the math
Answer:
Surface Area = 86 cm^2
Step-by-step explanation:
Given:
Triangle,
b = 8 cm
h = 9 cm
Rectangle,
l = 10 cm
w = 5 cm
To Find:
Surface Area = ?
Solution:
Surface Area = b x h /2 + l x w
Surface Area = 8 x 9 / 2 + 10 x 5
Surface Area = 4 x 9 + 50
Surface Area = 36 + 50
Therefore, Surface Area = 86 cm^2

<span>Assuming the reaction is of 1st order, we can
start using the formula for rate of 1st order reaction:</span>
dN / dt = k * N
Rearranging,
dN / N = k dt
Where N = amount of sample, k = rate constant, t = time
Integrating the equation from N = Ni to Nf and t = ti to
tf will result in:
ln (Nf / Ni) = k (tf – ti)
Since k is constant, we can equate to situations.
Situation 1 is triple in size every days, situation 2 is after 20 days.
ln (Nf / Ni) / (tf – ti) = k
ln (3Ni / Ni) / 4 = ln (Nf / 40) / 20
Calculating for Nf,
