下面是参加了海外gre数学机经的同学分享的gre数学机经,希望通过自己的分析和解答能给其他gre考生提供思路和指导,也可以和周边的g友一起来讨论这些题目,对于gre数学考试的复习是相当有帮助的。
36、PS 一个什么运动从比一个村庄海拔高850/580feet的地方开始,分5段,分别告诉你每段ascent或者descet多少feet,问最后到终点那个地方和村庄海拔比差多少。 很简单的加减法,最后算出来是0,即和村庄在一个海拔。 题目不是很全~抱歉~~
37、DS 2y-x=x^2-y^2 问的啥我忘了||| 题目不全
38 、PS 我的最后一题,说n是偶数,问下面那个是偶数 a, /4 b, n^2/4+4 c, n^2/4
a, /4 b, n^2/4+4 c, n^2/4
a =n2/4 + 1
b =n2/4 + 4
c =n2/4
n2/4奇偶未定, 比如n=2时为奇, n=4时为偶,故为none
39 、DS 一个三角形,问你它的面积是什么? 1)周长是X^2-4X+4=0 2) 高是2cm DS 一个等腰直角三角形,问你它的面积是什么? 1)周长是X^2-4X-4=0 2) 斜边是2cm 确定用的词是hypotenuse 我选的D,等腰直角神马的,最喜欢了
条件1)X^2-4X+4=2=0可得知周长x=2 无法求得面积
条件2)h=2 无法求得面积 条件1)+ 条件2) 无法求得面积 选E
条件1)X2-4X-4=0得知周长x=2+22 根据等腰直角三角形三边之比为1:1: 2可得知
边长,从而求得面积 成立
条件2)根据等腰直角三角形三边之比为1:1: 2且斜边=2可得知边长,从而求得面积 选D
40 、好像是A,B,C工作分别用4,5,10分钟完成一个TASK,然后现在说A先做了一分钟,问你剩下的由B和C做,要多少分钟。
A,B,C一分钟的效率分别是 1/4,1/5,1/10 剩下时间为 /=2.5min
接下来的几天我们还会给大家分享g友的gre数学机经,希望gre考生能把这些题目都弄懂,弄明白,这样在应对gre数学考试部分的时候也会迅速作答。
