Answer:
A. 
The solution is: n=20
Step-by-step explanation:
1. You have the following information given in the problem above:
- The hitter batted
of the runs the team scored.
- The hitter batted in 5 runs.
2. If
is the number of run the team scored, then
of
must be equal to five runs batted by the hitter. Therefore, the equation is:

3. Solve for
, as following:

Answer:
k and l....................
Answer: Rectangle
If you let
P = (0,0)
Q = (0,b)
R = (a,b)
S = (a,0)
you'll be able to find that
PQ is a vertical line with undefined slope
QR is a horizontal line with slope 0
so PQ and QR form a right angle as they are perpendicular lines
You'll find this with the other line pairings as well. We'll have four right angles
Answer:
The substance half-life is of 4.98 days.
Step-by-step explanation:
Equation for an amount of a decaying substance:
The equation for the amount of a substance that decay exponentially has the following format:

In which k is the decay rate, as a decimal.
k-value of 0.1392.
This means that:

Find the substance's half life, in days.
This is t for which
. So







The substance half-life is of 4.98 days.
