I believe it's the first answer choice.
Answer:
Since 1/2 mile is equal to 4/5 mile, so we will solve this using proportions. 1/2 inches : 4/5 mile : ? : 1 mile. So the answer would be 5/8 inch. We cross multiply 1 by 1/2 then divided by 4/5 which gave us 5/8.
Step-by-step explanation:
So B 5/8 PLEASE MARK BRAINIEST.
1 mile = 1.6km.
so
100 miles x 1.6km = 160.
The number of km between two cities is 160km.
Answer:
g(n) = g(n-1) -15
g(1) = -65
Step-by-step explanation:
We can find the recursive formula from the explicit formula for this arithmetic sequence by substituting 1 and (n+1) for n in the explicit formula.
__
g(n+1) = -50 -15(n+1) = (-50 -15n) -15 . . . . . find g(n+1)
g(n+1) = g(n) -15
and ...
g(1) = -50 -15(1) = -65
Then the recursive formula can ge written as ...
g(n) = g(n-1) -15
g(1) = -65

<em>Additional comment</em>
We found g(n+1) = g(n) -15. Substituting n-1 for n in this formula puts it in the form we need for answering the question:
g((n-1)+1) = g(n-1) -15
g(n) = g(n -1) -15
Either of these forms tells you how to get the next term from the previous one.
