本年度最后一次求外语平台完形填空答案

报告.因为这些事情当事单位已经决定了,并且确认.这个我文件只是一个汇报的形式.而请示是表示需上级领导决定的事.

解题思路：（1）根据若每辆车投入成本增加的比例为x（0＜x＜1），则出厂价相应的提高比例为0.75x，同时预计年销售量增加的比例为0.6x和年利润=（出厂价-投入成本）×年销售量．建立利润模型，要注意定义域．
（2）要保证本年度的利润比上年度有所增加，只需今年的利润减去的利润大于零即可，解不等式可求得结果，要注意比例的范围．

（1）由题意得
y=[1.2×（1+0.75x）-1×（1+x）]×1000×（1+0.6x）（0＜x＜1）（4分）
整理得y=-60x²+20x+200（0＜x＜1）．（6分）
（2）要保证本年度的利润比上年度有所增加，当且仅当

y−(1.2−1)×1000＞0
0＜x＜1.
即

−60x2+20x＞0
0＜x＜1.（9分）
解不等式得0＜x＜
1
3．
答：为保证本年度的年利润比上年度有所增加，投入成本增加的比例x应满足 0＜x＜0.33．（12分）

目标利润=预计销量×（单价-单位变动成本）-固定成本
设:计划年度应销售X件甲产品
X*(200-120)-135000=320000
求:X=5687.5
即:计划年度应销售5688件甲产品才能实现目标利润320000

这是一元三次、不是三元一次
解是个无理数,X1≈1.189,X2≈-4.59+2.4i,X3≈-4.59-2.4i

本年度,首先一炮打响——拼!
拼在成绩.做为一个学生,最切实际的一个名词——成绩.无论谁,总爱把孩子的成绩放在第一位,在长辈的眼里,成绩就代表了一切.每天面对如山的作业,偶尔的小小放松,却被说成了“松懈”,只是因为那不怎么优秀的成绩.也只有提高成绩,才能得以放松吧.
拼在排名.如果虚假一点,那么我能一步登天.可是,我是人而不是神,所以,我只能一歩一个脚印,打下扎实的基础,让自己的名字在排行榜上一个个上升.因为,在我的老师眼里——排名就能说明一切.
拼在梦想.梦想就像一双翅膀.可以让我起飞.一个美丽的梦想,可以带着自己飞向成功的天堂.可是一个糟糕的梦想,足以让人从天堂坠入到人间.那种感觉,一定能令人抓狂.
当“拼”告一段落后,那就让我张开双手迎接“笑”吧!
“笑”的基础是建立在“拼”之上的,有拼才有笑,会拼才会笑,“笑”与“拼”就是一对孪生姐妹,她们总是形影不离.
当然,笑是令人愉快的,这一点,与“拼”就开始无关了.
开怀大笑.笑,有益身心健康开怀大笑,有益于释放心中压力.开怀大笑总归是不太文雅的,所以我会尽量找个没人的地方开怀大笑.要不然,别人可会把我当疯子的呢.
微笑.对自己微笑,对他人微笑.微笑是语言外的另一种表达方式,有助于沟通交流,是极其重要的.
“拼”和“笑”,本年度,我将朝这两个字冲刺、拼搏!

1,设y=k/(x-0.4)
当x=0.65时,y=0.8
即k/(0.65-0.4)=0.8
k=0.2
∴y=0.2/(x-0.4)
2.上一年用电量为一亿度
上一年的收益为：(0.8-0.3)×1=0.5（亿元）
本年度的收益为：(x-0.3)(1+y)=(x-0.3)[1+0.2/(x-0.4)]
(x-0.3)[1+0.2/(x-0.4)]=0.5×(1+20%)
(x-0.3)[(x-0.4)+0.2]=0.6(x-0.4)
(x-0.3)(x-0.4)+0.2(x-0.3)=0.6(x-0.4)
x²-0.7x+0.12+0.2x-0.06=0.6x-0.24
x²-1.1x+0.3=0
(x-0.5)(x-0.6)=0
x=0.5 或 x=0.6
答：当电价调整至0.5元或0.6元时,本年度的电力部分的收益比上一年增加20% .

