Answer: 6.04 inches
Step-by-step explanation:
Given: The actual height of the monument = 604 feet
The scale used by Corbins is 1 inch = 100 feet
It implies in Corbins model 1 feet 
Therefore, The height of the Corbins model in inches= 
Hence, the height of the Corbins model in inches= 6.04 inches
Answer is -1+15i that’s your answer
This question is best answered by finding the least common multiple of both 45 and 20. If a scenario indicates every so many, it would be like listing the multiples. It can be harder to list the multiples of bigger numbers (45, 90, 135, 180 and 20, 40, 60, 80, 100, 120, 140, 160, 180), so another strategy is to use prime factorizations. The prime factorization of 45 is <em>3</em> x <em>3</em> x 5 and the prime factorization of 20 is <em>2</em> x <em>2</em> x 5. The numbers that are the same in both prime factorizations are part of your answer. All other numbers (the italicized ones) also become a factor in your final answer, so 5 x 3 x 3 x 2 x 2 = 180. This means 180 minutes later they both start again at the same time. So 3 hours from 9 am is 12 noon.
