A dead body was found within a closed room of a house where the temperature was a constant 65° F. At the time of discovery the core temperature of the body was determined to be 80° F. One hour later a second measurement showed that the core temperature of the body was 75° F. Assume that the time of death corresponds to t = and that the core temperature at that time was 98.6° F. Determine how many hours elapsed before the body was found. [Hint: Let t₁ > 0 denote the time that the body was discovered.] (Round your answer to one decimal place.) 1.6 Xhr
a tank contains 50kg of salt and 1000 L of water. A solution of a concentration 0.025 kg of salt per liter enters a tank at the rate 9L/min. The solution is mixed and drains from the tank at the same rate. what is the concentration of our solution in the tank initially concentration = ? (kg/L) find the amount of salt in the tank after 3 hours. amount = ? kg c) Find the concentration of salt in the solution in the tank as time approaches infinity. concentration = ? (kg/L)
Drinking water is treated with fluoride before it is made available to the public. The ideal level is 0.7 ppm. A 20,000 gallon mixing tank is half full and contains 2 lb of fluoride. Fresh water enters from the lake at 2 gallons per minute. If the tank is dis- charged at 1 gallon per minute, how many pounds of fluoride is in the tank the moment it is full? Is it safe to drink using the conversion 1 lb/gal (US) = 119826 ppm?
The stopping distance d (in feet) for a car traveling v mph when the driver has a reaction time of t is given by d = 1.5tv + 0.06v². A car is traveling 70 mph. If the driver's reaction time is 0.5 sec, what is the stopping distance? ft
