Answer:
9
Step-by-step explanation:
Pythagorean Theorem
a²+b²=c²
(c² is the hypotenuse)
a² + 40² = 41²
a² + 1,600 = 1,681
subtract 1681-1600 in order to isolate a², which is the missing leg we are trying to find
a² = 81 in order to find our answer, we isolate a by squaring both sides
√a² = √81
a = 9
Our answer is 9.

Answer:
68
Step-by-step explanation:
Alright, so to find how many pages that can be had, we have to replace P with the amount of money Jennifer has. This is because P is the price of one book, and we want to find the number of pages (x) we can buy for a book price of 62.10 or less.
62.1 = (20 + 0.5x) + 0.15(20 + 0.5x)
62.1 = 20 + 3 + 0.5x + 0.075x
62.1 - 23 = 0.575x
39.1 = 0.575x
39.1/0.575 = x
x = 68
Therefore, in order to buy a book that costs 62.10, the book must have 68 pages.
