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:
The formula for the circumference of a circle is C = 2πr, where r is the radius and C is the circumference. The equation solved for r is r =c/2π .

Answer:
radius ≈ 17.0 units
Step-by-step explanation:
The radius is the distance from the centre of the circle to a point on it.
Calculate the radius r using the distance formula
r = 
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (7, 12)
r = 
= 
= 
= 
≈ 17.0 ( to the nearest tenth )
