Answer:
180
Step-by-step explanation:
An application of the nonlinear system of differential equations in mathematical biology/ecology: to model the predator-prey relationship of a simple eco-system. ... They form a simple food-chain where the predator species hunts the prey species, while the prey grazes vegetation.
3 yards = 36*3 = 108 inches
-> total of width and length = 108/2 = 54 inches, because perimeter = 2*total of length and width.
=> length + width = 54 inches
and 6 ≤ width <span>≤ 12
=> all possible dimensions are:
6x48
7x47
8x46
9x45
10x44
11x43
12x42</span>
Answer:
1.5 for how far he ran in 4 seconds
Step-by-step explanation:
The formula for finding the circumference of a circle is 
(where d is the diameter). So, simply plugging in 622 mm for <em>d </em>and 3.14 for pi, we find that c = 622 * 3.14 = 1953.08 mm.
