Answer:
So you don't overspend.
Step-by-step explanation:
Lets say you bring $10 and everything at the store is half off the price is half of its original (huge savings) and you buy a toy that was $12 and now its $6, if you calculate your own saving you know you have $4 left to spend.
Hope this helps!

Total surface area of the square pyramid is 1476 cm².
Step-by-step explanation:
Total surface area of a pyramid = 12pl + B. Here p is perimeter of the base which is a square = 4 × side, l is the slant height and B is the area of the base = side²
Find perimeter of the base
⇒ p = 4 × side = 4 × 6 = 24 cm
Find the slant height of the prism. l² = height² + (side/2)² (Based on Pythagoras Theorem)
⇒ l² = 4² + (6/2)² = 16 + 9 = 25
⇒ l = √25 = 5 cm
Find the area of the base of the pyramid.
⇒ B = side² = 6² = 36 cm²
Calculate total surface area of the pyramid.
⇒ TSA = 12 × 24 × 5 + 36 = 1440 + 36 = 1476 cm²
 
        
             
        
        
        
The distance of point a from translated b is 9.2 units and the distance of point b from translated b is 3.6 units
<h3>What is a line?</h3>
A line is the distance between two points.
Analysis:
point a( -3,1) point b(2, -6) point translated b(-1, -8)
Distance ab = 
Distance ab =  = 9.21 units
 = 9.21 units
Distance btb =  = 3.6 units
 = 3.6 units
In conclusion, the distance of b from a is 9.2 units and b from b is 3.6 units.
