1 gallon = 3.78 liters
Volume in liters= 231 liters
Volume in gallons = 231/3.78 = 61.11 gallons
= 61 gallons
A truck driver filled her gasoline tank with 231 liters of gasoline. Which of the following...
Assume it takes 6.00 min to fill a 20.0-gal gasoline tank. (1 US. gal = 231 in.3) (a) Calculate the rate at which the tank is filled in gallons per second. (b) Calculate the rate at which the tank is filled in cubic meters per second. (c) Determine the time interval, in hours, required to fill a 1.00-m3 volume at the same rate. (1 U.S. gal 231 in.3)
(1) A tank is filled with 300 liters (L) of contaminated water initially containing 3 kg of toxin. Pure water is pumped in to the tank at a rate of 40 L/min, mixes instantaneously, and the mixture is pumped out at the same rate (40 L/min). Let y(t) be the amount of toxin present in the tank at time t. Write the differential equation and the initial value that models this scenario. (a) Find the particular solution, y(t). Put a...
Suppose Peggy consumes only two goods, gasoline and cigarettes. Her income is $120, the price of cigarettes per pack is $4 and the price of gasoline per gallon is $2. Currently, she consumes 40 gallons of gas at optimal level. a) Sketch the following budget lines. Be sure to show how you calculated the slopes and end points. (Put gas on the X axis.). b) What is optimal level consumption of cigarettes for Peggy? Use an arbitrary convex indifference curve,...
These are differential equation problems. Pease show clear and
legible work.
A 100 gallon tank is filled with a salt solution containing 10 lbs of salt. Pure water is pumped in at a rate of 5 gallons per minute and pumped out at the same rate. How many minutes will it take the amount of salt to drop to 2 lbs? Round to one decimal place. A 200 gallon tank initially has 100 gallons of a salt solution that contains...
1. Suppose Gerte Guzzler has a daily income of $80. Gerte allocates her income between gasoline, which she uses on her daily commute to work, and clothing, which she wears to work. The price of gasoline is $5 per unit (1 unit = 5 gallons) and the price of clothing is $2 per unit. a. How is Gerte affected by a government plan to ration gasoline to 5 units per day? Explain. Use a graph of the consumer choice model...
A Water Tank Problem with Discontinuous Source A water tank contains V, > 0 liters of pure water and Qo grams of salt. At time t = 0 we start pouring water into the tank with a rate r > 0 liters per minute with a salt concentration of q> 0 grams per litter, and we let the well-stirred water leave the tank at the same rate. After T > 0 minutes the process is stopped and fresh water is...

A researcher wanted to study the effect of a newly developed gasoline additive (Additive X) on automobile mileage (miles per gallon, MPG). To gather information, a random sample of cars has been selected. For each car, the MPG was measured both when gasoline with Additive X is used and when gasoline without Additive X is used. The order of the two treatments (with Additive X versus without Additive X) was randomized and care was taken so that there was no...
