Answer:
C. Yes, 3.5.
Step-by-step explanation:
If there is a relationship of direct proportionality for every ordered pair of the table, then the constant of proportionality must the same for every ordered pair. The constant of proportionality (
) is described by the following expression:
(1)
Where:
- Input.
- Output.
If we know that
,
and
, then the constants of proportionalities of each ordered pair are, respectively:









Since
, the constant of proportionality is 3.5.
The area of a triangle is found by multiplying the base by the height, then dividing that by 2:
Area = 10 * 7 = 70
70 / 2 = 35 square yards.
