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
There are 10 portions to the circle, and 7 of the 10 are shaded. 7/10 is 70%
Is that supposed to be x squared, or x times 2 in the beginning of the first one?
Answer: 
, where x= width of the rectangle ( in inches).
Step-by-step explanation:
Let x= width of the rectangle ( in inches).
Then its length = 2x-7 ( in inches).
Area of rectangle = Length × width
= (2x-7) × (x)
= 2x × x -7 ×x
= 2x²-7x
The area of the rectangle is 72 square inches.
Hence, the equation that represents the given situation :
Answer:
7 square units
Step-by-step explanation:
As with many geometry problems, there are several ways you can work this.
Label the lower left and lower right vertices of the rectangle points W and E, respectively. You can subtract the areas of triangles WSR and EQR from the area of trapezoid WSQE to find the area of triangle QRS.
The applicable formulas are ...
area of a trapezoid: A = (1/2)(b1 +b2)h
area of a triangle: A = (1/2)bh
So, our areas are ...
AQRS = AWSQE - AWSR - AEQR
= (1/2)(WS +EQ)WE -(1/2)(WS)(WR) -(1/2)(EQ)(ER)
Factoring out 1/2, we have ...
= (1/2)((2+5)·4 -2·2 -5·2)
= (1/2)(28 -4 -10) = 7 . . . . square units
