The manager of a food court estimates that he needs 7 pretzels for every 20 people who attend a hockey game. what constant of proportionality relates the number of pretzels to people

0.35.

Step-by-step explanation:

We have been given that the manager of a food court estimates that he needs 7 pretzels for every 20 people who attend a hockey game.

We will use proportions to solve our given problem.

This means that number of pretzels per people is 0.35, therefore, the constant of proportionality is 0.35.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
