A study show that there are 16 vehicles for every 10 households how many vehicles are there for 107 million households
Lisa [10]
\bf \begin{array}{ccll}&#10;vehicles&households\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;16&10\\&#10;v&107E6&#10;\end{array}\implies \cfrac{16}{v}=\cfrac{10}{17E6}\implies \cfrac{17E6\cdot 16}{10}=v

just to clarify the engineering notation, E6 is just 1 and 6 zeros, or a million, thus, 107,000,000 is just 107E6.

Answer:

  D.  Minimum at (3, 7)

Step-by-step explanation:

We can add and subtract the square of half the x-coefficient:

  y = x^2 -6x +(-6/2)^2 +16 -(-6/2)^2

  y = (x -3)^2 +7 . . . . . simplify to vertex form

Comparing this to the vertex for for vertex (h, k) ...

  y = (x -h)^2 +k

We find the vertex to be ...

  (3, 7) . . . . vertex

The coefficient of x^2 is positive (+1), so the parabola opens upward and the vertex is a minimum.

Answer: x=4.7434

Step-by-step explanation:

Use the pythagorean theorem a^{2} +b^{2} =c^{2}

plug in and solve

x^{2} +3x^{2} =(3\sqrt{10}) ^{2}

4x^{2} =90

x^{2} =22.5

x=4.7424

if you need to solve for the sides

3x = 3(4.7434) = 14.2302

55.27 is the same as 55 ____' 12".
choli [55]
<span><span>27100</span>(60)=<span>815</span>=16<span>15</span></span> The 16 is how many minutes you have. If you were not given the seconds, we would have to say that we have a remainder of (1/5) of a minute. Since 1 minute is (1/60), one-fifth of that is (1/300). Now we would need to see how many seconds that gives us. 1 second is (1/3600) of a degree, so we would need to divide (1/300) by (1/3600). Doing this gives us: <span><span><span>1300</span>÷<span>13600</span>=<span>1300</span>(3600)=12</span></span>
