1.列式计算：王洪在计算除法时,把除数54写成45,结果得到的商是25余9正确的商应该是几
（45*25+9）/54=21
2.填空3X0.4表示（ 3的十分之四是多少）五分之三表示（把1分五份取其中三份） 还可以表示（三个五分之一 ）
A=五分之四xB=Cx75%=E÷三分之二=D÷一又二分之一
把ABCDE按从小到大顺序排列E

比例尺=图上距离/实地距离
设比例尺为1:100（即图上1cm相当于实际100m）
张华：王洪：李明（距离）=9:8:4
他们在图上的距离：
张华：1/100=x/450 x=4.5cm
王洪：4cm
李明：2cm

Dear David,
How is everything going?Have you already finished the final exam?
From next week on,I don't need to go to school any more,and I can't wait to welcome the coming winter vacation!
What I'm thinking is relaxing myself and having a good rest,like maybe reading some books,or watching TV.My mom would be happy if I do the chores.What's more,I will hang out with friends and enjoy the time with them.
Actually immediately comes the Spring Festival,the eve of which for Chinese is a meaningful night.In that night we entire family will enjoy the delicious and abundant dinner and watch TV shows together.Of course the brilliant fireworks!A harmouious and peaceful night is the favorite of everybody here.
And you?What's in your plan?Looking forward to you reply!
Best wishes,
Yours
Wang Hong

解题思路：使用定滑轮时，不省力，也不省距离，能改变力的方向；动滑轮使用特点是：拉力是物体和动滑轮重力的一半，但费距离；
有用功等于克服物体自身重力所做的功；不计绳重和摩擦，克服动滑轮的重做的功就是额外功．

在定滑轮上，F_甲=G；在动滑轮上，F_乙=
G+G动
2，则
W_甲=F_甲s_甲=Gh，W_乙=F_乙s_乙=
G+G动
2×2h=（G+G_动）h；
故W_甲＜W_乙．
将两个重量相同的物体匀速提升相同高度，说明有用功是相等的，使用动滑轮时要克服动滑轮的重力做额外功，所以η_甲＞η_乙．
故选C．

点评：
本题考点： 功的大小比较；滑轮（组）的机械效率．

考点点评： 本题考查动滑轮和定滑轮拉力、移动距离、有用功、总功和机械效率的大小比较，关键是掌握它们的工作特点．

你教他做题思路.然后让他自己想
你去他家,给他补习功课
你要劝阻他.如果不管用,就告家长或老师让他们来帮助他

Hi David,
How are you?Nice to hear from you again.

其他麻烦自己找吧,

Wang Hong is a friendly girl and has a lot of hobbies. She often helps her parents with the housework. It’s her birthday this Saturday. Many classmates will go to her home for her birthday party. Some of them will ask their parents for some money to buy her gifts. But I don’t think it’s a good idea, because that’ll cost our parents’ money. I’m going to make a birthday card for her by myself. I’m sure she’ll like it.

Hello,David,I'm WangHong.First,I'm going to watch TV .Then,I'm going to do my homework.Then,I'm going to light fireworks.I'm going to be happy in winter holiday.

2500x(1+2.89%*3)=2716.75元
到期时他可以获得本金和利息一共2716.75元

就是你现在遇到的人并不是你的有缘人,不管周围的人和你说过些什么都不可尽信.置于你的姻缘等等自会到的.

Dear David,
Nice to hear from you. Here is my plan for the winter holiday. First, I will do my homework every day because I have a lot of homework to do. In this way, i can go over my lessons. Second, I will do some reading. I have bought three favourite books, which are very interesting. Third, at night, i will watch my favourite TV programme ,such as NBA, Big Brothers. Of course, I will play basketball with my friends every afternoon. I have a new basketball. So I believer my winter holiday will be very interesting and meaningfu. I am looking forward to the Spring Festival too.
Best Wishes,
Yours,
Wang Hong.
我自己写的,仅供参考啊!

设第一次存款时的年利率为x,
根据题意,得［100（1＋x）－50］（1＋ x）＝63．
整理,得50x2＋125x－13＝0．
解得x1＝ ,x2＝－ ．
∵x2＝－ 不合题意,
∴x＝ ＝10％．
答：第一次存款时的年利率为10％．

王：（47+49+50+53+51+49+48+51+52+50）÷10=500÷10=50
李：（41+52+59+48+50+57+51+58+41+43 ）÷10=500÷10=50

解;她一小时走了这段路的四分之一,3小时走了这段路的四分之三.

每个选项可以设置,如果你这么推论,ABCD.影响学生的政策问题,开创自己的事业,没有足够的企业.D是说是西方的学生喜欢挑战不敢.每一个选项都有一定道理的.
但最终只能选择一个选项,选项,选择必然性的质疑.的政策是不推不肯定不低,B项基数大的推动,而不是实际的一些小D样的挑战,也将推动企业肯定不会到低.只有C项是西方大学的学生的成功率很低,没有真正能够证明,这是必要的.
以上回答你满意么?
