Concert the angle 0=14r/9 radians to degrees
Mila [183]

Answer:

  θ = 280°

Step-by-step explanation:

We assume your intended equation is ...

  θ = 14π/9 . . . . radians

π radians is 180°, so we can simply put 180° where π is in your equation.

  θ = 14(180°)/9

  θ = 280°

Jeanette wants to raise $3,200 in a marathon fundraiser. Her sponsers will donate
rosijanka [135]

Total amount she wants to raise = $3200

Amount she'll get for each kilometer = $35

So, number of kilometers she need to run

= Total amount she wants to raise/Amount she'll get for each kilometer

= $3200/$35

= 91.42....

Since her sponser is will donate only for whole kilometers she'll have to run 92 km.
