Answer: The number of dogs in all of the city's animal shelters is puppies = 270
Step-by-step explanation:
Given: A random sample of dogs at different animal shelters in a city shows that 10 of the 55 dogs are puppies.

The number of dogs in all of the city's animal shelters is puppies =
Hence, The number of dogs in all of the city's animal shelters is puppies = 270
The lowest common denominator is lcm(5, 3), which is 15.
The sum of 2/5 + 5/3 + 9/3 is 6/15 + 25/15 + 45/15, which is 76/15 or .
Answer:
Option (B)
Step-by-step explanation:
Given sequence is 45, 135, 405, 1215, 3645..........
Since it's a geometric sequence,
Common ratio of each successive term to the previous term
r =
First term of the sequence 'a' = 45
Explicit formula of a geometric sequence will be,
Recursive formula of this sequence will be,
,
Therefore, Option (B) will be the answer.
