7 sigfigs
It has 4. Every 0 after a decimal and after a significant digit is significant.
There are 3 sigfigs in 100. because there is a decimal after the second zero, indicating that the units digit matters. If there is no decimal place, then the zeros are considered place holders and thus would be 1 sig fig only. But since there is a decimal, the former is true.
To convert from kilometres to metres, you multiply by 1000 because there are 1000 metres in 1 kilometre.Therefore, you would convert 50 kilometres as follows:50 x 1000 = 50 00050 kilometres = 50 000 metres
Scientific notation is useful because it helps to read values' significant figures (sigfigs). For example, the number: 6.02^(-10) is much easier to read than .000000000602. When dealing with especially large or small quantities, scientific notation makes it easier to understand how big or small the quantity is.
Five.
if you write it as 1200. (with the decimal) it will have 4 sigfigs.. or it can have 2 sigfigs (12) - im trying to get 3 sigfigs.. that's my hw but i cant get it yet
7 sigfigs
5 of them.
The compatible spark plug is numbered 791-610311B. The spark plug body may have 794-00050 on it.
It has 4. Every 0 after a decimal and after a significant digit is significant.
you'll notice that there is a decimal, and a zero after the decimal, meaning that the number of sigfigs equals the number of digits: 8
The first calculation has 3 significant figures as all numbers included in the calculation are whole numbers. For the second calculation, since there are only 3 significant figures in 10400mi and 328102hr, the answer should have 3 significant figures as well.
2. The 6 and the 3 are both sigfigs. Since there's no decimal point, the other zeros are placeholders and therefore not important.

two. Here are some rules for determining sigfigs:Digits from 1-9 are always significant.Zeros between two other significant figures are always significantOne or more additional zeros to the right of both the decimal place and another significant figure are significant.Zeros used solely for spacing the decimal point (placeholders) are not significant.eg.NUMBER SIG FIGS EXPLANATION453 kg3All non-zero digits are always significant.5057 L4Zeros between 2 sigfigs are significant.5.003Additional zeros to the right of decimal and a sigfigs are significant.0.0071Placeholders are not significant
