题目没看懂,大虾们指点一下~~~~ In a certain coding scheme, each word is encoded by replacing each letter in the word with another letter. The same code is used for all words, so that the same letter replaces a given letter each time the given letter occurs. What code will result when the word TAME is encoded by this scheme? (1) When the word MAT is encoded, the result is DLX (2) When the word TEA is encoded, the result is XRL. Answer:C 呵呵,再问两道对答案有异议的题哦~~~ 1.The price of a telecisions set was reduced by 25 percent. What was its original price? (1) The reduced price was $187.5 (2) The original price exceeded the reduced price by more than $60.00 Answer:A 有第二个条件和题目已知可以列出一个一元二次方程组阿?? 所以(2)也可以阿? 下面这道题觉得答案有误,麻烦大家给确定一下哈~~~ 2.A 2-year certificate of deposit is purchased for k dollars.If the certificate earns interest at an annual rate of 6 percent compounded quarterly, Which of the following represents the value, in dollars, of the certificate at the end of the 2 years? Answer: (1.03)^4*k quarterly 不是每季度么?那应该将interest rate 除以 4 才对啊? 答案怎么除以2阿?而且两年应该是^8吧? 谢谢大家~~~  |
