The board A is 8 inches. If you use 3/4 of an 8-foot-board. Then you're left with 2 feet.
3 6
-- = --
4 8
8 - 6 =2
(8= the length of the board)
1/3 of 2 feet = 8 inches
1 24 24
-- x -- = --- = 8 inches
3 1 3
(24= the equal amount of inches in a 2-foot-board)

After each charging, a battery is able to hold only 97% of the charge from the previous charging. The battery was used for 18 ho

Cerrena [4.2K]

Answer:

The total nuber of hours that the battery can be used over its lifetime is 600.

Step-by-step explanation:

We use an infinite geometric series to solve this question.

The sum of all values of an infinite geometric series is given by the following equation:

$S = \frac{a_{1}}{1 - r}$

In which $a_{1}$ is the first term and r is the common ratio.

After each charging, a battery is able to hold only 97% of the charge from the previous charging.

This means that $r = 0.97$

The battery was used for 18 hours on its first charge before it had to be recharged.

This means that $a_{1} = 18$

What is the total number of hours the battery can be used over its lifetime?

$S = \frac{18}{1 - 0.97} = 600$

The total nuber of hours that the battery can be used over its lifetime is 600.
