Answer: 3 and 1/8 more
Step-by-step explanation: 
You can start by converting to the same fraction and making the second one improper, so 29/8 and 4/8. Subtract them to find the difference and  you are left with 25/8 or 3 1/8 gallons.
 
        
             
        
        
        
Answer:
4.72 hours/day
Step-by-step explanation:
Mean time spent watching TV (μ) = 2.8 hours a day  
Standard deviation (σ) = 1.5 hours a day
The 90th percentile (upper 10%) of a normal distribution has an equivalent z-score of roughly z = 1.282. The minimum time spent watching TV, X, at the 90th percentile is:
 
  
On a typical day, you must watch at least 4.72 hours of TV to be in the upper 10%.
 
        
             
        
        
        
Answer:
The answer is y = 20
Step-by-step explanation:
To find this, we need to turn it into an equation. Then we can follow the order of operations to solve. 
y - 12 = 8
y = 20

Answer:
1
Step-by-step explanation:
Let's start by prime factorizing (finding the prime factors) of 16 and 21:


We can see that they DO NOT have any common factors, meaning that their greatest common factor is 1.
