Answer:
Therefore the width is 25 feet for getting maximum area.
The maximum area of the rectangle is 625 square feet.
Therefore the range is 0≤A≤625.
Step-by-step explanation:
Given function is
A = - x²+50x
We know that ,
If y = ax²+bx+c
For the maximum 
Here a = -1 , b= 50 and c=0
Therefore the width 
Therefore the width is 25 feet for getting maximum area.
The maximum area =[ -(25)²+50.25] square feet
= 625 square feet
The area can not be negative and maximum area is 625 square feet.
Therefore the range is 0≤A≤625.
Step-by-step explanation:
Option D is the correct answer because we will cross multiply
4/6 = 9/x
4x = 54
X = 27/2
Answer: Our variable be z for fair admission and our required linear equation will be

Explanation:
Since we have given that
Cost per ticket for the rides =$1.50
Total amount she spent = $48.75
Let the total cost be y
Let the number of ride tickets be x
<u>a) Define your variable:</u>
Let the amount spent on fair admission be z
<u>b) Write a linear equation that can be used to determine the cost for ride tickets and fair admission:</u>
Our required equation will be

Here, number of ride tickets = 20
So,

So, the cost for fair admission = $18.75
