Answer:
3.63 * 10^19
Step-by-step explanation:
Given that :
Number of choices to select = 12
Category available :
Blues - 14
Country - 25
Disco - 21
To select an equal number of song for each category ; then 4 songs will be selected from each :
Using combination :
(14C4 * 25C4 * 21C4)
Since the order matters for the 12 selected songs ; it thus requires 12 permutation
Thus ;
(14C4 * 25C4 * 21C4) * 12!
nCr = n! / (n-r)!r!
Using calculator;
14C4 = 1001 ;
25C4 = 12650
21C4 = 5985
12! = 479001600
Hence,
(1001 * 12650 * 5985) * 479001600
= 36301596217286400000
=3.63 * 10^19
Answer:
100 tiles
Step-by-step explanation:
You would set up the equation like this.
1.25t=0.75t+50
Then, solve for t and it will show you how many tiles you will need to buy for it to be equal.
Answer:
the answer is c
Step-by-step explanation:
5/8-3/8 is 1/4 + 2 is 2 1/4 then put into improper fraction
Set up a proportion.
flagpole/shadow = woman/her shadow.
f/s1 = w/s2
f = 42.9
s1 = 253
w = 6.2
s2 = ??? = x
42.9/253 = 6.2 / x
42.9 x = 253*6.2
42.9 x = 1568.6
x = 1568.6 / 42.9
x = 36.56 The womans shadow is 36.56 feet long <<<< ===== answer.
