  1. My try at it

    Spoiler

    Consider the middle pin to be any color (since it doesn't matter) so lets say "o". Now consider all the pins adjacent to it and note that the adjacent faces of the hexagon have to have either both be the opposite color of the center or one has to be the same and the other has to be different from the center. There is only one way (really a bunch with mirroring and rotating) that this can be accomplished without creating the same color triangles

          x     x

    o        o        o

         x        x

    No consider the bottom two corners of the larger triangle. They would have to be "o" in the schematic because of the bold underlined "x"s. With both of those the top would have be an "x" because of the largest triangle possible would be the same color but this can not be because the triangle created by the top 3 pins.

    Therefore this is not possible and this guy is clearly hammered since he couldn't see this.

     

  2. Think I have the ideal solution here

    Spoiler

    A (0,0); B (1,0); C(1,1); D (0,1); E (cos(30),sin(30)); F (cos(60),sin(60))

    This solution assumes if you are excatly the same distance from points you get to choose. Very slight tweaks to the points can force the longest path

    Start at A. B,D,E&F are all 1 mile away so pick E (+1 mile)

    At E. B and F are both same distance away (2 sin(15)~.5176) so pick B  (+.5176 mile)

    At B. A,E,&F are all 1 mile away so pick F (+1 mile)

    At F, D is closest (2 sin(15)) (+.5176 mile)

    At D, C is closest (+1 mile)

    At C, return to A (2^.5~1.414

    Total distance walked= 3*(1)+2*(2sin(15))+2^.5~5.449

     

     

  3. The first number is the lowest possible answer, the dots represent a series of numbers that fit the sequence. Give the 3 blanks in the sequence. You might have to think alittle off the wall *wink* to come up with the pattern.

    2, 3, 5, 20, 26.......... 929, 930, 936, 939, 948, 950, 956, ______, _______, ______....2038, 2058.....

    The number is 840

    Start with number 2. Must be True. That makes number 1 False. Which makes 7 and 8 False. With 7 False we know the number is <=1000. With 8 False we know there are exactly 5 True and 5 False statements

    So Far we have 1)F 2)T 3) 4) 5) 6) 7)F 8)F 9) 10)

    Now assume number 3 is true. If the number is prime, then 4, 5, 6, and 9 must be false. That would mean that there are 7 false statements which contradicts the conclusion about number 8. Therefore 3 must be False.

    Now we have 1)F 2)T 3)F 4) 5) 6) 7)F 8)F 9) 10)

    Next we look at statement 10. Assume it is True. This makes 9 False and 4,5,6 True. The number would be defined as <1000 (statement 7), has 18 as divisor (statement 4), has >27 divisors(statement 5 {2+4+5+6+10}), has 4 prime divisors (statement 6), and divisor is not a cube (statement 9). The only number divisible by 18 that has more than 27 factors is 720. This is divisible by 8 and therefore can not be true. So statement 10 must be False.

    This results in the statements as follows 1)F 2)T 3)F 4)T 5)T 6)T 7)F 8)F 9)T 10)F

    So the number must be <1000, divisible by 20, divisible by a cube, have 4 prime divisors, and have >26 divisors. The only number that fits this is 840.

     

  5. my bad. I left a couple options for the exterior primes off my list.

    It is possible, I have it. I will show it next week if nobody find it until 10 Nov 2016.

     

    Spoiler

    3 1 1

    1 5 7

    1 7 9

     

    Fun extra question to add in to challenge on this one. What is the lowest number of unique primes that could be used in this and how many unique ways (including rotation and reflection) can this be made?

  6. Spoiler

    Take number 27 (the middle road)

    The first 4 villagers can not be "useless" based on the possible outcomes of their clues. This leaves the remaining villagers. Only 1 combination of numbers leaves 3 of them giving useless information (15, 27, and 39 would have villagers 7, 8, and 9 giving useless information. From there its just a matter of testing the remaining outcomes.

     

      15 27 39
    W R W
    2 R W W
    3 W R W
    4 W W R
    5 R W R

    8 U U U
    9 U U U
    10 W R W

  7. Spoiler

    Firstly, there's way to many rectangles so I'm going to logic some away. Any time a rectangle shares the same full line segment that segment can either be an integer or not. By that logic, the other side of the rectangle would be the opposite. This means the combination of these 2 rectangles has the same properties as the 2 smaller rectangles. You can use this logic multiple times and end up with only 5 rectangles that look roughly like this

         
         
         

    Now the figure is effectively rotationally congruent so we only need to prove one side full side in an integer and the proof will hold for the other possibilities. So both line segments that make up the right side can be integers, on is and one isn't, and both aren't.

    Both integers obviously proves the theory for that case

    One integer and one not creates a situation where the center rectangle will either have to both sides be integers or both side not be integers which contradicts the problem requirements.

    Both non-integers creates a situation where both of the top have to be integers and proves the theory.

     

  8. I can move the good Dr. for less than $25

    Spoiler

    In 324 total steps the Dr. can visit every vertex for no more than $12.60 going either way.

    Method: From the starting point move in one direction (say Clockwise), then move across, then move in the other direction (CCW) until moving across would bring you to a new location. Then move across and begin moving in the original direction until you reach a new vertex. Repeat until completed.

    Data. Assume starting at #1 and all vertices are number around clockwise from here.

  9. Spoiler

    2X4X20

    Areas 8:40:80

    since 160 broken down into its base is 5x25. this meant that since the ratios of B and C both contained a factor of 5, the shared side had to be a multiple of 5*2x. the rest had to be 2x where the sum of the 3 unknown powers had to sum to 5. This takes you to a very limited number of possibilities which are easy enough to just calculate.

     

  10. Spoiler

    Make a cut that is along the line created by the center of the cake (if it were whole) and the center of the rectangular piece missing from the cake.

    Since and straight line cut through the center of a rectangle is equal areas when you make a cut that goes through the center of both, you are taking equal area of both the cake and the missing piece so the remaining has to be equal.

     

    • Upvote 1
  11. Assuming a tie vote of the remaining means its ratified

    Spoiler

    The oldest suggest 9,1,0,2,0

    Simply if the it gets down to the last 2 the youngest will get all the gold so the youngest will always vote no. The second youngest knowing this will want to make sure that it doesn't get there so will vote yes for anything 1 or more with only 3 people left. So the third youngest would ideally suggest 11,1,0 split to get the split vote and 11 for himself. This leaves the second oldest with no possible options since the middle is expecting 11 gold and the youngest is expecting 12 so nothing her can do will please a majority of bankers and give him any gold. The oldest knowing all of this just has to make sure that the second and fourth youngest are getting more then they would if the first vote wasn't ratified. knowing that going further the 4th is destined for none and the second is destined for 1, he offers 1 and 2, respectively and can keep the rest for himself.
