A bag contains green marbles and red marbles, 36 in total. The number of green marbles is 1 more than 4 times the number of red

tatuchka [14]

Answer:

Step-by-step explanation:

Total marble = 36

Let red marbles be X

Then green marble is 4X + 1

And 4X + 1 + X = 36

5X = 36 - 1

5X = 35

X = 35/5 = 7

So, green marbles = 4X + 1

= 4(7) + 1

= 29

Answer:

$\large \boxed{\textbf{30.54 yr}}$

Step-by-step explanation:

For species A,

$P =2000e^{0.05t}$

For species B,

$P =5000e^{0.02t}$

When their populations are equal,

$\begin{array}{rcl}2000e^{0.05t} & = & 5000e^{0.02t}\\e^{0.05t} & = & 2.5e^{0.02t}\\0.05t & = & \ln2.5 + 0.02t\\0.05t & = & 0.9163 + 0.02t\\0.03t & = & 0.9163\\t& = & \dfrac{0.9163}{0.03}\\\\& = & \mathbf{30.54}\\\end{array}\\\text{The populations of species A and B will be the same in $\large \boxed{\textbf{30.54 yr}}$}$

The diagram below shows the population of Species A overtaking that of Species B in about 30.5 yr.
