Estimate a 50% tip on a do the dinner bell of $47.84 by first round in the bill amount to the nearest $10
Andrej [43]

Answer:

Tip= $25

Step-by-step explanation:

<u>First, we need to round the bill to the nearest tenth.</u>

Bill= 47.84 = 50

<u>Now, we can calculate the tip using the following formula:</u>

Bill proportion= 50% = 0.5

Tip= Bill*tip proportion

Tip= 50*0.5

Tip= $25

On a $50 bill, the tip is $25. The total amount to pay is $75.

???? please help lol
kow [346]

Answer:

  1. 150π ft²
  2. 10π ft.

Step-by-step explanation:

Area of the sector :

Area (sector) = \pi r^{2} \times \frac{\theta}{360^{o}}

Finding the area given r = 30 ft. and θ = 60° :

⇒ Area = π × (30)² × 60/360

⇒ Area = π × 900/6

⇒ Area = 150π ft²

===========================================================

Length of the arc :

Length (arc) =2 \pi r} \times \frac{\theta}{360^{o}}

Finding the arc length given r = 30 ft. and θ = 60° :

⇒ Arc Length = 2 × π × 30 × 60/360

⇒ Arc Length = 60/6 × π

⇒ Arc Length = 10π ft.
