1000-527+432=905
验算
58=510-(135+317)
135=510-(317+58)
317=510-(135+58)
527=1000+432-905
432=527+905-1000
1000=427+905-432 - 1年前

请数学高手帮忙看一下这幅图,可以放大. 我想不明白为什么上图的三角形与下图的非三角形面积相等?
如果根据三角形面积计算公式,不是应该是下图的非三角形补充那一块后才会与上图的三角形面积相等么?
另外求助那个著名的旅馆问题:
这道题的题目是这样的:3人一起去旅馆投宿,一个3人间的价格是30元,于是每人交了10元.等钱交完后,老板说给他们优惠5元,让服务员把钱退给3个人,服务员说5元退给3人很难分均匀,就自己拿走了2元,把余下的3元以1元1人的标准还给了那3个人.现在问你:3人实际每人交了9元,一共是27元,加上服务员那里的2元,总数是29元,但原先他们一共掏出了30元,这样还差1元,那么这1元钱到哪里去了?
我知道这是一个偷换概念的问题,也看过各种各样的解答,现在只是想问清楚,到底是哪个概念和哪个概念偷换了呢?
附:答案是说服务员那两元已经在27元里了h____d1年前4

又见故人来 共回答了26个问题
|采纳率92.3%第一个问题,其实很简单.只是你被那图形迷惑了而已,两张拼过后的图并不是一样的,两个拼后的大“三角形”其实并不是真实一样的三角形,斜边不一样,因为斜边不一定就是直线,图形上看上去像是直线,但事实上如果你用勾股定理简单算一下的话,发现根本就不是直线.
第二个问题就更简单了.老板收了30元,让服务员退了5元,所以老板实际上收了25元.
服务员扣了5元中的2元,所以服务员实际上收了2元.
服务员退给三人3元,每人一元,所以实际上三人总共就付了27元.正好就是老板收到的25元加上服务员自己扣的2元之和.关键在于:站在三个房客的角度就要把老板和服务员都看成是外部关系;站在老板的角度就要把服务员和房客都看成是外部关系.不能弄混了.1年前查看全部

|采纳率78.9%问题1,a comparison of British geological publications over the last century and a half对于过去一个半世纪的英国地质学领域的出版物的比较,reveals not simply an increasing emphasis on the primacy of research其揭示了不仅是越来越强调科研的主导地位,but also a changing definition of what constitutes an acceptable research paper.也在于可接受的科研论文组成的定义的改变.问题2,句子的主语其实是a comparson(单数),所以 reveal加了s,如果说是指一半的出版物(a half of the publications)里面就不止2个了,是复数,那么reveal 就不需要加s.所以这里的half 是与前者相连,是指 the last century and a half,过去一个半世纪.希望我这样的解释对你有所帮助.晚安.1年前查看全部

我写寒假日记,把所有的都复制了下来,然后改了改,这算不算抄袭你们给看一下。 原文
改后:一天,南因先生家里来了一位客人,要向南因先生请教学问。南因先生接待了他。可等客人坐下之后,客人并没有听南因先生讲话,而是自己滔滔不绝地讲了起来。从自己的生活、工作,及至家庭等等,一口气说了大半天,南因先生几次想插话都未成功。
南因先生静静地听着,过了一会儿,他站起身来,走进厨房,端来了茶。往客人的杯子里倒茶,虽然倒满了但是仍在继续倒,仿佛根本就没有看见一样。
一旁的客人一开始觉得十分奇怪,看到南因先生还没停下,水已经开始往外溢了,他终于忍住了手。
“你没看见杯子已经满了吗?”客人说。
“再也倒不进去啦!” 客人又说
“这倒是真的,”南因先生终于住了手,“和这个杯子一样,你自己已经装满了自己的想法。要是你不给我一只空杯子,我怎么给你讲呢?”
从这个故事当中,我知道了:要使自己的思想吐故纳新,就要及时将大脑清空,如同必须清空装满了水的杯子才能容纳更多的东西一样。wangdalou1年前1

简单英语句子,帮我看一下!
This battlefield is consecrated to the memory of the soldiers who died here.
这句话从结构上说应该是完整的吧,翻译出来怎么说?
是不是应该在 to 后加个 cherish 或是 honour 更好?还是我这样画蛇添足了?

