sea water contains 3% salinity.how much water should we throw out in 1liter....so that the percentage will b 2%

is the answer 200/3 L.?
angela210793

idk.......
anonymous
  • anonymous
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?
angela210793
  • angela210793
yea this was the q..but i don't know how to solve it.....idk if ur answer is right...:(
anonymous
  • anonymous
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.

answer=-4
angela210793
  • angela210793
O.o some explanation plssssssssssssss ^_^
anonymous
  • anonymous
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.
anonymous
  • anonymous
so that gives the fraction lim(x->0)(-2x+1-2x-1)/x=-4.

anonymous
  • anonymous
use the fact that x1+x2=2-b and x1x2=b. observe that 1/x1+1/x2=(x1+x2)/x1x2=(2-b)/b.now this equals 3. b=1/2.

is it ur high school final exams? Best of luck.. (never do what u dont like, its no use getting high marks in a subject u dont like....i like ur spirit..God has given us abilities in a particular field and we should exploit it to the fullest to become a genius like beethoven or einstein . This is what i believe:)
angela210793
  • angela210793
Huh? Noooo......... it's true that i don't like it but i study it anyway..i must have a good grade's average to go to unviersity...... and my grade's average would b abt 9.7 if there was no math :S
anonymous
  • anonymous
whats the meaning of "earning a grade" if u dont like what you do. We are not compelled to do anything. We do it because we love to do it and spend the time of our life in doing what we like. The main thing: We should have fun throughout our lives.
angela210793
  • angela210793
the meaning is to go to a good university.....:)
