Answer:
A kitchen sink faucet
Step-by-step explanation:
0.5 gallon of water × 6 = 3 gallons
10 second × 6 = 60 seconds = 1 minute
   
0.75 gallon of water × 4 = 3 gallons
18 seconds × 4 = 72 seconds = 1 minute 12 seconds
1 minute is faster than 1 minute and 12 seconds by 12 seconds
so a kitchen sink faucet
  
        
             
        
        
        
The area is 150 feet^2. The dimensions are 10x15 feet.

Answer:
The number of boys last year will be 50 boys 
Step-by-step explanation:
330 members with 240 adults 
The number of children will be;
330-240 = 90 
2/3 of 90 are boys 
= 2/3 * 90 = 60 boys 
Number of girls is 90-60 = 30
Ratio of adults:boys:girls 
= 240:60:30
divide through by 30
= 8:2:1
b) A year ago, there were 200 adults but the ratio still remains same 
Let the number of girls be x, the number of boys will be 2x 
Thus, total number is 200 + x + 2x = 200 + 3x 
Total ratio is 8 + 2 + 1 = 11
mathematically;
8/11 * (200 + 3x) = 200
8(200 + 3x) = 11(200)
1600 + 24x = 2200
24x = 2200-1600
24x = 600
x = 600/24
x = 25
So the number of boys will be 25 * 2 = 50
