数学很多都是JJ,大家一定要仔细看JJ,不要只记得答案——要懂得方法!因为我看到一些和JJ类似的题目,方法一样,但是条件和数字换了,所以大家一定要小心审题!今天很幸运,没有遇到什么排列组合的题,DS的题也比上次少!
1.JJ有题是:x/3在3和100间,且是一个素数的平方,这样的x有几个?
今天考试遇到的,变成:3<X<100, 问x能取什么值以使X/3是质数的平方。
2.一个容器还是什么的,给出表达式Q(t)=-(t-5)^2+3,告诉这个液体流出的时间t hours是在2点钟的时候开始流,问Q(t)的最大值时,表上的时间是多少。
3.JJ61.
电影票A类单价4.5元,B类单价6元,其中一场售出的电影票中60%不是A类,问不是A类票的销售占总收入比。
4. JJ50. 一个类似于操场跑道的形状,两个半圆夹一个长方形,告诉直线的距离长,以及长方形面积等于两个半圆型面积和,问长方形另一边的距离
5.JJ S=1/32 + 1/33 + ... +1/64,问S所在的范围那题
6.JJ319. 98年比97年的的收入上升了X PERCENT,然后99年比98年有下降了X PERCENT,而且比99年比97年少了9%,求X。
7.有一题问X的百位数是多少,前提是给出x的一个等式。条件1不记得了,只记得条件2说四舍五入后得出2600,而这个条件是不充分的,因为2599可以四舍五入得2600,2601也可以得出这个结论。我最后选A。
Verbal,我没看过这个月verbal的JJ,所以只能说说我记得的RC,考了一篇讲work hour regulation的,说male worker赞成这个立法因为它会促使雇主雇佣更多的men,而女权主义者因为相同的原因(雇佣更多的men)而反对立法(——有问两者对这个的态度如何)。然后解释了这个立法不会如他们预期的那样削减了女性被雇佣的机会。还考了一篇生物的,说有个人出了一本书,新解释了organism是怎样形成的,有三种molecule起了motivate、connect和communication的作用。
AWA,写的时候感觉没上次得心应手……
Argument:
125. The following appeared as part of the business plan of the Capital Idea investment firm.
“Across town in the Park Hill district, the Thespian Theater, Pizzazz Pizza, and the Niblick Golf Club have all had business increases within the past two years. Capital Idea should therefore invest in the Roxy Playhouse, the Slice-o’-Pizza, and the Divot Golf Club, three new businesses in the Irongate district. As a condition, we should require them to participate in a special program: Any customer who patronizes two of the businesses will receive a substantial discount at the third. By motivating customers to patronize all three, we will thus contribute to the profitability of each and maximize our return.”
Issue:
132. “Governments should not be responsible for regulating businesses and other organizations. Instead, society would benefit if the organizations themselves assumed responsibility for establishing and enforcing their own standards and regulations.”
只记得这么多了……希望对大家有帮助啦^_^
祝愿未来要考的xdjm取得理想成绩吖
