Question

Determine a razão entre as medidas dos segmentos AB e CD, nessa ordem, considerando:
a)_ AB = 10 cm e CD = 30 cm;

b)_ AB = 7,5 cm e CD = 15 cm;

c)_ AB = 1 cm e CD = 0,5 cm;

d)_ AB = 15 cm e CD = 40 cm;

e)_ AB = 10 cm e CD = 1,5 cm;

f)_ AB = 2√2 cm e CD = 4√2 cm;

Answer 1

Explicação passo-a-passo:

a) $\sf \dfrac{\overline{AB}}{\overline{CD}}=\dfrac{10}{30}=\dfrac{1}{3}$

b) $\sf \dfrac{\overline{AB}}{\overline{CD}}=\dfrac{7,5}{15}=\dfrac{1}{2}$

c) $\sf \dfrac{\overline{AB}}{\overline{CD}}=\dfrac{1}{0,5}=2$

d) $\sf \dfrac{\overline{AB}}{\overline{CD}}=\dfrac{15}{40}=\dfrac{3}{8}$

e) $\sf \dfrac{\overline{AB}}{\overline{CD}}=\dfrac{10}{1,5}=\dfrac{20}{3}$

f) $\sf \dfrac{\overline{AB}}{\overline{CD}}=\dfrac{2\sqrt{2}}{4\sqrt{2}}=\dfrac{1}{2}$
