Answer:

59/20

Step-by-step explanation:

Okay so when we see a decimal after a number we can set that number over 100. So we have 95/100

Then we simplify by dividing by 5 and we end up with 19/20

Have a nice day!

With 19/20 and 2/1, you have to find a common denominator. To do so, you multiply 2/1 time 20/20 to get 40/20.

Then you add your two fractions

19/20 + 40/20

59/20

Answer:

6.5 seconds

Step-by-step explanation:

Keep in mind that when $h=0$ , this is the same height for both when the model rocket takes off and lands, so when the rocket lands, time is positive. Thus:

$h=-4t^2+24t+13\\\\0=-4t^2+24t+13\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-24\pm\sqrt{24^2-4(-4)(13)}}{2(-4)}\\ \\t=\frac{-24\pm\sqrt{576+208}}{-8}\\\\t=\frac{-24\pm\sqrt{576+208}}{-8}\\\\t=\frac{-24\pm\sqrt{784}}{-8}\\\\t=\frac{-24\pm28}{-8}\\\\t=\frac{-24-28}{-8}\\ \\t=\frac{-52}{-8}\\ \\t=\frac{52}{8}\\\\t=6.5$
