Hey You!
This question is asking us, "75 is 75% of what number?"
75 × 100 / 75 = 100
The original cost was $100.
Answer:
I’m pretty sure it’s 73% but I’m not completely sure
Yes it is already simplified because there is nothing else that you are able to do to it.
Answer:
(d) 428,820,000 pounds of garbage
Step-by-step explanation:
Your calculator or spreadsheet can give you the product of two numbers expressed in scientific notation.
(1.643×10^3 lb/resident) × (2.61×10^5 residents) = 4.28823×10^(3+5) lb
≈ 428.82×10^6 lb
= 428,820,000 lb . . . of garbage
