Answer:
$9.10
Step-by-step explanation:

455 ÷ 50 = 9.1. The student tickets cost $9.10. (I think)
Answer:$0.85
Step-by-step explanation:
.95x17= 16.15 17.00-16.15=0.85
The rate of change in z at (4,9) as we change x but hold y fixed is =
3/[2sqrt(3x+2y)] put x = 4 , y = 9 = 3/[2sqrt(12+18) = 3/[2sqrt(30)] The
rate of change in z at (4,9) as we change y but hold x fixed is =
1/sqrt(3x+2y) put x = 4, y =9 = 1/sqrt(30)
Here, exterior angles are 1, 2, 7 & 8 as they are outside the parallel lines, & among them, alternates are: 1 with 7 and 2 & 8. 1 & 7 is not in option but 2 and 8 is there in C
In short, Your Answer would be Option C
Hope this helps!
