Answer:
Step-by-step explanation:
To calculate combinations, we will use the formula nCr = n! / r! * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time. To calculate a combination, you will need to calculate a factorial.
Let the initial price be 100. Price after 1 month is 101.9. common ratio is r = 101.9/100 = 1.019
After 12 months, the price will be:
A1 x r ^n-1
= 101.9 * (1.019)^12-1
= 101.9 * 1.019^11= 125.34
So the yearly increase would be: 125.34 – 100 = 25.34
Therefore, the yearly price rise percentage is 25.34/100 x 100 = 25.34%

If you really want to know LOL
Question 1: 11 * 34 = 374
Question 2: 374 + 10=384
Answer:
D
Step-by-step explanation:
You don't need any real math to guess at the right answer.
Choice A requires at least 33+32+32=97 feet of fence, hence you an rule it out because that is more fence than you have.
Choice B requires at least 16+16+16=48 feet, hence you can rule it out because it does not use all your fence and you can get more area by using it all.
Choice C requires at least 48+16+16=80 feet of fence, which is more than you have.
Choice D requires at least 32+16+16=64 feet of fence, so this is the right choice.
