Horse- 50l
sheep-4l
chicken-200ml
first you have to convert all the symbols into one, so we'll convert liters into milliliters,
 
1000ml=1l
horse= 50 ×1000=50000ml
sheep=4×1000=4000ml
chicken= 200ml
so now we have to multiply them by the number of animals,
h=50000ml×3=150000ml
s=4000×15=60000ml
c=200×12=2400ml
now add them together,
150000+60000+2400=212400ml
convert it into litres, 
212400÷1000=212.4l
answer= 212.4 l 
        
             
        
        
        
 Answer:
I think it's the last one! In an experiment, one group is studied over a short period of time---
 
        
             
        
        
        
Its going more horizontal because the slope has you go up 1 and right 4, meaning you are going right more than you are going up
        
             
        
        
        
Answer:
(7x + 10y)
Step-by-step explanation:
To find this add (3x - 4y) to itself to calculate to lengths of the shorter sides.
(3x - 4y) + (3x - 4y) = 6x - 8y
Subtract this from (20x + 12y) 
(20x + 12y) - (6x - 8y) = 14x + 20y     Divide this by two to get the length of one side
14x + 20y / 2 = 7x + 10y
