2.西尔维娅有14枚硬币,其中全部是5分硬币和两角五分的硬币.如果她花费了2.9元,那么她用去了多少五分和两角五分的硬币.写出你的计算过程.
1.证明:
∵△ABC=△EDF,∴∠ABC=∠EDF.
在△DGB中,∠ABC=∠EDF,则DG=BG
∴△DGB是等腰三角形.
2.设五分硬币的数量为x,那么两角五分硬币的数量为14-x,根据题意得
0.05x+0.25(14-x)=2.90
解得 x=3
14-x=14-3=11
答:五分硬币和两角五分硬币 的数量分别是3枚和11枚.

  在拿到题目的时候就应该在脑海中形成这样一个图像:一个等边三角形内接在一个圆里面.那么所有的数值都可以算出来,先不要看题目,我们心算出圆的半径和等边三角形的一个边的关系:1:√3,其他关系,比如三角形和圆面积的关系也可以都算出来,这时候再来看题目的两个题肢:三角形一个边的边长,和圆的直径(注意是直径不是半径),他们的比值就是√3:2,也就是1.732:2 (这些基本的数值要知道)那么很显然就是选B.

一个三角形的周长是2005cm. 最长边比中等长边长330cm,中等长边比最短边长332cm. 它的边长分别是多少?
中=短+332 1
中=长-330 2
2005=长+中+短 3
1+2, 有:
2中=短+长+2
代入 3,有:
2005=2中+中-2
中=669
于是:
短=669-332=337
长=669+330=999

这个知道回答是教你求对一个轴的惯性矩.
极惯性矩就是两个方向相加bh3/18
回转半径就是 极惯性矩除以面积的平方根
所以就是 √(bh3/18/(bh/2))=√(h2/9)
所以回转半径为h/3,h=√3*a
所以回转半径为 √3*a/3

Every time I think of you
I feel shot right through with a bow of gloom
It's no problem of mine
But it's a problem I find
Living a life that I can't leave behind
There's no sense in telling me
The wisdom of a fool won't set you free
But that's the way that it goes
And it's what nobody knows
While every day my confusion grows
Every time I see you falling
I get down on my knees and pray
I'm waiting for that final moment
You'll say the words that I can't say
I feel fine and I feel good
I'm feeling like I never should
Whenever I get this way
I just don't know what to say
Why can't we be ourselves like we were yesterday
I'm not sure what this could mean
I don't think you're what you seem
I do admit to myself
That if I hurt someone else
Then I'll never see just what we're meant to be

奇异三角恋
每次我想起你
都仿如被阴郁之弓射中
这本不算我的问题
是我自寻苦恼
生活在无法割舍的过去里
说教是徒劳的
蠢人的智慧无法让我释怀
但事实就是如此
没人知道
日复一日我越发迷惘
每次我看到你倒下
我双膝跪地虔诚祈祷
我在等待那最后的时刻
你说出我无法言表的词句
我感觉很好
一种前所未有的感觉
每次置身此情此景
都无言以对
为什么我们不能回到昨天
不清楚那意味着什么
你似乎在掩饰着什么
我向自己坦白
如果伤害别人
那就永远看不到我们俩注定的未来

第一题:可以用正弦定理得:sinA /a=sinB /b
所以得sinA=1/2,所以angle A=30度
第二题:由韦达定理得:方程根=[(-2i±根号下(4i²+16)]/2=-i±根号下3
所以选e
希望答案能满意.

再来条英文数学题
IN TRIANGLE ABE,THE NEASURE OF ANGLE B IS THREE TIMES THE MEASURE OF ANGLE A.THE MEASURE OF ANGLE C IS 30度 GREATER THAN THE MEASURE OF ANGLE A.FIND THE ANGLE MEASURE.
三角形ABE.角B是3乘角A.THE MEASURE OF ANGLE C系30度,大于角A`角A是什么?
不知道这样翻译对不对``翻译有错`就帮我纠正下`谁会做这题?
列出来`要过程,结果

首先,你有拼写错误,neasure应该是measure.从题意看,三角形应该是abc,而不是abe.
角B是角A的3倍,角C比角A大30度.
角B=3*角A,角C=角A+30度
角A+角B+角C=180,
得出角A=30度.
因此角B=90度,角C=60度.
In a triangle,if measures of three&
In a triangle,if measures of three angles are x,2x and 3x respectively,then the measure of the largest angle is(  )
(英汉词典triangle:三角形,Measure:量度,the largest angle:最大角.)
A.150° B.120° C.90° D.60°

∵三角形的内角和为180°,
∴x+2x+3x=180°,
解得x=30°,
所以3x=90°.
故选C.
关于location的!the circle is to the left of the triangle我能不能说 t
关于location的!
the circle is to the left of the triangle
我能不能说 the circle is left to the triangle
俩句话一样吗?有没有语法错误?

left 表示“左边”是有固定用法的,简单来说 on the left,to the left
你想到的 is left 实际上是这样用的 Tom was left alone :tom 一个人被留下来了
left是leave的变形,be left 大多这样用
但是 原则上来讲你的用法没有语法错误
