Answer:
The percentage change from July to November is 67.27 %
Step-by-step explanation:
Given as :
The number of tourists at the beach per weekend in the month of July = 
= 55,000
The number of tourists at the beach per weekend in the month of November = 
= 18,000
Let the percentage change from July to November = A %
Or, % decrease change = 
× 100
So , A % = ![\dfrac{\tetxtrm [tex]x_2](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctetxtrm%20%5Btex%5Dx_2)
- \textrm }{\textrm }[/tex] × 100
or, A % = 
× 100
Or, A % = 
× 100
Or, A = 67.27 %
So percentage change between two months = 67.27 %
Hence The percentage change from July to November is 67.27 % Answer
The length and width of the rug is 20 and 11 feet respectively
The given parameters;
dimension of the room = 19 ft by 28 ft
maximum area of rug she can afford = 220 ft²
For a uniform stripe of floor around the rug, then suppose the uniform excess length of the floor to removed from each dimension = y
(28-2x)(19-2x)=220
532-94x+4x^2=220
4x^2-94x+312=0
x=39/2,4
For x=39/2, dimensions are negative.
The uniform dimension of the floor to be covered by the maximum area of rug she can afford = (28 - 4×2) and (19 -2×4 ) = 20 and 11
Thus, the dimensions of the rug should be 20 feet and 11 feet
