Answer: The correct option is A, itis the product of the initial population and the growth factor after h hours.
Explanation:
From the given information,
Initial population = 1000
Increasing rate or growth rate = 30% every hour.
No of population increase in every hour is,

Total population after h hours is,

It is in the form of,

Where
is the initial population, r is increasing rate, t is time and [tex(1+r)^t[/tex] is the growth factor after time t.
In the above equation 1000 is the initial population and
is the growth factor after h hours. So the equation is product of of the initial population and the growth factor after h hours.
Therefore, the correct option is A, itis the product of the initial population and the growth factor after h hours.
Answer:
1/10 or 10%
Step-by-step explanation:
1/4 x 2/5 = 1/10 (10%)
There is a lot to go over here. Unfortunately it looks like you got a lot incorrect. I'll focus on two problems. Hopefully these examples below will help correct the other mistakes.
---------------------------------------------------------
Problem 7)
We have the starting value be 20 and the ending value be 11. Subtract the values: (end)-(start) = 11 - 20 = -9. The negative indicates we have a drop or decrease.
We'll focus on the positive version of this number, so 9. Divide this value over the starting amount 20 to get 9/20 = 0.45 = 45%
So going from 20 miles to 11 miles is a decrease of 45%
Answer to problem 7 is: 45%
---------------------------------------------------------
Problem 13)
An increase of 300% means we added 3 times the original amount onto the original amount.
We take 300% of 25 to get 3*25 = 75
Which is then added onto 25 to get 25+75 = 100
Answer to problem 13 is: 100
Answer:
-6.67 im pretty sure
Step-by-step explanation:
4+5=9
9-6=3
3/7=0.43
0.43-7=-6.67
the calculator says sum else but like who cares right? lol
Answer:
IT is 41.5 heres the steps
Step-by-step explanation:
first step 21 divided by 2 = 10.5
Then you do 10.5 + 1 = 11.5
then you do 11.5 times 5 = 57.5
Then 2 times 2 times 2 times 2= 16
then 16 - 57.5 = 41.5 is your answer
