Let, that number = x
It would be: x * 0.65 = 52
x = 52 / 0.65
x = 80
So, that number and your answer is 80
18 is 45% of 40
45%/100 = 0.45
0.45*40=18

Answer:
C. 8^x/3
Step-by-step explanation:
According to algebraic principles, if n is the root of a number, then that number to the power of 1/n is equal to it. This would mean that n√a = a^1/n. 
This would mean that 3√8 = 8^1/3. When there is a power added to a radical expression such as this, that power will go on the denominator. So (3√8)^2 for example is equal to 8^2/3, and in your case, (3√8)^x = 8^x/3
looking back on the fact that this was added 2 days ago i dont think this helped on your quiz
 
        
             
        
        
        
Answer:
   The quadratic curve has the best correlation to the given data.
Step-by-step explanation:
Enter the data into a spreadsheet or graphing calculator and try the different regression options to see which gives the highest R-value. Here, the quadratic regression does that.
 
        
             
        
        
        
Slope is 2/1 , because the formula to find the slope is rise/ run
= 6/3
= 2/1
