Answer:

Step-by-step explanation:
Pattern 1 consists of 
 small squares (here n = 1 and
 small squares (here n = 1 and  ).
).
Pattern 2 consists of 
 small squares (here n = 2 and
 small squares (here n = 2 and  ).
).
Pattern 3 consists of 
 small squares (here n = 3 and
 small squares (here n = 3 and  ).
).
Thus, pattern n consists of
 small squares.
 small squares.
 
        
             
        
        
        
Your max amount for this is $20. Let's say x represents the number of gallons.
20 ≥ 3.2x
x = 6.25 gallons
If they're asking for integers or whole numbers, you'd round down to 6 because you only have enough money for 6 full gallons. If you rounded up to 7, you wouldn't be able to fill it up completely because then you'd be over your $20.00 budget for gas.

Answer: 42.9%
Step-by-step explanation:
Percent error is the difference between the measured and known value, which is divided by the known value, and then multiplied by 100%. 
Percent error = (Estimated number- Actual number)/Actual Number × 100.
= (60 - 42)/42 × 100
= 18/42 × 100
= 0.429 × 100
= 42.9%
