It takes four minutes to fill a bathtub if the hot and cold water taps are both on and the stopper is in. It takes six minutes t
bekas [8.4K]

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

\frac{1}{4} - \frac{1}{6} = \frac{3}{12} - \frac{2}{12} = \frac{1}{12}tub

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

Which is the best estimate for the average rate of change for the quadratic function graph on the interval 0 ≤ x ≤ 4?
den301095 [7]
ANSWER

A) -1

EXPLANATION

The average rate of change of the given quadratic function on the interval 0 ≤ x ≤4 is the slope of the secant line connecting the points (0,f(0)) and (4,f(4)).

That is the average rate of change is:

= \frac{f(4) - f(0)}{4 - 0}

From the graph, f(0) is 0 and f(4) is -4.

We plug in these values to obtain;

= \frac{ - 4 - 0}{4 - 0}

This simplifies to;

= \frac{ - 4}{4}

= - 1

Hence the average rate of change for the given quadratic function whose graph is shown on 0≤x≤4 is -1

Answer:

I believe you are right.

Step-by-step explanation:

All sides seem to be of similar length. The values you put in would make the sides equal so I would go with that one.

Which expression shows how 6 • 45 can be rewritten using the distributive property?
tatuchka [14]
6*45=270 is the first step you should do to get the answer you are looking for. The next thing I would do is go to all the answers to see which one comes out the same way. The first one comes to be 246, the next one is 54, the next is 270 and the last one is 220. 6*40+6*5 is the correct answer.
