Algebra.Com's Answer #124014 by hobbitt(2)![]() ![]() ![]() You can put this solution on YOUR website! I'm not sure how they wrote the formula - but when I looked it up it said \"fraction of the adult dose obtained by dividing the age of the child at the nearest birthday by 24\"\r \n" ); document.write( "\n" ); document.write( "as the adult dose is 600 and the child dose is 200 and we have \r \n" ); document.write( "\n" ); document.write( "d=D*((a+1)/24) I think you were saying \r \n" ); document.write( "\n" ); document.write( "d/D will = age + 1 divided by 24\r \n" ); document.write( "\n" ); document.write( "so 200/600 = 1/3 \r \n" ); document.write( "\n" ); document.write( "so now we have 1/3 on one side and (age +1)/24 on the other side\r \n" ); document.write( "\n" ); document.write( "multiply both sides by 24 to give 24/3 = age = 8 I think \n" ); document.write( " |
