A third are spotted so that would mean 2/3 are not spotted so if you take 1200 divide it by 3 and then multiply it by 2 you get 800 which is your answer
        
             
        
        
        
To <span>transform the quadratic equation into the equation form (x + p)2 = q we shall proceed as follows:
3+x-3x^2=9
putting like terms together we have:
-3x^2+x=6
dividing through by -3 we get:
x^2-x/3=-2
but
c=(b/2a)^2
c=(-1/6)^2=1/36
thus the expression will be:
x^2-x/3+1/36=-2+1/36
1/36(6x-1)</span>²=-71/36
the answer is:
1/36(6x-1)²=-71/36
        
             
        
        
        
Answer:
y = 1/3
Step-by-step explanation:
<u>Step 1:  Factor</u>
9y^2 - 6y + 1 = 0
(3y - 1)(3y - 1) = 0
(3y - 1)^2 = 0
<u>Step 2:  Solve for y</u>
3y - 1 + 1 = 0 + 1
3y / 3 = 1 / 3
y = 1/3
Answer:  y = 1/3

Dominics son is 45inches tall
<u>Step-by-step explanation:</u>
Let his sons height be 'h' 
If Dominic is 72 inches and casts a shadow of 60 inches. His son casts a shadow of 50 inches. 
Then We can say that, 
h = 50 x (72/60) 
h = 45 inches
Dominics son is 45inches tall
