Answer:
The square roots of 144 are 12 and -12 which are rational numbers.
Step-by-step explanation:
The obvious one is (310 beats)/(1 minute).
1. Balance after 1 year with simple interest= 600 + (2.5 x 12) = 600 + 30 = $630
2. Balance after 1 year with compounded interest = P ( 1 + 

= 600 ( 1 + 
= 600 (1.0511) = $630.66 = approx. $630
1. 12-9×3×4+3=-93
2.3+4×3×9-12=99
3. 12-9+3×9×3×4=327
I think the correct answer is 17
