√2 is irrational

a rational number Q can be expressed in the form $\frac{a}{b}$ where a and b are integers.

- 18 = $\frac{- 18}{1}$ ⇒ rational

$\frac{2}{3}$ ⇒ rational

3.14 = $\frac{314}{100}$ ⇒ rational

√2 = 1.414213562...... ⇒ irrational

dezoksy [38]

Answer:

let's see what to do buddy...

Step-by-step explanation:

$\frac{zinc}{copper} = \frac{3}{17} \\ \\ \frac{zinc}{799} = \frac{3}{17}$

Multiply the sides of the equation by 799

$zinc = \frac{3}{17} \times 799 \\ \\ zinc = \frac{3}{17} \times 17 \times 47 \\ \\ zinc = 3 \times 47 = 141$

So A jar of the chemical contains 141 grams of <em><u>zinc</u></em>.

And we're done.

Thanks for watching buddy good luck.
