In adding the measurements 11.075m 18.2m and 16.943m what should be the number of significant figures in result?
Forget about "significant figures"; those are used to determine the precision when you multiply or divide. When adding numbers, the rule is that the result should be rounded according to the precision of the least accurate of the addents. In this case, to one decimal digit.
What is the rule for significant figures when adding or subtracting decimals?
When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
What is the significant figures of the number of 23.400?
There are five significant figures in the given value. It is according to the rule of significant figures which say that zeros right to the decimal point are significant and all non zero digits are significant So , all the digits in the given value are significant figures i.e 5 significant figures.
How many significant figures are in 0.041?
There are 2 because of the leading zeros rule. Zeros at the beginning of a number are never significant.
What are slide rule's disadvantages?
The main disadvantage is that in may cases the level of precision is limited to three significant figures.

What is the rule you use to determine the number of significant figures in the results of addition and subtraction?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

What is the rule about significant figures when multiplying or dividing measurement?
the decimal place in the quotient or product should be based in the decimal place of the given with the least significant figures
How many significant figures are in 0.041?
There are 2 because of the leading zeros rule. Zeros at the beginning of a number are never significant.
How do you round 2231479 to four significant figures?
The significant figures are the first four non-zero digits - with the last of these adjusted if the following digit is 5 or more. [This is the crude school rule rather than the bias-free, IEEE approved rule.] So the answer is 2231000.
What is the Rule about significant figures when adding or subtracting measurements?
For multiplication and division, you keep the number of significant figures (sig figs) that were in the number with the lesser number of figures. For example, 12345 divided by 555 on a calculator gives 22.243243... but you would represent this as 22.2 because 555 has only 3 sig figs. That said, sig figs are a bit silly in that 99 is much more significant than 10, though both have two digits. Going from 99 to 100 is a 1% change, but going from 10 to 11 is a 10% change. When doing calculations, you should in general NOT round intermediate answers to sig figs, but only the final answer. It's usually best if possible to do the calculation symbolically (such as X is the number instead of 12345) and solve for your final answer, and THEN do all the calculations at once on a calculator, rather than writing down lots of intermediate values (and rounding many out of laziness.) Alternatively, do the calculations in a spreadsheet where you can show all intermediate numbers but preserve them to their full significance, and be able to check your work, unlike with most calculators.
How many significant figures are in 14 plus 3.078?
Take the least number of decimal places when adding or subtracting, therefore the answer is 17 to no decimal places.If it was 14 x 3.078 the answer would be 43 to 2 significant figures. The rule for multiplication/division is to use the least number of sig figs in the components: 14 has 2 and 3.078 has 4 so the answer should use 2.
When you add or subtract what is the rule for determining the number of significant figures in the answer?
= significant figures = and got For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places.

The main disadvantage is that in may cases the level of precision is limited to three significant figures.
How many significant figures are in 9.090?
If the zeros are significant figures then 900 is correct to 3 significant figures. If rounding off has occurred then the answer could be 1 sf or 2sf. For example : If the original number was 903 and rounding off to the nearest ten was required then 900 is correct to 2 significant figures. If the number was 927 and rounding off to the nearest hundred was required then 900 is correct to 1 significant figure.
