Answer:
You should <u>carry 2 other batteries.</u>
Step-by-step explanation:
If the average life of each battery tends to last 6.9 months, and what you need is a year of battery supply, you probably need to carry two batteries.
The battery inside the flashlight has probably already spent much of its half-life.
We are told that the flashlight already has a battery inside, the batteries are discharged inside the flashlight even if the flashlight is not being used.
Which means that the average life of that battery is wearing out.
It would take 2 more batteries in addition to the one already inside the flashlight to supply the need for these for a year.
Answer:
x +3
Step-by-step explanation:
You can solve this by factoring.
The numbers have to add to 10 and multiply to 21.
The first numbers that should come to mind are 7 and 3
(x+3)(x+7)
x+3 is the shorter side and there you go :)
-1.1 should be the right answer
The Answer should be either x=15 or x=5 I got both.
14.38 is the awnser because you just cut the circumfrance in a weird way that would take to long to expmain, but it's 14.38.
