课堂作业八年级下册数学答案

What (be) five and six? It(be) eleven. 填写 设计R中=10KΩ的欧姆表,现有两块量程100μA 的电流表,其内阻分别为2500Ω和1000ΩRT~你认为选哪块较好~ 欧姆表的量程决定于什么 电源电压 还是电流表的量程?内部构造中 有一个电源和滑动变阻器呀 就是说 表本身的量程 是取决于内部电源电压还是与之连接的表头的量程大小？或者简单来说1.1 制作一个量程为100 欧姆 1000欧姆 10K欧姆 10M欧姆的三位显示电阻表三档自动量程转换功能 求3月10日托福小马机经（阅读+听力+口语+写作）,如果有新东方机经追加金币. 09年托福机经+08、09托福阅读听力加试 2013年1月份托福机经!小马机经最好,大范围1月的机经.要是有小范围更好了,1月26日、27日的! 求小马过河6—8月托福机经V9.0 口语写作听力阅读,邮箱secihuang@sina.com.如果有别的版本的机经一起发吧 英汉互译4.第2课（英语）用适当的数词填空5.Three and five is( ).6.Eight minus four is( )7.There are（ ）minutes in an hour.8.There are ( )days in January.6:20(英语）1:50（英语）12:45（英语）3:30（英语）单项选择9.W She was so sad that she spent the whole day___in her own roomA.locked B.locking C.to lock D.to be locked she （v.）to work in the hospital to help the sick people 第二单元的单词)大神求教 努力跟上你的步伐 用英语怎么说rt、 jim is doing a homework p______ in his room play doing in in the his garden room is his homework he or 连词成句 Fred is in his room.He is doing his homework."Homework isn't nice,"he says to Tiger."Tiger is my friend,"he writes."He is my cat.He is small and his eyes are green.I give him fish and milk."Tiger looks at Fred."Fish?Milk?"Fred says,"I can't come now. im is in his room.He is doing his homework Homework isn't nice ,"he say to Tiger ."T."Tiger is my friend,"he writes."He is my cat.He is small and black and his eyes are green.
