What number is 30% of 20?<br><br><br>(will give Brainliest)
kirill [66]

In order to get the answer you will have to divide 30 by 100 then divide the number you get from that by 20 to receive your answer.

20/x=100/30

(20/x)*x=(100/30)*x      

20=3.33333333333*x      

(3.33333333333) to get x

20/3.33333333333=6

=6

Therefore your answer is "6."

Hope this helps

Answer:

3262.9 cm^3

Step-by-step explanation:

Formula =

\frac{4}{3}  \times \pi r ^{3}

Pi = 3.145

So,

\frac{4}{3}  \times 3.145 \times 9.2 ^{3}  \\   =  3262.183595 \\  = 3262.9 cm^{3}

Here you go

Identify all of the root(s) of g(x) = (x2 + 3x - 4)(x2 - 4x + 29)
vichka [17]

Answer:

x=-4,1,2+5i,2-5i

Step-by-step explanation:

Given is an algebraic expression g(x) as product of two functions.

Hence solutions will be the combined solutions of two quadratic products

g(x) = (x^2 + 3x - 4)(x^2 - 4x + 29)\\

I expression can be factorised as

(x+4)(x-1)

Hence one set of solutions are

x=-4,1

Next quadratic we cannot factorize

and hence use formulae

x=\frac{4+/-\sqrt{16-116} }{2} =2+5i, 2-5i
