Answer:
Explanation:
The correct number of significant figures in the number 1.250100 can be determined by identifying the digits that are certain and significant in the measurement.
Significant figures are the digits that carry meaningful information in a number.
In the number 1.250100:
- The digits 1, 2, 5, and 1 are all non-zero digits, so they are significant.
- The zeros between the non-zero digits, such as the zeros between the 5 and 1, are also significant.
- However, the zeros to the right of the decimal point, such as the zeros after the last 1, may or may not be significant. It depends on whether they are placeholders or carry meaningful information.
In this case, the zeros to the right of the decimal point are significant because they are present after a non-zero digit.
Therefore, the correct number of significant figures in the number 1.250100 is 7.
In summary, the correct answer is B) 7.
