Edna puts 250L of 48oC water into the bathtub by turning on only the hot water faucet. She then adds more water by turning on only the cold water faucet (water at 7oC). How many liters of cold water must Edna add so that the bathwater reaches a comfortable temperature of 38oC? [Bonus: Will the bathtub overflow? The manufacturer told Edna it was an 80-gallon tub.]

A bathtub contains 65 gallons of water and the total weight of the tub and water is approximately 861.425 pounds. You pull the plug and the water begins to drain Let v represent the number of gallons of water that has drained from the tub since the plug was pulled. Note that water weights 8.345 pounds per gallon. a. Write an expression in terms of u that represents the weight of the water that has drained from the tub (in...

A bathtub holds 135 L of hot water at 41.0°C. Cold water at 13.0°C is added to the bathtub until the water reaches a final equilibrium temperature of 38.5°C. Assuming only a negligible amount of energy is exchanged between the water and its environment during this time, determine the volume in liters (L) of the added cold water. The specific heat of water is 4.19 ✕ 103 J/(kg · °C) and its density is ρ = 1.00 kg/L. What is...

Applied UMB RS LDC) 1. A cylindrical hot tub is being filled by a hose that pours out water at a constant rate of 0.25m/min at 8:00 a.m. The volume of water in the pool was 8m and the radius of the hot tub is 2m. a) Determine the average rate of change with respect to its height between 9:00 a.m. and 10:00 a.m. b) Find the instantaneous rate of change at 10:00 a.m.

Sunland Company purchased a hot tub for $11,210 on January 1, 2016. Straight-line depreciation is used, based on a 6-year life and a $1,790 salvage value. In 2018, the estimates are revised. Sunland now feels the hot tub will be used until December 31, 2020, when it can be sold for $840. Compute the 2018 depreciation. Depreciation expense, 2018
