1)一个是某人以固定利率A 投资和B 投资了20000刀,A=12.5 B=8.5 问你回报不少于2000的话,A 最大取多少. 不过问的好像是以B投资
答案:12500
解释:设投资A x刀,投资B (20000-x)刀。 0.125*x+0.085*(20000-x)=0.04x+1700>=2000
x>=7500 B最大取20000-7500=12500
2)一共有六本书,价钱都一样,一个人只有买三本书的钱。问可能有多少组合。
3)r/s是不是terminated decimal?
(1)r is a factor of 100,
(2)s is a factor of 100
4)Is 0 the remainder if (3^x)+1 is divided by 5?
1) x=4n+2
2) x>4
5) xy<1?
1) x+y>1
2) x^2+y^2=1
6)还有说7^m+1是除以5余数0?
1,m是4n+2
2,M是另一个什么反正是不行的
7)7^k 的十位數為 0 時, 請問 (I), (II), (III) 之選項何者為真 ?
(I) 7^k 的個位數為 1 (Possible, not sure ??)
(II) 7^k的各位数为5
(III) 7^k 可被 4 整除(是被3整除还是被 4 整除,我忘了)
A。IONLY
B。IIONLY
C。IIIONLY
D。I AND II(不是I和II就是II和III,不记得了)
E。I,II,III
这道题奇怪,我考时无NONE那个答案,搞了好久没懂,随便选了E

1. 建议大家看一下抛物线方程的表达.
好象题是这样:
P=dx²+ex+f,问能不能求D,E,F
1) p=0时,D,E,F 有值
2) 点取25时,P有最大点
2. 3 台机器同样的速度开,如2台同时开完成某任务要K小时,开3台要K-2小时,求K=?
3. a=1+1/4+1/16+1/64, b=1+1/4a , 求a-b=?
4. 14250立方毫米=?立方厘米
5. 问17除了17和1外有其他无因子
6. 某人周1周2周3,共3天中午吃饭花费平均6元,求中数
1) 周1中午吃饭花费5

7.小r=4,大R=6,2圆相切,求过2圆中心的直线斜率
ATH connecttype="rect" gradientshapeok="t" extrusionok="f">ATH>ATH connecttype="none" extrusionok="t">ATH>INE>INE>INE>INE>INE>INE>INE>INE>
8.好象是问X=Y时,直线是圆直径,还问V是否W ,忘了,但图是对的
8 ATH connecttype="none" extrusionok="t">ATH>
INE>INE>
作文如下:ARGUE
The following appeared in an Avia Airlines departmental memorandum.
“On average, 9 out of every 1,000 passengers who traveled on Avia Airlines last year filed a complaint about our baggage-handling procedures. This means that although some 1 percent of our passengers were unhappy with those procedures, the overwhelming majority were quite satisfied with them; thus it would appear that a review of the procedures is not important to our goal of maintaining or increasing the number of Avia’s passengers.

“We can learn more about a society by observing how its people spend their leisure time than by observing them at work.”
考的不好,才500多。考时没感觉了,特别是CR不知道在讲什么,为了赶速度凭感觉选一个。结果Verbal对了一半。
总结经验,休息一周准备再战。
PS ,今天AM上海考场4人考,一个外国MM考了700,一个学生MM也上了700,还有一个MM630,我最少。惨啦!!!!!!!! |
