Answer:
2390.7 square meters
Step-by-step explanation:
(semicircle area) 30.5/2 = 15.4
15.4 x 15.4
= 232.5625 x 3.14
= 730.24625 x 2 = 1460.4
(square area) 30.5 x 30.5 = 930.25
930.25+ 1460.4= 2390.7 square meters

Answer:
44.7 mg
Step-by-step explanation:
The equation for exponential decay can be written in the form ...
y = a·b^(t/p)
where 'a' is the initial value, 'b' is the decay factor, 'p' is the period over which the decay factor is applicable, and t is time in the same units as p.
<h3>Setup</h3>
Using the above equation, we have ...
a = initial value = 110 mg
b = decay factor = 55/110 = 1/2 over time period p=20 hours
Then the equation is ...
y = 110·(1/2)^(t/20) . . . . amount remaining after t hours
<h3>Solution</h3>
We want the amount remaining after 26 hours. That will be ...
y = 110·(1/2)^(26/20) ≈ 44.67
About 44.7 milligrams will remain after 26 hours.
