A geometry puzzle?
-
--------- #1454 - There was this old stone wall separating two farms. Each farmer had 600 feet of fence. One farmer wanted to have maximum rectangular area using his fence and the wall for one side. What was the length of each side of the fence he designed? The other farmer wanted to have only two sides of the fence and for them to be the same length and still have the maximum area in the triangle. What was the length of each side of his fence and what angle did the fence meet the wall?.

Long term the car is cheaper? PUZZLE
--------- #1462 - PUZZLE: The car repair problems
-
- Puzzle for week 17, there is a sequence of numbers with one number missing:
-
--------------------- 1, x, 2, 4, 7, 11, 16, 22, …………………
-
- What is “ x” the number that is missing?
-
-- Answer = ?
- If you need help find the answer to this equation, find x: (square root x) ^ x-1 = x
-
- - Answer one, x = ? - -------------- - Answer two , x = ?
-
- The first answer helps you with the first problem and the second answer helps you with the following problem:
-
- Doug, Dave and Matt took their cars in for service on Monday, Tuesday, Wednesday. One of their cars was red. The black car was not the one to get the oil change. On Monday one of the cars got new tires. Dave’s car was worked on before the car whose lights were repaired, but after the silver car. Matt’s car was not black.
-
- What was the color of each guy’s car, and who got what done when?
-
- Answer = ?
-
- Let me know when you are ready for me to send you the answers:
