Answer:

  -2 11/35

Step-by-step explanation:

Put the numbers where the variables are and do the arithmetic.

  \left(\dfrac{x^2}{x}-3\right)\div10\cdot z=\left(\dfrac{(-6)^2}{1.2}-3\right)\div10\cdot\left(-\dfrac{6}{7}\right)\\\\=\left(\dfrac{36}{1.2}-3\right)\div10\cdot\left(-\dfrac{6}{7}\right)=(30-3)\div10\cdot\left(-\dfrac{6}{7}\right)\\\\=\dfrac{27}{10}\cdot\left(-\dfrac{6}{7}\right)=-\dfrac{27\cdot6}{10\cdot7}=-\dfrac{27\cdot3}{5\cdot7}=\boxed{-\dfrac{81}{35}=-2\dfrac{11}{35}}

__

It is important to note here that the order of operations requires that the only value being divided by is 10, not 10z. The division by 10 occurs before the multiplication by z.

The smaller cone is replaced with another cone of equal radii, but a height twice as big.
Bess [88]
Let's make this simple. Let's have the small cone have a radius 1 and the height 1. This would make the bigger cone have a radius of 1 and the height of 2.

With this information, lets get the volume of both cones. The formula is this:

V =  \dfrac{(\pi r^2 h)}{3}

Plug in numbers:
Small cone: V =  \dfrac{(\pi 1^2 \times 1)}{3}
Big cone: V =  \dfrac{(\pi 1^2 \times 2)}{3}

The small cone has a volume of \dfrac{\pi}{3}
The big cone has a volume of \dfrac{2 \pi}{3}

Now, you want to find how many small cones you need to have the same total volume of the big cone.

\dfrac{2\pi}{3} -  \dfrac{\pi}{3} =  \dfrac{\pi}{3} 


You have the difference of pi over 3 comparing the big cone to the small one. You realize that the small cone has the same volume of that. Therefore, you need 2 small cones to have the same total volume as the larger cone