- JIP76,麻烦你帮我看一下,问:用2.5P 20K1.5(2.5MHz,Φ20mm,tgβ=1.5)斜探头,检验T=1
JIP76,麻烦你帮我看一下,
问:用2.5P 20K1.5(2.5MHz,Φ20mm,tgβ=1.5)斜探头,检验T=100mm钢板对接焊缝,扫描按深度1:1调节,探伤灵敏度为 φ3x40-14dB,探伤中发现一缺陷,深40mm,波高25dB,按GB11345-89标准B级,此缺陷如何评定?(楔中等效横波声程取为 10mm).
设x1,x2分别为孔深d1=100mm,d2=40mm时的声程:已知K=1.5,L=10mm
x1=d1(K2+1)1/2+L=100x1.8+10=190(mm),x2=d2(K2+1)1/2+L=40x1.8+10=82(mm)
两孔反射波高dB差△=30lg(x1/x2)=30lg(190/82)=11dB,∴ d2=40mm,
φ3x40孔的波高为:[H2]=[H1]+△=14+11=25dB,判废线灵敏度为φ3-2dB,即23dB,缺陷波高25dB,表明缺陷波高已位于距离波幅曲线的III区,按GB11345-89标准的规定,应评定为IV级.
1.两孔反射波高dB差△=30lg(x1/x2)=30lg(190/82)=11dB 我认为公式应该是△=40lg(x1/x2)
2.d2=40mm时,φ3x40孔的波高为:[H2]=[H1]+△=14+11=25dB,这是用的什么公式导来的呢,
谢谢你JIP76,盼复.
我看到JIP76你的回复了,还是有点不明白,
1.两孔波高又差 11dB,那这两孔是哪两孔啊?(我理解是钢板100时的孔,和发现缺陷时40的孔,),
2.φ3x40 比 φ3x40-14dB要高 14dB;两孔波高又差 11dB.这两个14DB和11DB,单个我都明白了,但与求曲线基准线φ3x40的DB,有什么关系呢,为什么就得14+11=25dB
另外,那个论坛,我怎么总上不去呢,换了几个机器在也不好使.QIAO11MEI1年前1

|采纳率93.8%1.“探伤灵敏度为 φ3x40-14dB”——说明是长横孔,既然是长横孔就是30倍的lg关系;当然为30lg(x1/x2)
2.“φ3x40孔的波高为:[H2]=[H1]+△=14+11=25dB”——用不着公式啊,其实就是告诉你这25dB是怎么来的.首先 φ3x40 比 φ3x40-14dB要高 14dB;两孔波高又差 11dB.所以就有14+11=25dB
————————————————————————————————
我今天发现他给的条件是不对的GB11345-89标准B级的话判废线灵敏度为φ3-4dB 才对!
如果是我我会这样
1.算出两孔差(11dB)
2.那么次缺陷应为φ3-3dB
3.又因B级时判废线灵敏度为φ3-4dB
4.得出缺陷波比判废线灵敏度高出1dB ,应评定为IV1年前查看全部

|采纳率88.2%42左右.描写梦中的景色不是很明显能够表现“生活也是一堂语文课”的观点.需要在生活中感悟,而你在梦中感悟有点不恰当.但是如若你醒来后激起斗志那一段,详细地能够描写出内心的变化和坚定,从害怕变成充满斗志的,并且再融入一点与“生活”有关的事情,那也是一篇很好的文章.你这样具体也不好打分.1年前查看全部

解析:
(1)从表中可看出,将书分成 2、4、8、16、…、2n份时,拉力F将分别增加6 N、12 N、24 N、…、3×2n N,故将书分成32份时,增加的拉力应为 48 N,故力 F=46.5 N+48 N=94.5 N.
(2)逐页交叉时,需拉力F=190.5 N,恰好是把书分成 64份时,增加的拉力为2×48 N=96 N,需拉力 F=94.5 N+96 N=190.5 N.可见,逐页交叉刚好分为64份,即该书有64张.
