3a=21

a=7

8(7)-5=wx

wx=51

Answer:

The length is 56

Step-by-step explanation:

First, since WX and ZY are the same length, set them equal to each other and solve for a:

8a-5 = 5a+16

8a = 5a + 21

3a = 21

a = 7

Now, you can plug in 7 for a in the original equation and get:

8a-5

8(7)-5

56-5

51 is your final answer!

What happens to the mean of the data set {10, 2, 8, 9, 5, 2, 6} if the number 12 is added to the data set? A. The mean increases by 2. B. The mean increases by 12. C. The mean increases by 0.75. D. The mean increases by 1.75.

Answers

Answer:

C. The mean increases by 0.75.

Step-by-step explanation:

The mean of a data set is given by the sum of all its values, divided by the number of values.

Data set {10, 2, 8, 9, 5, 2, 6}

7 values

Sum: 10 + 2 + 8 + 9 + 5 + 2 + 6 = 42

Mean: 42/7 = 6

Adding number 12 to the data set

Now we have 8 values

The sum is 42 + 12 = 54

The mean is 54/8 = 6.75

This means that the mean increases by 0.75.

C. 7.5

Here a easy one tooooooooooooo

Answers

Remember:
A triangle is always 180 degrees and so is a straight line so 360 degrees in total:

1) Add 92 and 123 which equals 215
Then 360 subtracted by 215 is 145

Answer: 145

2) add 100 and 25= 125
360-125= 235
Answer: 235 degrees

Answer: See explanation

Step-by-step explanation:

1.) There's an angle supplementary to m∠123°, that angle is y

y and m∠123° are supplementary since they're linear pairs

y + 123 = 180

Subtract both sides by 123

y = 57°

Now we know at least two angles of the triangle, x + y + m∠92° has to be 180° because they form a triangle.

x + y + m∠92° = 180°

x + 57 + 92 = 180

x + 149 = 180

Subtract both sides by 149

x = 31°

2.) We have to figure out the missing angle in the triangle, that missing angle is once again, y.

y + 100 + 25 = 180

y + 125 = 180

y = 55°

x and y are supplementary angles because they form a straight line

x + y = 180°

x + 55 = 180

Subtract both sides by 55

x = 125°

I took the test.

Hope this helpssss

Answer:

Only statements 1 and 5 are true.

Step-by-step explanation:

Statement 1: True

In intervals 1 and 4, the graph slopes down to the right. That shows a decreasing function.

Interval 2 goes up to the right. That is an increasing function, not a constant functions.

Statement 3: False

The graph increases in interval 2 but decreases in interval 4.

Statement 4: False

The graph has intervals of increase, decrease, and constant value.

Statement 5: True

Interval 3 is horizontal, so it is constant.

Answer:

Statements 1 and 5 are true. All others are false.
