[Question]Uncle Ben has 440 chickens on his farm. 39 are roosters and the rest are hens. 15 of his hens do not lay eggs, and the rest do. If each egg-laying hen lays 3 eggs, how many eggs will Uncle Ben have?

Question: Elliott drew a right-angle triangle on his book. It had a base of 4 inches, a height of 3 inches and a certain length of the hypotenuse. What was the length of the perimeter of the triangle that he drew?
Answer: Since the hypotenuse of a triangle is found by the square root of the base squared plus the height squared. The square of the base of the first triangle is 4 * 4 = 16 square inches. The square of the height of the first triangle is 3 * 3 = 9 square inches. The sum of the squares of the base and the height of the first triangle is 16 + 9 = 25. The square root of the sum of the base and the height of the first triangle, which is the hypotenuse of the triangle, is √25 = 5 inches. Since the perimeter of a triangle is found by adding the sides of the triangle, the base and height of the triangle sum up to 3 + 4 = 7 inches. If you add the hypotenuse of the triangle the perimeter of the triangle becomes 7 + 5 = 12 inches. The answer is 12.
[Question]At the family reunion, everyone ate too much food and gained weight. Orlando gained 5 pounds. Jose gained two pounds more than twice what Orlando gained. Fernando gained 3 pounds less than half of what Jose gained. How much weight, in pounds, did the three family members gain at their reunion?
[Answer]Twice what Orlando gained is 2 * 5 = 10 pounds. Jose gained two pounds more than twice what Orlando gained for a total of 2 + 10 = 12 pounds.. Half of what Jose gained is 12 / 2 = 6 pounds. Fernando gained 3 pounds less than half of what Jose gained, for a total of 6 - 3 = 3 pounds. In total, the three family members gained 5 + 12 + 3 = 20 pounds at the reunion. The answer is 20.
Q: Adam has just bought some new books so he has decided to clean up his bookcase. After he adds his new books to his bookshelf he realizes that he has bought enough books to finish completely filling his bookcase with 2 books left over. Before his shopping trip, Adam had 56 books in his bookcase. If his bookcase has 4 shelves and averages 20 books per shelf, how many books did Adam buy on his shopping trip?
A: Adam’s bookshelf has 4 shelves that fit 20 books each, which is 4 * 20 = 80 books in total to fill the bookshelf. Adam ended the day with a full bookcase of 80 books in the bookcase and 2 books left over, 80 + 2 = 82 books total. If Adam started the day with 56 books and ended the day with 82 books then Adam bought 82 - 56 = 26 books bought on his shopping trip. The answer is 26.
