A company has determined that the number of items it sells varies inversely as the price of the item. If 20,000 items can be sol
mestny [16]
Let N be the number of items sold and p the price. 
Since the variation is inverse, then the relation between N and p is:
N=k\dfrac{1}{p}
For N=20000 and p = $9.5, we get the formula:
 20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000
If p = 8.75, then the number of items sold can be computed using the formula:
N= 190000\dfrac{1}{8.75}=21714 \text{ total items}

Answer:

Area of parallelogram is 150 square ft

Step-by-step explanation:

Given the parallelogram in the figure whose height is 10 ft and base length is 15 ft.

Area of parallelogram is base \times height

                                       = 15\times 10ft^2

                                       = 150 square ft

now we have to decompose this parallelogram into rectangles and triangles and then to determine the shape.

The given parallelogram KLMN can be decomposed into 2 triangles and one rectangle.

2 right angled triangles KPL and NOM by construction

KL^{2}=KP^{2}+PL^{2}=10^{2}+2^{2}                                          =100+4=104

⇒ KL=\sqrt104=10.2 ft=MN         (∵ KLMN is a parallelogram)

Hence, dimension of triangles are 10 ft, 2 ft and 10.2 ft

Now rectangle KPON with dimension 15 ft and 10 ft because KP and NO are perpendiculars on LM.
