Answer:
The population growth is 6.26 per square mile per year
Step-by-step explanation:
We are given
he US Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years
So,
Initial population =128.7
Final Population =191.3
Total time =10 years
now, we can find population grow per year
now, we can plug values
So,
The population growth is 6.26 per square mile per year
The formula of a slope:
We have the points (0, -2) and (6, 0).
Substitute:
<h3>Answer: A. 1/3</h3>
Answer:
15 years old
Step-by-step explanation:
im assuming they're saying to find Ankit's age if his father is 50.
Ankit's father=f, Ankit=a
f=3a +5, f=50: 50=3a+5 -> 3a=45 -> a=15
Answer:
3t +2
Step-by-step explanation:
In order to combine the like terms, you look at the constants and the variables. A variable has a letter in it. When looking at this expression, you find that there are two variables, 4t and -t. You then simplify these variables, getting 3t because it is 4t - t. Now, there is a two left, and since that ISN'T a variable, and is a constant, we can't do anything with it because we cannot combine it with anything else in the expression. Your guess was partially right ;)
Hope this helped!
The equation that would let us determine the number of people or population at a certain year is calculated through the equation,
A(t) = A(o)(2^(t - 1950)/50)
Substituting the known values,
A(t) = (2.5 million people)(2^(2100 - 1950)/50))
A(t) = 20 million
<em>Answer: 20 million people</em>
