Olga buys tickets to a concert. She pays $27.75 for each ticket PLUS a handling fee of $5.50 for the order. The total cost is $144.25. (27.75n + 5.50 + = 144.25)

1) what does n represent?

2) what does 27.75n represent?

3) how much did Olga pay for the tickets without the handling fee? Explain how you know.

4) how can you solve the simplified equation that you wrote in problem 3? Solve the equation.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
