Good night Milica.

prove that 0.999999...999 = 1

Night little maths wizard :)

I wanted to go to bed but now I have to write this. :P

 

a=0.99...9

10*a=9.99...9

9*a=10*a-a

9*a=9

a=1

^very good!

The second choice....

 

It sounds like more....

Imagine for a second you have received an email, which isn't spam nor trying to steal your bank details, but it says:

Congratulations you have won a prize in the prize raffle, the 2 prizes you get to choice from are either:

1 - A one-off payment of 1,000,000,000 units of money

or

2 - 31 daily payments, starting with 1 unit, which keeps doubling, so day 2 you will get given 2 units (plus the 1 you got given on the first day) and day 3 will be 4 units.

 

Which of the 2 options would you pick and why?

 

(2^31)-1 = 2,147,483,647

 

if I did that right, which is the total for doubling every 31 days. so I would choose that one

Eric, we should get married. :cheesy: I calculated that the exact same way. :wacky:

another question?

 

If a certain number, N, is divided by d, the remainder is 7. If the original number, N, is multiplied by 5 then divided by d, the remainder is 10. Find d.

found it

Bryce, is it 25?

 

Don't shoot me if I'm wrong. :P

I haven't done math in a while...... but I think that's impossible.... :P maybe there is some kind of math that I'm missing

 

N/D = 7 ; 7D = N

 

5N/D = 10 ; N/D = 2 ; N = 2D

 

If that's the case, then 2D = 7D ...

 

Even if D = 0, it doesn't work for the first two equations.

 

It also seems likely that I just didn't read your question right....

:uhoh: my goodness.....

this is why we don't have friends :disappointed:

 

one day, when the world needs math again, people will beg to be my friend :blush:

I hate math...and science...those two can burn!!!!!!!!!!!!!!!!!!!! :evil:

Okay.

 

Turn off your computer, turn off the lights, you're not allowed to use TV anymore, nor the fridge. You can't see your doctor anymore. You don't have any recorded music anymore.

I hate math...and science...those two can burn!!!!!!!!!!!!!!!!!!!! :evil:

 

if math and science burn, there is no more universe :P

I DON'T CARE!!!!!!!!!!!!! I will live off of history and my kick ass grammar skills :smug:

History without dates, population statistics and all other numbers?

I DON'T CARE!!!!!!!!!!!!! I will live off of history and my kick ass grammar skills :smug:

 

history will be all there is, because there will be no more solar system :P Gravity would collapse, heat and friction would be nonexistant, and there would be no more matter :P

Eric. Seriously. :wacky:

I DON'T CARE.

Now shut up before I de-friend you :whip:

:charming: chicks dig a nerd

I HATE Doctors.
