How much does it cost in dollars to watch the 5.00 hour-long coverage of the Super Bowl on a 115 Watt television set? Assume that one kWh electricity costs 9.41 cents.
energy=5hr*.115kw
cost=energyinKW-hrAbove*9.41 cents/kwhr
To calculate the cost of watching the Super Bowl on a 115 Watt television set for 5.00 hours, we need to find out the total energy consumed in kilowatt-hours (kWh) and then multiply it by the cost per kWh.
First, let's convert the power of the television set from Watts to kilowatts (kW). There are 1000 Watts in 1 kilowatt, so we divide 115 Watts by 1000 to get 0.115 kW.
Next, we need to calculate the total energy consumed by multiplying the power (0.115 kW) by the time (5.00 hours). This will give us the energy in kilowatt-hours (kWh). So, 0.115 kW x 5.00 hours = 0.575 kWh.
Finally, we can find the cost by multiplying the energy consumption in kWh (0.575 kWh) by the cost per kWh (0.0941 dollars/kWh). This gives us: 0.575 kWh x 0.0941 dollars/kWh = 0.0541 dollars.
Therefore, it would cost approximately 0.0541 dollars to watch the 5.00 hour-long coverage of the Super Bowl on a 115 Watt television set.
