Answer: Choice A</h3>
=========================================================
Explanation:
A proportional linear relationship is of the form y = kx
We can solve for k to get k = y/x.
Based on that, we can prove a table is a proportional linear relationship if and only if each column of x,y values divide to the same number.
Choice A shows that y/x = 2/8 = 1/4 for the first column; however, y/x = 8/16 = 1/2 for the second column. The outputs 1/4 and 1/2 not being the same indicates we don't have a constant k value for all of the columns. This is sufficient to show that table A is not a proportional linear relationship.
-------------
In contrast, table B is a proportional linear relationship because we have these four divisions that lead to the same value (1/8)
- Column One: y/x = 2/16 = 1/8
- Column Two: y/x = 4/32 = 1/8
- Column Three: y/x = 6/48 = 1/8
- Column Four: y/x = 8/48 = 1/8
Showing that k = 1/8 for table B. The equation here is y = (1/8)x. We can rule out choice B.
I'll let you check out tables C and D on your own, but you should find that a similar situation shows up as did with table B. This indicates tables C and D are also proportional linear relationships. We can rule out choices C and D.
Answer: 4.8 liters
Step-by-step explanation:
Let x liter of water is added with y liter of 25% beach solution.
Thus, According to the question,
x + y = 12 -------(1)
0% of x + 25 % of y = 15 % of 12
25 % of y = 15% of 12
Put this value in equation (1),
We get,
Therefore, the quantity of water = 
And, the quantity of 25% bleach solution = 
Since bc = 6, that makes db = 3 and cd = 3rad3
cd (2) = ac. so ac = 6rad3
so to get ad, you square ac which = 108, square cd which = 3rad3 which equals 27. 108 - 27 = 81. the sqaure root of 81 is 9. ad = 9
69 or 420 feet is what i think it is
Answer:
is going to give you a decimal as then you divide it by 2 and then multiply that number by 4 hope this helps
