Answer:
4.
Explanation:
The answer is 952.2
There are 4 digits so the amount of sig figs is 4.
If you have two numbers, 593.00431 and 359.2, and we add them together, there will be four significant figures in the answer
In positional notation, significant figures refer to the digits in a number that are trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
Only the digits allowed by the measurement resolution are reliable, so only these can be significant figures if a number expressing the result of a measurement (such as length, pressure, volume, or mass) has more digits than the number of digits allowed by the measurement resolution.
A number is rounded off to the required number of significant digits by omitting one or more digits from the right. If the first digit in the left column is less than 5, the last digit retained shouldn't change. When the first digit exceeds 5, the last digit is rounded up. The retained number is rounded up or down to an even number when there are precisely five digits left. When there are numerous digits left, rounding off should be done as a whole rather than one digit at a time.
As given in the problem If you have two numbers, 593.00431 and 359.2, add them together
sum = 593.00431 +359.2
=952.20431
=952.2( significant figures)
The rightmost numbers starting from the 4 are not significant as per the rules of the significant figures
Thus,If you have two numbers, 593.00431 and 359.2, and we add them together, there will be four significant figures in the answer
