Three significant figures: two before the decimal point and one after.
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.
To match measurements to the correct number of significant figures, you must consider the precision of each value. For example, a measurement like 0.00456 has three significant figures (4, 5, and 6), while 1200 has two significant figures if no decimal is present. In contrast, 1200.0 would have five significant figures due to the decimal indicating that the zeros are significant. Always look for non-zero digits, zeros between significant figures, and trailing zeros with a decimal point to determine the total count.
A triple beam balance typically allows for three significant figures in its measurements. The first two significant figures are determined by the position of the sliding weights on the beams, while the third can often be estimated by observing the balance's pointer. Therefore, when reading the scale, users can confidently report measurements to three significant figures. However, the precision may vary depending on the specific design and calibration of the balance.
3 significant figures.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
0.01223 contains 4 significant figures1.01 contains 3 significant figures
It is then 2.64 when rounded to three significant figures
Three significant figures: two before the decimal point and one after.
3 significant figures
There are 4 of them
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.
