0.01/100 = 0.0001 x 1000 = 0.1lb

huhhh??

if 100 samples ---> 0.01 lbs then 1000 samples ---> x? cross multiply and solve for x ^_^

ok..hmm
anonymous
  • anonymous
100x = 1000(0.01) x = 1000(0.01)/100 ^_^
anonymous
  • anonymous
did you get the way?
anonymous
  • anonymous
do i multiply 0.01 & 10?
anonymous
  • anonymous
100x=0.01. Therefore, x=0.01/100=0.0001 so x * 1000 = 0.1lb
anonymous
  • anonymous
0.01 x 1000 then divide by 100 ^_^
anonymous
  • anonymous
0.1?
anonymous
  • anonymous
excellent!

The weight of identical samples of a substance is 1 pound. What is the weight of samples?
anonymous
  • anonymous
I'm sure of my answer
anonymous
  • anonymous
wait... The weight of 1000 identical samples of a substance is 1 pound. What is the weight of 10 samples?
anonymous
  • anonymous
answer 0.1 pounds???
anonymous
  • anonymous
I'm sure
anonymous
  • anonymous
its 0.01 ..
anonymous
  • anonymous
how come?
anonymous
  • anonymous
1000 x 0.01 = 10 10/100 = 0.1
anonymous
  • anonymous
this is what it says...now this is what i'm dealing with. it explains it sooo confusing...u ready?lol
anonymous
  • anonymous
it says the weight of 1000 samples is one pound. to find the weight of 1 sample we divide 1 by 1000. ---> weight of 1 sample = 1 divided by 1000= 0.0001 The weight of 10 samples is 10 times this amount. weight of 10 samples = 10xweight of one sample ___> 10x0.0001=0.01 pound.

  • anonymous
but you wrote that it's 0.01 lb
anonymous
  • anonymous
intially in the question lol
anonymous
  • anonymous
the question was The weight of 1000 identical samples of a substance is 1 pound. What is the weight of 10 samples?
anonymous
  • anonymous
LOL! see what you wrote in the question >_< you said 0.01 !
anonymous
  • anonymous
ohhhhh my bad! wow.

the volume of 1000 drops of a liquid is 10 fl. oz. What is the volume of 10 drops?
anonymous
  • anonymous
and im sure thats the question this time LOL
anonymous
  • anonymous
do it the same way I solved the previous question: if 1000 drops --->10fl 10 drops -----> x? cross multiply and solve for x ^_^ try
anonymous
  • anonymous
like 1000/10 X 10/x ?
anonymous
  • anonymous
lol no, cross multiply and you'll get: 1000x = 10(10) x = 100/1000 x = 0.1 ^_^
anonymous
  • anonymous
draw an X between them and you'll get 10(10) = (1000)x
anonymous
  • anonymous
^_^ did you get it?
anonymous
  • anonymous
yeah but im not sure why u divide 100/1000
anonymous
  • anonymous
to solve for x, you have : 1000x = 100 right? now get x alone and we do that by dividing both sides by 1000 x = 100/1000 :)
anonymous
  • anonymous
is it clearer now? :)
anonymous
  • anonymous
got it!!!
anonymous
  • anonymous
great :)
