Question

ik his one is hard, but i will medal an fan!

Total these measurements. Your answer should indicate the proper accuracy. Be sure to include the m in your answer. (Remember when adding figures, you need to round your answer so that it reflects the figure in the problem with the least amount of significant figures to the right of the decimal if a decimal is present).

8.3 m
5.2 m
4.36 m
42.1 m
86.0 m

Answer 1

are you basically asking to add all of these values together? o.o

Answer 2

because if that is so, all you have to do is align the numbers, making sure the decimal points are all together. Then add them together like you would normally add

Answer 3

im not sure, im confused oon this question

Answer 4

well..if it says to total the measurements, I'm assuming that the question is asking you to combine the subtotals for an overall answer. Which is just a fancy way of saying add everything together, I do believe. It almost seems to easy though.

Answer 5

i rounded them and added them and got 145m. does that seem correct?

Answer 6

it does seem correct, if you rounded all the decimals to the nearest 10th

Answer 7

okay thank you :)

Answer 8

no problem, I hope that's right! I haven't seen a problem like that in a while

Answer 9

don't round early, round at the end
8.3 + 5.2 + 4.36 + 42.1 + 86.0 = 145.96
The least decimal place is the tenths place
so you should get 146.0
