A. The scientific notation for 50,000,000 is 5 x 10^7 (to the 7th power)
B. After squaring 50,000,000 you'll get <span>2500000000000000. In </span>scientific notation, this is 2.5 x 10^15 (to the 15th power).
C. I think what it's asking is how I solved part B... this could be wrong, double check it. I solved it by multiplying 50,000,000 x 50,000,000 and then converting the product into scientific notation.
Hope this helps, if you have more questions, message me or comment under this post!
The 30th, I believe, would get all gifts.
Answer: 7/3
Step-by-step explanation:
1. you multiply 2/7 on both sides to get x by it self.
2. then you can cross out both the 2's and get 7/3 as the final answer.
11.9%
This is because after the markups, A will cost 226.80 compared to C's 200. You can then divide the C cost by the A cost to see what percentage would be required to get lower. <span />
