Answer:
4368 ways
Step-by-step explanation:
Use nCk for this. 16C5. This is 
. This becomes
. This is 
due to 16! and 5! canceling out. This becomes 4368.
Multiply 8/3 by 3/5 and get 8/5
Answer:
two irrational solutions
Step-by-step explanation:
you can use the quadratic formula: (b ± √b²- 4ac)÷2a
a = 5, b = -2, c = 6
= [2 ± √(-2²)-4(5)(6)] ÷ 2(5)
= (2 ± √4-120) / 10
two complex solutions: (2+√-116)/10, (2-√-116)/10
To find the amount increase in price, you will calculate what 60% of the $38 is by multiplying 0.6 and 38
0.6 x 38 = $22.80 is the amount of increase.
The retail price is found by adding the increase to the cost.
$38 + $22.80 = $60.80.
