1.有3个integer r,s,t 这3个数除以5的余数是一样的,问t的值。 2.2^26除以6的reminder
2^26/6=2^25/3=(2^4)^6*2/3
2^4/3 余数是1, so the remainder is 2 为什么(2^4)^6可以直接考虑2^4?这题应该怎么考虑呢? 6.[z]is the greatest integer less than z. [z]=-1, z的范围 题目给的范围要比我们求的大,到时候只要选在其中的就行,选项我不记得了 Z<-1 是这个么:Z (-1,0) 7.a circle x^2+y^2=10,求在圆上有多少个整数点 8 +- 1, +-3
那应该是4个亚(1,3)(1,-3)(-1,3)(-1,-3) 9.一个公司购买个什么东西吧,成本是3美元的加工费再加上买产品的钱,单个产品价钱19.95,问产品的数量是多少?
(1)220<total cost<225 (2)<total cost< 后面一个不太记得了,反正两个数减3了再除那个单价的话一个是十点几,一个是九点几吧. ???? 10.a group, 44% are males,75% are athletes, 15%femal are not athletes. what is the percent of males who are athletes
62% 男,非运=25-15=10 男,运=44-10=34 所以34%?不懂。。。 sa009,你的62怎么算出来的呢? 11.一个公司买3种产品,成本和数量如下,假如公司都以80卖出,则gross profit is 40% of the cost. x=? number | cost | 20 | 60 | 10 | 55 | x | 30 | | |
(20+10+x)*80 = 1.4 *(60*20 +55*10+30x)è x=50/38
不懂 12.a school wants to improve the comprehensive ability of students. then it makes students to study English, French, German. 2students are exempt from three courses. 5students are exempt from learning E and F, 8 students are exempt from E and G, 3 are exempt from G and F. 36students are exempt from learning E,22 students are exempt from learning G, 15 are exempt from learning F, how many students are not exempt from learning . the total number is 100 中间的数字可能记得不太清楚,不过算出来应该是40 100 – [36+22+15-3-3-5+2] = 27
A+B+C-AB-BC-AC+ABC 100-(36+15+22-5-8-3+2)=41? 13.+is an ordinary additon. g+q=? (1)s+p=0(2)k=1
+ | a b c | d e g | g n s z k m p y q |
实际的图形没有外面那个框,只有中间一条竖线和横线,我不会画,就画了这个表 ???
s=c+d,p=a+g, s+p=c+d+a+g=0 and you can find g+q=a+d+c+g=0, so I choose A 14. which fraction has definite decimal number A.1/(2^2 5^3)B.1/(2^3 3^4)
具体数值不是太记得了,只知道有四个选项分母里面都有3的几次方 A 这题什么意思啊?A和B算出来都是由小数点的亚?
