Step-by-step explanation:
Given


Required
Determine the possible number of combinations
The question emphasizes on "selection" which means "combination".
So; To answer this question, we apply the following combination formula:

In this case:


The formula becomes:






<em>Hence, there are 15 possible combinations</em>

14000+7x=35x (x being the number of books) solve for x and you have your answer. 14000=35x-7x=28x therefore x=14000/28=500 so he needs to sell 500 books before he breaks even.
        
             
        
        
        
Answer:
<h2>The Answer would be (0.25, -0.25)</h2>
Step-by-step explanation:
Since you started at the origin of the plane, it would be obvious that your place would be 0.25 on the x-axis. The template for this would be (x,y) x- right and left. y- up and down. On the y-axis, the bug moved 0.25 DOWN to point A. That would be a negative since on the y-axis, it counts up to positives and down to negative. Similar to the x-axis, it counts right to positives, left to negatives. Hope this helped!
 
        
                    
             
        
        
        
Answer:
408.2sq inches
Step-by-step explanation:
Area of the cylindrical box = 2πr(r+h)
r is the radius  = diameter/2
r = 10/2 = 5in
h is the height = 8in
Substitute
Area of the cylindrical box  = 2(3.14)(5)(5+8)
Area of the cylindrical box = 2 * 3.14 * 5 * 13
Area of the cylindrical box  = 408.2sq inches
