Answer:

Faces~:~5\\Edges~:~8\\Vertices~:~5

Concept:

Here, we need to distinguish between face, edge, and vertex (plural: vertices)

A face is a single flat surface

An edge is a line segment between faces

A vertex is a corner

<em>Please refer to the attachment below for a visual understanding</em>

Solve:

<u>Count the number of faces</u>

  • One on the bottom
  • Four connecting to each side of the square at the bottom

1 + 4 = \Large\boxed{5~faces}

<u>Count the number of edges</u>

  • Four on the bottom that shape the square
  • Four on the sides that shape the triangles

4 + 4 = \Large\boxed{8~edges}

<u>Count the number of vertices</u>

  • Four on the bottom that surrounds the square
  • One on the top where triangles intersect

4 + 1 = \Large\boxed{5~vertices}

Hope this helps!! :)

A car travelled 100 km with half the distance at 40 km/h and the other half at 80 km/h. Find the average speed of the car for th
Nana76 [90]
We must look at this question in steps
The first half of the journey is travelled at 40 km/h
Half of 100km is 50 km
Using the formula
Distance = Speed x Time
Speed = Distance / Time
Time = Distance / Speed
We can work out the time:

50km / 40km/h = 1.25 hours

Next we look at the second half of the journey
50km at 80km/h
50km / 80km/h = 0.625 hours

Add together both times to work out how long the entire journey took
1.25 + 0.625 = 1.875 hours

Using the Speed formula from before
Speed = 100km / 1.875 =
53 1/3 km/h or 53.3 recurring km/h

In the function y = 10.00x + 35, y represents the cost of cabin lodging per occupant and x represents the number of occupants. H
UkoKoshka [18]
Y = 10x + 35

if y is cost per occupant and x is occupants, then we can read the equation as such:

Cost is equal to 10 times number of occupants plus a 35$ fee

10 times the number of occupants is the part we are worried about

The cost increases by 10$ for every occupant
