An art museum uses a dehumidifier to remove moisture from the air at a constant rate to prevent damage to the paintings. The graph shows the amount of water it removes from the
air over time. How much water does the dehumidifier remove in 8.5 hours?

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
