7 identical taps can fill 3 identical tanks in 45 min. How long it will take 5 of the taps to fill one of the tanks?

21 minutes

Step-by-step explanation:

Given that:

7 identical taps fill 3 identical tanks in 45 minutes

Since the taps and tanks are identical :

Hence, the 7 taps can fill 1 tank in :

45 /3 = 15 minutes

Therefore, 1 tap will fill 1 tank in :

7 tap = 15 minutes

1 tap = (15 * 7) = 105 minutes

Hence, 5 taps will fill 1 tank in :

105 minutes / 5

= 21 minutes

is means division by fractions

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
