What is 8x1/6 plz help

alekssr [168]

This is a very simple math question and it's unfortunate that most rely on other's answer to just get over it and aren't willing to learn.

Multiply:
8 x 1/6 = 8/6
Now change 8/6 into a mixed number and simplify; can you try doing that?

What is 0.3111111111111111 as a fraction?

Citrus2011 [14]

$\sf~N=0.3\overline{1}$

There is only one repeating number, so we multiply both sides by $\sf10^1$ or $\sf10$ .

$\sf10N=3.\overline{1}$

Now subtract the original number we had to both sides, which is the same as $\sf~1N$ or $\sf~N$

So we have:

$\sf9N=2.8$

Divide 9 to both sides:

$\sf~N=\dfrac{2.8}{9}$

Multiply the fraction by 10 to get rid of the decimal in the numerator.

$\sf~N=\dfrac{28}{90}$

Simplify the fraction by dividing the numerator and denominator by 2:

$\sf~N=\boxed{\sf\dfrac{14}{45}}$

A piece of wire 25 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral tria

fomenos

Answer:

Wire used for square is 7.55 m.

Step-by-step explanation:

Let the length of wire cut for square be 'x'.

Given:

Total length of the wire = 25 m

Length of wire for square = 'x'

Length of wire for equilateral triangle = $25-x$

Now, area of square (a) = $x^2$

Area of equilateral triangle (e) is given as:

$e=\frac{\sqrt3}{4}(25-x)^2$

Now, total area (A) is given as:

$A=a+e\\\\A=x^2+\frac{\sqrt3}{4}(25-x)^2$

Now, in order to maximize 'A', the derivative of area with respect to 'x' must be 0.

∴ $\frac{dA}{dx}=0$

$\frac{d}{dx}(x^2+\frac{\sqrt3}{4}(25-x)^2)=0\\\\2x-\frac{\sqrt3}{2}(25-x)=0\\\\2x+\frac{x\sqrt3}{2}=\frac{25\sqrt3}{2}\\\\x(2+\frac{\sqrt3}{2})=\frac{25\sqrt3}{2}\\\\x(4+\sqrt3)=25\sqrt3\\\\x=\frac{25\sqrt3}{4+\sqrt3}=7.55\ m$

Therefore, the length of the wire that is cut for square should be 7.55 m for maximum area.
