**Choice G**

$$\frac{1}{4}=0.25 \\$$ $$ \Rightarrow 0.03 \leq 0.2 \leq 0.25 \\$$ $$ \Rightarrow 0.03 \leq 0.2 \leq \frac{1}{4}$$

**Choice H**

Since T and U bisect QR and QS, respectively, TU//RS. Thus, $$\angle TUQ=\angle S=60° \\$$ $$ \Rightarrow \angle TUS=180°-\angle TUQ=180°-60°=120°$$

**Choice K**

$$\sqrt{81}=9 \\ $$ $$\sqrt{99}\approx\sqrt{100}=10$$ $$ \\ 9 \leq 9.2371 \leq 10 \\$$ $$ \Rightarrow 81\leq the \ number \leq 99$$
