Answer:
In the next electricity bill the household will owe $40.
Explanation:
Given that a household uses 400 kilowatt-hours of energy in one month, and DWP charges $ 0.10 per kilowatt-hour, to determine how much will this household owe on their next bill, the following calculation must be performed:
400 x 0.10 = X
40 = X
Thus, in the next electricity bill the household will owe $40.
Black means 0
Brown means 1
Red means 2
Silver means the value is accurate within ±10%
_____________________________________
The first band is brown which means 1
So write down 1
Then write a decimal point to the right giving 1.
The second digit is black which means 0
So write 0 on the right giving: 1.0
The third band is red which means 2. The third band gives the power of 10 which is therefore 10². Multiply by this giving:
1.0x10²
This is best written as 100. So the resistance is 100 ohm
10% of 100ohms is 10ohms. So the resistance could be 10ohms lower than 100 or 10ohms higher than 100.
So the resisitance is between 90 ohms and 110 ohms.
So I'm guessing it's 100
