Cos(x) = 32/40 = 0.8 ⇒ x ≈ 37°
The drain pipe can drain (1/2) of the tank in 1 hour.
The fill pipe can fill (1/6) of the tank in 1 hour.
Working together, the pipes will drain the tank in (1/2) - (1/6) hours.
(1/2) - (1/6) = (3/6) -(1/6) = (2/6) or (1/3) of an hour.
So, working together, it will take 3 hours.

Answer:
is not a rectangle
Step-by-step explanation:
The midpoints of the diagonals are ...
AC midpoint = ((2, -2) +(11, 13))/2 = (13/2, 11/2)
BD midpoint = ((14, 10) +(-2, 1))/2 = (6, 11/2)
The midpoints of the diagonals are different, so this is not a rectangle or any sort of parallelogram.
A balance is used to measure mass.
