  1. Convert all the powers from W to KW dividing by 1000.
  2. Convert all the times on minutes to hours dividing by 60.
  3. Then you can apply energy consumption formula Energy = Power*Time for any of the appliances. the results will be at KWh.
  4. Sum all the consumtions and you will have the total cost.

Rewrite the following condition to avoid a possible arithmetic exception:
dangina [55]

Answer:

if (x > 7 && Math.sqrt(x) < 3)

Explanation:

The previous condition checks if the square root of x is less than 3, but this would raise an error if x is a value equal to or less than 0.

So, the condition checks for the value of x before evaluating the square root after the AND operation to prevent an arithmetic exception.

Which installation changes from the old information system to the new one incrementally, starting with one or a few functional c
Wewaii [24]

Answer:

Phased installation

Explanation:

The name of this strategy is phased installation. Phased installation (or phased implementation) occurs when an existing system is replaced by a new one. However, unlike most implementations, this takes place in stages. This has several advantages. First, it allows you to test the system. If there is a problem with it, it is easier to revert back to the old strategy. Moreover, if employees need to adopt this new system, it allows them to get used to it slowly while still being able to access the previous one.
