Eulerian Path is a path in graph that visits every edge exactly once.
For part (a) the answer is 400 grams for part (b) 198.63 grams and for part (c) 20 years.
<h3>What is exponential decay?</h3>
During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
We have an equation for radioactive decay:

a) Plug t = 0

m(0) = 400 grams
b) plug t = 20 years

After solving:
m(20) = 198.63 grams
c) Plug m(t) = m(0)/2 = 400/2 = 200 grams

x = 19.80 years ≈ 20 years
Thus, for part (a) the answer is 400 grams for part (b) 198.63 grams and for part (c) 20 years.

Volume of a rectangular prism(the baseball card case) can be defined as follows: V = lwh
V = lwh
V = 12(6.5)(1.25)
V = 97.5 cm³
If

, then any ordered pair would satisfy the equation.
Since we're not given the ordered pairs, then this is the only information I can give to you.
