In Triangle XYZ, A is the midpoint of XY, B is the midpoint of YZ, and C is the midpoint of XZ.
Also, AY = 7. BZ = 8, and XZ = 18. What is the perimeter of Triangle ABC?
Make sure you explain why and show all your work.
Answers
Answer:
The perimeter of triangle ABC is 33.
Explanation:
AY = 7 is half of the line of XY so we would then multiply 7 by 2:
7 x 2 = 14
and we would then do this to all of our numbers:
8 x 2 = 16
18 x 2 = 36
now we make a full equation for the answer of the perimeter of triangle XYZ:
14 + 16 + 36 = 66
66 is the perimeter of triangle XYZ.
We would then divide this answer by 2 to find the perimeter of ABC because it is half of XYZ:
66 ÷ 2 = 33
The perimeter of triangle ABC is 33
Hope this helps! :)

Tony bought 255 1-inch nails and 5 boxes of 2-inch nails. Each box of 2-inch nails had equal amounts of nails in them. He bought a total of 620 nails. Find the number of nails in each box of 2-inch nails.
Answers
Answer:
73 nails
Step-by-step explanation:
Number of 1 inch = 255
Boxes of 2 - inch = 5
Each box of 2 _inch has equal amount of nails
Total number of nails = 620
Number of nails in each box of 2_inch nails:
Let Number of nails in each box = b
Number of 1_inch + 5 * number of 2_inch = 620
255 + 5b = 620
5b = 620 - 255
5b = 365
5b / 5 = 365 / 5
b = 73
Hence, there are 73 nails in each box of 2_inch nails

Answer:
A) 29/40
Step-by-step explanation:
The formula for this is ...
P(A or B) = P(A) + P(B) - P(A and B)
Filling in the given values, you have ...
P(A or B) = 9/20 +1/2 - 9/40
P(A or B) = 18/40 +20/40 -9/40 = (18+20-9)/40
P(A or B) = 29/40 . . . . matches choice A
