C 2
D 1/2
第二道——When 15 is divided by the positive integer k,the remainder is 3,.For how many different values of K is the true?我觉得是4个（1,2,3,4）,但答案给的是3个,为什么,哪里错了?

第一道
C
直径是一半,所以周长是一半,所以要走相同的距离要有2倍的转速.
第二道
15被一个正整数除余3,所以这个数12的因数.所以可以是4,6,12.总共3个.

有没有SAT II数学8，物理，化学的资料？我没上过课，不太了解。要是有对于中国学生的基础来说没问题的 你所写的我都有考过。只要你高中的

那个第二题余数是3，所以12能整除这个k
并且这个k要大于3
那么k只能取4、6、12了
所以有3个
第一个是c么，一个直径是一个的一半，则一个周长就是一个的一半，那么一个转一圈，另一个就转两圈撒
