significant figures make data analysis less ambiguous and therefore much easier..

It only has 3 significant figures, 863.
5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)
39
All five of them
Significant figures are important in measurement because they determine how accurate a scientific claim can be. There always has to be a small amount of uncertainty in an answer, because no measurement or calculation is ever 100% absolute.

4 significant figures.
There are 3 significant figures in 94.2.
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
There are four significant figures in 0.1111.
20.2 has three significant figures.
There are two significant figures in 0.025.
5 significant figures.
Trailing zeros ALWAYS count as significant figures, so 700.0 would have 4 significant figures.
That depends on how many significant figures you are talking about.If three significant figures then 700 is the largest that rounds to 700.If four significant figures are to be rounded to three significant figures then 700.4If five significant figures are to be rounded to three significant figures then 700.49If six significant figures are to be rounded to three significant figures then 700.499etc.
There are four significant figures in .007001
The number 30.4 has THREE significant figures.
