Step-by-step explanation:
x=180
y=160
0.4(x+y)+42 =
0.4(180 + 160) +42 =
0.4(340)+42=
136+42=
178cm
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.
That is a fraction but if you want it simplified
i believe 999/1000
