4 yards or less,flat fare $18;more than 4 yards $4 each,sell to T and R all together$70 how many yards to R? (1) T $52 (2) all together 15 yards 注意 之前机经题目提供有误 我确定题目是这个 4 yards以下都交18块 所以根据(1)不能推出R买了多少yards 因为有可能是1 2 3 4任意一种 根据(2)可以求得15-52/4=2 选B
is 1/(p*q) a decimal representaion with finit nonzero figures to ritht of the decimal point (1) p=5^n (2) q=3^n 我选的(1)+(2) 这个题目我怎么总觉得是B呢,只要分母有3就是无限循环的结果了,有5的话也一定能被除净啊
