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 zinc.

And we're done.

Thanks for watching buddy good luck.

IgorLugansk [536]

Answer:

$\sf 36x^2 -24x +4$

solving step wise:

$\sf (6x-2)^2$

$\sf (6x-2)(6x-2)$

$\sf 36x^2 -12x -12x +4$

$\sf 36x^2 -24x +4$

$\sf (6x-2)^2$

$\sf (6x)^2 +2*6x*-2+(-2)^2$

$36x^2 -24x +4$

A pail holds 6 3 4 gallons of water. How much is this in cups? Write your answer as a whole number or a mixed number in simplest

storchak [24]

I'm assuming the pail holds 6 3/4 (not 634) gallons of water.

1 gallon= 16 cups

Multiply total gallons by cups per 1 gallon.

= 6 3/4 cups * 16 cups/gallon
convert mixed number to improper fraction

= 27/4 * 16
multiply numerators

= (27*16)/4
multiply in parentheses

= 432/4

= 108 cups

ANSWER: There are 108 cups

Hope this helps! :)
