The constant of proportionality of our given tables is; 5.
<h3>How to find the constant of Proportionality?</h3>
We are given that x and y are proportional, and this means that:
y = r*x
where;
r is the constant of proportionality.
We are given the table;
x y
7 35
12 60
20 100
Now, we can replace those values in our equation and get, for the first pair: 35 = r*7
r = 35/7 = 5
For the second pair:
60 = r*12
60/12 = r
r = 5
Thus, we can conclude that the constant of proportionality is 5.

Answer:
Option D.
Step-by-step explanation:
The given expression is (5r + 2)(3r minus 4)
Convert this expression into an algebraic expression.
(5r + 2)(3r - 4)
By distribution law,
= 5r(3r - 4) + 2(3r - 4)
= 15r² - 20r + 6r - 8
= 15r² - 14r - 8
Now convert the algebraic expression into the language form.
15r squared minus 14r minus 8
Therefore, option D is the answer.
The one that has less volume is cereal box b because as you can see the box is 12 inches so it's smaller so it might as well has less volume. Hope this help
