bonus ?

Yeah, my 'paint' skills suck, but pretend these are pennies...
Move only 3 to turn the direction of the arrow to face yourself (if they were on a flat surface in front of you...). Which 3 do you move??

You are on a raft thats in a river and on one side of the river is a fox and a carrot. On the other side is a rabbit. You can only carry one at a time, get all three on the same side of the river along with yourself, so you can prevent the fox from eating the rabbit, and the rabbit from eating the carrot. If this is understandable, then how do you accomplish this feat??

Multiple trips
Trip one - bring the rabit over leaving on the other shore the fox and the carrot
Go back to the other shore leaving the rabbit on the other side
Trip two - now bring the fox and the carrot

Move the top penny to the very bottom in front of you
then move in right most and the left most penny from the row that currently has four pennies to the row that currenty has two pennies (one should be put on both sides of the two existing pennies) this will allow you to have done a full roatation of the penny arrow

The penny one is right.
The raft one, I worded wrong. All 3 are on 1 side of the river to begin with. You are correct in first taking the rabbit, however your raft will not carry both the fox and the carrot simultaniously. The raft will only carry 1 thing at a time (other than yourself of course).

ok so it would be many more trips assuming I dont want rabit stew and eat the rabbit and carrot then only take the fox
trip one - take the rabit go on raft alone back
Trip two - take fox - leave the fox on the oposite shore and bring rabit back with me to the other side
Trip Three - leave rabbit on the starting shore take carrot over to the side with the fox
Go back to the oposite shore alone
Trip four - take the rabbit over to the shore where the fox and the carrot are

ooohh, you're good!!

solve this one...
each one is a house
I I I
E G H
E= electric
G= Gas
H= Heating
You have to connect each house with each of gas, electric and, heating with out crossing over each line or crossing though the houses

this one is hard

 

[mukiwa]

So can you go from one house to the next? Like take Heating and move it to one house and then move it to the left to the next house?

in a two dimesional flat drawing this is not possible to do without at least 2 lines crossing inside the loop that would be needed to connect all other nodes - the only way this can be solved is by using a special kind of two-dimensional surface. This special place is the outside of a torus. A torus is shaped like a perfect doughnut, with a hole in the middle.
This allows the lines to go into the hole and then wrap accordingly so they dont cross
