Answer:
(about) 61.1
Step-by-step explanation:
To find the height, or H, we can use
sin (45 degree angle) =H/85
rearrange as H=85* sin (45 degrees) =(about) 61.1
9000 tens are in 90,000
Because:
90,000÷10=9000
If it is too much work, just cross of one zero from 90,000 which becomes:
9000
Hope this helps!
It wouldn’t let me cancel to answer this but i do not know the answer and i had to type something to exit it. i’m sorry
Notice, you've got a diameter in inches
and a linear velocity in miles
thus, you'd need to convert first

now, whatever that is, you'll need to divide it by a revolution, recall, a revolution is

thus
