Well a and b both would be.
Answer:
simple
Step-by-step explanation:
The radius of the wheel can be solved from its given speed and RPM.
Converting km/h to m/min
speed = 66 km / h = 66000 m / 60 min
speed = 1100 m / min
Converting one revolution to meters
1100 m / min = 500 revolution / min ... (given)
500 revolutions = 1100 m
1 revolution = 2.2 m
Solving for the radius of the wheels in meters
1 revolution = 2.2 m
2 * pi * radius = 2.2 m
radius = 2.2 m / 2 * pi
radius = 1.1 m / pi
radius = 0.3501 m
83 FT Because if you divide 786 by 12 (Which is how many inches are in a foot) you will get 65.5 ft.
Let C₀ be current consumption. Then consumption (C) after t years is:
<span>C(t) = C₀ * (1 + 0.1)^t </span>
<span>C(t) = C₀ * (1.1)^t </span>
<span>After 10 years, consumption will be: </span>
<span>C(10) = C₀*(1.1)^10 </span>
<span>C(10) = 2.5937424601 C₀ </span>
<span>Total percentage increase after 10 years: </span>
<span>(2.5937424601 C₀ - C₀) / C₀ = 1.5937424601 C₀ / C₀ = 1.5937424601 = 159.37% </span>
<span>Utility company will have to increase generating capacity by 159.37%</span>
