Problema Solution
If a is inversely proportional to b, and a=13 when b= 21, what is b, when a =33
Answer provided by our tutors
a is inversely proportional to b when a decreases at the same rate that b increases
a*b = k, where k is constant
13*21 = 33*b
b = (13*21)/33
b = 91/11
b = 8 3/11
b = 8.27 approximately.
