Answer:

Step-by-step explanation:
Initial number of sick wolves = W(0) = 10
At time t, no. of sick wolves = W(t)
Given that disease is spreading at a rate proportional to the product of the time elapsed and the square root of the number of sick wolves:

Mathematical model of above case is:

Answer:
9/22
Step-by-step explanation:
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
−9/4 ÷ −11/2
Applying the fractions formula for division,
=−9×2 divided by 4×−11
=−18/−44
Simplifying -18/-44, the answer is
=9/22
Answer:
thx
Step-by-step explanation:
30 is 1.5 times greater than 20 so 48*1.5 = 72
it would take 72 chicken fingers to feed 30 students
Let a and b be store A and store B, respectively. Then:
3a+b=63
5a+4b=140
So
12a+4b=252
5a+4b=140
7a=112
a=16
b=15
