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.

It costs a flat fee of $3.15 to make an international call plus $0.05 for every minute that you talk. if you were charged $5.10

DerKrebs [107]

The equation would be 0.05x + 3.15 = 5.10
0.05x = 1.95 (subtraction)
x = 39 (division)

Walking lights are placed around the perimeter of rectangular garden 30 feet be 16 feet and are placed 18 inches apart. How many

Masteriza [31]

Well we can find the perimeter by using the formula P=2L + 2W
P=2(30) + 2(18) P=60+36 P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed.
96÷18=5.333333
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)

At noon of a certain day, when 5 pens and 3 pencils were placed in a drawer, the ratio of the number of pens to the number of pe

Molodets [167]

The question is probably incomplete. What i am assuming is that the person might ask for the previous ratio or the total number of pens and pencil in the drawer.

So if it is the previous ratio it obviously would be 47 - 5 : 17 -3 so 42 : 14 and in case he or she is asking for the total number of pens and pencils in the drawer before so they were 42 + 14 hence 56.
