Question

How many kwh does a 200kw hairdryer use if its used for 30 min each day of the month?

whats the energy cost during the month, if the cost is 100 dabloons

Answer 1

it is 72 because you need to add them SUBTRACTING

Answer 2

To calculate the kWh, we need to convert the power consumption of the hairdryer from kW to kWh, and then multiply it by the number of hours it is used in a month.

Power consumption of hairdryer = 200 kW

Time used = 30 minutes/day = 0.5 hours/day

Total time used in a month = 0.5 hours/day x 30 days/month = 15 hours

Energy consumption in kWh = (200 kW x 15 hours)/1000 = 3 kWh

To calculate the energy cost, we can multiply the energy consumption in kWh by the cost per kWh.

Cost per kWh = 100 dabloons

Energy cost = 3 kWh x 100 dabloons/kWh = 300 dabloons

Therefore, the hairdryer uses 3 kWh of energy in a month and the energy cost is 300 dabloons.
