Answer:
25.65 square yards
Step-by-step explanation:
The area is 85.5 yd^2
He rents 3/10ths
Multiply the area  by the fractional part he rents
85.5 * 3/10
256.5/10
25.65 yd^2

because 4/6=2/3
2/3=6/9
so 4/6=6/9
 
        
             
        
        
        
Answer:
 b. average total cost = total cost/quantity of output
Step-by-step explanation: 
The marginal cost is the additional cost of producing one more unit of output and it can be calculated by taking the change in total cost and dividing it by the change in quantity, its formula is:
- <em>Marginal cost = change in total cost/ change in quantity</em>
The average total cost (sometimes referred to simply as average cost) is total cost divided by the quantity of output, its formula is:
- <u><em>Average total cost = total cost / quantity of output</em></u>
The total cost  is obtained adding together the fixed costs and the variable costs, its formula is: 
- <em>Total cost = fixed cost + variable cost</em>
The average variable cost is obtained when variable cost is divided by quantity of output, its formula is: 
- <em>Average variable = variable cost / quantity of output</em>

For any x in Real numbers, [x] is the greatest possible integer smaller than x, or equal to x if x is an integer.
According to this,
<span>[2.4] is the greatest integer , smaller than or equal to (so non greater) 2.4. This number is 2
similarly,  </span>[-2.4] is the greatest integer , smaller than or equal to (so non greater) -2.4. This number is -3.
Answer: 
A) <span>Because 2 is the greatest integer not greater than 2.4 and –3 is the greatest integer not greater than –2.4. </span>
