Amedical researcher has two petri dishes containing viruses. dish a has a population density of 1.2 viruses per square millimeter. dish a has an area of about 2,826 square millimeters. if both petri dishes have the same population density, approximately how many viruses are in dish a?
a right triangle
half the diagonal is given as 7 yards, the full diagonal would be 7 x 2 = 14 yards.
the formula for the length of a side of a square using just the diagonal is:
side = √2(d/2)
side = √2 (14/2)
side = √2(7)
side = 9.9 yards.
the area of a square is s^2
area = 9.9^2
area = 98.01
area = 98.0 yards^2
the right option is a) 0.72%
we have given,
number of shares = $100
park stock per share = $52.89
total parks stock = 100×52.89 = $5289
since company paid annual dividends of $0.38 per share.
total annual dividend company paid = 100×0.38 =$38
total annual yield in % = = 0.718 % ≈0.72%
hence the right option is a) 0.72%
