第12讲 用假设法解题

第12讲 用假设法解题

第十二讲用假设法解题【专题解析】假设是数学中思考问题的一常见的方法,有些应用题乍看很难求出答案,但是如果我们合理地进行假设,往往会使问题得到解决。

所谓假设法就是依照已知条件进行推算,根据数量上出现的矛盾,作适当的调整,从而找到正确答案。

我国古代趣题“鸡兔同笼”就是运用假设法解决问题的一个范例。

【例题精讲】例1:鸡、兔共30只,共有脚84只。

鸡、兔各有多少只?【思路导航】方法一:列表法鸡的只数兔的只数脚的总数15 15 15×2+15×4=9016 14 16×2+14×4=8817 13 17×2+13×4=8618 12 18×2+12×4=84所以,共有兔子12只,有鸡18只。

通过图表可以发现,把一只兔子变成鸡,总脚数会减少2只。

故可以用假设法:方法二:假设法假设全是鸡,共有脚:30×2=60(只);比实际少:84-60=24(只);这是因为把4只脚的兔子都按2只脚的鸡计算了。

每把一只兔子算作一只鸡,少算:4-2=2(只)脚,现在共少算了24只脚,说明把:24÷2=12(只)兔子按鸡算了。

所以,共有兔子12只,有鸡30-12=18(只)。

【练习】1、鸡兔同笼,共有头48个,脚132只,鸡和兔各有多少只?2、一个饲养组一共养鸡、兔共50只,共有脚160只。

饲养组养鸡、兔各几只?例2:小邮迷郑渊用10元钱正好买了20分和50分的邮票共35枚,这两种邮票各买了多少枚?【思路导航】方法一:列表法方法二:假设法:假设35枚邮票全部是20分的,那么一共用了20×35=700(分)。

与实际用的钱数相差1000-700=300(分)。

将一枚50分的邮票看成20分的少算了50-20=30(分),故50分邮票有300÷30=10(枚),20分的邮票有35-10=25(枚)。

【练习】1、刘杰用13元6角钱正好买了50分和80分的邮票共计20枚,求两种邮票各买了多少枚?2、小红的储蓄罐里共有2分和5分的硬币70枚,小红算了一下,一共有194分,求两种硬币各有多少枚?例3:一次数学竞赛共有20道题。

(人教版)历史必修二:第12课《从计划经济到市场经济》同步练习及答案

第四单元第十二课时间:45分钟满分100分一、选择题(本大题共10小题,每小题4分,共40分)1.(2018·广东学业水平测试)中共十一届三中全会使党和国家的工作重心转移到经济建设方面。

十一届三中全会召开于( )A.1949年B.1956年C.1966年D.1978年解析:本题考查学生再认再现史实的能力。

1978年12月,中国共产党十一届三中全会在北京召开,确定今后党和国家的工作要以经济建设为中心。

答案:D2.下图所体现的内容( )A.推动了中国广大农村人口迅速增长B.使农民获得了土地流转过程中的处分权C.有利于中国农产品的市场化D.改变了中国农村的生产资料所有制性质解析:题干图片反映了“包产到户”的实施,在之后迅速扩展到全国,提高了农村生产力,粮食产量得到极大提高,出现了大量剩余产品,所以有利于农产品的市场化,故C项正确。

中国在20世纪80年代一直坚持计划生育政策,故A项错误;B项发生在21世纪以来,错误;家庭联产承包责任制坚持以社会主义公有制为主体,故农村中生产资料的所有制性质没有变化,D项错误。

答案:C3.(2018·金华十校高一联考)20世纪80年代,我国农村改革的突破性进展推动了城市经济体制改革。

此处“推动”主要体现在农村改革( )A.逐步地废除了人民公社体制B.极大提高了劳动者的积极性C.使农村的经济形势和社会面貌得以改变D.突破了“包产到户”等同于资本主义的观念解析:1980年中共中央发出加强和完善农业生产责任制的文件,首次突破多年来把“包产到户”等同于“分田单干”和资本主义的观念,肯定“包产到户”不会脱离社会主义轨道。

说明农村改革的突破性进展主要体现在“观念”的变化,因此D项符合题意。

答案:D4.(2018·石家庄高一检测)下图是我国某地城乡居民年人均收入表,图中的城乡差距扩大是因为( )A.社会主义市场经济体制的建立B.家庭联产承包责任制的推行C.城市经济体制改革的推行D.经济特区的广泛建立解析:本题考查学生图表解读能力。

就在我被俘的那一天——一个最不幸的日子,有两个国方兵士,在树林中发现了我,而且猜到我是什么人的时候,他们满肚子热望在我身上搜出一千或八百大洋,或者搜出一些金镯金戒指一类的东西,发个意外之财。

哪知道从我上身摸到下身,从袄领捏到袜底,除了一只时表和一支自来水笔之外,一个铜板都没有搜出。

他们于是激怒起来了,猜疑我是把钱藏到哪里,不肯拿出来。

他们之中有一个左手拿着一个木柄榴弹,右手拉出榴弹中的引线,双脚拉开一步,做出要抛掷的姿势,用凶恶的眼光盯住我,威吓地吼道:“赶快将钱拿出来,不然就是一个炸弹,把你炸死去!”“哼!你不要做出那难看的样子来吧!我确实一个铜板都没有存;想从我这里发洋财,是想错了。

”我微笑着,淡淡地说。

“你骗谁!像你当大官的人会没有钱!”拿榴弹的兵士坚不相信。

“决不会没有钱的,一定是藏在哪里,我是老出门的,骗不得我。

”另一个兵士一面说,一面弓着背重来一次将我的衣角裤裆过细的捏,总企望着有新的发现。

是不是还要问问我家里有没有一些财产?请等一下,让我想一想,啊,记起来了,有的有的,但不算多。
