  1. Since nobody was brave enough to attack my 'bum' question, here is one that sounds more 'mathy'... Suppose you have a box with a square base area of 16 square inches. There is a circle drawn inside the base which shares the same center point. The diameter of this circle is 2 inches. Lastly, assume that you have a line segment with length of 1 inch which will randomly appear within the base of the box. What is the probability that this line segment will not intersect the circle?
  2. http://www.scienceofrelationships.com/home/2013/11/11/curves-ahead-the-science-of-female-waist-to-hip-ratio-and-at.html You Can Assume that One Standard Sheet Of Toliet Paper Will Be Enough.
  3. Let's define an ideal arse as having a 0.7 hip to waist ratio. Given this ratio and the shape of one's behind describe the best course one should take when wiping themselves after using the restroom.

  5. Suppose we have a ten inch line segment. Draw two isosceles triangles with legs of 3inches such that each begin at the end of the line and their hypotenuse is opposite of the base line. Extend the hypotenuse lines such that they cross above the middle of the line segment. Draw a line from the height of each triangle to the bottom end of the other triangle (the acute angle). At the top a four-sided shape is formed. What is the area of this shape? Solve it without calculus.
  6. your last comment was actually the inspiration of this question.
  7. I agree. I didn't see logos response of 18 given that it was moved up due to someone liking it.
  8. My assignment shows the 18 solution. Maybe, I misunderstood Logophobics solution. I see now what happened, someone gave a 'plus one' to his result. Moving his response out of sequence. I did not see their 18 result and therefore thought they were suggesting a 19 as the chief score. My apologies.
  9. Suppose there is a hat that contains the numbers 1,2,3,4, and 5. You seek to find the three. You blindly reach into the hat pulling out a number. If it is wrong, then without replacement you reach for another. When you pull out the three you stop. Each pick before three is subtracted from 0 with your final pick (the three) being added to that total. What is your expected value?
  10. Your assumptions are correct but I have an answer smaller than 18. I will recheck my numbers maybe you should to.
  11. Suppose a baseball player runs at a speed of 24 ft/s. He is trying to run on a baseball field where it's 90 feet to each base. Determine the rate of change to second base once the runner reaches halfway to first base.
  12. I still have a different solution
  13. The coins spin at the same rate. The diameter of the coins only matter in this story if we wanted to determine how much sooner one coin would finish before the other one (if there have the same diameter) However, yes, I would think it is safe to assume that x and y are measured in inches. If you recall from a post i made a long time ago, we saw that if two identical coins were spinning around a circle (even if the circle is defined without width) the coin on the inside of the circle would finish the circle sooner relative to the ratio of coin size to the centers of rotation that the coins spin in.
  14. Suppose we have a sine (x) curve over the domain [0,pi]. Two coins will (roll/spin) starting at x=0 and go to pi. The coins have a diameter of 1 inch. If one starts on top of the curve and the other rolls from the bottom side of the curve, which coin would make it to pi first?
  15. Let's say we put up two vertical walls meeting at an 120 degree angle. Then we draw a line on each wall, meeting at the intersection of the walls. Each line makes an angle theta with the horizontal; one goes up from the intersection and the other goes down. What angle theta should there be that the two lines form the angle 137.5?
  16. How many spin-able numbers are there from 0 to 99999 ? This is a no-computer puzzle, only right answers with explanation will be accepted. nevermind
  17. Five people (A,B,C,D,E) each need to complete one task (1,2,3,4,5). The amount of money each person would need to complete each tasks is reported in the matrix below. 1 2 3 4 5 +---------- A | 8 3 5 4 3 B | 2 6 9 4 7 C | 6 1 8 4 3 D | 5 7 9 8 8 E | 5 7 9 4 3 As the assigning manager, who should do which task?
  18. You enter a room with two chests. You know that one chest has a lot of money (but you are unsure as to which). You know the other chest has half as much. Being the greedy person you are you want the most money but the chest are indistinguishable from each other outside of opening and counting the contents. You picked the first chest. Just before you open it, the owner of the chests offers you an opportunity to switch. Should you?
  19. Pretend you have a rectangle that is divided into two smaller rectangles where the area of one rectangle is twice that of the other rectangle. If you were to pick a point at random inside the rectangle, what is the probability that the point is within the larger rectangle?

    Star area

    Not until you have raised the question. Clearly their must be an upper bound and lower bound between which the area could exist.

    Star area

    my mistake. I did mean to state symmetry. well done!
  22. Suppose we have two congruent equilateral triangles with side length of 8ft. They are on top of each other in the same orientation. Now One triangle is rotated by 180 degrees and is laying on top the other triangle forming a star. The triangles are positioned relative to each other such that the distance from the base of one triangle is 6ft to the base of the other triangle. What is the area of the star?
