Vivek is making a perpendicular segment in the middle of segment JR.
First, he drew an arc centered at J.
Then, he used the same radius to draw an arc centered at R.
Next, he found the points where the arcs intersected.
What MUST be true?
Line J R. Point P is above the line and point N is below the line. Arcs centered at J and R go through points P and N.
CLEAR CHECK
P is the same distance from N as J is from R.
PN is equal to JR.
Any point on PN will be equidistant from J and R.
NR is half of JR.
Answers
Answer:
Step-by-step explanation:

A figure shows a triangle drawn inside a trapezoid. The area of the triangle is 445 in², and the area of the trapezoid is 2225 in². A point on the figure is randomly selected, and its location is recorded.
After 150 trials, the randomly selected point was in the triangle 48 times.
How does the experimental probability of a randomly selected point being in the triangle compare to the theoretical probability of the event?
The experimental probability of the event is
Choose... 20, 30, or 32
and the theoretical probability of the event is
Choose...20, 30, or 32
Therefore, the experimental probability is
Choose... equal to, greater than, or less than.

2) 62.5
3) GREATER THAN
Answer:

Step-by-step explanation:
Initial Deposit = $500at a 1.5% interestSo . .
500.00 ×1.5 =7.5Then . .
7.5 is for 1 year so
7.5 × 5 = 37.5Then just add 37.50 to 500
Final outcome = $537.50Answer: He will have 3750 in 5 years.
Step-by-step explanation: You need to do 500x1.5x5. 500 dollars is the amount in the account. 1.5 is the interest. 5 is the amount of years.
The dog park is 13 mile wide and 12 mile long. Shayna walks her dog, Buster, around the perimeter of the dog park two times. Explain how you determined whether Shayna and Buster walk more or less than 3 miles.
Answers
Answer:
Step-by-step explanation:
PERIMETER = 1/3 + 1/3 + 1/2 + 1/2 = 2/3 + 1 = 1 2/3 miles for 1 LAP.
For 2 LAPS, 2 x 1 2/3 = (2 x 1) + 2(2/3) = 2 + 4/3 = 2 + 1 1/3 = 3 1/3 miles
Or, 2 x 1 2/3 = 6/3 x 5/3 = 30/9 = 3 3/9 = 3 1/3 miles
Or, 2/1 x 5/3 = 10/3 = 3 1/3 miles
ANSWER: MORE THAN 3 MILES
=============================================================
Explanation:
We're given a 1/3 by 1/2 rectangle. The perimeter is:
P = 2(L+W)
P = 2(1/3+1/2)
P = 2(2/6+3/6)
P = 2(5/6)
P = 10/6
P = 5/3
The rectangle has a perimeter of 5/3 miles, which is equivalent to the mixed number of 1 & 2/3.
--------------
If Shayna and her dog walked the perimeter once, then the answer would be "less than 3 miles".
However, they walked around the park twice. We'll need to double the result.
2*(5/3) = 10/3 = 3 & 1/3
Therefore, they walked more than 3 miles.

Answers
Answer:
Put both equations into standard form (Ax+By=C).
Multiply one or both of the equations by a number so that you will have opposite coefficients on the same variable.
Add the two equations together. Add the x's, the y's, and the numbers.
Solve for the variable.
Take your answer from the last step and plug it into of the equations (pick the one that looks easiest).
Your solution will be in the form of a coordinate point (x,y).

Dave gave Heather directions on how to find where he had buried a box in his backyard. He didn’t want to make it easy for her, so he gave her complicated directions. This is what he said:
When you walk out of the back door of the house, you will be facing east. From there, walk straight ahead 10 feet. Turn 45° to your left, and then walk 5 feet. Next, turn 25° to your right and walk 12 feet. Finally, turn 110° to your right and walk 20 feet.
Based on these directions, which way will Heather be facing when she reaches the place where Dave buried the box?
Answers
Answer: She will be walking south or 90 degrees
Step-by-step explanation:
She walks ten spaces forward from where she started meaning the east
She turns 45 degrees left which places her at northeast
The walking doesn't affect her direction
So look at it like -45+25+110
This equals 90 degrees or south.

A pyramid has a volume of 1,944 inches cubed and a rectangular base with the dimensions 18 inches by 9 inches. What is the height of the pyramid? 4 in. 12 in. 24 in. 36 in.
Answers
Answer: 4 inches
Step-by-step explanation: 1,944 / 18/ 9 / 1/3 = 4
Based on the calculations, the height of this pyramid is equal to: D. 36 inches.
Given the following data:
Volume of pyramid = 1,944 cubic inches.Dimensions of rectangular base = 18 inches by 9 inches.How to calculate the height of this pyramid?Mathematically, the volume of a pyramid is calculated by using this formula:
Volume = 1/3 × b × h
Where:
b is the base area.h is the height.For the base area, we have:
Base area = length × breadth
Base area = 18 × 9
Base area = 162 square inches.
Substituting the given parameters into the formula, we have;
1,944 = 1/3 × 162 × h
1,944 = 54h
h = 1,944/54
Height, h = 36 inches.
