Answer:
2.5r D is the answer.
Step-by-step explanation:
It is 2.5 r because it makes the most sense for a real world situation like this.
It can't be answered because it has to have a variable or number after log200 because that's how you get 2.301.
Give me the variable or number and I'll answer it from there.
(2) 0.55
16/29 = 0.5517 = 0.55
