4 is 80% of what number?

2 answers:

6 0

Your equation would be 4=80%x. Let X represent the number you are looking for.
First, you must change 80% in to a decimal because you cannot multiply a percent. 4=8x
Then, divide 4 by 8 to solve X.
Your answer is .5.
To check if your answer is correct, plug in .5 into the equation. 4=8×.5.

Rewrite, differentiate and simplify:<br> 3/(2x)^3

Llana [10]

$\frac{dy}{dx}$ = - $\frac{9}{8x^{4} }$

let y = $\frac{3}{(2x)^{3} }$ = $\frac{3}{8}$ $x^{-3}$

differentiate using the power rule

$\frac{d}{dx}$ ( $ax^{n}$ ) = na $x^{n-1}$

$\frac{dy}{dx}$ = - $\frac{9}{8}$ $x^{-4}$ = - $\frac{9}{8x^{4} }$

The area of circle Z is 64. What is the value of r? r = ____ft

andrezito [222]

Given the circle has a radius of 64, to get the value of the radius,r we shall proceed as follows.
Area=πr^2
Thus;
64=πr^2
64/π=r^2
r^2=20.3718
r=sqrt(20.3718)
r=4.5135
Therefore the length of radius,r=4.5135 units
