Given that there are 12 persons, the first choice may be in 12 different ways, the second choice may be in 11 different ways, ther third in 10 different ways, the fourth in 9 different ways and the fith in 8 different ways, for a total of:
12x11x10x9x8 different combinations.
Now you have to take in account that 5x4x3x2 are repetitions. So you have to divide the previos counting by 5x4x3x2.
(12x11x10x9x8)/(5x4x3x2) = 792 different subcommittees.
Also, you can use the formula for combinations: C(m,n) = m! / (n! (m-n)!)
C (12, 5) = 12! / (5!) (12-5)! = [12x11x10x9x8x7!] / [5! 7!] = [12x11x10x9x8]/[5x4x3x2] = 792
Well, its a given more or less when referred to the measure of an Arc, it's usually meant the CENTRAL ANGLE made by that arc in this case, 148 is the CENTRAL ANGLE, so if BCD is 148 and BC is 105, then CD is the rest of the 148. 148 for the central angle, if we use up 105 for BC, how much is left over for CD?
That would be the % of pollutants removed, so the 2nd answer
5 pennies (5c)
9 nickels (45c)
21 dimes ($2.10)
15 quarters ($3.75)
We then all the totals together for how much money the bank has
$6.35
<h2>
Answer:</h2>
x = 37
<h2>
Step-by-step explanation: </h2>
x + x = 74
2x = 74
divide both sides by 2 which is
x = 37
