I think you meant for the three plays. If I'm incorrect, leave a comment below this answer and I'll edit my answer.
Play One = + 7 yards.
Play Two = - 15 yards.
Play Three = -18 yards
Net = 7 - 15 - 18 = - 26 yards. That means that they are 26 yards behind where the ball started for the first play. They are not in a very good position.
Answer:
Has a common ratio so it is a geometric sequence
Step-by-step explanation:
The common ratio of this geometric sequence is 1/2
We have to find out the number of trees planted per unit rate of time.
Kyla can plant 300 trees in 1 hour, so she can plant 300 trees in 3600 seconds. This implies that she can plant
trees per second.
On the other hand, Mia can plant 1 tree in 13 seconds, so she can plant
trees per second.
Working together they can plant
trees per second, i.e. it takes them 156/25 seconds to plant a tree.
We conclude that they plany 100 trees in
seconds
