-6+3-3(-18)
Okay. 
Work from left to right. 
-6 plus 3 equals -3. 
(Think of it as in a number line, from the spot of -6, move right three units. This will give you -3. Anyways..)
Now you have -3-3
The result is -6.
-6(-18)

Answer:
$81,000
Step-by-step explanation:
A = Final Payment = ?
P = Principal Amount = $30,000
r = Interest Rate = 8.5%
t = Time = 20 Years
A = P(1 + rt)
A = 30,000(1 + 0.085 x 20)
A = 30,000 + 51000
A = $81,000
Hence, Steph will pay $81,000 altogether.
 
        
             
        
        
        
So volue of a cone=area of circle base times heigt times 1/3
height=4
area of base=pi times r^2
area of abse=aprox 3.14 times 3.2^2=32.1536
32.1536 times 4 times 1/3=32.1536 times 4/3=42.87 the amount of sand is 42.9 ft^3
