Answer:
x = 15, Angles are both 130!
Step-by-step explanation:
Since this is an example of Alternate Exterior Angles, you could set these equal to eachother!
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 5 = 130
Answer:
Since this is an example of Alternate Exterior Angles, you could set these equal to each other! its 125
Step-by-step explanation:
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 10 = 125

a. 80

c. 130
d. 53
Answers
A.80
B.125
C.130
D.53
The predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.
What is a scatter plot?A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed.
To get the predicted value to the scatter plot at x=40, substitute the value of x as 40 in the given function of the trend line. Therefore, the value will be,
[tex]y = 3x+10\\\\y = 3(40)+10\\\\y=130[/tex]
Hence, the predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.

B.

C.

D.

Answers
Answer:
C. The perimeter of the kiteStep-by-step explanation:
Answer A is not correct because if the kite moves both right and up, the x and y coordinates will change
Answer B is the same as answer A. The kite moved so the coordinates will change.
Answer D is also the same. If the kite moves both on the x and y axis, any angle and distance will change.
Answer C is correct. Since C does not rely on the coordinates, it will always be the same. The position of a shape does not change it´s perimeter.

Help please show work too
Answers
Answer:
B
Step-by-step explanation:
I am not sure what your teacher wants but I guess you can say the following:
at n = 1, the cost is 4 dollars.
at n = 2, the cost is 8 dollars.
This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.
For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.

a skydiver jumps out from the plane at 10,000 feet above the ground. the skydiver decends at a rate of 175 feet per seconds. how high in the air is the skydiver when he opens his parachute after 25 seconds?
Answers
Answer:
5625 feet
I hope it's helps you
Answer:
5625 feets
Step-by-step explanation:
Rate(feet/seconds) = height(feets)/time(seconds)
175 = x/25
x = 4375
After the skydiver opens his parachute the height reduces
Initial height – reduced height
10000 – 4375
= 5625 feets

The probability of spinning an odd number, not flipping heads, then not spinning a 6 is
__
Answers
Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:
[tex]p = \frac{20}{81} = 24.69\%[/tex]
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
There are 5 odd numbers in the spinner, out of 9, hence the probability of spinner an odd number is 5/9.The coin is fair, hence the probability of flipping tails = not heads is of 1/2.Out of the 9 numbers in the spinner, only one is six, hence the probability of not spinning a 6 is of 8/9.Then, the probability of the compound event is:
[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]

Skye made a deposit of $625 into an account that earns 4% simple interest for 6 years. How much did Skye earn in interest at the end of 6 years?
Answers
Answer:
She will earn 150$
Step-by-step explanation:
4% = 0.04
0.04 x $625 = 25
Now we divide 25 by the number of years, which is 6.
6 x 25 = 150$
Therefore, Skye earns 150$ from interest over the course of 6 years.

The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.
What is a Histogram?An histogram is a graphical representation of a data distribution, which uses bars or bins to represent the frequency of the data distribution that are in intervals.
Similarly, in dot plot the total number of dots tells us the total number of observations of the values of that thing we did.
The Stem and leaf plot is to show the data distribution while retaining its uniqueness which shows the raw values by retaining the original data,
The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.
