Respuesta :
18.2m has the least amount of significant figures (3) so the final product should have that many significant figures. After adding all of the numbers together you get 46.217 m but we need 3 significant figures for this problem so you simply round it to 46.2 m
Answer : The correct answer will be 46.2 m.
Explanation :
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the addition and subtraction is :
The least precise number present after the decimal point determines the number of significant figures in the answer.
Given : The sum of the measured values 11.074 m, 18.2 m, and 16.943 m.
[tex]11.074m+18.2m+16.943m[/tex]
[tex]\Rightarrow 46.217m[/tex]
In the given expression, 11.074 has 5 significant figures, 18.2 has 3 significant figures and 16.943 has 5 significant figures. From this we conclude that least precise number present after the decimal point is 1.
Thus, the answer will be 46.2 m.
