Answer: 5 faces,8 edges,5 vertices
Step-by-step explanation:5 faces - of which 1 is a square face at the base and 4 isosceles triangle, above.
5 vertices - of which 4 are at the base where 3 edges meet and one above where 4 edges meet.
8 edges - of which 4 are equal in length and at the base and the other 4 are equal in length and above.
Answer:
7
Step-by-step explanation:
3p + 4c = 40 ⇒ 15p + 20c = 200
5p + 2c = 34 ⇒ 15p + 6c = 102
14c = 98
14 14
c = 7
5p + 2(7) = 34
5p + 14 = 34
- 14 - 14
5p = 20
5 5
p = 4
(p, c) = (4, 7)
You do 16 kids that choose art, over 40 kids that choose swimming, to get 16/40, simplified it becomes 2/5 children.
