In the year 2000, the US census showed that 9.1% of those over 75 had not married so the percentage is relatively low and from 75-84 yrs old, about 50% were still married, 40% were widowed and 5.4 % were divorced.
        
             
        
        
        
Answer:
A lot of information is missing, so I looked for similar questions:
- 1,064 yd of fencing is available
since 1,064 is the perimeter and we have a rectangle, we can write the perimeter equation as: 2L + 2W = 1,064
area = L · W
2W = 1,064 - 2L
W = 532 - L
now we replace in the area equation:
area = (532 - L) · L = -W² + 532W (quadratic equation format)
the value of L as our X coordinate:
L = 532 / 2 = 266
W = 532 - 266 = 266
area = -(266)² + (532 x 266) = -70,756 + 141,512 = 70,756 sq yards
or
area = 266 · 266 = 70,756 sq yards
When you have a rectangle, the largest possible area is a square, where both sides have the same length. 
 
        
             
        
        
        
Answer:
This concept is called the opportunity cost. 
Explanation:
The opportunity cost of any economic decision is the cost of giving up or sacrificing its alternative. We are aware that resources are limited and have alternative uses. We have to use these resources to satisfy unlimited wants and needs.  
If we use resources for one purpose it cannot be used for another. So we have to make a decision on how to spend the resources, on which alternative use. If we select one alternative, we need to give up another. The cost incurred on sacrificing or giving up the other alternative is the opportunity cost of using the resource for the first alternative.
