Số ko được dùng:2004.Bởi vì:2005+2008+2010+2011=8034.

                                                2006+2007+2009+2012=8034

Do số 2004 ko được nhắc đến trong bài nên đáp án là 2004

còn bài này ?

\(\frac{101010}{252525}\)= \(\frac{2}{5}\)

Nha bạn!

Họk Tốt!!!

Trả lời:

\(\frac{101010}{252525}=\frac{101010:505050}{252525:505050}\)

\(\Rightarrow\frac{101010}{252525}=\frac{2}{5}\)

TBC số km 1 xe đi trong 1 giờ là : 216 : 3 = 72 ( km )

                                                        Đáp số :...

20,08 x 35 + 20,08 x 64 + 21,08

= 20,08 x ( 35 + 64 ) + 21,08

= 20,08 x 99 + 21,08

= 1987,92 + 21,08

= 2009

20,08 * 35 + 20,08 * 64 + 21,08 = (20,08 * 35 )+ (20,08 * 64) + 21,08

                                                   = 702,8 +  1285,12 + 21,08

                                                   =2009

a) -Kẻ CH vuông góc với AB tại H

     Ta có: + diện tích ΔABC = 1/2 ×CH×AB

                + diện tích ΔAMC= 1/2×CH×AM

     Vì AB > AM ( AB =2AM)

=> diện tích ΔABC > diện tích ΔAMC

    - Kẻ MN vuông góc với DC tại N

=> MN=CH 

     Ta có : S ΔAMC= 1/2×CH×AM

                S ΔAMD= 1/2×MN×Am

     Vì MN=CH ( cmt)

=> diện tích ΔAMC = diện tích ΔAMD

   - Ta có : S ΔMDC=1/2×MN×CD

                 S ΔAMD=1/2×MN×AM

     Vì CD > AM ( vì AB = CD, AM < AB)

=> diện tích ΔMDC > diện tích ΔAMD

Bài này dài quá lười lm có j tự lm câu b và câu c nhé !!!!

_Học tốt_
