The number of $5 notes is 10 and $50 notes is 6
Step-by-step explanation:
Let x be the number of $5 notes
and
y be the number of $50 notes
Then according to given statements
"The total number of notes used was 16."
x+y=16 Eqn 1
"A restaurant bill of $350 was paid using $5 notes and $50 notes."
5x+50y=350 Eqn 2

Putting x=10 in equation 1

So,
The number of $5 notes is 10 and $50 notes is 6

Answers:
- a. Quadrant II
- b. negative
- c.

- d. C
- e.

<u>Explanation:</u>

a) Quadrant 2 is: 
b) In Quadrant 2, cos is negative and sin is positive, so tan is negative
c)
= 
d) the reference line is above the x-axis so it is negative --> 
e) 
Answer:
C = 56.6
Step-by-step explanation:
Circumference Formula: C = 2πr
Simply plug in <em>r</em> into your formula
C = 2π(9)
C = 18π or 56.556
