given that m=999...99;2001 digits and n=888...88; 2001 digits, find the sum of the digits in the value of m*n
giúp với,mik cần gấp,viết lời giải!
The sum of the digits of m is 9*2001=18009
The sum of the digits of n is 8*2001= 16008
We have 1+8+0+0+9=18
1+6+0+0+8=15
18*15= 270
=> the sum of the digits in the value of m*n is 2+7+0 =9

Given the rectangle ABCD and the triangle BEC. Find the value of x such that the ratio of the area of the rectangle to the area of the triangle BEC is 7:3.
Answer: x = ....... cm.
ta co ti so:
\(\frac{S_{abcd}}{S_{bec}}=\frac{7}{3}\Leftrightarrow\frac{ab.bc}{\frac{x.bc}{2}}=\frac{7}{3}\Leftrightarrow\frac{2ab}{x}=\frac{7}{3}\)
\(\Leftrightarrow\)\(\Leftrightarrow\frac{2.7}{x}=\frac{7}{3}\Leftrightarrow\frac{2}{x}=\frac{1}{3}\Leftrightarrow x=6\)

câu 7 mk bấm nhầm đáp án là 120
qua B kẻ đường thẳng song song với AM cắt AC ở N.
vì AM là phân giác góc BAC nên có :
\(\dfrac{AC}{AB}=\dfrac{CM}{BM}=\dfrac{12}{6}=2\) suy ra \(\dfrac{CM}{BC}=\dfrac{CM}{CM+BM}=\dfrac{12}{12+6}=\dfrac{2}{3}\)
vì AM song song với BN nên có :
1,\(\dfrac{CA}{AN}=\dfrac{CM}{BM}=\dfrac{12}{AN}=2\) suy ra AN=6
2,\(\dfrac{AM}{BN}=\dfrac{CM}{BC}=\dfrac{2}{3}=\dfrac{4}{BN}\)suy ra BN=6
vì AB=6 nên tam giác ABN đều
suy ra \(\widehat{NAB}\)=\(60^0\)
mà \(\widehat{NAB}+\widehat{BAC}=\)\(180^0\)
nên \(\widehat{BAC}=\)\(120^0\)
