Answer:
Euler's Formula states that:
V -E +F = 2 meaning that the vertices minus the edges plus the faces of a convex polyhedron will always equal two.
So, for the initial question, we have 40 edges and 24 faces.
So, vertices = 2 + Edges -Faces
Vertices = 2 + 40 - 24
Vertices = 18

Answer:
y=12/x
Step-by-step explanation:
if y=12, and x=1 so
general formula y=12/x
for x=5 , y=12/5=2.4
you can graph by ploting points such as (1,12), (5, 2.4),...
$0.85 * 4 = $3.40
$6.40 - $3.40 = $300
Brussel sprouts per pound = $300 / 4
= $0.75
In the top the "f(x)" equals 9, now they are asking you to add onto the 9 by 1 causing it to be 10. If you did the first few you would have noticed that it takes 9 in order to get to 5 from -4.
here are the answers btw:
8pm to 2am, or 8am to 2pm, either way, Carla would've worked for 6 hours.
6*$13=$78
-----------
Carla would earn $78 if she were to clean for 6 hours.
