Ter condições de acessibilidade a espaços e equipamentos urbanos é um direito de todo cidadão. A construção de rampas, nas entradas de edificios que apresentam escadas, garante a acessibilidade principalmente as pessoas com
deficiência física ou com mobilidade reduzida.
Pensando nisso, na entrada de uma ETEC onde há uma escada de dois degraus iguais, cada um com 15 cm de altura, pretende-se
construir uma rampa para garantir a acessibilidade do prédio a todos.
Essa rampa formará com o solo um ângulo de 3º, conforme a figura.

cos 3º = 0,99
Sendo assim, conclui-se que o comprimento da rampa será, em metros,
a) 5
b) 3

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
