Answer:363
Step-by-step explanation:
We have to find partial sum for the sequence 243 , 81 , 27 ..... up to 5 terms(S5 given)
The sequence actually is 3^5,3^4.,3^3.....
Therefore first 5 terms are 1) 3^5 I.e. 243
2) 3^4 I.e. 81
3) 3^3 I.e. 27
4)) 3^2 I.e. 9
5) 3^1 I.e. 3
Adding all those no. we get partial sum of first 5 no. of the sequence
So, 243 + 81 + 27 + 9 + 3
= 363
Hope it helps!!!

Answer:
Extra Miles walked by Alana = 1.625 miles
Step-by-step explanation:
Alana = 4 3/4 or 19/4
Bhavesh = 3 1/8 or 25/8
Extra Miles Alana walked = 19/4- 25/8
Extra miles Alana walked = <u>19(2) - 25</u>
8
Extra miles Alana Walked = <u>38-25</u>
8
Extra Miles Alana Walked = 1.625 miles
