Step-by-step explanation: you do 6 time 5 which is 30 and it is a negative times a positive which equals a negative so it is a negative
Answer:
247.12 million
Step-by-step explanation:
Given:
In 1990, population=242 million
In 1999, population=244 million
estimated population in 2013=?
Estimated growth is calculated by:
P(t)= Po*e^(kt)
where Po is original population
k is growth rate
t is the time in year
Now putting the values of Po=242, P(t)=244, t=9 (t=1999-1990=9) we have:
244=242e^(9k)
(244/242)=e^(9k)
ln(244/242)=9k
k=1/9ln(244/242)
k=0.00091
Now Putting k=0.00091, Po=242, and t=23 (t=2013-1990=23) we have:
P(t)=242e^(23*0.00091)
P(t)=247.12 million
the population in 2013 estimated to be 247.12 million!

You would multiply 40 by 10=400
Answer:
The equation relating the number of cars to the number of passengers is p = 4n
Step-by-step explanation:
Given that certain type of car has room for 4 passengers
To find: write an equation relating the number of cars to the number of passengers
Let "n" be the number of cars
Let "p" be the number of passengers
From given information,
Car has room for 4 passengers. Therefore, we can frame,
number of passengers = 4 ( number of cars )
p = 4 (n)
p = 4n
Thus the equation relating the number of cars to the number of passengers is p = 4n
Answer:
120 cubes.
Step-by-step explanation:
If we fill the whole bottom, we get 30 cubes, because the length is 10 and the width is 3.
Then, because it is 4 blocks high, we take 30x4, which is 120.
