The jar has 138 grams of zinc.
<u>Solution:</u>
Given that , In a certain chemical reaction, the ratio of zinc to copper is 3 to 16.
A jar of the chemical contains 736 grams of copper.
We have to find how many grams of zinc does it contain
Let "n" be the grams of zinc needed for 736 grams of copper
Now, we know that,
16 grams of copper ⇒ 3 grams of zinc
Then, 736 grams of copper ⇒ n grams of zinc
So, by criss cross multiplication,
16n = 3 x 736
16n = 2208
n = 138
Hence, the jar has 138 grams of zinc.
The ordered pairs of the points F, G and H are their locations on the coordinate plane
The point F is above the line 1
<h3>How to determine the coordinate point?</h3>
The ordered pairs of the points are given as:
F = (0,7)
G = (6, 2)
H = (1,6)
The line is not given; so, I will provide a general explanation.
Of all the three ordered pairs, the point with the greatest y-coordinate is the point F.
This means that the point F can be above the line 1, while the other points G and H are below the line.
See attachment for the illustration of the line and the ordered pairs
