Answer: 49 cm^2
Step-by-step explanation:
The length of the small pink square box will be: 
L^2 = 9
L = sqrt( 9 )
L = 3
The length of the big pink square box will be:
L^2 = 16
L = sqrt( 16 )
L = 4
The length of the yellow square box will be:
4 + 3 = 7
The area of the third square box will be 
A = 7^2
A = 49 cm^2
 
        
             
        
        
        
She will need 6/8 because 3/4 the cup is divided into 8 so we need the denominator to be 8. we multiply 4 x 2 and what every we do to the top happens to the bottom so we also multiply 3 x 2. then we see that sara needs 6/8 cups of dish soap to make her bubbles
        
                    
             
        
        
        
X(30;0)
y(0;50)
substitue 0 for y and solve for x
substitute 0 in for x and solve for y
        
                    
             
        
        
        
Answer:
16,800 votes.
Step-by-step explanation:
In the singing competition 42,000 votes were counted.
The winner received 3/5 of the votes.
The part of the votes that the winner did not receive was 1 - 3/5 = 2/5
So the winner did not receive 2/5 of 42,000 votes which is equivalent to:
 = 16,800 votes.
 = 16,800 votes.
 
        
             
        
        
        
Y1 is the simplest parabola.  Its vertex is at (0,0) and it passes thru (2,4).  This is enough info to conclude that y1 = x^2.
y4, the lower red graph, is a bit more of a challenge.  We can easily identify its vertex, which is (-4,0), and several points on the grah, such as (2,-3).
Let's try this:  assume that the general equation for a parabola is 
y-k = a(x-h)^2, where (h,k) is the vertex.  Subst. the known values,
-3-(-4) = a(2-0)^2.  Then 1 = a(2)^2, or 1 = 4a, or a = 1/4.
The equation of parabola y4 is   y+4 = (1/4)x^2
Or you could elim. the fraction and write the eqn as 4y+16=x^2, or
4y = x^2-16, or    y = (1/4)x - 4.  Take your pick!  Hope this helps you find "a" for the other parabolas.
