Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
(A) The scale factor of the dilation that transforms Triangle PQR to Triangle P'Q'R' is 1/4
(B) Coordinates of Δ P"Q"R"
P" (-1,0)
Q"(0,-1)
R"(2,-1)
(C) Triangles PQR and P"Q"R" are not congruent.
Given
ΔPQR is transformed into ΔP'Q'R'
Coordinates of P, Q, R are
P (4,0),
Q(0,-4)
R(-8,-4)
Coordinates of P'Q'R' are
P'(1,0)
Q'(0,-1)
R'(-2,-1)
(A) By Distance formula we can find the distance between P Q and P'Q'
Distance formula =
Where D = Distance between two points
from distance formula we can write that
PQ =
Similarly
P'Q'=
PQ /P'Q' = 4
hence the scale factor of dilation is 1/4 (Compression)
(B )The Coordinates of Reflection about y axis can be written for a point
So the Coordinated of Δ P"Q"R" can be written as
P" (-1,0)
Q"(0,-1)
R"(2,-1)
(C) ΔPQR and ΔP"Q"R" are similar triangles but they are not congruent because their sides are not equal in size.
Which expression is equivalent to 6 times the sum of 8 and a number, n?
Answer:
6(8 + n)
Step-by-step explanation:
8. Explain why 30+1 = 6 is the same as 30 -/-/--/-X-X = 0. What is
the value of x in this example?
Answer:
5
Step-by-step explanation:
5 because of two ways one you could do 6*what is 30. Or you could do repeated addition 30=5+5+5+5+5+5. But when you do 30=5-5-5-5-5-5. You are doing repeated subtraction which is equivalent to 30-5*6= 0.

5 red marbles, 6 green, 2 blue. what is the probability of not picking blue
Answer:
11/13
Step-by-step explanation:
this is because if you add all the possibilities, it = 13 and since you WANT TO FIND THE PROBABILITY OF NOT PICKING BLUE minus 13 by 2 which is 11.

The answer is B
answer:
c.962.51 in^3
step-by-step explanation:
so first we have to find the radius
in order to find the radius we divide 12 1/4÷2
which equals 6.125, now we have our radius
now we need to set up the formula
v=4/3πr^3
v=4/3π6.125^3
v=962.51
to check your work you can goo-gle volume of a sphere **you should get the same answer**
good luck :)
hopefully, this helps
have a nice day !!

Answer: im not absolutely sure, but i think A
I need help with this (giving brainliest)
Answer:
R=110 degrees
B=110 degrees
Step-by-step explanation:
R and B are the same angle, we minused the mesure of G and since angle O is same as the other angle we multiplied 60 by two and then added 20 which gave us 140
360-140=R+B
220=R=B
110=R
110=B
Answer:
m<R = 120 degrees, m<B = 100 degrees
Step-by-step explanation:
1. i found the blue line and the angle of any line is 180 degrees
2. since angle O is 60 you have to subtract it from 180 -60 = 120 = m<R.
3. this one is more complicated you have to subtract angle O and angle G which is 20 degrees so you add 20 + 60 = 80 and then you take the sum and subtract it from 180: 180 - 80 = 100

What is statistical?The statistical is an arithmetic mean process, in that it adds up all numbers in a data set, and then divides the total by number of data points.
What is not statistical?Questions that are answered with a single data point are not statistical questions because there is no variability in the data used to answer the question.
According to the given question
1). Not statistical. This question is answered by a single number. It is not not answered by collecting data that vary.
2). Statistical. This question would be answered by collecting data ,and there would be variability in the data.
3). Not Statistical. This question is answered by single number. It is not answered by collecting data.
4). Not statistical. This question is answered by a single number. It is not answered by collecting data that vary.
5). Statistical. This answer would be answered by collecting data because we have to collect the data for each student that how many TV shows they watch.

Answer:
39
Step-by-step explanation:
Square Area
8-3 to get the right side of the square which equals 5. So the square is 5*6=30
Triangle Area
To get the area of a triangle the formula is a=b*h*1/2, so base is 3 and height is 3, we would do 3*3*1/2 which equals 4.5
but you have 2 triangles so multiply 4.5*2 and that's 9.
Conclusion
So, 30+9=39
