When measurements are expressed to three significant figures, it means that only the first three digits that contribute to the precision of the number are considered. This includes all non-zero digits, any zeros between them, and trailing zeros if they are to the right of a decimal point. For example, the number 0.00456 would be expressed as 4.56 × 10^(-3) in three significant figures. This practice helps in maintaining clarity and consistency in data representation.

What is the measurement that has been expressed to three significant figure is?
A measurement expressed to three significant figures includes three digits that contribute to its precision, which may include leading zeros but excludes trailing zeros unless they are after a decimal point. For example, the number 0.00456 would be expressed as 4.56 × 10^-3 in three significant figures. Similarly, a measurement like 1500 could be expressed as 1.50 × 10^3 if it is intended to be three significant figures.

In adding the measurements 11.074m 18.2m and 16.943m what should be the number of significant figures in the result?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Is 7.30 by 10 -7 km expressed to three significant figures?
Yes.
What is the number of days in a year expressed in scientific notation with three significant figures?
The number of days in a year is approximately 365.25. In scientific notation with three significant figures, this can be expressed as 3.65 x 10^2 days.

The mass of an object was recorded as 9.93 g 9.90 g and 10.02 g using an electronic analytic balance. What is the average of these three masses expressed to the correct number of significant figures?
To find the average of the three masses (9.93 g, 9.90 g, and 10.02 g), first sum the values: 9.93 + 9.90 + 10.02 = 29.85 g. Next, divide by the number of measurements: 29.85 g / 3 = 9.95 g. Since the least precise measurement (9.90 g) has three significant figures, the average should also be expressed to three significant figures, resulting in an average mass of 9.95 g.
How many significant figures are in 36.7?
