70

In any case, 70.

Not that tricky. Just have to remember that you said divide, not multiply. If you multiply 30 by 1/2 and add 10, it's 25. But if you follow your instructions, it's 70.

70<br />

30/0.5 = 60+10 = 70

absolutely

70

Dude here's how I got it half of 30 is 15 unless you are doing something entirely different with the fraction and then you add 10 to 15 and get 25.

sorry dude....wrong

then I want to know how you get the answer coz I suck at math.

and no this does not warrant the answer obviously.

30/0.5 = 60+10 = 70

why do you convert it though? Why don't you just go 30*1 divided by 2+10?

half of 1=0.5...
also i didn't say 30 divide in half....i said 30 divide by half

ooh gotcha thanks :)

The answer is way over my head. I don't have a clue honestly. lol

fair enough

I'm slow at math. I've just learned to joke about it.

yep ..slow but sure. i suppose..lol

Damn solar powered calculator :(....never works in down here in the cellar

How is this tricky? I divide with percentages all day.<br />
Summarize for me, the index is (i=1) (the part below âˆ‘) and the upper boud (the part above âˆ‘) is infinite: (1/i^2). In other words: you start with (1/1^2) then add (1/2^2) then add (1/3^2) etc. and those sums go on infinitely. What's the answer?

professor...i need an answer.if u havn't got it.then u r pretty
useless to every one here

lim (i=1 to infinity âˆ‘(1/i^2)) = 2

Ok your answer is 25. Devide 30 by 1 = 30; 30/2 = 15; add 10 and you get 25.

Madres, are you using a calculator?
