Hi,
Not sure what exactly you want but the answer is 550.

You can compensate by subtracting 3 from 823 and subtracting 3 from 273 and after doing 820-270 you get 550.

Hope this helps!

Marymount Township secured the construction of a power plant, which opened in 1990. Once the power plant opened

Aleksandr [31]

Answer:

92087,14873

Step-by-step explanation:

Given that Marymount Township secured the construction of a power plant, which opened in 1990. Once the power plant opened in 1990, the population of Marymount increased by about 20% each year for the first ten years and then increased by 5% each year after that

Let P0 be the population in 1990

Then we have in 2000 the population is

$P(2000) = P_0(1.2)^{10}$

with this initial population for next growth we have in 2010 the population would be

$P(1.05)^{10}$ , where P = population is 2000

a) Given that $P(1.05)^{10) = 150000\\P = 150000(1.05)^{-10} =92.086.99\\=92087$

b) we use the exponential equation and solve for initial population in 2000.

c) we have

$P_0(1.2)^{10} =92087\\P_0 = 92087((1.2)^{-10})\\=14872.56\\=14873$

Answer:

zero

Step-by-step explanation:

Dividing the second equation by -3, it becomes ...

x -3y = 7/3

Compared to the first equation, ...

x -3y = 5

we see that it is <em>inconsistent</em>. No values of the variables can satisfy both equations. There are no solutions.

blagie [28]

Answer:

Carlota is not correct

Step-by-step explanation:

A ratio represents relationship between of two or more things.

Ratio of minutes to gallons of water flowing through a garden hose $=2:12$

Here,

$2:12=1:6$

Also,

It's given that an equivalent ratio of minutes to gallons is $6:1$

Now,

$1:6\neq 6:1$

Therefore,

Carlota is not correct
