For two figures to be considered congruent, their corresponding sides and angles must all be the same. Congruence can occur in any geometric figures, from simple line segments to complicated shapes with many sides and angles. Here’s another way to think about congruence: if you cut two figures out of paper, you could place one cutout on top of the other cutout and it would disappear. Consider that geometric figures are made up of an infinite number of points. When superimposed on top of each other, all of the points in one figure would match up with all of the points in the other figure.
According to the passage, which of the following is not true?
A
Paper cutouts can be used to determine congruence.
B
Congruent figures have exactly the same size and shape.
C
Congruence only happens in three- or four-sided figures.
D
Two octagons can be congruent if their corresponding sides and angles match up.
Answer:
Anwer is C

A pom-pom manufacturer makes each of its pom-poms with 35% white strands (w), 25% blue strands (b), and 40% red strands (r). If each pom-pom has a total of 80 strands, how many of strands of each color are needed to make a pair of pom-poms? In this activity, you’ll work through this pom-pom problem step by step.
Part A
Write a proportion for the number of strands in each color to find how many strands are needed to make one pom-pom.
white strands: w/80=?/?blue strands:b/80=?/?red strands: r/80=?/?
Answer:
32 red
28 white
20 blue
Step-by-step explanation:
.40 x 80 = 32 red
.35 x 80 = 28 white
.25 x 80 = 20 blue
The totals have to equal the total number of strands.
Answer:
white: w/80 = 35/100
blue: b/80 = 25/100
red: r/80 = 40/100

1. If you measure one hundred centimeters is the distance more or less than one kilometer?
a) 100 centimeters is equl to 1 kilometer
b)100 centimeters is more than 1 kilometer
c)100 centimeters is less than 1 kilometer
Answer:
b is wrong it is c
hope it helped
Step-by-step explanation:
The distance is less than one kilometer, because one kilometer is equal to 100000 centimeters.
What is kilometer?A kilometer is a unit of the metric system that is used to measure length or distance. It is mainly used to express a distance as a unit of the International System of Units (SI units).
1 kilometer = 1000 meters.
1 meter = 100 centimeters
1 kilometer = 100000 centimeters
Hence, the distance is less than one kilometer.

An elevator can hold less than 2700 pounds of extra weight. If an average person weighs 150 pounds, what is the maximum number of people (p) that can be on the elevator at one time?
(A) p ≤ 18
(B) p > 18
(C) p < 18
(D) p ≥ 18
Answer:
(A) p ≤ 18
Step-by-step explanation:
p = people obviously
If you divide 2700 and 150 you get 18
2700/150 = 18
So now this is where you have to think a little, if 18 people get on an elevator then they are at maximum weight capacity. But if 17 people or less get on then they don't exceed the weight limit for therefore p can be less than or equal to 18, which is why this sign (≤) is there, the little line under the less then sign means it can be less than or equal to.

A biker’s speed is 1.5 times faster than a walker’s speed. They start moving simultaneously in the same direction from the same point and, after 1.5 hours, the distance between them is 12.5 miles. What are their speeds?
Answer: Speed of walker and biker will be 16.67 miles per hour and 25 miles per hour respectively.
Step-by-Step explanation:
Leave the speed of a walker alone x
Let the speed of a biker be 1.5x
They are moving a similar way,
thus, their Relative speed will be
1.5x - x =0.5x
Time taken = 1.5 hours
Separation between them = 12.5 miles
As we probably am aware the equation for "Distance":
*Picture attached*
Consequently, the Speed of the walker be 16.67 miles every hour
Speed of biker be
1.5 times 16.67=25 miles per houe
The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.
What is speed?Speed is the distance that a particle or body travels in one hour. It has a scalar value. It is the time-to-distance ratio.
We know that the speed formula
Speed = Distance/Time
A biker’s speed is 1.5 times faster than a walker’s speed.
Let y be the speed of the biker and x be the speed of the walker. Then the equation is given as,
y = 1.5x
They begin going simultaneously from the same location in the same direction, and after 1.5 hours, there are 12.5 miles separating them.
y - x = 12.5 / 1.5
1.5x - x = 25/3
0.5x = 25/3
x = 16.67 miles per hour
Then the speed of the biker will be given as,
y = 1.5 (16.67)
y = 25 miles per hour
The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.

Your test scores in one class are 80 and 88. What possible scores can you earn on your next test to have a test average between 84 and 89, inclusive?
Answer:
The average of your two scores to date is 84. You need the average of these two tests plus the next test to be between 84 and 89.
So, you need to solve for x, where 2/384 + 1/3x = 84. This will give you the lower end of your next test.
And you need to solve for y, where 2/384 + 1/3y= 89. This will give you the higher end of your next test.
The reason for the 2/3 in front of the 84 is because there are two tests there, and the reason for 1/3 in front of the unknowns is because that is just one test. Averages need to be weighted by number of observations.
I won't go through the algebra here, but the answers will be 84 and 99.
Step-by-step explanation:
Answer:
84 to 99
Step-by-step explanation:
If the goal for your average is 84, then your test scores total ...
(80-84) +(88-84) = -4 +4 = 0
relative to your desired average. This means your minimum score on the next test will need to be 84 -0 = 84.
__
If the goal for your average is 89, then your test scores total ...
(80-89) +(88-89) = -9 -1 = -10
relative to your desired average. This means your maximum score on the next test will need to be 89 -(-10) = 99.
To ensure a test average between 84 and 89, your next test score must be between 84 and 99.
