A light bulb consumes 1800 watt-hours per day. How many watt-hours does it consume in 4 days and 12 hours?
In 4 days, the light bulb consumes 1800 watt-hours/day x 4 days = <<1800*4=7200>>7200 watt-hours.
In 12 hours, the light bulb consumes an additional 1800 watt-hours/day x 12 hours/24 hours = <<1800*12/24=900>>900 watt-hours.
Therefore, the light bulb consumes a total of 7200 watt-hours + 900 watt-hours = <<7200+900=8100>>8100 watt-hours in 4 days and 12 hours. Answer: \boxed{8100}.
To determine the total watt-hours consumed by the light bulb in 4 days and 12 hours, we can follow these steps:
1. Calculate the number of watt-hours consumed in 4 days:
Number of watt-hours consumed per day = 1800 watt-hours
Number of days = 4
Total watt-hours consumed in 4 days = Number of watt-hours consumed per day x Number of days
Total watt-hours consumed in 4 days = 1800 watt-hours/day x 4 days = 7200 watt-hours
2. Calculate the number of watt-hours consumed in 12 hours:
Number of watt-hours consumed per day = 1800 watt-hours
Number of hours = 12
Number of watt-hours consumed in 12 hours = Number of watt-hours consumed per day / 24 hours x Number of hours
Number of watt-hours consumed in 12 hours = 1800 watt-hours / 24 hours x 12 hours = 900 watt-hours
3. Add the results from step 1 and step 2 to determine the total watt-hours consumed in 4 days and 12 hours:
Total watt-hours consumed = Total watt-hours consumed in 4 days + Number of watt-hours consumed in 12 hours
Total watt-hours consumed = 7200 watt-hours + 900 watt-hours = 8100 watt-hours
Therefore, the light bulb consumes 8100 watt-hours in 4 days and 12 hours.
To calculate the total watt-hours consumed in 4 days and 12 hours, we need to first convert the 12 hours into a fraction of a day, then multiply it by the daily consumption and add it to the consumption of 4 full days. Here's how you can do it:
1. Calculate the energy consumption in 4 full days:
- Energy consumption per day = 1800 watt-hours
- Energy consumption in 4 days = 1800 watt-hours/day * 4 days = 7200 watt-hours
2. Calculate the energy consumption in 12 hours:
- Energy consumption per day = 1800 watt-hours
- Fraction of a day in 12 hours = 12 hours / 24 hours = 0.5 (since there are 24 hours in a day)
- Energy consumption in 12 hours = 1800 watt-hours/day * 0.5 = 900 watt-hours
3. Total energy consumption in 4 days and 12 hours:
- Total energy consumption = Energy consumption in 4 days + Energy consumption in 12 hours
- Total energy consumption = 7200 watt-hours + 900 watt-hours = 8100 watt-hours
Therefore, the light bulb consumes 8100 watt-hours in 4 days and 12 hours.
