A city of 6,688 has an area of 16 square miles. What is the population density of the city?
Ahat [919]
To find population density, it is population / area.

The population is 6688, divided by the area of 16.

6688/16 = 418

So the population density is 418 people per sq mile.

Any clue on this one please help
barxatty [35]

Yes, because they both have the same slope, and a translation doesn't have an affect of the slope. Both slopes are 1, because they are going +1x and +1y, or 1/1 which = 1.

If the pressure in the tank is 1.5 bar and atmospheric pressure is 1 bar, determine l, in m, for water with a density of 997
il63 [147K]

this can be solve using the formulaP = rghwhere P is the total pressurer is the densityh is the heightg is the acceleration due to gravity
fist solve the total pressureP = 1.5 bar + 1 barP = 2.5 barP = 250,000 Pa
P = rgh250,000 = (997)(9.81)hh =25.56 m

-2x = 16–8y<br> x+4y= 25<br> Solve by substitution
ra1l [238]

Answer:

(\frac{17}{2}, \frac{33}{8}

Step-by-step explanation:

Given the 2 equations

- 2x = 16 - 8y → (1)

x + 4y = 25 → (2)

Rearrange (2) expressing x in terms of y by subtracting 4y from both sides

x = 25 - 4y → (3)

Substitute x = 25 - 4y into (1)

- 2 (25 - 4y) = 16 - 8y ← distribute left side

- 50 + 8y = 16 - 8y ( add 8y to both sides )

- 50 + 16y = 16 ( add 50 to both sides )

16y = 66 ( divide both sides by 16 )

y = \frac{66}{16} = \frac{33}{8}

Substitute this value into (3) for corresponding value of x

x = 25 - 4 × \frac{33}{8} )

  = \frac{50}{2} - \frac{33}{2} = \frac{17}{2}

Solution is ( \frac{17}{2}, \frac{33}{8} )
