Noah is running a portion of a marathon at a constant speed of 6 mph. Complete the table to predict how long it would take him t
ycow [4]

Answer:

\begin{array}{cc}\text{Time}&\text{Distance}\\ \\1&6\\ \\\dfrac{1}{2}&3\\ \\1\dfrac{1}{3}&8\\ \\1\dfrac{1}{2}&9\\ \\9&54\\ \\4\dfrac{1}{2}&27\end{array}

Step-by-step explanation:

Noah's running speed = 6 mph.

Use formula D=v\cdot t, where

D is the distance,

v is the speed,

t is the time.

If t=1 hour, then D=6\cdot 1=6 miles.

If t=\dfrac{1}{2} hour, then D=6\cdot \dfrac{1}{2}=3 miles.

If t=1\dfrac{1}{3} hours, then D=6\cdot 1\dfrac{1}{3}=6\cdot \dfrac{4}{3}=8 miles.

If t=1\dfrac{1}{2} hours, then D=6\cdot 1\dfrac{1}{2}=6\cdot \dfrac{3}{2}=9 miles.

If t=9 hours, then D=6\cdot 9=54 miles.

If t=4\dfrac{1}{2} hours, then D=6\cdot 4\dfrac{1}{2}=6\cdot \dfrac{9}{2}=27 miles.

So, the table is

\begin{array}{cc}\text{Time}&\text{Distance}\\ \\1&6\\ \\\dfrac{1}{2}&3\\ \\1\dfrac{1}{3}&8\\ \\1\dfrac{1}{2}&9\\ \\9&54\\ \\4\dfrac{1}{2}&27\end{array}

10 points for answering!<br> What is the answer to 13, 14, and 15?
ki77a [65]

Step-by-step explanation:

<h2>13. </h2>

\implies\sf{ {x}^{2} = 144 } \\  \\  \implies\sf{ x =  \pm \sqrt{144} }   \\  \\ \implies\sf{ x =  \pm 12 }

<h2>14.</h2>

\implies\sf{ {x}^{2} =  \dfrac{25}{289}  } \\  \\  \implies\sf{ x =  \pm \sqrt{ \frac{25}{289} } }   \\  \\ \implies\sf{ x =  \pm  \frac{5}{17}  }

<h2>15.</h2>

\implies\sf{ {x}^{3} = 216 } \\  \\  \implies\sf{ x =   \sqrt[3]{216}  }   \\  \\ \implies\sf{ x =  6 }
