9inches of ribbons are needed for wrapping each present. how many presents can be wrapped with 6 yards of ribbons?

with 6 yards of ribbons we can wrap 24 presents.

Step-by-step explanation:

For each 9 inches of ribbons, we can wrap one present, then if we have 6 yards we have:

1 yard = 36 inches

then 6 yards is equal to 6*36 inches = 216 inches

now, in how many pieces of 9 inches we can divide the 216 inches?

this is:

N = 216/9 = 24

for each one of those 24 pieces of 9 inches we can wrap a present, this means that with 6 yards of ribbons we can wrap 24 presents.

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.
