A= appetizers ($6)
M = main dish ($9)
p= pays
4(a+M)÷4 = p
4(6+9)÷4 =
(24+36) ÷4 =
(60)÷4 = $15
p= $15.00
Answer:
Option A. 56
Step-by-step explanation:
The question talks about chosing 5 presenters out of 8 presenter.
This can be achieved b using the following formula:
nCr = n! /r! (n–r)!
n = 8
r = 5
8C5 = 8! / 5! (8 – 5)!
8C5 = 8! / 5! 3!
8C5 = (8 x 7 x 6) / (3 x 2 x 1)
8C5 = 56
Therefore, there are 56 ways in which the teacher can chose the presenters.

I believe the answer is 6
Step-by-step explanation:
Answer:
sqrt(545)
Step-by-step explanation:
The distance between 2 points can be found by
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (6--10)^2 + (8--9)^2)
sqrt( (6+10)^2 + (8+9)^2)
sqrt( (16)^2 + (17)^2)
sqrt( 256+289)
sqrt(545)
