Answer:

1) 25+7(n-1)

When the above 'n'(hours) is substituted on the equation, it equals up to the right cost.

2) Given that n represents the no.of bikes, you just plug it in to the equation below.

250+39(n-1)

= 250+39(20-1)

= 250+39*19

= 250+741

A cylindrical well is 15 meters deep and has a diameter of 1.6 meters. Approximately how many cubic meters of soil were dug out

Lisa [10]

We can dig out the soil from the well equal to volume of well.

Height(h) of well is = 15 meters.

Diameter = 1.6 meters.

So radius(r) = $\frac{1.6}{2} = 0.8$ meter.

As well in cylindrical shapes.

So volume of well = $\pi r^2h$
                               = $\pi * (0.8)^2 * 15$
                                $= 9.6 * \pi$
In general $\pi = 3.14$

So volume of well is = $9.6 * 3.14$
   $= 30.144$ cubic meter.

So we can dig out 30.144 cubic meter soil from well.
