Answer:
21 child tickets
Step-by-step explanation:
For this problem, you'd use a system of equations.
First, define your variables.
x = # of child tickets sold
y = # of adult tickets sold
There were 4 times as many adult tickets (y) as child tickets (x) sold, so:
4 x = y
4 x - y = 0
93 (4 x - y = 0)
372 x - 93 y = 0
The total revenue was $909.30, adult tickets were $9.30 each, child tickets were $6.10 each, so:
6.10 x + 9.30 y = 909.30
10 (6.10 x + 9.30 y = 909.30)
61 x + 93 y = 9093
372 x - 93 y = 0
433 x = 9093
433 x / 433 = 9093 / 433
x = 21
Answer:
a ║ c
b ║ f
Step-by-step explanation:
when parallel lines are cut by a transversal line, the supplementary angles are angles whose angle measure adds up to 180°
so answers are:
a ║ c
b ║ f

For permutation P we will use:
nPr = n!/(n-r)!
7P5 = ?
n = 7
r = 5
7P5 = 7!/(7-5)!
= (7 * 6 * 5 * 4 * 3 * 2 * 1)/2!
= 5040/(1 * 2)
= 5040/2
= 2520
