Answer:
This isn't a question, you just said some things. What does "what si the scale of diagram b" mean? I'd really like to help but this is confusing
Step-by-step explanation:
pretty sure its D but idk
The answer would be 10 tickets because 400 divided by 40 equals 10
The numbers increase by 10 (4*10=40) and then 100 (40*100=4000).
The explanation is above. Hope this helps
that is the answer 9+10=19
