6 answers
24in : 1454ft = 2ft : 1454ft = 1:727
24 inches = 2 feet
2/1454
2/1454
1) 1 : 727
2) JKML ~ PQRS; 8 : 4.8
3) GFH ~ GHI ~ HIF
4) x = 9/4 y = 15/4
5) 15.7
6) Never
7) No (prolly wrong but fingers crossed)
8) 78 w/ square root sign
9) 27
10) 105 w/ a square root sign
11) m=25
12) x=20
Your on your own w/ the other ones, sorry. Also sorry if any are wrong, this is just what I'm abt to put in for my test.
