Hello there!
y = 1/2k
Hope I helped!
Let me know if you need anything else!

Whats the format its suppose to be written in?
UPDATE: Y=
+
we know XYZ is an isosceles, thus XY = YZ, the perpendicular segment bisectors of QR and QS are also equal to each other in length, because they both are segment bisectors and thus YR=RX=YS=SZ, so any perpendicular line stemming from the same length on each side will meet its counterpart right on the middle of the triangle.

Answer:
1.
Anya could find out her volume by multiplying 1.5*1.5*4 and then subracting that from 11*8.5.
Terrence could find out his volume by multiplying 3*3*4 and then subtracting that from 11*8.5
Anya's suggestion would maker a larger volume.
There can be 2 different volumes because someone might cut out more than the other person.
2.
I think there's something missing from this question.
Answer:
the cost of each book = $24
Step-by-step explanation:
(if all the books have the same price)
Let x be the price of one book
“She had $157 and After buying 6 books ,she was left with 13$“ means
“157 = 6x + 13”
now we have an equation to solve :
157 = 6x + 13
⇔ 157 - 13 = 6x
⇔ 144 = 6x
⇔ 24 = x
