Answer:
1/5,764,801
Step-by-step explanation:
We have this as follows
All we have to do is use the laws of indices
We have it that;
a^-x = 1/a^x
a^x/a^y = a^(x-y)
Applying these laws;
7^-3/7^5
= 7^-3-5
= 7^-8
= 1/7^8
= 1/5,764,801

QUESTION:
A battery was charged. When the charging began, it was 23 percent full. After 30 minutes of charging, the battery was 89 percent full. how fast did the battery charge and how long did it take?
Solution :
<u>Given</u>
- Initial amount of charge = 23%
- Amount after charge = 89%
<u>procedu</u><u>re</u>
Let the rate of charging be r .
r = (change in charge level) / (time interval) = (89% - 23%) / (30 min) = 2.2 % per minute
charge = (rate of charging)(time) + (initial charge)
100% = r*t + 23%
100% = (2.2 %/min)t + 23%
Solve for t and get
t = [(100 - 23) / 2.2]
Answer = 35 min
