Answer:

Step-by-step explanation:
The answer would be 85.30 i had this question before
Answer:
21/25 = 84% 84% is the largest out of them all in a percentage number.
1/5/12 because,
3x4=12,4x2=8 witch would be 8/12 the 3x3=9+the 12=9/12. 9/12+8/12=1/5/12 so the path is 1/5/12.
If x is the distance the base of the ladder is from the wall, and y is the distance to top of the ladder is up the wall, then the Pythagorean theorem tells you
... x² + y² = 10²
Differentiating with respect to time, we have
... 2x·dx/dt + 2y·dy/dt = 0
... dy/dt = (-x/y)·dx/dt
We are given x = 6 ft and dx/dt = 3 ft/s. Using the first equation, we can find y as
... y = √(10² -6²) = 8
Then
... dy/dt =(-6/8)·(3 ft/s)
... dy/dt = -2.25 ft/s
The top of the ladder is sliding down the wall at -2.25 ft/s.
