我很早就在按照这个方案来分析一切东西,我想问一下,时间是否属于逻辑?

显然B车先到交点.那么,一定是B车过了交点后,两车距离最近.(因为A车离交点更近了)
那么,可以列出方程:
（1000-y)/(100/9)=(500+x)/(25/3)
化简可得：
3y+4x=1000
所以,y=(1000-4x)/3
A 与 B 的距离根据勾股定理可得,为
√x2 +y2（x的平方加y的平方,再开二次方根）
将y=(1000-4x)/3代入,化简可得
原式=√[（5x-800)+360000]2（平方）/9
所以,当x=160时,原式最小,最小值为200
这时B车行驶了160+500=660（m）
所以,时间t=660/（25/3）=79.2s

2520是1至9这九个自然数的倍数
2520÷1=2520
2520÷2=1260
2520÷3=840
2520÷4=630
2520÷5=504
2520÷6=420
2520÷7=360
2520÷8=315
2520÷9=280

帮楼上的修正一下,要么说in order to celebrate her birthday,要么直接说for the birthday party,而不会说庆祝聚会.

现时世界普遍采用的公历是格列高里历,它的前身是儒略历.根据儒略历的规定,每4年有1个闰年,闰年为366日,其余3年(称为平年)各有365日.公元年数能被4除得尽的是闰年.儒略历1年平均长365.25日,比实际公转周期的365.2422日长11分14秒,即每400年约长3日. 教皇格列高里十三世于1582年宣布改历,改变置闰规则.公元年数被4除尽的是闰年,但如被100除得尽而被400除不尽的则不是闰年.这样的做法可在400年中减少3个闰年.在格列高里历下,400年中有97个闰年(每年366日)及303个平年(每年365日),所以每年平均长365.2425日,与公转周期的365.2422日十分接近.

转瞬间严冬已逝,春天已悄悄地来到人间.春天,是美好的季节,是充满诗情的季节；春天,又意味着一个生机勃勃的开始.自古以来,诗人喜爱春天,赞美春天,是因为春天景色宜人,处处皆可入诗.漫步古诗百花园,只见咏春诗姹紫嫣红...

My father often comes back home quite late after work.But yesterday he came home very early despite the traffic jam.He cooked dinner because it was mum's birthday yesterday.

因为总共有8只面包,每个人吃了8/3只
过路人吃的8/3只面包值8个银币
所以1只面包值：8÷(8/3)=3银币
其中哈桑给了那个过路人3-(8/3)=1/3只
他应该得到：3×(1/3)=1个银币
萨里曼给了那个过路人5-(8/3)=7/3只
他应该得到：3×(7/3)=7个银币

He gets up early every day.

The old man goes to bed early,but late in falling asleep.

一元三次方程的解其中有一种情况是含复数的.再说,完全立方公式比解一元三次方程容易多啦.

I get up early on weekends.

I will be working very early tomorrow morning.

.解: （1）ρ盐水=m/V=60g/50cm^3=1.2g/cm^3=1.2×10^3kg/m3>1.1×10^3kg/m3
所以,不符合要求,应该加水
（2）设应该加水的体积为V水,则ρ盐水V盐水+ρ水V水=ρ(V盐水+V水)
即：1.2×10^3×50×10^-3+1.0×10^3×V水=1.1×10^3[50×10^-3+V水]
可解得：V水=0.05m^3=50L
则将这些盐水配制到符合要求时共为V=V盐水+V水=50L+50L=100L

She gets up very early every day.

呵呵,每个人都经历过这样的事,我上小学的时候天天早上到学校抄别人的作业,初中的时候,自己写作业,但是写的不怎么好,高中的时候别人天天拿着我的作业抄.
凡事贵在坚持,从点点滴滴做起,相信自己能做好,坚持下去就一定能做好!

加油!

是的,就是以前发出的光.
举例说一下,天狼星,距离我们8.6光年.
就是说从天狼星发出的光需要经过8.6年才能到达地球.所以我们看到的是8.6年前发出的光,.
要是你想看到天狼星4年前发出的光,是看不到,你试想一下,4年前天狼星发出的光还在半路上呢,还没到地球.
在说一下,8.6光年就是光8.6年所走的距离.

我来自偶然像一颗尘土
有谁看出我的脆弱
我来自何方我情归何处
谁在下一刻呼唤我
天地虽宽这条路却难走
我看遍这人间坎坷辛苦
我还有多少爱我还有多少泪
要苍天知道我不认输
感恩的心感谢有你
伴我一生让我有勇气作我自己
感恩的心感谢命运
花开花落我一样会珍惜
我来自偶然像一颗尘土
有谁看出我的脆弱
我来自何方我情归何处
谁在下一刻呼唤我
天地虽宽这条路却难走
我看遍这人间坎坷辛苦
我还有多少爱我还有多少泪
要苍天知道我不认输
感恩的心感谢有你
伴我一生让我有勇气作我自己
感恩的心感谢命运
花开花落我一样会珍惜
感恩的心感谢有你
伴我一生让我有勇气作我自己
感恩的心感谢命运
花开花落我一样会珍惜
英文歌词
I come from being like a dust by chance
Have who see my flimsiness of
I come from what square my feeling return where
Who at under a moment calls me
World although this road of breadth but difficult walk
I see the frustrated pain of this human life
How much I still have to love me to still have how much tears
Want the heaven knows my gameness
Heart of feel grateful the with gratitude has you
Companion I make me courageous to make myself from cradle to the grave
The heart of feel grateful thank destiny
The flower blooms to fall me similar will cherish
I come from being like a dust by chance

Want the heaven knows my gameness
Heart of feel grateful the with gratitude has you
Companion I make me courageous to make myself from cradle to the grave
The heart of feel grateful thank destiny
The flower blooms to fall me similar will cherish
Heart of feel grateful the with gratitude has you

解题思路：充分运用提示的信息，分析出反应物生成物和反应条件，从而写出正确的化学方程式．

由提示知：孔雀石加热时分解，生成氧化铜、二氧化碳和水，故方程式为：Cu₂（OH）₂CO₃

△
.
2CuO+H₂O+CO₂↑；加热时，用木炭作还原剂把氧化铜中的铜还原出来，根据反应物的组成，还应生成二氧化碳，但条件应是加热，故方程式为：C+2CuO

高温
.
2Cu+CO₂↑．
故选Cu₂（OH）₂CO₃

△
.
2CuO+H₂O+CO₂↑；C+2CuO

高温
.
2Cu+CO₂↑．

点评：
本题考点： 探究金属铜的冶炼原理；金属的化学性质；碳的化学性质；书写化学方程式、文字表达式、电离方程式．

考点点评： 解题时要充分利用信息，不能对不熟悉的反应无所适从，同时掌握基础知识，提高知识的衍生能力．

那是金星和木星
亮的是金星,暗的是木星.金星距离近,而且大气反光能力强,因此显得特别亮.金星最亮时可以达到-4.4等.木星体积大,反光能力也强,而且两个月前木星刚刚过了冲日阶段.（是指某行星运行到和太阳完全相反的方位上,此时该行星达到最亮.）木星最亮时也在-2等以上.现在木星运行到了西边 而金星由于前一阵刚刚东大距 也在西边
