Question

3. Write all the possible pairs of integers that give a product of -50?​

Answer 1

Answer:

Given that, It would take 140 minutes to fill a swimming pool using the water from four taps.

Now, we have to find the time taken to fill a swimming pool if two taps are used.

We know, less number of taps are used to fill a swimming pool, more time is taken to fill.

So, it means, number of taps to fill a swimming pool is inverse variation with time taken to fill a swimming pool.

Let assume that time taken by 2 taps to fill a swimming pool is x minutes.

So,

\begin{gathered}\color{blue}\begin{array}{|c|c|c|c} \hline \rm Number \: of \: taps&\rm 4&\rm 2 \\ \\ \hline\rm Time \: taken \: (in \: minutes)&\rm 140&\rm x \\ \\ \hline \end{array} \\\end{gathered}