（1）这些文章的主题都是表现人间真情的.（从上述文章的题目中找出这些题目的共同点,虽有友情、父爱、母爱等不同角度,但都属于人间真情）
（2）①撰写文章要贴近生活,抒发真情.②发现并揭示平凡生活（或人性）的闪光点,表达人们对真、善、美的追求（或对美好人生的追求）.（杂志是大众读物,内容应贴近生活,表现真情；杂志又是一个宣传阵地,必须弘扬真善美等.这就决定了刊登文章的内容）

2006年的存货资金占用量=（5300000-300000）*（1+30%）*（1-15%）=5525000
希望可以帮到你

（1）由题意可知,本年度每辆车的利润为10（1+0.75x）-8（1+x）
本年度的销售量是12（1+0.5x）,
故年利润y=12（1+0.5x）[10（1+0.75x）-8（1+x）]
=-3x2+6x+24,x∈(0,1/2]
（2）设本年度比上年度利润增加为f（x）,
则f（x）=（-3x2+6x+24）-24=-3（x-1）2+3,
因为x∈∈(0,1/2]
在区间∈(0,1/2]f（x）为增函数,
所以当x=1/2时
函数y=f（x）有最大值为
9/4故当x=1/2时
本年度比上年度利润增加最多,
最多为2.25亿元
无问题请采纳

解题思路：如果女生也是增 4%，这样增加的人数是290×4%=11.6（人），比 13人少1.4人，少的1.4人就是因为女生本是增加5%，而算成4%，少算了上年度女生的1%，用除法可求出上年度女生的人数，根据“上年度男、女生共290人”算出上年度男生的人数，又因为4%，5%的单位“1”是上年度女生和男生，所以用乘法可算出本年度男女生人数．

如果女生也是增加 4%，这样增加的人数是：
290×4%=11.6（人），
女生少算了：
13-11.6=1.4（人），
上年度女生是：
1.4÷（5%-4%）=140（人），
上年度男生有：
290-140=150（人），
本年度男生有：
150×（1+4%）=156（人），
本年度女生有：
140×（1+5%）=147（人），
答：本年度该校有男生156人，女生147人．

点评：
本题考点： 列方程解含有两个未知数的应用题；百分数的实际应用．

考点点评： 解此题的关键是先算出上年度男女生的人数，再根据增加的比算出本年度的男女生人数．

根据公式
从今年9月9日到明年9月5日收滞纳金,一共是362天,合计RMB76.65元

本年度每辆车的投入成本为10×（1+x）；
出厂价为13×（1+0.7x）；年销售量为5000×（1+0.4x）,
因此本年度的利润为
y=[13×（1+0.7x）-10×（1+x）]×5000×（1+0.4x）
=（3-0.9x）×5000×（1+0.4x）
=-1800x2+1500x+15000（0＜x＜1）,
由-1800x2+1500x+15000＞15000得

汽车的发展史
Development of the Automobile
The automobile has a long history.The French engineer Nicolas Joseph Cugnot built the first self-propelled vehicle (Paris,1789),a heavy,three-wheeled,steam-driven carriage with a boiler that projected in front; its speed was c.3 mph (5 kph).In 1801 the British engineer Richard Trevithick also built a three-wheeled,steam-driven car; the engine drove the rear wheels.Development of the automobile was retarded for decades by over-regulation:speed was limited to 4 mph (6.4 kph) and until 1896 a person was required to walk in front of a self-propelled vehicle,carrying a red flag by day and a red lantern by night.The Stanley brothers of Massachusetts,the most well-known American manufacturers of steam-driven autos,produced their Stanley Steamers from 1897 until after World War I.
The development of the automobile was accelerated by the introduction of the internal-combustion engine.Probably the first vehicle of this type was the three-wheeled car built in 1885 by the engineer Karl Benz in Germany.Another German engineer,Gottlieb Daimler,built an improved internal-combustion engine c.1885.The Panhard car,introduced in France by the Daimler company in 1894,had many features of the modern car.In the United States,internal-combustion cars of the horseless buggy type were manufactured in the 1890s by Charles Duryea and J.Frank Duryea,Elwood Haynes,Henry Ford,Ransom E.Olds,and Alexander Winton.Many of the early engines had only one cylinder,with a chain-and-sprocket drive on wooden carriage wheels.The cars generally were open,accommodated two passengers,and were steered by a lever.
The free growth of the automobile industry in the early 20th cent.was threatened by the American inventor George Selden's patent,issued in 1895.Several early manufacturers licensed by Selden formed an association in 1903 and took over the patent in 1907.Henry Ford,the leader of a group of independent manufacturers who refused to acknowledge the patent,was engaged in litigation with Selden and the association from 1903 until 1911,when the U.S.Circuit Court of Appeals ruled that the patent,although valid,covered only the two-cycle engine; most cars,including Ford's,used a four-cycle engine.The mass production of automobiles that followed,and the later creation of highways linking cities to suburbs and region to region,transformed American landscape and society.

Good after, ladies and gentlemen,
Welcome to this year’s English speech competition. I’m the leader of student union. My name is Li Hua. Our school holds the English speech competition every year. So you should understand the rule very much. The theme is “The English Novel I like Best” this time. Please join in this activity. It is a profitable activity. It can increase your ability of listening English and speaking English. And it can help you to cultivate a reading book habit. In addition, anyone can’t give lecture over five minutes and everyone must speak fluent, pronounce accurate. At last, I hope that the English speech competition can success. More students can increase their ability during the activity.

