The acute angles of the right isosceles triangle are congruent. You rotate the triangle 160° counterclockwise about the origin. What is the measure of each acute angle after the rotation? What is the measure of the two congruent sides after the rotation?
Answer:
The measure of the acute angle stays the same.
the measure of the two congruent sides stays the same.
Step-by-step explanation:
Congruent, in Maths / Geometry, means identical in form; coinciding exactly when superimposed.
Meaning everything except the rotation stays the same.

A survey of a group of seventh-graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results.
Based on the shape of the two-dot plots, which statements correctly compare them? Select three choices.
The center of the data for students has a value less than that of the center of the data for teachers.
The center of the data is to the right of the dot plot for both teachers and students.
There is a greater variation in the data for teachers than for students.
Both sets of data cluster around 2.
The same number of teachers as students were surveyed.
Answer:
More students cluster around area 2

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.
Studied: 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 83
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89
Part 1: Calculate the mean of the group that did not study, rounded to the nearest tenth.
Part 2: Calculate the mean absolute deviation of the group that did not study, rounded to the nearest tenth.
Part 3: How many of the scores (from the group that did not study) are more than two mean absolute deviations from the mean?
Answer:
Didn't study: 76%
Mean absolute deviation: 11.2
Step-by-step explanation:
To find the mean, add all the scores from the people who didn't study and divide them by 12 (the total number of students who didn't study). You will get 76%To find the MAD, use the formula for MADTo answer the third, line them up in order. 45, 58, 65, 72, 73, 77, 82, 83, 87, 89, 90, 91. MAD is the average difference between the numbers. So, to find this answer, subtract two of the MAD's from the mean of 76%. 76-22.4 = 53.6. So, only one is more than two MAD's away from the mean of 76%.Find the area of the trapezoid

Step-by-step explanation:
So, it talks about the discount being 30% or $24 dollars. This is only part of the original price.
Where, the original price is the total price. So, the means that it is the whole price.
Just to help:
Answer - Part B: The original cost of the jeans are $80.
Step-by-step explanation:
If you find 30% of 80, then you will have to do x/80 = 30/100. Next, you will cross multiply (x times 100 and 80 times 30), which gives you 100x and 2,400. Now, you will divide both numbers by 100. You should now have x and 24. So, x = 24.
So, see? 30% of 80 is $24.
(This can also be used to show your work)
Hope this helps! :)

How is unit rate related to the linear equation?
Answer:
https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-linear-equations-functions/cc-8th-graphing-prop-rel/v/graphing-proportional-relationships-example
Step-by-step explanation:
Answer:
A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.

The Lunchroom Murder
On an otherwise uneventful Thursday afternoon police heard a shot inside the local bistro, Ernie’s Lunchroom. They rushed in and found the scene shown in Figure 1.4.
They identified the body as that of a prominent racketeer named Fannin. Ernie, who is both the owner and only employee, had only one fact to tell: the murderer had leaned against the wall while firing at point-blank range. The imprint of his hand is in clear view.
The police have also noticed that the cash register had just been rung up at $8.75.
This is a difficult case. Your investigative team must attempt to determine which of the people in the lunchroom killed Fannin. You will have to observe the details carefully. There is enough evidence to help you explain most of what happened.
QUESTION: Which set of footprints are Ernie’s? What is the evidence?

Solve for x
Answer:
x = 156
Step-by-step explanation:
These angles are supplementary so they add up to 180:
x - 5 + 29 = 180
x + 24 = 180
x = 156
Answer:
x = 156
Step-by-step explanation:
The line equals 180 degrees, and the angle 29 degrees is already given.
180-29 = 151
This means that the other angle must be 151 degrees.
(x - 5)°
If we replace 156 with x, we will get 151 degrees, so that means x = 156.
(156 - 5)° = 151°
