It's 42, here's a quick trick to do this, so we know there's 7 movies, and to find the combination we know we can't choose 2 of the same movie, so to make this part easier , in your head take one movie from the stack out of the stack now there's 6 movies. It's now just the "plug and play" step , (7)*(6)=(42)
I'm sorry If this is to long of an explanation, but I hope that this helps you understand on how to do this problem. Have a nice day :)
Make a proportion the sales tax is a percent of the total purchase and you just have to figure that out. 1,200/100=72/x solving this i get 6% sales tax using that. I find the rest by taking 6% of 2500 =150. And for part b make another proprtion x/100=108/6. And i get 1800 dollars
Answer:
X = 7.24 or 7.2
Step-by-step explanation:
Tan46/1 = x/7
Cross multiply to get this outcome:
7tan(46)
Put into calculator
Then your answer will be X = 7.24 or 7.2
Hope that helps :)
I hope this helps you
slope = -1 x'= -3 y'=5
slope. (x'-x)=y'-y
-1. (-3-x)=5-y
3+x=5-y
y=2-x
