Question

Having trouble with a significant figures calculation. The answer must have the correct number of significant figures, and im not sure if the answer is 16.09 or 16.093. Help would be appreciated so much!!
(17.103-2.03)+1.02021

Answer 1

16.09 because you can only have the smallest amount you already have of sig figs do you udnerstand?

Answer 2

yeah, i thought it was that one, but i wanted to make sure. its on my study guide and with my test tomorrow i wanted to make sure i understnadit. thanks so much! :)

Answer 3

here let me copy and paste the rules i have from my online class

Answer 4

The final answer cannot have more places after the decimal than any of the given measurements.
The final answer cannot have a final digit, which represents the uncertain or estimated place, farther to the right than any of the final digits in the measurements used.
for addition and subtraction

Answer 5

Only given measurements affect the number of sig figs allowed in the final answer. Equivalences used to convert units do not affect the sig figs allowed in the final answer because they are memorized relationships that were not measured with a specific instrument.
If you are only given one measurement, the total number of sig figs in that measurement equal the total number of sig figs allowed in your final answer.
If you are given more than one measurement to be used in a calculation, the final answer must be rounded to the same total number of sig figs as the measurement that has the least total sig figs.
for division and multiplication

Answer 6

I think i understnad that better than the way the book explains it. thanks! :)
