1.25 Dozen.

Step-by-step explanation:

Per means each. By Means Of

1.25 per muffin

Step-by-step explanation:

15 divided by 12 and you get 1.25

to make sure 1.25 times 12 you get 15 dallors

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.

a. -0.3 > -0.33
