Answer: 11.8 meters .
___________
Step-by-step explanation:
We are asked to add the following values together:
6.75 m + 5.003 m ;
Let's assume that both values are experimentally obtained values; as such, we shall add these together and then obtain the result —by using the lowest number of significant figures [also known as 'significant digits' .
Since 6.75 has 3 (three) significant figures; and since 5.003 has 4 (four) significant figures; we shall add both values together and then determine the value with 3 (three) significant figures.
Note that both given values are the same units of measurement, that is, "m" (for 'meters').
5.003 m
+ 6.75 m
11 .75 m ← This value has 4 (four) significant figures.
We can round this up to 11.8 m ;
Since the number after the digit 7 is 5; and if the digit is 5 to 8, we round up. Since the digit is 5, we round the number following the 7 digit, in the 11.75 calculated value, to 8.
