Question

Calculate the answer to the correct number of significant digits. (87020)/(-6.92).

Answer 1

When dividing 87020 by -6.92, the answer, rounded to the correct number of significant digits, is -12500.

Step-by-step explanation:

When performing the calculation (87020)/(-6.92), we need to consider the significant digits in the numbers involved. The number 87020 has five significant digits, while -6.92 has three significant digits. The division of these two numbers will result in a value with three significant digits:

1. Divide 87020 by 6.92: -12571.6763...
2. Rounded to three significant digits: -12500

Therefore, the answer to the calculation, rounded to the correct number of significant digits, is -12500.

Answer 2

To find the quotient of 87020 divided by -6.92 with the appropriate number of significant digits, we divide to get -12575.4335..., then round to three significant figures, resulting in -12580.

Step-by-step explanation:

To calculate the division of 87020 by -6.92 and express the answer with the correct number of significant digits, we first perform the division using a calculator or a similar computational tool.

The raw calculator answer is -12575.4335..., but we need to round this to the appropriate number of significant figures. The number 87020 has four significant digits (the trailing zeros count because they are between significant numbers), and the divisor -6.92 has three significant digits. Therefore, the answer should be rounded to three significant figures. The rounded answer is -12580. Note that negative signs do not count as significant figures.
