Answer:
32  
 
Step-by-step explanation:
Given: 
- The slant length 10 units
- A right square pyramid with base edges of length 8  
Now we use  Pythagoras to get the slant height in the middle of each triangle: 
 =
 =  =
 =  units
  units 
One again, you can use Pythagoras again to get the perpendicular height of the entire pyramid.
 =
 =  = 6 units.
 = 6 units. 
Because slant edges of length 10 units each is cut by a plane that is parallel to its base and 3 units above its base. So we have the other dementions of the small right square pyramid:
- The height 3 units
- A right square pyramid with base edges of length 4  
So the volume of it is: 
V  = 1/3 *3* 4 
 
= 32  
 
 
        
             
        
        
        
Answer:

⇒  [Factorized form]
        [Factorized form]
Step-by-step explanation:
Given expression:

We need to make  the subject.
 the subject.
In order to do that we need to solve the expression for  in terms of
 in terms of  and
 and 
We have,

Subtracting both sides by 


Taking square root both sides in order to remove square of 


The difference of squares can be factorized and written  as:
 [difference of squares
    [difference of squares  ]
 ]
 
        
             
        
        
        
Answer: 158
Step-by-step explanation:
Okay so the total is 9 5/10.
Each party goer needs 6/10 
So 95/10 / 6/0=. 95/10x10/6
=950/6 = 158.
 
        
             
        
        
        
Subtracting a negative number is the same as adding a positive number
assume your number is n
n - (-10) = 6 
n + 10 = 6 
subtract 10 from both sides
        
                    
             
        
        
        
Answer:
25GB was used that month 
Step-by-step explanation:
Here, we want to calculate the GB used for the month.
Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.
The extra charges is thus $75.99 - $59.99 = $20
Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5
So the total GB for that month is 20 + 5 = 25GB
