Manuel constructs a scale model of a building with a rectangular base. Her model is 3 inches in length and 1 inch in width. The scale on the model
is 1 inch = 43 feet. What is the actual area, in square feet, of the base of
the building? (draw it out to help answer the question)

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.
