What is the volume of the crushed ice?
volume of the cone = π r² h/3
volume of the small cone = 3.14 * (3in)² * 3in/3
volume of the small cone = 3.14 * 9in² * 1in
volume of the small cone = 28.26 in³
volume of the big cone = 3.14 * (3in)² * 15in/3
volume of the big cone = 3.14 * 9in² * 5in
volume of the big cone = 141.30 in³
volume of the crushed ice = 141.30 in³ - 28.26 in³ = 113.04 in³
The electronics store made $13,592. If this helps, please make this answer brainliest, I would really appreciate it! Have a nice day to whoever is reading this! :)
- I’m assuming the expression implies the following:
(1-n)/(n^2 - 1)
The steps goes as follows:
= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)
At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.
= -1/(n+1) , which is the answer
Note: You could also see it as 1/-(n+1) or 1/(-n-1)
So 10 questions is 100% you missed 30% of the questions so you would do 100%-30% which is 70%
The greatest factor that these have in common are that they are numbers
