Your question: Sea water has 3% salinity. How much volume of water (in litres) should be expelled to get 2% salinity?
Is this ur question?
Was my ans right?

Answer 29

yea this was the q..but i don't know how to solve it.....idk if ur answer is right...:(

ok, my logic goes:
In 100 L water there is 3 vol salt.
Therefore 1 vol salt is in 100/3 L water
So 2 vol salt is in 200/3 L water.

\[\lim_{x \rightarrow 0} {|2x-1|-|2x+1|}/x\]

Answer 56

hahahaha loool :D :D

Answer 57

**********all that is divided with x**********

Answer 58

answer=-4

Answer 59

O.o some explanation plssssssssssssss ^_^

Answer 60

well, for x=0+c and x=0-c we have |2x-1|=-2x+1 and |2x+1|=2x+1.
here c is the smallest number u can think of.

Answer 61

so that gives the fraction lim(x->0)(-2x+1-2x-1)/x=-4.

Answer 62

any problems ask me:)
