1 Acre = 43560 square feet
1 Ton = 2000 pounds
320 Acres = 320 * 43560 square feet = 13939200 = <span>1393.92 * 10,000

Answer: there were 19 birds at the shelter on Wednesday
Step-by-step explanation:
Let x represent number of beds at the shelter on Wednesday.
Let y represent the number of cats at the shelter on Wednesday.
Nicole found a record showing that there were a total of 40 birds and cats on Wednesday. This means that
x + y = 40
The animal shelter spends $5.50 per day to care for each bird and $8.50 per day to care for each cat. Nicole noticed that the shelter spent $283.00 caring for birds and cats on Wednesday. This means that
5.5x + 8.5y = 283 - - - - - - - - - - -1
Substituting x = 40 - y into equation 1, it becomes
5.5(40 - y) + 8.5y = 283
220 - 5.5y + 8.5y = 283
- 5.5y + 8.5y = 283 - 220
3y = 63
y = 63/3 = 21
x = 40 - y
x = 40 - 21 = 19
70*35 / 100 + 30*25 / 100
2450 /100 + 750/100
24.50 + 7.50 = 32
So, your answer is $32

Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
