Answer: 1/2 x 1 = 1/2
1/3 x 3 = 1
Step-by-step explanation: 100% Sure! :D
The most realistic answer is A.
You can start by taking 13.85 and finding 4% of that number. You get 0.554, but you round it to the nearest hundredth making it 0.55. Yes the tax is 0.55 cents, but the problem is asking the price including sales tax. So you add 0.55 to 13.85 and get 14.40.

Answer: 6 minutes</h3>
=======================================================
Explanation:
The plane needs to go up 29,000-8,000 = 21,000 feet
It does so at a rate of 3500 ft per min
So it needs 21000/3500 = 6 minutes to get to the proper height.
---------
You can think of it like the equation
3500x = 21000
where x is the number of minutes needed. Dividing both sides by 3500 solves to x = 6.
-----------
Or you could think of it like this
1 minute = 3500 feet
1/3500 minute = 1 foot (divide both sides by 3500)
1 foot = 1/3500 minute
21000 feet = 21000/3500 minute (multiply both sides by 21000)
21000 feet = 6 minutes
This shows that to go up 21000 feet, the plane needs 6 minutes to do so.
Hope you don’t mind reading handwriting. I named two of the angles to make the explanation easier
