I believe the answer is 23.52 because if u add 19.60 to 20% thats what u get
Answer:
See solutions for detail.
Step-by-step explanation:
a.
is the instantaneous rate of change of volume given with respect to time, t.
The volume's rate of change is written as a function of time.
-
is the rate of change in the height of water in the tank with respect to time, t.
b.
is the only constant. Water flows into the constant at a constant rate, say
per minute.
c.
is positive. Volume water in the take is increasing from time to time.
-The volume at time t=1 is greater than the volume at t=0, hence, it's a positive rate of change.
d.
is a positive rate. The initial height of water in the tank is zero.
-The final height at time t is 0.25h. The height is increasing with time.
Hence, it is positive.
The three sides make a right triangle and you know the base (90) and the height (70)
A = 1/2 bh or 1/2 x (70)x (90)= 3150 ft²

The given angles forms linear pair, and we know the angles forming linear pair are supplementary,
Therefore,
Angle MHJ + Angle MHL = 180°
Let's solve :
Value of variable m = 10°

Your answer is A
hope this helped
to get this answer you multiply 475 by 1.75% and then you get 8.31
