For example, 60%=0.60
For 0.17% = 0.0017
Answer:
12 minutes
Step-by-step explanation:
Since it takes 4 minutes to fill the bathtub with both taps on and stopper is in then for each minute the 2 taps can fill up to a quarter (1/4) of the tub:
Similarly, it takes 6 minutes to drain the tub with both taps off and the stopper is out. This means for each minute the stopper can drain one sixth (1/6) of the tub.
Therefore, when both taps are on and the stopper is out, then for each minutes, the amount of water remaining in the tub is the water flowing in minus the water draining out

So for each minute, one twelveth of the tub is filled, for the tub to be completely filled in, it would take 12 minutes

Answer:
<em>-1.031 m/s or </em>
Step-by-step explanation:
We take the length of the rope from the dock to the bow of the boat as y.
We take x be the horizontal distance from the dock to the boat.
We know that the rate of change of the rope length is
= -1 m/s
We need to find the rate of change of the horizontal distance from the dock to the boat =
= ?
for x = 4
Applying Pythagorean Theorem we have
.... equ 1
solving, where x = 4, we have



Differentiating equ 1 implicitly with respect to t, we have

substituting values of
x = 4
y = 
= -1
into the equation, we get

= <em>-1.031 m/s</em>
