Step-by-step explanation:
$40/12 = unit rate simplify = 10/3
$10/3 per book
18 * 10/3 = $60 for 18 copies
Answer:
anglePUM = 3° , PM = 5, UM = √75
Step-by-step explanation:
anglePUM = 180 - 60 - 90 = 30° (∠sum of Δ)
cos60 = PM/10
PM = 10cos60 = 5
sin60 = UM/10
UM = 10sin60 = √75
The simplification of the given expression
will be equal to
