Answer:

Step-by-step explanation:

$2018 \times (|\frac{1}{2017} - \frac{1}{2016} | + |\frac{1}{2018} - \frac{1}{2017}| - |\frac{1}{2018} - \frac{1}{2016}|)$

1/2017 is smaller than 1/2016. 1/2018 is smaller than 1/2017. And 1/2018 is smaller than 1/2016. So we can rewrite this as:

$2018 \times ((\frac{1}{2016} - \frac{1}{2017} ) + (\frac{1}{2017} - \frac{1}{2018}) - (\frac{1}{2016} - \frac{1}{2018}))$

Distribute:

$2018 \times (\frac{1}{2016} - \frac{1}{2017} + \frac{1}{2017} - \frac{1}{2018} - \frac{1}{2016} + \frac{1}{2018})$

Simplify:

$2018 \times (0)$

$0$

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.

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes,and 20 pages in 30 minutes. Is this a proportional relatio

maria [59]

Answer:

y = 2/3x

Step-by-step explanation:

Reading rate is y pages per x minutes and proportional relationship formula is:

y = kx

The coefficient is:

k = y/x

Let's verify if the given numbers fit into the same relationship:

12/18 = 2/3
8/12 = 2/3
20/30 = 2/3

We confirm all same and it means k = 2/3

Required equation is:

y = 2/3x

This represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages
