A 120 watt light-bulb is a 0.120 kilowatt light bulb.
In one hour, it uses 0.120 kilowatt-hour of energy.
If electrical energy costs $0.20 per kilowatt hour, then that light bulb costs
(0.120 kilowatt-hour / hour) x (0.20 dollar / kilowatt-hour) =
(0.120 x $0.20 / hour) =
$0.024 / hour = <span>2.4¢ per hour </span>
Answer:
5.7
Step-by-step explanation:
sine cosine tangent
soh cah toa
sine = opposite/hypotenuse
so sin(35)= x/10
you can multiply 10 to both sides to get rid of the 10 denominator on the right leaving you with 10sin(35)=x
be sure your calculator is in degrees.
put that into a calculator leaving you with 5.7
