?、献上狗狗：
AA: 224范文34题、
34. The following appeared as part of a plan proposed by an executive of the Easy Credit Company to the president.
“The Easy Credit Company would gain an advantage over competing credit card services if we were to donate a portion of the proceeds from the use of our cards to a well-known environmental organization in exchange for the use of its symbol or logo on our card. Since a recent poll shows that a large percentage of the public is concerned about environmental issues, this policy would attract new customers, increase use among existing customers, and enable us to charge interest rates that are higher than the lowest ones available.”
Discuss how well reasoned... etc.
AI:在224里没找到，不知道是不是新的~
Public figures should avoid expressing opinions about things they have no experiences or been directly affected by.
数学狗狗：
(1) 【和寂静33题差不多】PS:一个圆柱体tank,height=4feet底面圆周长=4pi,现在以3feet/min速度往里面注水,问：圆柱里的水满1/3和全满(full tank)时相差了 多少时间?
选项有5，11，17...
我的答案：(4pi*4)/3-[4pi*4*(1/3)]≈11
(2)【寂静220题】PS:斜邊斜率為7/24，已知高為14, 求斜邊長度為? 原JJ斜率好像反了~
答案：50
(3)【补充寂静239】DS: 数字[(997)(103)]/x,What's the thousandth unit?
条件1：the tenth unit of x is 8;
条件2：80<=x<90
(4)【补充寂静332】DS: 两个数列x和y的合集共30个数range是25，问x range>25?
条件1：y有12个数，并且range是20
条件2：x有18个数
我选了E~
(5)【MS寂静里没看到】PS: 893×78=p,问下面哪个等于893×79？
答案：p+893
?、最后：
希望2010的Cders 都能顺顺利利实现自己的dream~
