Let h equal the number of hours the electrician works.
We can write the equation like this:
90h + 60 = 600
Solve for h.
90h + 60 = 600
~Subtract 60 to both sides
90h + 60 - 60 = 600 - 60
~Simplify
90h = 540
~Divide 90 to both sides
90h/90 = 540/90
~Simplify
h = 6
Therefore, the electrician work for 6 hours.
The correct answer is Option 1.
Best of Luck!
The correct option is 4. PSU.
The hardware part that would be checked next is PSU.
<h3>What is Power Supply Unit PSU?</h3>
An internal piece of IT hardware is known as a power supply unit (PSU). Despite their name, power conversion devices, or PSUs, do not really supply power to systems.
Some key features of PSU are-
- A power supply specifically transforms alternating high voltage current (AC) to direct current (DC) and regulates the DC output voltage to the precise tolerances needed for contemporary computing components.
- There is, however, a PSU substitute that may be utilized in specific circumstances.
- Electrical power can be transported inside network cables using Power over Ethernet (PoE), freeing the device from being bound to an outlet.
- Because PoE can deliver wireless access points wherever it is most convenient and uses less room for wiring, it is perfect for systems that need greater flexibility.
