For this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?

What is the conversion of 6 times per minute to seconds?
The consumption rate of electricity, in kW/h has increased, on average, at 4.5% per year. If it continues to increase at this rate indefinitely, find the number of years before the electric companies will need to double their generating capacity The electric company will need to double their generating capacity about every years. (Do not round until the final answer. Then round to the nearest tenth as needed)
