Irina-Kira [14]
Hey there!

For each of those combinations, there are an additional 7 options for an outfit. That means that there is a total of 105 options (7 × 15) available to choose from.

suter [353]
Since the Power is directly proportional to the velocity, their ratio \frac{P}{v^{3} } is constant.

<span>Therefore </span>\frac{500}{ 10^{3} } = \frac{x}{ 12^{3} } which is a proportion:

500 : 1000 = x : 1728

that can be easily solved:

x = (500×1728)/1000 = 864kW
