5) Assim como as figuras geométricas, os objetos do dia a dia também
podem ser classificados segundo suas dimensões. Identifique os objetos abaixo
que lembram regiões planas (P),
sólidos geométricos (S) e ou os que
lembram contornos (C).

<!--[if !supportLists]-->a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Linhas laterais de um campo de futebol.

<!--[if !supportLists]-->b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Cédula de dinheiro.

<!--[if !supportLists]-->c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Folha de cartolina.

<!--[if !supportLists]-->d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Caixa de creme dental.

<!--[if !supportLists]-->e)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Seu quarto.



6) O dono de um canil vacinou todos os seus cães, sendo 80% contra parvovirose
e 60% contra cinomose. O percentual de animais que foram vacinados contra as
duas doenças é de:

<!--[if !supportLists]-->a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->14%&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
b) 22%&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; c) 40%&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; d) 68%&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; e) 140%



7) Faça a comparação dos números correspondentes às situações dadas:

<!--[if !supportLists]-->a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->3,5°C abaixo de zero e 1,3°C acima de zero. 

<!--[if !supportLists]-->b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->0,8m abaixo do nível do mar e 1m abaixo do nível
do mar. 

<!--[if !supportLists]-->c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Saldo positivo de R$ 85,20 e saldo positivo de
R$ 52,10.

<!--[if !supportLists]-->d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Saldo negativo de 5 gols e saldo zero.



8) Desenhe o polígono ABCDE
e responda às questões:

<!--[if !supportLists]-->a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Esse polígono é convexo ou não convexo?

<!--[if !supportLists]-->b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Quantos e quais são seus vértices?

<!--[if !supportLists]-->c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Quantos e quais são seus lados?

<!--[if !supportLists]-->d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Quantos são as diagonais?



9) &nbsp;Calcule o número de diagonais
em:

<!--[if !supportLists]-->a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Um pentágono&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; c) Um hexágono

<!--[if !supportLists]-->b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<!--[endif]-->Um eneágono&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; d) Um
icoságono



&nbsp;10) Juliano colou&nbsp; uma&nbsp;
bandeirinha&nbsp; cinza em cada
engrenagem, como mostra a

figura abaixo:

<!--[if gte vml 1]><v:shape id="_x0000_i1031" type="#_x0000_t75"
 style='width:160.5pt;height:82.5pt' o:ole="" fillcolor="window">

 <o:OLEObject Type="Embed" ProgID="Word.Picture.8" ShapeID="_x0000_i1031"
  DrawAspect="Content" ObjectID="_1532188858">
 
<![endif]-->

As engrenagens são iguais e quando a engrenagem da esquerda girou um
pouco, a sua bandeirinha ficou na posição indicada com a bandeirinha branca
pontilhada. Nesta condição, podemos afirmar que a posição da bandeirinha na
engrenagem da direita é:
