Provide an appropriate response.Tell whether the statement is true or false. If it is false, give the correct answer. Explain your answer. The easiest way to simplify the expression 
is to multiply both the numerator and denominator by 1 + 
What will be an ideal response?
Tank A contains 50 lbs of salt dissolved in 500 gal of water. Tank B contains 100 lbs of salt dissolved in 500 gal of water. The mixture from tank A is pumped to tank B at the rate of 250 gal per hr, while the mixture from tank B is pumped to tank A at the same rate. Assume that the mixture in each tank is uniform by stirring. Let A(t ) and B(t ) be the amount of salt in tanks A and B after t hours, respectively.
(a) Draw a two-compartment model for A(t ) and B(t ) . (b) Use the initial conditions A(0) = 50 and B(0) =100 to solve for A and B. (c) What are the equilibrium values of A and B?
