√2 is irrational

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

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.
