Answer:

270 degrees

Step-by-step explanation:

Area  \: of  \: the  \: sector  \\  \\  =  \frac{ \theta}{360 \degree} \times  \pi {r}^{2} \\  \\ 339.3 =  \frac{ \theta}{360 \degree} \times  3.14 {(12)}^{2}  \\  \\ 339.3 =  \frac{ \theta}{360 \degree} \times  3.14  \times 144 \\  \\  \theta =  \frac{339.3 \times 360 \degree}{3.14 \times 144} \\  \\  \theta =  \frac{122,148\degree}{452.16}  \\  \\  \theta= 270.143312 \degree \\  \\ \theta \approx \:  270\degree

Sally gets paid $15.00 dollars per hour for a 40-hour work week and y dollars for each hour she works over 40 hours. What is the
Anna35 [415]

The equation x = 600 + 8y represents the earnings of Sally if she works 48 hours.

<u>Step-by-step explanation:</u>

  • Sally gets paid $15.00 dollars per hour for a 40-hour weekly work.
  • She gets y dollars for each extra hour she works over 40 hours.

<u>The equation can be framed as :</u>

Let,

  • x be the total pay she could get for 48 hours.
  • The amount she earned for 40 hours = 40 × $15 ⇒ $600
  • The amount she earned for extra hours = 8 × y ⇒ 8y

The equation is given as,

Total earnings = amount earned for 40 hours + amount for extra 8 hours.

⇒ x = 600 + 8y

Therefore, the equation x = 600 + 8y represents the earnings of Sally if she works 48 hours.

Howhowhow?how??? how would you calculate
Liula [17]

Ok sooooooooooo

Lets say your two fractions are

13/26 and 20/40

you can divide the bottom number by the top one and if you get the same answer for both then they are equivalent. For these you get 2 for both, which means they are equivalent.

another example would be if your fractions are

2/5 and 4/10

You can say well 2*2 equals 4 And 5*2 equals ten so these are equivalent fractions.
