1.× 2.√ 3.√ 二． 1.B 2.B 3.B 4.D 5.A 三． 1.∠BCE＝∠ABC 2.南偏西55° 3.对顶角相等 等量代换 平角 等量代换 平角 等量代换 补角 4.25 四. 1. ∵∠2＋∠3=180° ∴a‖b（同旁内角互补,两直线平行） ∵∠3=∠4 ∴c‖d（同位角相等,两直线平行） ∵a‖b ∴∠3=∠1＝60°（两直线平行,同位角相等） ∵∠3＋∠5=180° ∠3=60° ∴∠5＝120° 2.跳过 3.证明如下： ∵AB⊥BC ∴∠ABC=90° ∵BC⊥CD ∴∠BCD=90° ∵∠ABC=90°∠BCD=90° ∵∠BCD=∠ABC ∠1=∠2 ∠2＋∠FBC=∠ABC ∠1＋∠BCE=∠BCD ∴∠FBC=∠BCE ∵∠FBC=∠BCE ∴BF‖CE（内错角相等,两直线平行） 4. AB‖CD 理由如下： ∵BE平分∠ABD ∴∠ABD＝2∠1 ∵DE平分∠BDC ∴∠BDC＝2∠2 ∵∠1＋∠2=90° ∴∠ABD＋∠BDC=180° 1. 垂直于同一条直线的直线是平行的 2. 作垂线 要是两条垂线的长度相等那么就是平行的 3. 利用平行线的内错角相等：两个镜子平行,所以90-∠2=90-∠3所以∠2=∠3,则∠1+∠2=∠3+∠4,即进入光线和离开光线的内错角相等,所以平行 一. 1.√ 2.× 3.√ 4.× 二.1.A 2.D 3.A 4.B 5.B 6.D 7..B 8.D 9.B 三. 1.3 6 2.第二 3.-1 4.10 5.甲追乙的时间是11.25小时. 需要4.5小时相遇 甲追乙需要12小时 6. 方程组32（x+y)=400 180(x-y)=400 7.10 8. 因为两个的值不一样,所以有一个数为负数 当x为负数时,x+y=4 |x|+|y|=-x+y=7 解得x=-1.5 y=5.5 x-y=-7 当y为负数时,x+y=4 |x|+|y|=x-y=7 x=5.5 y=-1.5 x-y=7 四. 1.略 2.略 3. 若该矩形ABCD中,是AB=6,AD=4.那么在AB上取一点E使AE=2；在AD上取一点F使AF=1.过点E、点F分别作AD、AB的平行线EM、FN,交于点O,即O为原点,EM为x轴,FN为y轴,则D点坐标为(-2,-3）. 另外三点的坐标为A(-2,1）、B（4,1）、C（4,-3）. 4.将x=2 ,y=1分别代入两个式子里,有 2a+b=3,2b+a=7 解这个二元一次方程得出,b=11/7,a=5/7 5.4x+3y=7(1) kx+(k-1)y=3(2) x=y(3) 因为x=y代入（1） 7x=7y=7 所以x=y=1 代入（2） k+k-1=3 2k=4 k=2 6. x=3,y=4待入a1x+b1y=c1,a2x+b2y=c2,有 3a1+4b1=c1 3a2+4b2=c2 (1) 3a1x+2b1y=5c1 3a2x+2b2y=5c2 方程组两边除5有： 3/5a1x+2/5b1y=c1 3/5a2x+2/5b2y=c2 (2) 比较方程组（1）和（2） 有3x/5＝3 2y/5＝4 所以x＝5,y＝10 7. 设火车的速度和长度分别是v, s 800+s/v=45 800-s/v=35 解得v=20 s=100 1. 解:1.设计划新建校舍X平方米,则拆除校舍为7200-X平方米. 根据题意列出方程: 80%X+(1+10%)(7200-X)=7200 8X+11(7200-X)=72000 3X=79200-72000 X=2400 计划拆除校舍:7200-X=7200-2400=4800(平方米) 答:计划新建校舍和拆除校舍各为2400平方米和4800平方米. 2. 计划新建校舍用的资金:700*2400=1680000(元) 计划拆除校舍用的资金:80*4800=384000(元) 计划在新建和拆除校舍中用的资金共:1680000+384000=2064000(元) 实际新建校舍用的资金:80%*2400*700=1344000(元) 实际拆除校舍用的资金:(1+10%)*4800*80=42240(元) 实际新建和拆除校舍用的资金共:1344000+4240=1386240(元) 节省的资金为:2064000-1386240=677760(元) 节省的资金用来绿化的面积:677760/200=3388.8(平方米) 答:在实际完成的拆建工程中,节余的资金用来绿化是3388.8平方米. 2. 