A water heater in the shape of a circular cylinder is standing vertically, resting on one of the round ends. The tank is 60 inches tall and has a volume of 30 gallons. If water is flowing into the tank at the rate of 5 gallons per minute, at what rate is the level of the water...
The graph of the equation 2x+6y=4 passes through point (x,-2). What is the value of x?
Solution My mean is 175.5 My standard deviation is=90.57 Sample=25 So the probability is Formula to be used: P(X>190)=P((X-mean)/s sqrt of my sample is = 5 (190-175.5) / 90.57/5) 14.5 / 18.114 calculator says 0.8004858120790548746825659710721 I check the z-table and I see -...
134 g of water at 7°C is added to ice at 0°C. If the final temperature of the system (which you can assume is isolated) is 0°C, determine HOW MUCH ICE MELTED. The specific heat of water is 4186 J/kg·°C. The latent heat of fusion for H2O is 335,000 J/kg.
The answer is 0
Steam of mass 11.0 g at 100°C is added to 114.8 g of ice at 0.00°C. Find the final temperature of the system.
