<span>Formula : V + F – E = 2
where V = number if vertices, F = number of faces and E = number of edges
<u>Question a:</u>
V + F - E = 2
V = 2 - F + E
V = 2 - 12 + 18
V = 8
(a) </span><span>12 faces, 18 edges, <u>8</u> vertices
<u>Question b:</u>
</span>V + F - E = 2
<span>E = V+ F - 2
E = 14 + 8 - 2
E = 20
(b) </span><span>8 faces, <u>20</u> edges, 14 vertices</span>
Answer: Equilateral, C
Reasons:
1. The angles aren't right
2. All of the sides are the same length
The answer is that each person will be paying $16.75 if the bill is equally divided. Hope this helps! Plz mark me brainliest!! :)
Answer:
They arrive at the same time.
Step-by-step explanation:
If Alison spends 3 seconds to cover the last 1/4, it means that in 12 seconds will cover the four quarters because the acceleration is constant.
On the other hand Kevin spends 4 seconds to cover the last 1/3 of the distance, it means that in 12 seconds will cover three thrds.
Finally we can conclude that both of them spend the same time to cover the drag race.