设活动前Ⅰ型冰箱为x台,则Ⅱ型冰箱为960-x台 x(1+30%)+(960-x)(1+25%)=1228 解得x=560 Ⅰ型冰箱:560台 Ⅱ型冰箱：400台 （2）Ⅰ型冰箱:560*（1+30%）=728台 Ⅱ型冰箱：1228-728=500台 13%（728*2298+500*1999） ≈3.5*10五次方 3. 设要用8m的水管X根,5m的水管Y根 8X+5Y=132 因为132-8X是5的倍数,所以8X的尾数是2或7（尾数为7是单数,不会是8的倍数,不考虑尾数7） 所以X的尾数为4或9,且X≤132/8=16.5 所以X可选4；9；14三种,相对Y分别为20；12；4 即有3种方案： 8m的4根 5m的2 8m的9根 5m的12根 8m的14根 5m的4根 因8m的单价50/8元/M＜5m的单价35/7元/m 所以选8m管用得最多的方案最省钱,即选 8m的14根 5m的4根 1. 解 梨每个价：11÷9＝12/9（文） 果每个价：4÷7＝4/7（文） 果的个数： （12/9×1000－999）÷（12/9－4/7）＝343（个）梨的个数：1000－343＝657（个）梨的总价： 12/9×657＝803（文） 果的总价： 4/7×343＝196（文） 设梨是X,果是Y x+y=1000 11/9X+4/7Y=999 解得：X=657；Y=343 即梨是657个,钱是：657*11/9=803 果是343个,钱是：343*4/7=196 2.设树上有x只,树下有y只,则由已知的,得： y-1/x+y=1/3 x-1/y+1=1 解得x=7;y=5 即树上有7只,树下有5只. 1. C 2. C 3. 120° 4. ∠AMG=∠3． 理由：∵∠1=∠2, ∴AB‖CD（内错角相等,两直线平行）． ∵∠3=∠4, ∴CD‖EF（内错角相等,两直线平行）． ∴AB‖EF（平行于同一条直线的两直线平行）． ∴∠AMG=∠5（两直线平行,同位角相等）． 又∠5=∠3, ∴∠AMG=∠3． 5. .(1)设随身听为x元,书包为y元, x+y=452 x=4y-8 将2代入1得 4y-8+y=452,解之得y=92,x=360 （2）若在A买的话要花费452*0.8=361.6（元） 若在B买要花费360+（92-90）=362（元） 所以他在A,B两个超市都可买,但A更便宜 6. A4(16,3) B4(32,0) An((-2)^n,(-1)^n*3) Bn((-2)^n*2,0) 1.A 2.C 3.A 4.小红的意思：同位角相等两直线平行 小花的理由：内错角相等两直线平行 另一组平行线：AB//CE 理由：∠ABC=∠ECD →AB//CE （ 同位角相等两直线平行） 5.设2元x张,则5元58-20-7-x 张 2x+5（58-20-7-x）+20+10*7=200 x=15 2元15张,则5元16张 6. (1) SΔABC=SΔABP,SΔAPC=SΔBPC,SΔAOC=SΔBOP (2) SΔABC=SΔABP, 同底等高的三角形面积相等 （3）连接EC,过点D作EC的平行线,平行线交CM于点F. EF就是满足要求的直路. （3）理由 因为平行线与EC平行,所以点D到EC的距离【三角形ECD在边EC上的高】=点F到EC的距离【三角形ECF在边EC上的高】. 三角形ECD的面积=三角形ECF的面积. 所以, 五边形ABCDE的面积 = 四边形ABCE的面积 + 三角形ECD的面积 = 四边形ABCE的面积 + 三角形ECF的面积. 因此,直路EF满足要求. 不知道这是不是你要的【2018七年级下册暑假生活答案】

2018七年级下册暑假生活答案（六）：

暑假生活指导（山东七年级）-身边的历史（p55）.假如你生活在隋朝,乘船沿大运河从余杭到涿郡要依次经过哪几段运河?经过今天的哪些省份?能看到今天的哪几座大城市?
答：
(从南至北)依次经过江南河、刊沟、通济渠、永济渠 .
经过省份（从南至北）：浙江、江苏、安徽、河南、山东、河北、天津、北京.
看到大城市：杭州、扬州、洛阳、北京等.
2.大运河申报世界遗产理由?
首先大运河是隋朝隋炀帝下令建造,是中华人民汗水和历史的结晶,在其建造成后的很长时间内,对中华南北文化,南北经济发展起到了极大的促进作用,对形成有多种文化元素的中国文化起到极其重要的作用,特别是对后来中国经济重心的南移也起到重要作用,其对中国历史的发展有不可磨灭的影响.
