19^2 + x^2 = 21^2

19^2 = 361

21^2= 441

361 + x^2 = 441

x^2 = 441-361 = 80

x = sqrt(80) = 8.944 round to nearest tenth = 8.9

Plz help me plzzzzz asap

Answer:

2 $\frac{2}{9}$

Step-by-step explanation:

First, we will turn 5 2/5 into an improper fraction:

5 * 5 = 25 + 2 = 27/5

So they worked for 27/5 days.

We want to divide the days worked by the distance to get the unit rate of distance per day:

$\frac{12}{\frac{27}{5} } = \frac{12}{1} * \frac{5}{27}=\frac{60}{27}=\frac{20}{9}$

So our answer is 2 $\frac{2}{9}$

Hope this helps, have a great day! :D
