Answer:

People\ per\ square\ mile\approx 27539

Step-by-step explanation:

World's Population=7.4\ billion=7.4\times 10^9=7400000000

Area of state=268712\ square\ miles

People\ per\ square\ mile=\frac{total\ population\ in\ that\ area}{total\ area\ of\ the\ state}\\\\Here\ world's\ population\ is\ put\ in\ that\ state\\\\ So\ population\ in\ that\ state=7.4\ billion\\\\People\ per\ square\ mile=\frac{7400000000}{268712}\\\\People\ per\ square\ mile=27538.77\approx 27539

Mai is riding her bicycle. She takes 6 hours to ride 38.4 kilometers. What is her speed?
Kisachek [45]
For the answer to the question What is the speed of Mai if she <span>is riding her bicycle and she takes 6 hours to ride 38.4 kilometers.
I'll provide a solution to my answer below.

</span>time = 6hours

Distance = 38.4 Km

Speed = distance /time
 
           = 38.4/6 
       
           = 6.4 km/h

I hope my answer helped you.

Solve each polynomial equation.
spayn [35]

Answers:

15) x = 8, \frac{1}{3}, - \frac{2}{5}

16) x = 9, \frac{5+\sqrt{17}} {2}, \frac{5 -\sqrt{17}} {2}

17) x = 6, -\frac{3+i\sqrt{11}} {10}, -\frac{3-i\sqrt{11}} {10}

<u>Step-by-step explanation:</u>

15x³ - 119x² - 10x + 16 = 0

\frac{p}{q}: \frac{16}{15}:+/- \frac{1*2*4*8*16}{1*3*5*15}

So, the possible rational roots are: +/-   1, 2, 4, 8, 16,\frac{1}{3},\frac{2}{3},\frac{4}{3},\frac{8}{3},\frac{16}{3},\frac{1}{5},\frac{2}{5},\frac{4}{5},\frac{8}{5},\frac{16}{5},\frac{1}{15},\frac{2}{15},\frac{4}{15},\frac{8}{15},\frac{16}{15}

Use synthetic division with each one until you find a remainder of zero.  I am not going to go through each one because it is too time consuming, however, the first one that works is x = 8

(x - 8)(15x² + x - 2)    

Next, factor 15x² + x - 2 using any method

(x - 8)(3x - 1)(5x + 2)

Now, solve for x.

x = 8, x = \frac{1}{3}, x = -\frac{2}{5}

For #16 & 17, follow the same process as above.

Explain how you can find the measure of angle 12?<br> How can you find the measure of angle 1?
nalin [4]

Let's say you know the measure of angle 10. Let's make it 120 degrees.

Since it looks like you're going through a traversals unit (or something that includes traversals), you know that angle 10 and angle 8 are the same, which means they are both 120 degrees.

Now, since a line is 180 degrees on one side, you have to subtract 180-120 to find angle 7, which is 60.

Using the exterior-interior rule (I don't know the name), you know that angle 7 is equal to angle 1, which gets you 60.

Angle 1: 60 degrees.

You can do the same thing with another angle to find 12, or continue with this scenario with angle 10 being 120 degrees.

Edit: If you want to continue with this scenario, you can use the two interior angle rule, where angle 9 is equal to angle 1, and angle 12 is equal to angle 5. This also means angle 13 is equal to angle 8. But, since angle 13 is also 120 degrees, and there are 180 degrees in a line, that means angle 12 is also 60 degrees.

Angle 12: 60 degrees.
