Answer:
Approximately after 66.15 years, there will be 100 coyotes left
Step-by-step explanation:
We can use the formula to solve this.
Where
F is the future amount (F=100 coyotes)
P is the initial amount (P=750 coyotes)
r is the rate of decrease per year (which is -3% per year or -0.03)
t is the time in years (which we need to find)
Putting all the information into the formula we solve.
<u>Note:</u> The logarithm formula we will use over here is
So, we have:
Hence, after approximately 66.15 years, there will be 100 coyotes left.
Rounding, we will have 66 years

Answer: There are 8 snake and 3 elephants.
Step-by-step explanation:
Let x= Number of snakes
y= Number of elephants
We know that , snake has no legs elephant has 4 legs.
Then, Total animals = x+y=11 (i)
Total legs = 4y = 12
⇒ y=3 .. (ii)[divide both sides by 4]
Substitute value of y from (ii) in (i) , we get
Hence, there are 8 snake and 3 elephants.
Answer:
4
Step-by-step explanation:
20 x 4 = 80
so 1 per 20 minuets,and 4, 20 min. magazines would mean he needs 4 to make it to 80
