这次数学TM难!!! 希望这些狗多少能帮助到要上考场的各位…. 下面就中英交杂一下 DS 给一个方程式 y=ax^2+bx+c 问有没有经过X轴 条件忘了 DS 类似这种的绝对值比大小 IS |x+y|<|x|+|y| ?? 1)xy<0 2)x+y<0
DS: if there's 5 numbers how can you deternime the median of these numbers? 1) 3 of the numbers are 3 5 8 2) x>z PS 给一个方程式 y=ax^2+bx+c(没办法用整数拆开) 问平方根是多少 用公式拆开就能解 PS someone is walking from his home to office and the total distance is 1mile, if this person walk as the rate x+ 20 then he will arrive his office 4min earlier than original rate. What is his original rate? DS is x/y > a/b? 1) x>a 2) a>b I am not sure about the condition but the question should be right PS: if a cylinder with circumference 2π and 27 ml water is filling into this cylinder in x min,(x known but I forgot) , what's the rate of filling? 然後以下两种题型至少都各出两题
- A is 2 time B and is 4 times C. what is the rate/what is the number….
- the percentage problem comes often , For example...
the percentage of girls who have a car is xx % the percantage of boys who have a car is oo% if the total number of people in this survey is $$$ . how many girls DO NOT have a car?
阅读部分, 我记得多少就讲多少. 几乎我碰到每一篇都问我primary purpose, 幸好都没问我except不然我真的要发疯
1. downsize 这篇文章有考到. 2. 对於hispanic这个称谓不再代表西班牙後裔, 而是被广泛使用在其他族群之间, 做为一种代名词. 文章第一段解释了hispanic这个字以前跟现在的意义. 第二段忘记说什麽了, 第三段就讲了american indian 这个字的解释. 估计应该也是跟hispanic有关系. 问题问了(1)primary purpose (2) 作者举第三段american indian 的例子是要表达什麽? (3) 以下哪个可以被推知为作者同意的叙述? 3. 两种蝴蝶. A蝴蝶会去吃B蝴蝶的卵(还是恶搞人家的卵什麽的) . 当其中一种做出某种行为的时候, 另外一种也会演化出某种行为来相克. 第二段跟第三段大概就在讲他们彼此的行为... 问题问了 (1) Primary purpose (2) 第三段里面某个名词/行为所代表的意义
逻辑有点记不清...明天想想再来看看有没有能放的
