6.50
Step-by-step explanation:
15.75-9.25=6.5
250/360 = x/60
x = 41.7 cm
This is because when the whole circle is 250 cm (angle is 360 degrees), 60 degrees means that the arc is 41.7 cm.

80 W divided by 1000 (to convert to kW) = 0.08 kW
The total cost can be calculated by multiplying wattage by time by electricity cost. Note how the units will cancel out, given that 2 weeks is equal to 14 days.
(0.08 kW)(0.5 h/day)(14 days) = 0.56 kWh
Multiply by the cost: ($0.08/kWh)(0.56 kWh) = $0.0448
So the closest answer is the first choice.
