A.
The rate is 12:2
B.
Set up a proportion:
12/2 = x/5
Multiply 5 to both sides:
60/2 = x
Divide:
30 = x
So he will walk 30 miles in 5 hours.
C.
To find out, we can divide 12 / 2.
12 / 2 = 6 miles per hour
Answer:
It does not pass the vertical Line test, because the vertical line test is when you put a line through a something like this circle and if it passes throug it more the once it is not a line.
Step-by-step explanation:
Hope this help.
Answer: Y=-1/4x
Step-by-step explanation:
A good way to find an equation of a line is to look for the slope. An obvious spot on this line would be when it crosses (0,0), and another one to the right would be when it crosses at (4,-1).
The slope is rise over run, or if we use the two points we found, "rise" would be -1, because it's dropping 1 unit when going from (0,0) to (4,-1), and the "run" would be 4, because it moves to the right 4 from (0,0) to (4,-1).
Putting these two values together we get:
m (slope) = rise / run
m = -1 / 4
Out of all the equations we're given, we can look for the one with a slope of -1/4, which is given to us:
y = (-1/4)x
There is no given data table but based on the question, the reaction is
xy <=> x + y
If we let M as the initial concentration of xy and c as the in the concentration after the dissociation, then we can use the ICE method
xy <=> x + y
I M
C -c c c
-----------------------------
E M-c c c
Solve for c using
Kc = c(c) / (M - c)
And the concentration of the xy, x, and y can then be determined
