2015年山東省七下《暑假生活指導(dǎo)》答案 完整版(2)

時間: 雪珠2 初一語文

  800+s/v=45

  800-s/v=35 解得v=20 s=100

  1. 解:1.設(shè)計(jì)劃新建校舍X平方米,則拆除校舍為7200-X平方米.

  根據(jù)題意列出方程:

  80%X+(1+10%)(7200-X)=7200

  8X+11(7200-X)=72000

  3X=79200-72000

  X=2400

  計(jì)劃拆除校舍:7200-X=7200-2400=4800(平方米)

  答:計(jì)劃新建校舍和拆除校舍各為2400平方米和4800平方米.

  2.

  計(jì)劃新建校舍用的資金:700*2400=1680000(元)

  計(jì)劃拆除校舍用的資金:80*4800=384000(元)

  計(jì)劃在新建和拆除校舍中用的資金共:1680000+384000=2064000(元)

  實(shí)際新建校舍用的資金:80%*2400*700=1344000(元)

  實(shí)際拆除校舍用的資金:(1+10%)*4800*80=42240(元)

  實(shí)際新建和拆除校舍用的資金共:1344000+4240=1386240(元)

  節(jié)省的資金為:2064000-1386240=677760(元)

  節(jié)省的資金用來綠化的面積:677760/200=3388.8(平方米)

  答:在實(shí)際完成的拆建工程中,節(jié)余的資金用來綠化是3388.8平方米.

  2. 解:設(shè)活動前Ⅰ型冰箱為x臺,則Ⅱ型冰箱為960-x臺

  x(1+30%)+(960-x)(1+25%)=1228

  解得x=560

 ?、裥捅?560臺

 ?、蛐捅洌?00臺

  (2)Ⅰ型冰箱:560*(1+30%)=728臺

 ?、蛐捅洌?228-728=500臺

  13%(728*2298+500*1999)

  ≈3.5*10五次方

  3. 設(shè)要用8m的水管X根,5m的水管Y根

  8X+5Y=132

  因?yàn)?32-8X是5的倍數(shù),所以8X的尾數(shù)是2或7(尾數(shù)為7是單數(shù),不會是8的倍數(shù),不考慮尾數(shù)7)

  所以X的尾數(shù)為4或9,且X≤132/8=16.5

  所以X可選4;9;14三種,相對Y分別為20;12;4

  即有3種方案: 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的單價50/8元/M<5m的單價35/7元/m

  所以選8m管用得最多的方案最省錢,即選 8m的14根 5m的4根

  1. 解

  梨每個價:11÷9=12/9(文)

  果每個價:4÷7=4/7(文)

  果的個數(shù):

  (12/9×1000-999)÷(12/9-4/7)=343(個)梨的個數(shù):1000-343=657(個)梨的總價:

  12/9×657=803(文)

  果的總價:

  4/7×343=196(文)

  解:設(shè)梨是X,果是Y

  x+y=1000

  11/9X+4/7Y=999

  解得:X=657;Y=343

  即梨是657個,錢是:657*11/9=803

  果是343個,錢是:343*4/7=196

  2.解:設(shè)樹上有x只,樹下有y只,則由已知的,得:

  y-1/x+y=1/3

  x-1/y+1=1

  解得x=7;y=5

  即樹上有7只,樹下有5只。

  1. C

  2. C

  3. 120°

  4. 解:∠AMG=∠3.

  理由:∵∠1=∠2,

  ∴AB∥CD(內(nèi)錯角相等,兩直線平行).

  ∵∠3=∠4,

  ∴CD∥EF(內(nèi)錯角相等,兩直線平行).

  ∴AB∥EF(平行于同一條直線的兩直線平行).

  ∴∠AMG=∠5(兩直線平行,同位角相等).

  又∠5=∠3,

  ∴∠AMG=∠3.

  5. .(1)設(shè)隨身聽為x元,書包為y元,

  x+y=452 x=4y-8 將2代入1得 4y-8+y=452,解之得y=92,x=360

  (2)若在A買的話要花費(fèi)452*0.8=361.6(元)

  若在B買要花費(fèi)360+(92-90)=362(元)

  所以他在A,B兩個超市都可買,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.小紅的意思:同位角相等兩直線平行

  小花的理由:內(nèi)錯角相等兩直線平行

  另一組平行線:AB//CE 理由:∠ABC=∠ECD →AB//CE ( 同位角相等兩直線平行)

  5.設(shè)2元x張,則5元58-20-7-x 張

  2x+5(58-20-7-x)+20+10*7=200 x=15

  2元15張,則5元16張

  6. (1) SΔABC=SΔABP,SΔAPC=SΔBPC,SΔAOC=SΔBOP

  (2) SΔABC=SΔABP, 同底等高的三角形面積相等

  (3)連接EC,過點(diǎn)D作EC的平行線,平行線交CM于點(diǎn)F.

  EF就是滿足要求的直路。

  (3)理由

  因?yàn)槠叫芯€與EC平行,所以點(diǎn)D到EC的距離【三角形ECD在邊EC上的高】=點(diǎn)F到EC的距離【三角形ECF在邊EC上的高】。

  三角形ECD的面積=三角形ECF的面積。

  所以,

  五邊形ABCDE的面積 = 四邊形ABCE的面積 + 三角形ECD的面積

  = 四邊形ABCE的面積 + 三角形ECF的面積.

  因此,直路EF滿足要求。

  有道理的,三多,都是99條,一少指3條(又指三個秀才),并且都是單數(shù)。這種題有多種分發(fā)。不過這種有一些含義,其他的只是做題。
