[NuclearSilo]

This thread will be the reincarnation of Minimax's riddle thread. I got it from a book so i share with u.

Enigma #1
Type: Easy

[RuYi]

Like this? :3

[Squirt]

This is a math riddle thread ?

Lol This was confusing =/

[[SD]Kratos]

i failed to find the answer but i like ruyi's paint skills.

Heh. What can I say?
Not everyone is blessed with the artistic skills of a badger.

[NuclearSilo]

Well, stupid question anyway.
__dRe win! RuYi too..

Enigma #2
Type: Extreme

Q: U have a saw, u have to saw a piece of glass (size 24x24)into 4 same pieces (shape, surface) and then to let them go through a ring diameter 5cm.

(answer with pic, only straight line allowed, not curved)

Hint: each piece is 144 cm² and 24 is divible by 3

[Stress]

I can only get them through 10,6 diameter ring. Sill working on it

[exality]

Close as i can get is 8.4 cm

[Skayunor]

Blegh, 5.65 cm, I shouldn't even try this knowing math gives me headaches.

[whiteraven]

i took the piece of glass,, melted it, made 4 balls of it, (diameter smaller as 5cm)

put them trought the ring, and run over the finish line

[NuclearSilo]

i took the piece of glass,, melted it, made 4 balls of it, (diameter smaller as 5cm)

put them trought the ring, and run over the finish line

do it, take much more money and effort than using with only a saw
Next question in 1 week if no one can answer.

well that seems impossible if u dont mind im gonna post a fun one

Spoiler!

using exactly three 3, and any operations +,-,/,*,^....
make all the numbers 1-20

no square cuz square is ^2 and u can only use 3, no celing, floor or approximates
square root is allowed, but dont argue, i got this without using squres


i will demonstrate 3 since its the easiest

1=
2=
3= 3*3/3

*hint use !
i'll give u guys another hint if no one gets it

[NuclearSilo]

Spoiler!

1= 3!/(3+3)
2= (3+3)/3
3= 3*3/3
4= 3+3/3
5= 3!-3/3
6= 3!*3/3
7= 3!+3/3
8= 3!+(3!/3)
9= 3!+3!-3
10= 3
11=
12= 3!*3!/3
13=

15= 3!+3!+3

[whiteraven]

busy to get the answer from my calculator ^^ ,, its called google xD

im going to break the damn question with the right keywords ^^ search for the keywords begins xD

what is glace?

[Da_Realest]

Like this?

[crazyskwrls]

no it is possible

10 does not equal to 3...

heres how u can do ten

10 = .33(repeating sign) *3

now use that to figure the rest out

[FireVortex]

How do u get the square root sign on teh keyboard?

[crazyskwrls]

How do u get the square root sign on teh keyboard?

just type square root (wat ever # u want) or

3^.5

[FireVortex]

ALGEBRA TIMEZ
is an easy ones
2x+2y+2mx-4my+1=0
make "m" the subject of the formula

enjoy

[crazyskwrls]

M = -(x+y+.5)/ (x-2y)
Easy shit

[FireVortex]

M = -(x+y+.5)/ (x-2y)
Easy shit

Hmm show the process .To lazy 2 work it out now.
