Problema Solution
An alligator's tail length, T, varies directly as its body length, B. an alligator with a body length of 4.8 feet has a tail length of 4.2 feet. What is the tail length of an alligator whose body length is 5.6 feet?
Answer provided by our tutors
Its written T varies directly with body length B,/
means linearly proportional,
we can write
T is proportional to B.
or
T=k*B ( where k= constant of proportionality)
now
T1=4.2 feet when B1=4.8 feet
k=42/48=7/8
So
T2=k*B2=(7/8) *5.6=7*0.7=4.9 feet
