64 copies.
1.) Divide 40 by 5 (you get 8)
2.) 8 is the number of copies that fits on a 1 foot shelf, so to find how many copies would fit on an 8 foot shelf, simply multiply 8(book copies) by 8( an 8 foot shelf).
3.) 8 times 8 is 64, so your answer is 64 books will fit perfectly on an 8 foot shelf. Hope this helped!
Answer:

Answer:
D) a = b= 2√2
Step-by-step explanation:
The hypotenuse of an isosceles right triangle is √2 times the side length. This means you have ...
a√2 = 4
a = 4/√2 = 4(√2)/2 = 2√2
Of course, the side lengths are the same (as all answer choices show you). The correct choice is ...
a = 2√2, b = 2√2
Answer:
I think the answer would be 33. I am not exactly sure though.
