maks197457 [2]

Let angle be alpha

\\ \rm\Rrightarrow Area=50.24

\\ \rm\Rrightarrow \dfrac{\alpha}{360}\pi r^2=50.24

\\ \rm\Rrightarrow \alpha 3.14r^2=18086.4

\\ \rm\Rrightarrow \alpha r^2=5760

\\ \rm\Rrightarrow r^2=\dfrac{5760}{\alpha}

\\ \rm\Rrightarrow r=\sqrt{\dfrac{5760}{\alpha}}

If you have angle measure in degree put in place of Alpha and get the value elaw this is our final answer

Dima020 [189]

Answer:

<h3>2/3 lost is 1/3 kept</h3>

<h3>2/3 of the 1/3 kept is 2/9 lost</h3>

  • 3/9 x - 2/9 x = 4

  • 1/9 x = 4

  • x = 36

<h3>First she lost 2/3 of 36, which is 24. She had 12 left. Then she lost 2/3 of 12 which is 8. She had 4 left.</h3>

Can anyone identify the two variables
valentina_108 [34]
The two variables are time (x) and distance (y)

And the answer is they will meet after 1 mile

The function of the aunt and uncle is y=25x+5

The function of yourself is y2=30x

Since you want to know when you’ll meet, you just resolve y=y2 or 25x+5=30x

Wich will be x=1 so 1 mile
