A decminal place is simply the number of digits to the right of the decimal in a number. For instance, 37.5834 has four decimal places. In contrast, a significant figure is the number of digits on either side of the decimal place that can be counted as accurate in a calculation. Significant figures are used to determine how accurate a calculation is based on how accurate the measurements are. Significant figures are determined by counting the number of significant figures in the numbers given in a problem (usually in chemistry or physics) then using the lowest count found. Here's an example: "calculate the average velocity of a car that has travelled 45 km in 60 minutes." The number "45" has two significant figures while the number "60" has one significant figure. Therefore, when calculating the velocity (45/60), the answer can have only one significant figure: 0.8 km/min. However, if the time was written as "60.0" minutes, then this number would have three significant figures and the answer could have two significant figures (0.75 km/min) because the number "45" had two significant figures.

It is the digit 2

Yes.

12.56 km

1,000 m = 1 km If there is not decimal point at the end of 1000. it is just 1km. If there is a decimal point the correct significant figures would be 1.000 km

4 of them.

1,079,252,848 km/h or 299,792,457.8m/s

Answer: 546 mi. = 878.701 km

48,28 km.48 km (significant figures) 30.00 miles is 48.28 km

1km = 0.62mi 71km/h x 0.62mi/km = 44mi/h (44.02 rounded to two significant figures)

4,777 km

1333 km

Assuming the final zero is not there for decorative purposes, 6 sig figs.

The sum is: 1333 km
