是这两题吗？结果是自己做的，如果有不同意见，可以提出来啊！谢谢。

114. 通过一个不等式可以推出k>8。问k的值：
1）k是<12的奇数
2）k是<12的质数
            

选B（k=11）
        

115. 某人工作的前4小时可以得到报酬r，4小时之后每多1小时报酬增加0.4r，问某人工作了多少小时
1）某人一共得到$480；
2）某人超时部分的报酬是40r
（具体数字不记得，大概是这个意思）
            

我选B

112. 3/根号（0.63）+46/9 最接近下面哪个数：5；6；7；8；9  我选9

I think this should be 6

Why?

3/根号（0.63）+46/9 =3.75+5.1=8.85,

you mean 8.85 is closer to 6 than to 9?

well, I read the question to be (0.63)^(1/3) + 46/9
