1、图中,直线上依次有A、B、C、D、E、F六个点,且AB=a,BC=b,CD=c,DE=d,EF=e,求图中所有线段长度的和(用a、b、c、d、e求长度)(这图凑合着看看吧)
━A━━━B━━C━━━━━D━━━E━F━
a b c d e
解:图中所有线段及其长度如下:
AB=a
AC=a+b
AD=a+b+c
AE=a+b+c+d
AF=a+b+c+d+e
BC=b
BD=b+c
BE=b+c+d
BF=b+c+d+e
CD=c
CE=c+d
CF=c+d+e
DE=d
DF=d+e
EF=e,
所有线段长度相加得所有线段的和为5a+8b+10c+8d+5e
2、一个长方体的长是8厘米,宽是长的4分之3 ,高是宽的75%.求:这个长方体的表面积.
解:长:8,宽:8x3/4=6,高:6x75%=64.5
S=(8x6+8x4.5+6x4.5)x2=222
3、互为余角的两个角的差为15°,求:
(1)较大角的补角的度数; (2)较小角的补角与较大角的补角的差.
解:设较大角为X度,所以x-(90度-x)=15,x=52.5度
因为较大角是52.5度,所以它的补觉是127.5度
较小角是37.5度,所以它的补角是142.5度
所以差为15度
4、在-5分之3 和5分之2 之间插入三个数,使这五个数中每相邻两个数的差都相等,求插入的这三个数。
解: 设每两个数之间的差为x
则,-3/5 +4x=2/5
解得到x=1/4,
所以这三个数是分别是-7/20 , -1/10 , 3/20
5、用甲、乙、丙三种糖果按2∶4∶3的比,混合成135千克什锦糖,问需要甲、乙、丙三种糖果各多少千克?
解:2+4+3=9
则需要甲:135 x 2/9=30
乙:135 x 4/9=60
丙:135 x 3/9=45
6、今天小丽一家人的岁数总和是100岁,爸爸比妈妈大5岁,妈妈的岁数是小丽岁数的4倍少2岁,则小丽和爸爸,妈妈今年各几岁?
解:设小丽今年x岁,则妈妈为4x-2 岁,爸爸4x-2+5 岁
依题意得
x+4x-2+4x-2+5=100
解得x=11
所以妈妈42岁,爸爸47岁
7、小丽家安装了分时电表,每天早上6:00到晚上22:00为平时段,每度电0.61元,其余时间为谷时段,每度电比平时段便宜0.31元,以知小丽家谷时段的耗电量是平时段的½ ,本月共付电费100.32元,求小丽家本月的耗电量.
解: 设平时段耗电量为x度,则谷时段耗电量为1/2x度
依题意得 0.61x+(0.61-0.31)× 1/2x=100.32
解得 x=132
1/2x=66
66+132=198
所以本月平时段耗电量为132度, 谷时段耗电量为66度,总耗电量为198度。
8、体育场有一环形跑道长400米,甲、乙两人练习长跑,甲每秒跑8米,乙每秒跑7米,两人在相距60米的地方同时同向而行,多少秒后两人第一次相遇?
解:设x秒后相遇
依题意得
7x+60=8x
解得x=60
所以六十秒后两人第一次相遇

1.设BC为x,则AB为4x,AC为5x,DC为2.5x,而DC=2.5,所以x=1
所以AB=4x=4
2.180-∠a=7/3∠a+10 所以∠a=127.5°

4. D__A_B___C
1、4倍

5.由于( a + 8 ) 2 + | b – 7 | = 0,
而( a + 8 ) 2 和| b – 7 |均为非负数,
所以a+8=0,b-7=0 得a=-8,b=7
所以( a + b )2oo2 + ( a + b ) 2oo3=0
6.-1/2+(-1/3)=-5/6
则倒数为-6/5
平方得36/25
乘以5平方,即25 得36
所以答案为36
7.设上班路程是x公里,则
1/10x÷5+(9/10x-1)÷25+1÷5=x÷5-2

所以上班路程是15公里.

x+y=14-3
3x+2y=28-3
解得x=3,y=8
所以投中了3个三分球,8个两分球.
9.设免费的重量为xkg,超过的行李费为y元/kg,则
3x+0.5÷y+1.5÷y+2.5÷y=120
x+9.5÷y=120
解得x=25,y=0.1
则小杰行李重25+0.5÷0.1=30kg,
小明行李重25+1.5÷0.1=40kg,
小丽行李重25+2.5÷0.1=50kg。
10.无解

½ax+5=(7x-3)分之2确定是这样吗?我算了一下还是无解。。。a、x不可能
