r Flag For Review A certain city with a population of 132,000 is to be divided into 11 voting districts, and no district is to h

Alex787 [66]

Answer:

$P = \frac{132000}{12}=11000$

So then P =11000 is the minimum that the least populated district could have.

Step-by-step explanation:

We have a big total of N = 132000 for the population.

And we know that we divide this population into 11 districts

And we have this info given "no district is to have a population that is more than 10 percent greater than the population of any other district"

Let's assume that P represent our minimum value for a district in the population. The range of possible values for the population of each district would be between P and 1.1 P

The interest on this case is find the minimum value for P and in order to do this we can assume that 1 district present the minimum and the other 10 the maximum value 1.1P in order to find which value of P satisfy this condition, and we have this:

$P + 10 (1.1P) = 12 P= 132000$

$P = \frac{132000}{12}=11000$

So then P =11000 is the minimum that the least populated district could have.

Identificati,prin verificare,ecuatia pentru care numarul x=3 este solutia

elena-s [515]

Answer:

concluzionăm că nu există o ecuație care să poată justifica valoarea x = 3 din opțiunile de mai sus după rezolvarea lor

Step-by-step explanation:

Urmează să aflăm din cele trei opțiuni date, care este una dintre opțiuni care rezultă în x = 3

Să rezolvăm opțiunea una după cealaltă pentru a deduce și determina care este răspunsul corect și corect.

a) $-2*x + 3 = 9$

$-2x = 9 -3$

$-2x = 6$

Împărțiți ambele părți la -2

x = 6/-2

x = -3

b) $-4*x +5 = 7$

$-4x = 7 -5$

$-4x = 2$

Împărțiți ambele părți la -4

$x = \dfrac{2}{-4} \\ \\ \\ x= \dfrac{1}{-2}$

c) $\dfrac{1}{3}*x -8 =9$

$\dfrac{1}{3}x = 9 +8$

$\dfrac{1}{3}x =17$

Înmulțiți ambele părți cu 3

$x =17*3$

x = 51

Prin urmare; concluzionăm că nu există o ecuație care să justifice valoarea x = 3 din opțiunile de mai sus după rezolvarea lor

Answer:

$\boxed{\sf \ \ \ 11,464 \ \ \ }$

Step-by-step explanation:

hello

we need to compute the following

$\sum\limits^9_{i=0} {1000(1.03)^i}=1000\dfrac{1.03^{10}-1}{1.03-1}=11463.879...$

Micah rows his boat on a river 4.48 miles downstream, with the current, in 0.32 hours. He rows back upstream the same distance,

Molodets [167]

Let the speed of the current be y and the speed of Micah's sailing speed be x. Then 4.48/(x + y) = 0.32
4.48/(x - y) = 0.56

0.32x + 0.32y = 4.48 . . . (1)
0.56x - 0.56y = 4.48 . . . (2)
(1) x 7 => 2.24x + 2.24y = 31.36 . . . (3)
(2) x 4 => 2.24x - 2.24y = 17.92 . . . (4)
(3) - (4) => 4.48y = 13.44
y = 3
From (1), 0.32x + 0.32(3) = 4.48
0.32x = 4.48 - 0.96 = 3.52
x = 3.52/0.32 = 11

Therefore, the speed of the current is 3 miles per hour.
