Scientists in a test lab are testing the hardness of a surface before constructing a building. calculations indicate that the entire structure would sinkby a certain amount for every additional floor that is added. if the maximum permissible limit for depression of the structure is 20 centimeters, howmany floors can be safely added to the building?

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
