Answer:

\frac{19}{8} hours is closest to 2 hours.

Step-by-step explanation:

We have been given three numbers and we need to decide which of the three numbers is closest to 2.

In order to decide that, we will convert each of the given numbers into decimals and then we will compare.

\frac{11}{4} =2.750\\\frac{19}{8}=2.375\\2.6=2.600

Upon comparing 2.750, 2.375 and 2.600 we know that 2.375 is closest to 2. Therefore, out of the given three numbers, \frac{19}{8} is closest to 2.

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.

I need the answer for this exact question
denis23 [38]

Answer:

y=\frac{7}{2}x-20

Step-by-step explanation:

Let the equation of the line be y-y_1=m(x-x_1) where, 'm' is its slope and (x_1,y_1) is a point on it.

Given:

The equation of a known line is:

y=-\frac{2}{7}x+9

A point on the unknown line is:

(x_1,y_1)=(4,-6)

Both the lines are perpendicular to each other.

Now, the slope of the known line is given by the coefficient of 'x'. Therefore, the slope of the known line is m_1=-\frac{2}{7}

When two lines are perpendicular, the product of their slopes is equal to -1.

Therefore,

m\cdot m_1=-1\\m=-\frac{1}{m_1}\\m=-\frac{1}{\frac{-2}{7} }=\frac{7}{2}

Therefore, the equation of the unknown line is determined by plugging in all the given values. This gives,

y-(-6))=\frac{7}{2}(x-4)\\y+6=\frac{7}{2}x-14\\y=\frac{7}{2}x-14-6\\\\y=\frac{7}{2}x-20

The equation of a line perpendicular to the given line and passing through (4, -6) is y=\frac{7}{2}x-20.
