An electric heater has a power of 1100W. At a rate of 8¢ per kWh, how much does it cost to use the heater 3 hours a day for 30 days?

Answers

Answer 1

It will cost $7.92 to use the electric heater for 3 hours a day for 30 days at a rate of 8¢ per kWh.

To calculate the cost of using the electric heater for 3 hours a day for 30 days, we need to determine the energy consumption in kWh first.

The power of the electric heater is given as 1100W, which means it consumes 1.1 kWh of energy per hour (since 1 kWh = 1000W). Therefore, the energy consumption in 3 hours is 3.3 kWh (1.1 kWh x 3 hours).

Now, we can calculate the total energy consumption for 30 days, which is 99 kWh (3.3 kWh x 30 days).
Using the given rate of 8¢ per kWh, we can calculate the total cost of using the electric heater for 30 days as follows:

Total Cost = Energy Consumption x Rate per kWh

Total Cost = 99 kWh x 8¢

Total Cost = $7.92

Answers

The joint between the base of a toilet and the closet flange is sealed with a rubber or wax-ring seal. This is plumbing.

Why is this so?

A rubber or wax-ring seal is commonly used to seal the junction between the base of a toilet and the closet flange. A toilet wax ring is another name for this sort of seal.

The wax ring is wrapped around the aperture of the closet flange before the toilet is dropped into it, forming a seal between the toilet's base and the flange.

The wax ring is intended to compress and form a watertight barrier, preventing water and smells from escaping from the toilet's base. Other sealing techniques, such as plumber's putty or adhesive caulk, are not normally suggested since they may not offer a stable and long-lasting seal.
