Copy the proof on paper, mark the givens in the diagram, and fill in the blanks to complete the proof.
This is the actual answer:
The missing values are PU, PU ≅ PU, UR, PR, and Triangle RUP by applying Corresponding parts of congruent triangles are congruent.
What is congruence in the triangles?The measurements of the sides and angles of two or more triangles determine their congruence. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of corresponding sides and angles of two triangles are equal, they are said to be congruent.
We have:
As we can see in the diagram,
First, we will draw PU
PU is the common side for both the triangles
PU ≅ PU (reflexive property)
UO ≅ UR (given)
PO ≅ PR (given)
By the property of SIde-Side-Side
The triangle OUP ≅ Triangle RUP
By Corresponding parts of congruent triangles are congruent:
Angle O ≅ Angle R (proved)
Thus, the missing values are PU, PU ≅ PU, UR, PR, and Triangle RUP by applying Corresponding parts of congruent triangles are congruent.

given a storm has a destruction area in the shape of a square, give the total area affected if the side lengths of the square were 315.2
Answer:
to find area, multiply the two sides together. since it tells us that this is a square we can assume both sides are the same length (315.2). multiply 315.2 and 315.2, and you get 99,351.04.

Step-by-step explanation:
Which pair of equations could not be used to solve the following equations for x and y?
4 + 2 = 22
−2 + 2 = −8
A.4 + 2 = 22 B. 12 + 6 = 66 C. 4 + 2 = 22 D. 8 + 4 = 44
2 − 2 = 8 6 − 6 = 24 -4x + 4y =-16 -8x + 8y = -8

We can multiply both by 8
So, 8x and -24
So its correct
2We multiply 8 by both
So, we have 8x-192
So, no
FIrst, we can do 9 and apply it to both x and -3
So, 9x-27-x+3
So, 8x-24
SO, yes
4
5+3*x = 8x
So, 8x-24
So yes

Answer:
Step-by-step explanation:
So its difficult to show
Y= X-6 so what ever x is, y is six less than that so
X= -4 Y= -10
X= 0 Y=-4
X=4 Y=0
X=8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that
X=-4 Y= -5
X=0 Y= -2
X=4 Y=1
X= 8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= -2
Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.
Y= 2+ 1/4x so whatever x is y is 1/4 of x add 2
X=-8 Y= 0
X= -4 Y = 1
X=0 Y=2
X=4 Y=3
X=8 Y=4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Do this method for 9
y = 2x -3 so whatever x is, y is 2 times that -3
y=2x +1 so whatever x is y is 2 times that +1
y= 2x so whatever x is y is 2 times that
Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them
Make sure to label each line
Hope this helps

Krystine has a weekend job advertising an upcoming play. She has two options for being paid. Option A is an hourly wage of $7.00. Option B is a 5% commission on all money made at the play. She plans to work 8 hours each day on Saturday and Sunday. Tickets are sold for $10 each, and Krystine estimates she will sell about 200 tickets. Which option gives Krystine more earnings this weeknd?
Answer: Option A
===================================================
Explanation:
If she goes with option A, then she works two days for 8 hours a day. In total she works 8+8 = 16 hours. At $7 an hour, she earns 16*7 = 112 dollars.
If she goes with option B, then she earns 5% on the total of 200*10 = 2000 dollars. So 5% of 2000 = 0.05*2000 = 100 dollars is earned.
Option A yields her $112 while option B yields $100. She earns more with option A.
Answer:
Option A with hourley wage of $7.00 per hour is best and gives her more earnings.
Step-by-step explanation:
Option A gives Kristine 16 hours times $7.00 per hour for total of $112.00
Option B gives 5% of $2000 (total commission on all money made at play) for $100
