Answer:
C
Step-by-step explanation:
1. π ≈ 3.1415. π + 10 ≈ 13.1415.
2. Find the square root of 20. It is about 4.4721. 4.4721 + 1/2 (or .5) = 4.9721
3. The square root of 100 is 10.
4. Order them.
5. It is most obvious that the answer to [tex]\sqrt{20\\}[/tex] + 1/2 is first. The square root of 100 is ten, so that goes second because pi + 10 is greater than 10. (pi + 10 goes last)
6. [tex]\sqrt{12} + 1/2, \sqrt{100}, \pi + 10[/tex]
