Algebra.Com's Answer #626249 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! Distance formula is square root of the sum of the x and y distances squared. They may be done in either direction. The whole distance rs=sqrt (400=2250=sqrt 625=25. \n" ); document.write( "for st it is sqrt (11-2)^2+(10+2)^2=sqrt (225)=15 \n" ); document.write( "for rt it is sqrt(2+4)^2+(-2+10)^2=sqrt(100)=10 \n" ); document.write( "The ratio is 10/15 or 2/3 ANSWER \n" ); document.write( " |
