For this case we can make use of the Pythagorean theorem.
 We have then:
 (root (117)) ^ 2 = x ^ 2 + 6 ^ 2
 Clearing x we have:
 x ^ 2 = (root (117)) ^ 2 - 6 ^ 2
 Rewriting:
 x = root (117-36)
 x = root (81)
 x = 9
 Answer:
 The value of x is given by:
 x = 9 cm
        
             
        
        
        
Answer:
952 cubic feet
Step-by-step explanation:
The diameter is 21, so the radius is 10.5. The area of a circle is πr^2, so 10.5^2π, or 110.25π. The pool is filled 9 inches from the top, so it is 3.5 feet - 9 inches high, 9 inches is 0.75 feet, so 2.75 feet filled. Now multiply 110.25π by 2.75 to get 303.1875π and then 952.4916, closer to 952 cubic feet.

Answer:
8
Step-by-step explanation:
3 - (-5) 
This can be rewitten to 
3 + 5
Why? 
2 negatives cancel each other out to make a positive, therefore:
3 + 5 = 8 or 3 - (-5) = 8
 
        
                    
             
        
        
        
Answer:
-458
Step-by-step explanation:
-1.5(4 - r) = -12 - 6 -446
-6 + r = -464
r = -458
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The time  in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this  equation.
t = va
We need to find the expression for d in terms of t and a.
As velocity = distance/time

So, the distance d is 
.
