2011年宁夏回族自治区初中毕业暨高中阶段招生考试数学试题参考答案1.B 【解析】本题考查整式的加减,整式加减的实质是合并同类项,合并同类项时字母及其指数不变,系数相加减,a 2+3a 2=4a 2,所以本题选B .2.C 【解析】本题考查矩形的性质及锐角三角两数值的应用.根据矩形的性质可知∠DBA=30 °,AB=3AD=23,本题选C .3.B 【解析】本题考查等腰梯形的性质,30°角所对的直角边等于斜边的一半.作DE ⊥BC 于E ,AF ⊥BC 于F ,由CD=4.∠B=∠C=60°,得BF=CE=2,所以等腰梯形的下底是2+2+2=6,本题选B .4.B 【解析】本题考查数字问题,列方程解应用题,若个位数字为x 代表x ,十位数字为y 代表10y ,百位数字为b 代表100b .根据题意得⎩⎨⎧+=++=+y x x y y x 1018108,本题选B5.B 【解析】本题考查正方体的空间立体图形与平面展开图的对应关系,解决这种类型试题的一般方法:一是根据正方体展开图的特点,通过空间想象得出答案;二是通过动手折叠或展开正方体确定正确结果;三是注意无公共顶点的不相邻的面.本题可确定和“创”相对的字是“明”,故本题选B .6.C 【解析】本题考查圆与圆的位置关系,设两圆的半径分别为R ,r ,两圆心的距离为d ,当圆心距d >R+r 时,两圆外离;当圆心距d =R+r 时,两圆外切;当圆心距R 一r <d <R+r 时,两圆相交;当圆心距d =R —r 时,两圆内切;当圆心距d <R —r 时,两圆内含.此两圆相切可能是外切也可能是内切,所以圆心距为2或8,本题选C .7.D 【解析】本题考查平均数、方差的计算,A x =(176+175+174+171+174)÷5=174,B x =(170+173+171+174+182)÷5=174;2A s =51[(176—174)2+(175—174)2+(174—174)2+(171—174)2+(174—174)2]=514,2B s =51 [(170—174)2+(173—174)2+(171—174)2+(174—174)2+(182—174)2]=18,所以A x =B x ,2A s <2B s ,故本题选D .8.B 【解析】本题考查图形的旋转变换,先根据题意画出旋转后的图形,再根据图形写出点的坐标,将△ABO 绕点O 按逆时针方向旋转90°,得到点A’,B ’的坐标分别为(一4,1)、(一1,2),故本题选B .9.a (a +1)(a 一1) 【解析】本题考查因式分解,因式分解的步骤:一提公因式;二用公式.a 3一a =a (a 2—1)=a (a +1)(a 一1).10.4一2【解析】本题考查学生的数形结合能力,根据题意画出草图,然后计算.AB 的距离为2一2,所以BC 的距离为2一2,所以C 点的坐标为2+2一2=4一2.11.(0,1)【解析】本题考查线段的平移,由点A 的对应点C 的坐标可以得到平移规律为向右平移5个单位,再向上平移3个单位,把点B 的坐标向右平移5个单位,再向上平移3个单位,得到点D 的坐标为(0,1).12.40【解析】本题考查学生列不等式解决实际问题的能力,设最多为x 人,则15x +300≤900,解得x ≤40,所以参加这次活动的学生人数最多是40.13.36(1一m %)2=25【解析】本题考查列方程解决实际问题的能力,根据题意得36(1一m %)2=25.14.350【解析】本题考查圆中角的关系及等腰三角形的性质,∠OAB=∠B =∠D=350. 15.10【解析】本题考查平行线分线段成比例,由DE//AB ,密封线密封 线得524=+===AB CD CD CA CD AB AB DE ,解得AB=10 16.9.42【解析】本题考查三视图的识别与计算,首先根据三视图判断此几何体为圆锥,圆锥底面圆周长为2π,面积为π,侧面面积为21×底面圆周长×母线长=21×2π×2=2π,所以这个几何体的全面积为π+2π=3π≈9.42.17.本题考查实数的计算,注意负指数幂等于正指数幂的倒数;非零数的零次方等于1.解:原式:1—3×33+9一(2一3) (4分) =1一3+9—2+3 =8. (6分)18.本题考查分式方程的解法,首先两边乘以最简公分母,化分式方程为整式方程,然后解整式方程,最后要检验.解:两边同乘(x 一1)(x +2),得x (x +2)一(x 一1)(x +2)=3(x 一1), (2分) 整理得2x =5,解得x =25. (5分) 经检验x =25是原方程的根. (6分) 19.本题考查不等式组的解法,首先解两个不等式,再根据数轴或两不等式的解集写出不等式组的解集.解:解①得x ≥1, (2分)解②得x <8, (4分)∴不等式组的解集为1≤x <8. (6分)20.本题考查用列表法或画树状图法求概率.解:(1)用列表法:(4分) 或画树状图:(4分)(2)由列表或画树状图知S 的所有可能情况有18种,其中S<2的有5种, ∴P (S<2)=185. (6分) 21.本题考查统计的有关概念、计算及利用统计知识指导社会生活. 解:(1)抽取的样本容量为200,表中m 的值为0.3.(2分)(2)“非常了解”的频数在扇形统计图中所对应扇形的圆心角的度数为3600×0.2=72°. (4分)(3)结合表中统计的数据,利用统计的语言叙述合理.(6分) 22.本题考查平行四边形的判定,可以有多种方法. 解法一:∵DF//BE ∴∠DFA=∠BEC ,∴∠DFC=∠BEA . (2分)在△ABE 和△CDF 中,∵DF=BE ,∠DFC=∠BFA ,AE=CF , ∴△ABE ≌△CDF (SAS ). (3分) ∴∠EAB=∠FCD ,AB=CD ,∴AB//CD , ∴四边形ABCD 是平行四边形. (6分) 解法二:∵DF//BE ,∴∠DFA=∠BEC . (2分)∵AE=CF ,∴AE+EF=CF+EF ,即AF=CE , 在△AFD 和△CEB 中,∵DF=BE ,∠DFA=∠BEC ,AF=CE , ∴△AFD ≌△CEB (SAS ), (3分)∴AD=CB ,∠DAF=∠BCE ,∴AD//CB ∴四边形ABCD 是平行四边形。
