Salt water flows at a constant rate of 6 L/min into atank that initially held 100 L of salt solution in whichwas dissolved 0.5 kg of salt. The solution inside thetank is kept well stirred and flows out of the tank atthe same rate. If the concentration of salt in thesolution entering the tank is 0.05 kg/L.a) Determine the mass of salt in the tank after t min.b) When will the concentration of salt in the tankreach 0.03 kg/L?a) Determine the mass of salt in the tank after t min.mass= kgb) When will the concentration of salt in the tankreach 0.03 kg/L?The concentration of salt in the tank will reach 0.03kg/L after minutes.(Round to two decimal places as needed.)

Oil flows at a constant rate of 10L/min into a tank that can hold 40L of liquid. Initially the tank held 20 L of brine solution, which dissolved 2kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at a rate of 8 L/min. Find the amount of salt in the tank when the tank is full.
A tank contains 200 liters of fluid in which 30 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then pumped into the tank at a rate of 4 L/min; the well-mixed solution is pumped out at the same rate. a) Find the number A(t) of grams of salt in the tank at time t. b) Repeat part a, assuming that pure water is pumped into the tank. 200 L
A tank initially have 100 L with 50 g of dissolved salt. brine is pumped into the tank at a rate of 2 L/min carrying 2 grams of salt per liter. The well-stirred mixture is pumped out of the tank at a rate of 3 L/min. Find the concentration of the solution after 1 hour.
A student is concerned with the amount of air pollution students are exposed to in the school's parking lot after school. The student conducts an investigation to compare the quantity of particulate matter released from the diesel-powered buses, natural gas-powered buses, and the large and small cars as they idle waiting to pick up students. To make measurements, a small piece of white fabric is used to collect particulate matter from the tailpipe of each vehicle as it idles for five minutes. Each piece of fabric is then analyzed to measure the amount of particulate matter it collected. (i) Identify the independent variable in the investigation. (j) Identify one variable that was not mentioned in the description that could affect the results of the investigation. (k) Describe a realistic alternate sampling method to collect particulate matter from the vehicles in the investigation. (1) The student wants to ensure that the results are reliable. Explain how the student could modify the…
