Answer:
So first lets find g(-1)
so we plug in the answers:
-2 * -1 ^2 -4
-2*1-4 = -2-4 = 
-6
Now lets solve for f(-2)
-2^2-3
4-3=1
-6+1 = 5
3*5 = 15
Im getting answer of 15 but it shows -15 or something, so I dont know if I got it wrong or if its like a dash then the answer.
 
        
             
        
        
        
Answer:
each person (including Alana) gets 25mL of water
Step-by-step explanation:
since there is 4 ppl, and 100mL of water, you divide 100/4. Therefore, each person gets 25mL of water:)
 
        
                    
             
        
        
        
So say we have the number: 54,321
The 5 would be worth 50,000 meaning it's in the ten thousands place. 
The 4 would be worth 4,000 meaning it's in the thousands place. 
. 
The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place
. 
Hope that helps :) 
 
        
             
        
        
        
1/5 of a litre is 0.2 litres
1 litre minus 0.2 litres is 0.8 litres so 
0.8 divided by 5 (glasses) is 0.16 litres in each glass
