Answer: choice a.
Step-by-step explanation:
1 feet = 12 inches.
Sears tower = 1450 * 12 = 17400 inches.
Now,
48 : 17400
= 2 : 725
I think the answer is .4m^7n^8
Uhh I don’t know how to give it a clear explanation but all I did was multiply them
-0.8•-0.5= .4
M^2•m^5=m^7
n•n^7=n^8
Hope this helps some.
In the pattern, the values are increasing by 22 each time so for the 117th term you take 57 + 22 = 79
So, 117= 79
