Final answer:
In the given options, the number in which all of the zeros are significant is 100.090090.
Step-by-step explanation:
The zeros in a number are significant except when they serve only as placekeepers. Therefore, in order to determine which of the given numbers have all significant zeros, we need to analyze each number individually:
A. 0.05843 - The zeros after the decimal point in this number are significant, as they indicate the precision of the measurement. Therefore, all of the zeros in this number are significant.
B. 0.1000 - In this number, the zero before the decimal point is a placekeeper and not significant. However, the zeros after the decimal point are significant. So, not all of the zeros in this number are significant.
C. 100.090090 - All of the zeros in this number are significant because they are not placekeepers, and they indicate the precision of the measurement.
D. 0.143290 - In this number, the zero after the decimal point is significant, but the zeros before the decimal point are placekeepers and not significant. Therefore, not all of the zeros in this number are significant.
E. 00.0030020 - All of the zeros in this number are significant because they are not placekeepers, and they indicate the precision of the measurement.
Based on this analysis, the number in which all of the zeros are significant is 100.090090 (option C).
