Answer:
Jacob ran 40 yards more than Ali.
Step-by-step explanation:
Football field is in the shape of a rectangle having dimensions 120 yards × 50 yards
Since Jacob runs around the perimeter of the field from one corner to other corner, therefore, distance run by Jacob =
Distance run by Jacob = 50 + 120 = 170 yards
Ali runs through the middle of the field diagonally on a straight line.
Therefore, distance covered by Ali =
=
=
=
= 130 yards

Answer:
D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.

Let us assume x = selling price of each soccer ball
y = daily profit earned from selling of soccer balls
Given that
Y=
where,
a = -6
b = 100
c = -180
Now we have to applied the formula which is as follows
x
x^1 = -2.05285
Now
x^2
x^2 = 14.6138
Based on this the option D is most appropriate as per the given situation
