Rosie went to the mall to buy new shirts for school. The store she was shopping in had a sale in which all the shirts were $8 each as long as she also bought one pair of shorts for $6. If Rosie spent $38 how many shirts did she buy?
Answer:
The common difference (or common ratio) = 0.75
Step-by-step explanation:
i) let the first term be
= 80
ii) let the second term be
=
. r = 80 × r = 60 ∴ r =
= 0.75
iii) let the third term be
=
. r = 60 × r = 45 ∴ r =
= 0.75
iv) let the fourth term be
=
. r = 45 × r = 33.75 ∴ r =
= 0.75
Therefore we can see that the series of numbers are part of a geometric progression and the first term is 80 and the common ratio = 0.75.
The answer would be where the points meet.
In this case it would be (1,-1)
Answer:
21
Step-by-step explanation:
1 side = 6 plants (including one in the corner)
3 sides = 5 plants each
