What is .16 repeating as a simplified fraction?

Readme [11.4K]

I'm assuming this is 0.1666666...

Which in that case is 1/6.

(Just from memory)

To do 0.161616161616...

First, assign 0.161616... a variable, say it's x.

Now say 100x, what is it.

16.1616161616...

Now subtract x from 100x.

16.161616161616... - 0.16161616...

Or, 99x

99x = 16 in this case right now

Divide both sides by 99

x = 16/99

So it really depends what's repeating, it's either 1/6 or 16/99.

Answer:

$a.\ \ \ A=684\ m^2$

$b.\ \ \ A=130.2 \ km^2$

Step-by-step explanation:

a. Area is calculated by summing the areas of the prism's individual surfaces.

#First, calculate the areas of the right-angled surfaces:

$Area=2(\frac{1}{2}bh), b=9, h=12\\\\=2\times \frac{1}{2}\times 9\times 12\\\\=108\ m^2$

#We then find the areas of the rectangular surfaces:

$A=lw\\\\=15\times 16+9\times 16+16\times 12\\\\=576\ m^2$

#We sum the areas to find the total surface areas:

$A=\sum{Areas_i}\\\\=108+576\\\\=684\ m^2$

Hence, the prism's surface area is $684\ m^2$

b.Area is calculated by summing the areas of the prism's individual surfaces.

#First, calculate the areas of the right-angled surfaces:

$A=2\times \frac{1}{2}bh,\ b=12, h=4.1\\\\=2\times 0.5\times 12\times 4.1\\\\=49.2 \ km^2$

#We then find the areas of the rectangular surfaces:

$A=lw\\\\=5\times 3+3\times 10+12\times 3\\\\=81\ km^2$

#We sum the areas to find the total surface areas:

$A=A_r+A_t\\\\=81+49.2\\\\=130.2 \ km^2$

Hence, the prism's surface area is $130.2 \ km^2$
