An arc has a length of 123.53 millimeters and a radius of 28 millimeters.

What is the measure of the angle of the sector in degrees? Round to the nearest degree.

Angle of sector = Degrees

Step-by-step explanation:

The formula for the length of an arc is

We have L = 123.53 and twice the radius as 56.  Filling in:

Begin by multiplying both sides by 360 to get

 and divide both sides by 56π to get

θ = 253°

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
