The probability of flipping a coin to get heads is 1/2 or 50%. If you multiply this, by how many times you flip it, or 1/2 * 1/2 * 1/2, then you get 1/8 or 12.5% chance that she will get heads 3 times in a row

Whats the area of the lawn in this shape

Licemer1 [7]

Answer:

208 ft

Step-by-step explanation:

in order to do this we need to find the area of the retangle:

(l x w) 14x20= 280ft

then the area of the rectangle:

a^2 + b^2 = c^2 ( hypotenus lenght )

c= 8.5

now we can plug in to find the area of the triangle, which is 12 (11.99)

then the area of the trapezium= 60

finally we can find the answer

280 - (60+12)= 208 ft :)
