If you have 30 students in your class and you want to know how many groups of 5 people you could make.

Answer:

Well, it is complicated because I've never studied that in math. I searched up the definitions of both in math and they're very similar. Permutation is a one of many possible variations and can change. A combination is the process of joining to things to be one. So if I had to choose I think I'd go with permutation since it isn't asking you to list all the ways you can make groups out of the number 30.

Answer:

w = 1.6

Step-by-step explanation:

Given w varies inversely as $\sqrt{x}$ then the equation relating them is

w = $\frac{k}{\sqrt{x} }$ ← k is the constant of variation

To find k use the condition when x = 4, w = 4

k = w $\sqrt{x}$ = 4 × $\sqrt{4}$ = 4 × 2 = 8

w = $\frac{8}{\sqrt{x} }$ ← equation of variation

When x = 25, then

w = $\frac{8}{\sqrt{25} }$ = $\frac{8}{5}$ = 1.6

Hi,

To find the volume of cylinder this formula is required.

$v = \pi {r}^{2} h$

To get radius you need to divide diameter with 2 like this.

$80 \div 2 = 40$

Now just put your values into formula.

$v = \pi {40}^{2} \times 130 \\ v =653451.27$

You will need 653451.27 cubic centimetres of concrete.

Hope this helps.
