ppppp)is dilated from the origin by scale factor r to the world
triangle A' B' C' is the result of dilating ABC about point C by a scale factor of two. Determine whether each claim about the properties of A' B' C' and ABC is true or false
True because all properties are preserved under dilation from triangle ABC to A'B'C'.
We have given a triangle ABC is dilated by a factor of 2/3 , result triangle A'B'C'
We have to determine after dilation, the properties of triangle ABC and A'B'C' is true or false.
What is the transformation?A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.
Dilation of a triangle are results in either decreases or increases in the corresponding length of the triangle, it depends on by which scale factor triangle is dilated ,and dilation does not affect the angle measures of the triangle.
here scale factor is 2/3 so the corresponding sides of the triangle A'B'C' decreases.
So, the dilation of the triangle is not congruent but similar to the original triangle ABC
Therefore, the basic properties of triangles are preserved under the dilation of triangle by a scale factor.

Answer:
30 y
Step-by-step explanation:
We need to multiply 5 by 4y and 5 by 2 y
20y + 10y = 30y
Answer:
30 y
Step-by-step explanation:
You are supposed to distribute(multiply) the 5 with 4y+2y inside the parentheses. Just multiply the 4y by 5 to get 20y and then 2 y with 5 to get 10 y. Your answer should be come out to be 20y + 10y. Since they both use the same variable (y), add them together to get 30y

The original price of a
42-inch TV is $399. An
electronics store is
offering the TV for
15% off of the original
price plus a $25
discount. How much
will the TV cost after
both the sale and
discount?
A) $314.15
B) $40.00
C) $326.85
D) $359.00
PLEASE HELP
Answer:
$314.15 (A)
Step-by-step explanation:
We start by subtracting the 15% discount. 15% can be represented by 0.15, and 100% can be represented by 1. So therefore, the new price of the TV will be 1-0.15 = 0.85 of the original price using just the 15% discount. Therefore, 0.85 x 399 = $339.15. We then take this number and subtract another $25 to get $314.15

Jackson is interested in the number of memories people can recall. He knows that the number of memories recalled is normally distributed in the general population, with a population mean of 30 and a population standard deviation of 5. What is the probability that Jackson randomly selects a person from this population who recalls between 26 and 29 memories
Answer:
0.2088 = 20.88% probability that Jackson randomly selects a person from this population who recalls between 26 and 29 memories.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Population mean of 30 and a population standard deviation of 5.
This means that [tex]\mu = 30, \sigma = 5[/tex]
What is the probability that Jackson randomly selects a person from this population who recalls between 26 and 29 memories?
This is the pvalue of Z when X = 29 subtracted by the pvalue of Z when X = 26. So
X = 29
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{29 - 30}{5}[/tex]
[tex]Z = -0.2[/tex]
[tex]Z = -0.2[/tex] has a pvalue of 0.4207
X = 26
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{26 - 30}{5}[/tex]
[tex]Z = -0.8[/tex]
[tex]Z = -0.8[/tex] has a pvalue of 0.2119
0.4207 - 0.2119 = 0.2088
0.2088 = 20.88% probability that Jackson randomly selects a person from this population who recalls between 26 and 29 memories.
There are 7 red marbles, 7 blue marbles, 7 yellow marbles, and 7 green marbles in a bag. If a person randomly selects 1 marble from the bag, what is the probability that the person selects a blue marble?
Total marbles: 7 + 7 + 7 + 7 = 28
There is a total of 28 marbles. 7 are blue.
The probability is the number of blue/ total marbles = 7/28 which reduces to 1/4
The probability is 1/4
Answer:
have a good day/night may i please have a branllist
Step-by-step explanation:
1/3
There is 21 marbles and if you divided by 3 it gets 7.
7/21 is equal to 1/3
Therefore the possibility of picking a blue marble is 1/3.
there are an equal amount of all three colors of marbles in the bag, so the probability of selecting a blue marble is just 1/3.

The wholesale price of an X-BOX-X is $400.00 .It was then marked up 30% and sold online. What is the online price?
Answer:
$520
Step-by-step explanation:
1% of x is x times 0.01.
that means 10%of x is x times 0.1.
400 times 0.1 is 40.
40 is 10% of 400.
it was marked up by 30% so we need to times by 3.
40 times 3 is 120.
it was marked up so its addition.
400+120=520

can someone pls help me i’m stressed out over this. all you have to do is find the area of the shaded part, thank you sm <3
Answer:
88.86
Step-by-step explanation:
Okay, first find the area of the circle (πr^2)
The diameter of the circle is 14, however we need the radius. Simply divide the diameter by two.
[tex]\pi 7^{2}[/tex]
3.14*49 =153.86
Next, we find the area of the rectangle (bh)
13*5 =65
Subtract the rectangle from the circle.
153.86-65 =88.86
Hope this helps you :)

Does the volume of a cone increase more when you double the height of the original or when you double its radius? Explain why.
Answer:
When you double it's radius
Step-by-step explanation:
Volume of cone = 1/3(π)(r²)h
the height is a constant proportion but the radius is squared in the calculation of the base area.
Doubling the height would double the volume. Doubling the radius would more than double the volume.
Example:
a height of 4 to a height of 8 would double the volume. (the base would not change)
a radius of 4 to a radius of 8 would triple the volume. ( the base area would go from 16π to 64π)

find the missing side lengths
Answer:
Step-by-step explanation:
first use tan Ф = opp /adj to find x tan(30) = √3 / 3
then use sin Ф = opp / hyp to find y sin(30) = 1/2
tan(30) = (√3) / 3 = x / 48
x = (48√3) / 3
x = 16√3
sin(30) = 1/2 = x / y
y = x / (1/2)
y = 2x x = 16√3
y = 2[16√3]
y = 32√3
check using a² + b² = c²
x² + 48² = y²
(16√3)² + 48² = (32√3)²
256 · 3 + 2304 = 1024 · 3
768 + 2304 = 3072
3072 = 3072
