How much does it cost to run a computer for 50 hours in a week if the monitor runs on 140 watts and the tower runs on 260 watts and the electric company charges 11.2 cents per kilowatt-hour?

Total cost will be 224 cents

Step-by-step explanation:

We have given that total time t = 50 hour

It is given that monitor ruins at 140 watts

So P = 140 watt

We know that energy = power × time

So energy required for monitor run = 140×50 = 7000 watt hour = 7 kWh

Now tower runs at a power of 260 watts

So power P = 260 watt

So energy required for tower run = 260×50 = 13 kWh

Total energy required = 13 +7 =20 kWh

It is given that company charges 11.2 cents per kilowatt hour  

So total cost = 12×11.2 = 224 cents

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2
