4行依據(jù)"行,列"的形式給出答案:(25,20)參照答案：1、Wednesday詳解：In2004,16JunefallsonaWednesday.Onwhatdayoftheweekwill16Junefallin2010?翻2004年6月16號是禮拜三，那么2010年6月16號是禮拜幾呢？2004年6月16號是禮拜三，那么2010年6月16號是禮拜幾呢？仍是禮拜三平年365÷7=521閏年366÷7=522所以若第二年為平年，則那年的今日禮拜序號是現(xiàn)年今日后一天；閏年則后兩天。2005，2006，2007，2009，2010為平年，2008為閏年于是加起來應(yīng)當(dāng)多7天，即一個禮拜，所以仍是禮拜三2、453、27（求數(shù)位上上的數(shù)字之和）4、28=9+9+10，所以答案為8105、503-20=483483=3×7×23＝21×23，所以□x＝483，所以本題余數(shù)是10.6、D7、25，20小升初英文奧數(shù)題[2]1、Didyouknow?Inthedecimalnumbersystem(base10)tendifferentdigits,0to9,areusedtowriteallthenumbers.Inthebinarynumbersystem(base2)twodifferentdigitsareused,i.e.0and1.Whichoneofthefollowingnumbersisnotavalidnumberintheoctalnumbersystem(base8)?A)128B)127C)126D)125E)1242、Thenumberofdiagonalsthatcanbedrawninaregularpolygonwithtwentysides(icosagon)is_____.3、Ifaandbareintegers,10?3=1,152?7=3,andthen379?6isequalto_____.4、Twonumbersareintheratio2:3.When4isaddedtoeachnumbertheratiochangesto5:7.Thesumofthetwooriginalnumbersis____.5、ThegreatestnumberofMondayswhichcanoccurin45consecutivedaysis____6、Saulplaysavideogameinwhichhescores4forahitandlost6foramiss.After20roundshisscoreis30.Thenumberoftimeshehasmissedis____.7、ThreegirlsA,BandCrunina100mrace.WhenAfinishes,Bis10mbehindAandwhenBfinishesCis20mbehindB.HowfarinmetreswasCfromAwhenAfinished?(Let’sassumealltheathletesrunataconstantspeed)8、Theareasofthefacesofarectangulaboxare84cm2,70cm2and30cm2.Thevolumeoftheboxincm3is____.9、Youhave3weights:1kg,3kgand9kgaswellasanequalarmbalance,asshown.Howmanydifferentweightobjectscanyouweighwiththesethree?[Remembertheweightsmaybeplacedoneitherside]參照答案：1、A觀察我們學(xué)過的簡單的進(jìn)制問題，明顯8進(jìn)制中沒有8出現(xiàn)2、170找規(guī)律，公式為n×（n-3）÷23、1定義新運(yùn)算，就是求379÷6的余數(shù)。4、40，16和245、76、57、28米，依據(jù)距1、離比求出速度比，三者的速度比為1：9/10：18/258、420分解質(zhì)因數(shù)9、13種小升初英文奧數(shù)題[3]1、Didyouknow?Inthedecimalnumbersystem(base10)tendifferentdigits,0to9,areusedtowriteallthenumbers.Inthebinarynumbersystem(base2)twodifferentdigitsareused,i.e.0and1.Whichoneofthefollowingnumbersisnotavalidnumberintheoctalnumbersystem(base8)?A)128B)127C)126D)125E)1242、Thenumberofdiagonalsthatcanbedrawninaregularpolygonwithtwentysides(icosagon)is_____.3、Ifaandbareintegers,10andthen3796isequalto_____.4、Twonumbersareintheratio2:3.When4isaddedtoeachnumbertheratiochangesto5:7.Thesumofthetwooriginalnumbersis____.5、ThegreatestnumberofMondayswhichcanoccurin45consecutivedaysis____6、Saulplaysavideogameinwhichhescores4forahitandlost6foramiss.After20roundshisscoreis30.Thenumberoftimeshehasmissedis____.7、ThreegirlsA,BandCrunina100mrace.WhenAfinishes,Bis10mbehindAandwhenBfinishesCis20mbehindB.HowfarinmetreswasCfromAwhenAfinished?(Let’sassumealltheathletesrunataconstantspeed)8、Theareasofthefacesofarectangulaboxare84cm2,70cm2and30cm2.Thevolumeoftheboxincm3?is____.9、Youhave3weights:1kg,3kgand9kgaswellasanequalarmbalance,asshown.Howmanydifferentweightobjectscanyouweighwiththesethree?[Remembertheweightsmaybeplacedoneitherside]參照答案：1、A觀察我們學(xué)過的簡單的進(jìn)制問題，明顯8進(jìn)制中沒有8出現(xiàn)2、170找規(guī)律，公式為n×（n-3）÷23、1定義新運(yùn)算，就是求379÷6的余數(shù)。4、40，16和245、76、57、28米，依據(jù)距離比求出速度比，三者的速度比為1：9/10：18/258、420分解質(zhì)因數(shù)9、13種小升初英文奧數(shù)題[4]1、Anantcoversadistanceof90metresin3hours.Theaveragespeedoftheantindecimetresperminuteis____.2、3、Inacertaintownsomepeoplewereaffectedbya’flu’epidemic.Inthefirstmonth20%ofthepopulationcontractedthefluwhilst80%werehealthy.Inthefollowingmonth20%ofthesickpeoplerecoveredand20%ofthehealthypeoplecontractedthedisease.Whatfractionofthepopulationishealthyattheendofthesecondmonth?4、Mpho,Barry,Sipho,EricaandFatimaaresittingonaparkbench.Mphoisnotsittingonthefarright.Barryisnotsittingonthefarleft.Siphoisnotsittingateitherend.EricaissittingtotherightofBarry,butnotnecessarilynexttohim.FatimaisnotsittingnexttoSipho.SiphoisnotsittingnexttoBarry.Whoissittingatthefarright?5、Ofthe28T?shirtsinadrawer,sixarered,fiveareblue,andtherestarewhite.IfBobselectsT?shirtsatrandomwhilstpackingforaholiday,whatistheleastnumberhemustremovefromthedrawertobesurethathehasthreeT?shirtsofthesamecolour?6、Inanalienlanguage,jalezborgfarnmeansmeans“mathsinharmony”anddarkoklarfarninthislanguage?
