Answer:
5.66
Step-by-step explanation:
c^2= a^2 plus b^2
c^2 = 16 plus 16
c^2 = 32
c = 5.6568
Answer:
See below.
Step-by-step explanation:
Let “x” be a coach ticket.
Let “y” be a first class ticket.
Let’s set up a system of equations.
120x + 990y = 3210
x + y = 5
120x = 3210 - 990y
x = 26.75 - 8.25y
26.75 - 8.25y + y = 5
- 7.25y = -21.75
y = 3
120x + 990 * 3 = 3210
120x = 240
x = 2
She bought 2 coach tickets and 3 first class tickets.
Slope is found by the formula (y2 -y1) divided by (x2 - x1). We plug in the numbers, and get ((-2) - 2) divided by (6 - (-3)). So the slope will be -0.44
C=pid
d=diameter
d=4
C=4pi
tada
if you want
aprox pi=3.14
C=12.56 units
