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.

Please help, I'm struggling with this so much! (8n^5-3n^4-56n^2+13n)÷(8n-3)
OlgaM077 [116]

Automatically, we can factor an n out of the dividend, as each term shares this factor.

The new dividend is 8n^4 - 3n^3 - 56n + 13

After applying algebraic long division, which is included in the screenshot below, the quotient is equal to n(n^3 - 7 + (8/8n - 3))

What are the soltions to the innequality -7x+14 is grater than -3x-6
hichkok12 [17]

-7x+14>-3x-6

Add 3x to both sides

-7x+14+3x>-3x-6+3x

-4x+14>-6

Subtract 14 from both sides

-4x+14-14>-6-14

-4x>-20

Divide both sides by -4

-4x/4>-20/-4

x<5


I hope that's help , please let me know !
