Here's how to do dividing in a certain ratio:
-- You want to divide up the whole thing in the ratio of 
     4 parts, 5 parts, and 9 parts. 
-- How many parts all together ?  (4 + 5 + 9) = 18 parts all together.
-- The whole thing is 180, and that's 18 total parts.
    So each part is  (180/18) = 10 degrees.
4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.
Check:  (40 + 50 + 90) = 180 .                yay!

For the second one, I think there are some words missing.
        
             
        
        
        
Answer:
5 more games to be won for the 50% success rate.
Step-by-step explanation:
Total number games played = 500
Number of successful games = 49% of 500
                                                  = 500 × 
                                                  = 245
Number of successful games for the success of 50% = 500 × 
                                                                                         = 250
Therefore, number of game you have to win more = 250 - 245 
                                                                                     = 5 games
 
        
             
        
        
        
Answer: 6
Step-by-step explanation:
7 - 3 = 4
3 - 4 = 0
0 - 6 = -6
 
        
             
        
        
        
You have that:
 - Her contribution from her salary <span>to her 401(k) plan, </span>is: 12%.
 - Her annual salary is: $55,700.
 Then, to solve this problem and calculate her pretax income, you must following the steps below:
 1. You must calculate the amount that Violet contributed to her 401(k) plan. So, you have:
 12%/100=0.12
 ($55,700x0.12)=$6,684 
 2. Now, you must subtract her annual pay ($55,700) by the amount obtained ($6,684), as below:
 Pretax income= $55,700-$6,684
<span> Pretax income=$49,016
</span><span>
 What is her pretax income?
 The answer is: Her pretax income is </span>$49,016
        
                    
             
        
        
        
Answer:
(0, 8).
Step-by-step explanation:
The y intercept occurs when  = 0, so we have the equation:
y = -3(0) + 8
y = 0 + 8
y = 8.
The answer is (0, 8).
