By:
Good, you were making me confused there fft ;)
We all agreeing on 3200 then? |
|
By:
3200 is at least one correct answer, however this was derived on the "assumption" that te 5 and the 3 were in a straight diagonal line from corner to corner, and the 4 effectvely goes from one of the other corners to the direct centre of the square. then with pythagoras using 8 as the diagonal of the square, 3200 is easily reached. BUT the assumption is only correct by coincidence. I would like to see a proper proof.
FFT still not making any sense to me. |
|
By:
Yes I am agreeing on 3200m, no probs :)
|
|
By:
I know where you're coming from now pos4th, my mistake :|
|
|
By:
Still haven't seen a satisfactory proof though ;)
|
|
By:
if the 3 & 5 go along the diagonal the 4 would not reach to bull or have some slack in it and therefore not be tight to the bull. The answer cannot be 3200.
|
|
By:
pos, even if the 50m and 40m were joined, and the 30m is at the corner, it still makes 3200.
|
|
By:
Oh. How did you work that out jimbo?
|
|
By:
yes you are right. the only way the 40m rope could exactly hit that diagonal line would be if it went to the middle of the square ie half way along the total (5+3) rope.
You're right, still work to do here I think. |

Q 3. Give half of them nothing, give the rest a bit more than they would each indivually receive if you jumped the plank and they divided it equally among themselves (dont know how many pirates there are so cant be exact and too lazy to work out a formula), keep the rest for yourself.
|

By:
3. You are Captain Jack Sparrow and about to distribute your plunder to your scurvy crew. If more than half of them object to your distribution they will vote to make you walk the plank and keep all the treasure themselves. How can you maximise your own health, safety and take ?
say there are 1000 gold pieces. and 100 crew (includin yourself) Give 50 of them 11 gold pieces = 550, Give 49 of them nothing, and keep 450 for yourself? Only 49 would vote you out!!! I think that is what jbha is saying. good work, hadn't reallly got a clue what that question was about tbh. |

By:
Expenses: does the Tory take the same as the Labour MP: 12 days?
Capt Sparrow: divvy it up between himself and half the crew, leaving the other half of the crew with 0? |

By:
Thanks for all the effort guys. I think I will go with 3200 at the moment until I see a more convincing argument.
What do you think about the other questions? I think the pirate one maybe give half the loot to half the crew so they all get an equal share, and keep half the loot yourself. Here are the other questions from that section (I think I already have the answers to the but wont post the yet so if you want you can have a go) What is more likely to fall on a Friday than any other day ? A normal duck has two legs. A lame duck has one leg. A sitting duck has no legs. Ninety nine ducks have a total of 100 legs. There are half as many sitting ducks as normal ducks and lame ducks put together. How many lame ducks are there ? Where might you get rejected rather then selected ? What are the 10 types of mathematician ? 1 1 1 + 1 1 + 1 = 4 Imagine the incorrect equation above is |
|
By:
Right.
Draw a square, put a line from one corner to the other. This represents the ropes 50m and 30m Angle created is 45 deg Need to prove that from one corner to the middle is 40m, so the rope is tight. Split one of the triangles in two... So we have two angles of 45, a side of length 40m, and two unknown and a right angle. Therefore the line joining to the corner must be 40m. 40m squared + 40m squared = 3200 3200 rooted = 56ish. |

Jimbo747 02 Dec 11:45 pos, even if the 50m and 40m were joined, and the 30m is at the corner, it still makes 3200. sorry mate, but I am not convinced. I am pretty sure the answer to the tory/labour one is 24 days. Best way of thinking of it is this: imagine they have 120quid to spend. labour do that in 12 days, so they are spending 10 qui a day. but with the tories they did it in 8 days during which time labour would've spent 80 quid meaning the tories spent 40 quid in 8 days = 5/day. so it would take him 24 days to spend 120 quid. Maths is easy using 120quid, but could use any figure if you wanted. |

These are some of the other questions I am struggling with:
Financial Section: What went up 8.3% in April ? What was called the rate at which banks dont lend to each other ? What is both a safeguard and an ornament ? May we help you, your company or your parents with financial affairs in any way ? Qui etait le père ? What is unusual about car numberplates in TV adverts ? How many times did Jonny Quid die this week ? What 3 items are banned from grounds for football matches but permitted at rugby matches ? |

By:
my basic theory on the expenses was, together do it in 8 days, individually therefore should do it in 16 days (or at least the average should be 16 days), one does it in 12 therefore other should do it in 20...rob's looks better though
|
|
By:
3200 cannot be right. The 40 rope is not joined to the bull!!!
|
|
By:
ornament and safeguard is a pound coin
|
|
By:
evski is correct. If you assume the 30 and 50 are along the diagonal, then the 40 rope will go to the centre of the square, when the bull is 10m away from the centre of the square.

What is more likely to fall on a Friday than any other day ? Work attendance

i think monday would be the answer to that jbha, you might be along the right track though.

1. What is special about 1/7th ?
You find the pattern of 142857 recurs when you divide any number by 7, if it isn't perfectly divisible by 7? Handy to know when working in a betting shop. £100000 on a 4/7 wins you £57,142.86. Not that see you that bet too often. ;) |

Not that see you that bet too often I picked up on that one too dk. For instance if someone wants to know what 200 divided by 14 is you know it is 14.2857142857etc etc. 400/14 = 28.57142857etc. A couple of times I have had to work something out which involves dividing by 7, and I can reel it off to say 10 decimal places and then they put it in a calculator and see that you were right and they think you are some sort of genius, but it is just a trick. |

That's it pos. You know you're getting 14 lots of 7 into 100, and then you carry on going in the right order. You look like a genius to others, when really you just know that. Have to then keep quiet in front of them to keep the veneer up. :D |
