The area of the rect. is 100 ft times 64 ft, or 6400 ft^2.
Let's list factors of 6400: 64,100
64= 2^6
100= 2^2*5^2
Here we see that 2 appears 8 times as a factor, and 5 appears 2 times:
6400 = 2^6 * 10^2 = 2^8*5^2
 
        
             
        
        
        
We are given two points: (-1, -1) and (1, -4). Slope is calculated as the change in y over the change in x, or rise over run. 
The change in y is the difference of the two y coordinates (it doesn't matter the order): -1 - (-4) = 3
The change in x is the difference of the two x coordinates (this order depends on the order that you subtracted the y coordinates; they must be the same order): -1 - 1 = -2.
So, the slope is 3/-2

Answer:
New Cost of item is 
Step-by-step explanation:
Given:
Original Cost of item = 
Item was marked down by 
To Calculate Cost after  marked  down we need to multiply original cost by 50 and then divide by hundred.
 marked  down we need to multiply original cost by 50 and then divide by hundred.
Cost after  marked down = 
Now New cost of the item is calculated by Subtracting Cost after  marked down by Original Cost of item.
 marked down by Original Cost of item.
New cost of the item =
