These are differential equation problems. Pease show clear and legible work.
Hope it helps you out there.
In case any doubt please feel free to ask.
I will be happy to help you.
Thanks.
Note: in case multiple questions, please post them separately, as we are having limited time to answer those, many problems.

2. A tank contains 100 gallons of pure water. Beginning at t O, a salt water solution containing 0.2 pounds of salt per gallon is pumped into the tank at a rate of 3 gallons per minute. At the same time, a drain is opened at the bottom of the tank which allows the mixture to leave the tank at a rate 3 gallons per minute. Assume the solution is kept perfectly mixed. (a) What will be concentration of salt...

Question 2 (32 points) A large tank is filled to capacity with 200 gallons of pure water. Brine containing 5 pounds of salt per gallon is pumped into the tank at a rate of 18 gallons per minute. The well-mixed solution is pumped out at the same rate. Find the amount of salt in pounds after 10 minutes. (round to the nearest tenth of a pound) Your Answer: Answer
A tank originally contains 100 gallons of fresh water. Water containing lb of salt per gallon is poured into the tank at a rate of 2 gallons per minute, and the mixture is allowed to leave at the same rate. After 10 minutes the salt water solution flowing into the tank suddenly switches to fresh water flowing in at a rate of 2 gallons per minute, while the solution continues to leave the tank at the same rate (a) Write...
13. A 600 gallon capacity tank initially contains 50 pounds of salt dissolved in 100 gallons of water. Water containing 2 pounds of salt per gallon enters the tank at a rate of 6 gallons per minute (assume the salt is evenly distributed throughout the water in the tank). Water is drained from the tank at a rate 4 gallons per minute. How many pounds (rounded to 1 decimal place) of salt will be in the tank when the tank...
Can you show all the steps please? A salt tank contains 50 lbs of salt dissolved in a 300 gallon tank. A brine mixture with a concentration of 2 lbs of salt per gallon is pumped into the tank at a rate of 3 gallons per minute. The mixture is distributed uniformly in the tank and the mixture is drained at the same rate of 3 gallons per minute input rate of brine 3 gal/min constant 300 gal A Set...
you need to include the ODE. the initial value, the solution to the IVP, and answer to the question. you'll need to leave the answer in terms of exponential and/or logarithms. A) a pizza is removed from an oven at a temperature of 400F. one minute later, the pizza of the temperature is 300F, if the room temperature is 70F, how long will it take the pizza to reach a temperature of 200F? B) A large tank is partially filled...

2. A tank initially contains 100 gallons of salt solution in which 20 pounds of salt is dissolved. Starting at time 0, a solution containing 3 pounds of salt per gallon flows into the tank at a rate of 4 gallons per minute. The mixture is kept uniform by stirring and the well-mixed solution simultancously flows out of the tank at the same rate. Determine the amount of salt in the tank after 10 minutes, when the amount of salt...
1. Find the differential equation and the corresponding initial condition modeling the following situation. However, do not solve the resulting initial value problem! A 500-gallon tank initially contains 200 gallons of sugar water that was made by dis- solving 8 pounds of sugar in the water. Sugar water with a concentration of 0.30 pounds of sugar per gallon is pumped into the tank at the rate of 10 gallons per minute, while the sugar water in the tank is pumped...
