(04.01)The Baldwin family walked 4/5 of a mile in 4/9 of an hour. What is their unit rate in miles per hour?
sertanlavr [38]
Hello!

Since we know how much they walked in 4/9 of an hour, we will divide 4/5 by 4/9 to get 4/9 to one.

\frac{4}{5}÷\frac{4}{9}=\frac{36}{20} =  \frac{9}{5}

They went 1 4/5 mph or 1.8 mph.

I hope this helps!

Solve x^2+2x+7=0 using the quadratic formula.
Aneli [31]

Answer:

x=-1\pm \sqrt{6}i

Step-by-step explanation:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\frac{-(2)\pm\sqrt{2^2-4(1)(7)}}{2(1)}

x=\frac{-2\pm\sqrt{4-28}}{2}

x=\frac{-2\pm\sqrt{-24}}{2}

x=\frac{-2\pm\sqrt{-1*24}}{2}

x=\frac{-2\pm\sqrt{-1}\sqrt{24}}{2}

x=\frac{-2\pm i\sqrt{4*6}}{2}

x=\frac{-2\pm i\sqrt{4}\sqrt{6}}{2}

x=\frac{-2\pm2i\sqrt{6}}{2}

x=-1\pm \sqrt{6}i