税前利润总额＝息税前利润总额-债务筹资成本总额＝90万元-40万元＝50万元
单位产品销售收入＝单位变动成本÷变动成本率＝100÷40%＝250元
经营杠杆系数＝边际贡献总额÷税前利润总额＝（10000×250）×（1-40%）÷50万＝3
财务杠杆系数＝息税前利润总额÷税前利润总额＝90万÷50万＝1.8
总杠杆系数＝经营杠杆系数×财务杠杆系数＝3×1.8＝5.4

在权责发生制下本月费用为办公开支800元,答案为C
支付下年第一季度房屋租金3千元计入预付账款,不属于本月支出

由题意得变动成本率=（66万-30万）/60万=60%
增加广告费用后固定成本增加为30万+4万=34万
（1）保本销售额即使边际贡献额=固定成本
所以设销售额为X
X*（1-60%）=34万
X=85万
保本额为85万
（2）为达到利润5万
设销售额为X
X*（1-60%）-34万=5万
X=97.5万
（3）安全边际=正常销售收入-盈亏临界点销售收入=97.5万-85万=12.5万
安全过际率=12.5万/97.5万=12.82%
(4)
单价5元时保本量=85/5=17万件
单价5元时实现5万利润销售量=97.5/5=19.5万件

I'd like to recommend WuChun for this year's youth award
Most of the time he slept on my knee
Don't be afraid of the dog, he never bite
We must keep quiet in the library
The cat not provoke any trouble
When someone rang the doorbell, the dog will tomas call
Don't put the children to stay at home alone
Exercise every day at least two is a good idea

本年度,首先一炮打响——拼! 拼在成绩.做为一个学生,最切实际的一个名词——成绩.无论谁,总爱把孩子的成绩放在第一位,在长辈的眼里,成绩就代表了一切.每天面对如山的作业,偶尔的小小放松,却被说成了“松懈”,只是因为那不怎么优秀的成绩.也只有提高成绩,才能得以放松吧. 拼在排名.如果虚假一点,那么我能一步登天.可是,我是人而不是神,所以,我只能一歩一个脚印,打下扎实的基础,让自己的名字在排行榜上一个个上升.因为,在我的老师眼里——排名就能说明一切. 拼在梦想.梦想就像一双翅膀.可以让我起飞.一个美丽的梦想,可以带着自己飞向成功的天堂.可是一个糟糕的梦想,足以让人从天堂坠入到人间.那种感觉,一定能令人抓狂. 当“拼”告一段落后,那就让我张开双手迎接“笑”吧! “笑”的基础是建立在“拼”之上的,有拼才有笑,会拼才会笑,“笑”与“拼”就是一对孪生姐妹,她们总是形影不离. 当然,笑是令人愉快的,这一点,与“拼”就开始无关了. 开怀大笑.笑,有益身心健康开怀大笑,有益于释放心中压力.开怀大笑总归是不太文雅的,所以我会尽量找个没人的地方开怀大笑.要不然,别人可会把我当疯子的呢. 微笑.对自己微笑,对他人微笑.微笑是语言外的另一种表达方式,有助于沟通交流,是极其重要的. “拼”和“笑”,本年度,我将朝这两个字冲刺、拼搏!

I would like to tell you about my favorit classmate Wang Fang, who I believe should receive the Best Student Award of the year.
Wang Fang is an excellent student. She got good grades in all the courses. She is smart and thoughtful. She is also friendly and considerate, always thinking of others first. Last month when she was on her way home, she rescued a little girl from the river, and took care of her until her parents arrived.
对不起,60个字无法把所有的提示包括了.你可以自己删改.
希望对你有帮助.

y=k/(x-0.4)
x=0.65,y=0.8
0.8=k/0.25
k=0.2
y=0.2/(x-0.4)=1/(5x-2) x>0
题目是这样的吧
某市上一年度电价为每度0.8元,年用电量为1亿度.本年计划将电价调至每度0.55元至0.75元之间.经测算,若电价调至x元,则本年度新增用电量y(亿度)与(x-0.4)(元)成反比例,又当x=0.65时,y=0.8
(1)求y关于x的函数解析式.
(2)请估计本年度计划用电量的范围.(精确到0.01)
是的话
2）
x∈[0.55,0.75]
x=0.55,y有最大值,
y=0.2/(0.15)=1.33
x=0.75有最小值
y=0.2/(0.35)=0.57
所以今年预计是最少是0.57+1=1.57
最多1.33+1=2.33
用电范围是[1.57,2.33]
