Answer in proper significant figures.
ive tried to answer this four times and missed it all 4 times
missing something i guess
yes i understand that
i know when i multiply I take the smallest amount of sig fig
and when i add or subtract i take the number of least certainty in common
its when i do both im getting confused
i assume i do the parenthesis first
which comes out to 3389.67
do i round that to two sig figs or subtract first?
so the first answer is 3400
then i take 302.17 - 3400
-3097.83 or 3098 in sig fig
well its supposed to be 320.17
so -3079.83 which would be 3080 in sig fig?
which i tried that answer and it marked me wrong >.<
Submitted Answers ANSWER 1: Deduction: -3% 320.17 - (6101.4/1.8) = -3069.50 ANSWER 2: Deduction: -3% 320.17 - (6101.4/1.8) = -3079.83 ANSWER 3: Deduction: -3% 320.17 - (6101.4/1.8) = -3080 ANSWER 4: Deduction: -3% 320.17 - (6101.4/1.8) = -3070
yes but when you subtract dont you take the last significant decimal place to them both?
could you show me how you would solve this so i may understand?
i swear to you im not trying to get anyone to do my homework, but this is frustrating me and i have two more attempts >.<
yes i understand that
but here i divide first
which gives me two sig figs
33.89.67 = 3400 right?
then i take 320.17 and subtract 3400
since 3400 has no decimal spots i round to the nearest 1 spot
and that how i got 3080
oh so the two sig figs i get when dividing applies still after i subtract?
for some reason i thought when i rounded to 3400 i was done with the division part
but 3400 is ambiguous huh
still 2 figs
would it be 3100 or -3100?
you are my hero, thanks a lot!
most certainly did
now i have to do the other three parts of the question but at least I understand a little more
well i understand mult/div and add/subt.... a little confused when they use both together
my book sucks at explaining! and thanks for the pdf
well its a custom made book for my college made by pearson
Just says Chem 121 College of Southern Nevada
first solve the bracket and then do subtraction and finnaly the rules of significant.
