(1)3; (2)9.(1)含甲和丙,而不含有乙的有36-25=11(种),只含有甲的有 62-48-11=3(种).(2)由容斥原理知,至少含甲、乙、丙一种的有 62+90+68-48-36-50+25=111(种).故不含甲、乙、丙三种的有120-111=9(种).10. 18.因为这个三位数是5的倍数,故它的末位应该为5或0.若它的末位为0,因这个三位数又是9的倍数.故百位与十位有9种可能:18,27,90.即这样的三位数有9个.若它的末位为5,同样,因为这个三位数是9的倍数.故它的前两位数字之和为4或13.这时有如下9种可能:13,31,40,49,58,67,76,85,94.即这样三位数也有9个.故这样的三位数一共有9+9=18(个).11. 设正确答案为,则12.3912.50,是十三个自然数的平均数,它的13倍应为一个自然数:.但1611312.38, 1621312.46.故应判断近似值为126,.12. 设“从小爱数学”=,则应为100000的倍数.即与的末五位数字相同,它们的差是100000的倍数.因是两相邻整数,且它们互盾.又100000=323125,故与中奇数是3125的倍数,偶数是32的倍数.由算式中不难看出,“小”=0,故能被3125整除的五位数中仅40625和90625符合.与它们相邻的数为40624、40626或90624、90626.但此四数中仅90624是32的倍数.故所求的数为90625.13. (1)223(10-5)=60,601=60(秒). (2)88(10+5)- 22310=840. (3)底面积882=128; 外侧面的面积为8(10+5)4=480; 内侧面积为4310=120; 表面积为128+480+120=728.14. 由已知,有,且有:.故,.用1000除以89直到首次余88为止,不难求出:112359550561797752809.附送：2019年小升初分班考试英语真题一用is, am 或are 填空1.Excuse me.
