Exact Form: 
Mixed Number: 
Decimal Form: 1.6(this is a repeating decimal)
The answer is A. 1 2/3
144/12 is 12. This means 12 goes into 144, 12 times.
AD => Cos 20 = 12.6/H => H = 12.6/Cos 20 = 13.4cm
AB => √13.4^2 - 12.6^2 = 4.6 cm
BC = √19.3^2 - 12.6^2 = 14.6 cm
AC = 14.6 + 4.6 = 19.2 cm
A. Because Belle worked for 35hrs and she earns $12 per hour, which makes $420. Then Belle sold 2550 in cosmetics and 5% in decimals equals 0.05. Multiply 2550 by 0.05 and you get $127.50, that is the 5% commission for the 2550 Belle sold. Lastly add the $420 and $127.50 and you get $547.50 which is answer A.
