16.22 because two twenty dollar Bill's equals 40 then subtract 23.78 which equals 16.22
Answer:
11:50
Step-by-step explanation:
Go back 40 min before 12:20
The sum would end us as: 2.33333333
According to the Pythagorean theorem, the square of the hypotenuse (the longest side) of a right-angled triangle equals to the sum of the squares of the other two sides. In this case, the ladder is the hypotenuse, which equals to the distance between the bottom of the ladder and the tree + the distance we want to find (x):
5² + x² = 13²
25 + x² = 169
x² = 144
x = √144 = 12.
The distance between the ground and the top of the ladder is 12 ft.
