Let's check every option to see which ones make the inequality true:
[tex]\begin{gathered} 6b\ge33 \\ \\ 6(\frac{5}{9})\ge33\rightarrow3.33\ge33\Rightarrow\frac{5}{9}✘ \\ \\ 6(5)\ge33\rightarrow30\ge33\Rightarrow5✘ \\ \\ 6(512)\ge33\rightarrow3072\ge33\Rightarrow33✔ \\ \\ 6(5.6)\ge33\rightarrow33.6\ge33\Rightarrow5.6✔ \end{gathered}[/tex]This way, the correct answers are C and D
