I was hoping there was some non-trig way. Most of the math I do doesn't involve trig, and so I'm not very good at it.
I honestly don't believe that you tried hard enough yet, or that the math is not for your level if you are still getting confused.
Umm... I have no idea what that formula is, but can't you just plug in 5 for F and V and solve for E? Seems pretty simple IMO compared to some of the other problems you've posted.
This is a system of equations. Let s be the price of a shirt and b be the price of a belt. Turn words into math. Here is one of the equations:
s = 3b.
Find the other and solve. I'd recommend using substiution.
In the last hour, you posted 8 questions, and in two hours, 9. I don't think you need that many questions to understand something like prime factorization or basic probability.
I'm fairly certain that's correct, unless you can point out where you think I made a mistake.
You know, I think you are just giving your hw to us. That is cheating, you know. You are really not learning and you have to try to solve them first! Most of these problems have a similar structure, so you should maybe ask for 2 questions and try to do the rest yourself after reading the explanations. That is how you really learn.
Read carefully-that says inclusive!
Find the savings plan balance after 12 months with an APR of 2% and monthly payments of $200.
Count how many integers are in that range, which is 20-10+1=11. Now divide that by the total number of choices, which is 99-0+1=100. So, your answer would be 11/100, if I'm not mistaken.
Since there 100 numbers in total and 10 numbers that are "successful", 10/100=1/10 is the answer.
50000 / 0.06 =$833,333.33 - This is a "Perpetual Annuity"
FV=833333.33; R=0.06/12; N=12*30;PMT = FV*(((1 + R)^N - 1)^-1* R);print" PMT =$",PMT
PMT =$ 829.59
Yeap, they have no way of knowing if you phrase it differently and have different usernames on here, and on AoPS.
You can find the area of the triangle by using the formula: Area = ½·a·b·sin(C)
The triangle part has got me stumped, but then, I haven't really given it a lot of thought.
so 4 suits and 3 J Q and K's per suit right
4*3=12 so
12 out of the 52 cards are the ones we want
12/52 =3/13 =.023
and that's as a percent is around 2.3%

hope this helps
Find the prime factorization of 715 first, and you will realize that there is only one answer that will work.
Also, this problem has the audacity to assume we know common English words! Outrageous. Just kidding. I don't know why I said that.
