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:
Step-by-step explanation:
The leftmost line segment has a slope of -2 and (-1,-1)  is a point on the line. 
Equation: y = -2x-3
middle line segment has a slope of 0 and  y-intercept of -2.
Equation:  y = -2
The rightmost line segment has a slope of 1.5. (5,0) is a point on the line.
y = 1.5(x-5) = 1.5x-7.5
 
        
             
        
        
        
Set this up like a right triangle with the height of the triangle as 30, the angle across from that side, the reference angle, as 55, and the base is your unknown, x.  This means that we have the angle, the side across from it, and the side adjacent to it.  That sounds like the tangent ratio to me!  Tangent of the angle is the side opposite over the side adjacent: 

.  Solving for x: 

.  Do that on your calculator in degree mode to get that the distance between the base of the ladder and the wall is 21 feet
 
        
        
        
50^2 = 50 to the power of 2 = 2.5 × 10^3
Explanation:
(50) to the 2nd power or simply '50 to the 2nd' is obtained by multiplying 2 times the base 50 by itself. So,
50^2 = 50 × 50 = 2.5 × 10^3
Note: We say that 50 is the base, 2 is the exponent, and the whole thing or the result is a power of 50.
