Answer:
1287
Step-by-step explanation:
Number of people in elevator , n = 8
Number of floors, r = 6
Since they all look alike, arrangement doesn't matter, the we use combination :
(n+r-1 r - 1) = (8+6-1 C 6-1) = 13C5
Recall:
nCr = n! / (n-r)!r!
13C5 = 13! / (13-5)!5!
13C5 = 13*12*11*10*9 / 5*4*3*2*1
= 1287
Answer:
-3
Step-by-step explanation:
To solve the inequality, you need to isolate/get the variable "p" by itself in the inequality:
5p + 26 < 72 Subtract 26 on both sides
5p + 26 - 26 < 72 - 26
5p < 46 Divide 5 on both sides to get "p" by itself


p < 9.2 Your answer is A
Answer:
$918.02
Step-by-step explanation:
As each tire costs $213.99, you will be multiplying that by 4:
$213.99*4 = $855.96
Now you will have to add the tax to the price. You will do the following:
$855.96*.0725 = 62.0571
You will round that to $62.06
$855.96+$62.06
The total would be $918.02
