Using proportions, it is found that the better deal, on a per ounce basis, is given by:
- A a 30 oz. box of Tasty Wheats for $4.20
<h3>Proportion</h3>
- To find the better deal, we use <em>proportions </em>to find the cost per ounce, that is, dividing the cost per the amount of ounces. The <em>better deal </em>is the one with the smaller cost per ounce.
For each option, the costs per ounce are given by:
- A a 30 oz. box of Tasty Wheats for $4.20:

- B a 24 oz. box of Cherry Oats for $3.60

- C a 42 oz. Box of Giganto Flakes for $6.30

- D a 42 oz. Box of Giganto Flakes for $6.30

Due to the <em>smaller cost</em>, option A is the better deal.

Answer: 456 chairs
Step-by-step explanation:
If there are 6 round tables with 7 chairs each you would multiply 7, 6 times (7 x 6) = 42
If there are 23 rectangular tables with 18 chairs each you would multiply 18, 23 times. ( 18 x 23) = 414
Then you add up all the chairs, 456 chairs total.
 
        
             
        
        
        
Answer:
B. ZJ = 85
C. KH = 68
Step-by-step explanation:
Given that ZK, ZL, ZM are perpendicular bisectors of ∆GHJ, they form a circumcenter which is equidistant from the vertices of ∆GHJ. According to the circumcenter theorem, ZH = ZG = ZJ = 85.
Also each median formed is equal. This means: KH = GH, LH = LJ, MG = MJ
Since HG = 136, KH = ½ of 136 = 68.
The two options that are true are: 
B. ZJ = 85
C. KH = 68
 
        
             
        
        
        
Answer:
The answer to your question is: x = 22
Step-by-step explanation:
If line a is parallel to line b, 4x + 28 = 116 (corresponding angles)
 
                                       4x + 28 = 116
                                       4x = 116 - 28 
                                       4x = 88
                                         x = 88/4
                                         x = 22
