Step-by-step explanation:
The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are
and
.
To find the constant of proportionality, all we have to do is divide any value of
by its corresponding value of
. Let's take the values in the first row of the table. We know that
and
, so the constant of proportionality is
. Hope this helps!
Answer:
Amount of fencing: 32 feet
Amount of soil: 63 square feet
Step-by-step explanation:
Fencing: In a rectangle, the opposite side is the same length. So we do:
9+7+9+7 = <u>32 feet</u>
Soil: The soil is the area. Area is equal to length times width. Length is 9 and width is 7, so we do:
9 x 7 = <u>63 feet squared</u>
A^2 + b^2 = c^2
8^2 + 15^2 = 17^2
64 + 225 = 289
289=289
It is a triangle because the numbers match the Pythagorean Theorem.
