2) A rectangular sheet of paper ABCD is three inches in width and four inches in length. The paper is folded so that the two diagonally opposite corners A and C coincide. Determine the length of the crease in the paper.

3) If x,y, and z are unequal real numbers whose sum is zero and whose product is two, determine the value of x^3+y^3+z^3.

4)Among grandfather's papers an old bill was found:"72 Turkeys $)_67.9_." The first and last digits of the number that represented the totaly price of the turkeys are replaced here with blanks as they had faded and are now illegible. What are the msising digits?

I am really confused by this, how could I convert it? Could you show me step by step please? And explain as well. I'm stuck, I figured it's about 97.7 seconds per kilometer, which is 137.7 seconds per kilometer, or 1:37.7/1

I figure then I multiply the time by 60 to get how fast it is, which I get like 90 km/hr, which is obviously completely wrong. But I checked the answers in the back of the book but it says 36.88 km/hr. HELP PLEASE!

I recently saw a program on the Discovery Channel about elephants that included a segment where the group they were following came across the body of another dead elephant. The reaction of the elephants was strange, with them stopping to touch the bones of the dead animal with their trunks while they all gathered around. The program suggested that this shows that elephants can grieve for their dead and are thus fully concious beings. Does anyone know of any scientific research about this? Also, what is your opinion?

if the oldest female is always the Matriarch of the herd, what happens if she's not exactly the brightest member of the herd? i mean, if she somehow managed to survive to adult hood and assume that position, what does the herd do if she can't find good places to eat, drink,etc? has there ever been a documented case where this happened?
