Sales tax = 6% or 6/100. 
assuming tax is added onto the item:
total cost function f(x) = price + tax
however, assuming the cost price = sales price  - tax,  then:
f(x) = sales price - tax 
This is not really a business or accounting forum, its a maths forum, so you need to be clearer about business or accounting terms such as total cost, selling price, selling cost.

w represents width

4w represents length

d represents diagonal

w2 + (4w)2 = d2

w2 + 16w2 = d2

17w2 = d2

±w√17 = d

 

The diagonal is the width times √17.

What is the missing numerator of 4/9= ?/81
yKpoI14uk [10]
To solve this question, first cross multiply
Let ? = x

4/9 = x/81

4(81) = 9(x)

Simplify.

81 x 4 = 324

324 = 9x

Isolate the x, divide 9 from both sides

324/9 = 9x/9

x = 324/9

x = 36


4/9 = 36/81

36 is your answer

hope this helps!

charle [14.2K]

Answer:

16 bags

Step-by-step explanation:

To find this, we <em>divide 2 over 1/8</em>, to see how many <em>units of 1/8 fits into that of 2</em>.

\frac{2}{\frac{1}{8} } can be rewritten as <em>2*8</em>. 2*8 = 16 bags.
