The value of 1 penny, 1 nickel, and 1 dime is $0.16. The total value of the coins is 8 times that, so the bank contains 8 of each coin.
The area of any triangle = (1/2) x (length of the base) x (height)
2.5 centimeters = 0.025 meter
The area of the sail is (3.75) = (0.5) x (0.025) x (height)
Multiply each side by 2 : (7.5) = (0.025) x (height)
Divide each side by 0.025 : (7.5)/(0.025) = height =<em> 300 meters</em>
The situation is stupid, but the math is bullet-proof.
Multiply 2/3 by 84 which is 56.
The distance between the points is 5
