I actually like it more than this website, this one is so slow and well boring. The other one is always busy with questions and u can meet so many ppl there! I luv it. U guys SHOULD try it!
Do you want to calculate sqrt by hand? There is no easy and fast way to do it by hand, compared to a calculator.
what is 30.0079 rounded to the nearest whole number
=30 rounded to the nearest whole number.
You haven't provided enough information!!
You need to provide the data. We can't see it!
efficiency = Energy out/Energy in
efficiency = 300/1000 = 0.3 or 30%
However, your energies don't balance 300 + 9650 + 70 > 1000
WOW. You are a star !!
I do not think that it is downloadable - It is just online. :)
6ml = 0.006l
There are 1000 millilitres in a litre.

Neither; in general it's just a number.
tanh(x) = (ex - e-x)/(ex + e-x) x doesn't have to be an angle.
x = 3 (y = 0) is certainly a solution, but x = -1 isn't!
Always pays to put your solutions back into the original equations to check.
(The other solution is x = 1/2, y = 5)
