after subtracting, i ended up getting 25190, but since you had to round to the hundreds, my answer came out to be 2520

  • anonymous
unfortunately, my answer is incorrect. can anyone tell me what did i do wrong?

In "4659¯0", what does the " \(^-\) " mean?

it's just a bar, meaning it's in the tenths place
aaronq
  • aaronq
so it's like a decimal point?
anonymous
  • anonymous
the bar is on top of the number 9

i guess

4659.0−214.00, is this equivalent to what you have?

it has the bar instead of the decimal point

4659.0−214.00=4445 you had 5 sig figs initially, so 4445.0
anonymous
  • anonymous
hmm let me try
anonymous
  • anonymous
there's a hint option. it gives you a question that asks" 4659¯0 has the final significant digit in the tens place and 214¯00 has the final significant digit in the hundreds place. To what place will the final answer be rounded?"
anonymous
  • anonymous
the answer came out to be hundreds
anonymous
  • anonymous
so the answer should be 4450?
aaronq
  • aaronq
if you're keeping the amount of sig figs, it should be 5 sig figs.
aaronq
  • aaronq
the answer doesn't need to be rounded because they're all integers
anonymous
  • anonymous
i got it wrong
anonymous
  • anonymous
but thanks anyway
aaronq
  • aaronq
4450.0 is not the answer?
anonymous
  • anonymous
nope
aaronq
  • aaronq
what is the answer?
anonymous
  • anonymous
i got two more attempts
aaronq
  • aaronq
i see. that's odd, though.
anonymous
  • anonymous
yeah..
aaronq
  • aaronq
maybe it's the bar, i don't know if were interpreting it right.
anonymous
  • anonymous
thanks anyway
aaronq
  • aaronq
sorry, dude. Maybe ask in the math section?
anonymous
  • anonymous
alright, i"ll try.

The bar on top means the numbers on the left of it are significant including the one with the bar . You take the one with the least amount of significant numbers. 214¯00 -> You round the answer at the hundreds. so 46 590 - 21 400 = 25 200 if its for mastering chemistry, i tried it and it worked :)
