Answer:
oh I see. that's an interesting question but the problem is I hate maths
hi,
You have to use a formula which is known as of binomial coefficient which is :
k among n is : C ( n /k) = n! / k! ( n-k)!
! = factorial
ex : 5 object among 8 is : C ( 8/5 ) = 8 ! / 5! * ( 8-5) !
As 8! = 8*7*6*5*4*3*2*1 = 40 320
As 5! = 5*4*3*2*1 = 120
as 3 ! = 3*2*1 = 6
then : 40 320 / 120 * 6
40 320 / 720 = 56
Conclusion : there is 56 way to select 5 object among 8 of them.
ps : you can also use Pascal Triangle to do such a thing.
6 feet * 7 feet = 42 feet²
18 feet * 21 feet = 378 feet²
42 feet² was painted for $52
1 feet² will be painted for $52/42
378 feet² will then be painted for: ($52/42) * 378
= $468
Hence 18 feet by 21 feet will be painted for $468
Hope this helps.
41 necklaces can be made using 2017 beads where 49 beads are used to make 1 necklace.
The total number of beads for making jewelry with Yer = 2017
Beads require to make 1 necklace = 49 beads
The number of necklaces that can be made using 2017 beads when 49 beads are required to make 1 necklace will be:
Number of necklace = 2017 / 49
Number of necklace = 41.16
That is 41 necklaces can be made using 2017 beads where 49 beads are used to make 1 necklace.
Therefore, 41 necklaces can be made using 2017 beads where 49 beads are used to make 1 necklace.
