x = 7
y = 8
All I did was assume x was 7 and y was 8. I added 4, 6, 7, 8, and 10 together. I got 35. Then, I divided by five (since that's how many numbers are shown) and I got 7 for the mean. 7 is the median, and the 7 is the mean gotten from 4, 6, 7, 8, and 10. Therefore, x must equal 7 and y must equal 8.
 
        
             
        
        
        
All you do is divide. 
330/390= 0.846
round it: 0.85 
Answer is about 85%
        
             
        
        
        
Answer:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).
Step-by-step explanation:
 
        
                    
             
        
        
        
We know that AB and CD are parallel.  This allows many assumptions.
From that we know that angle A and angle D are congruent.  
That means that x + 8 = 2x - 22 and we can solve for x
x + 8 = 2x - 22
x + 30 = 2x
30 = x or x = 30
We know from the figure that angle B is x or now that we solved for x is 30 degrees.  Also, we know that both angle A and angle D are 38 degrees.  Now we can solve for the vertical angle E which has a measure of y degrees.  A triangle has the sum of its angles equal to 180 degrees.
We can set up an equation like this 30 + 38 + y = 180
30 + 38 + y = 180
68 + y = 180
y = 112 degrees
That is how you would solve this problem
        
             
        
        
        
First you would have to find how many inches the sign is, then you would find the radius and then multiply that by 3.50
