Answer:
32%
Step-by-step explanation:
165/125=1.32
percent change would be 32% because when you add 32 to 100 then divide by 100, you will get the 1.32. and 1.32 is the change in 125 and 165. you would multiply 125 by 1.32 to get 165.
The answer is 26 and 16
26-16=10 so thats correct
and
26+16=42
14. Fourteen is the answer
Answer:
2 + (-2) = 0
Step-by-step explanation:
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.
