Answer:
q = 5/108
Step-by-step explanation:
q varies directly as r and inversely as cube of s
q = kr/s³ where k is the constant of variation
if q = 5, r = 1 and s = 1/2
q = kr/s³
5 = k ( 1 ) / ( 1/2 ) ³
5 ( 1/2 ) ³ = k ( 1 )
k = 5 ( 1/8 )
k = 5/8
if r = 2 and s = 3, find q.
q = ( 5/8 ) ( 2 ) / 3³
q = ( 10/8 ) / 27
q = 10/8 * ( 1/27 )
q = 10/216 ÷ 2/2
