Madeline sold 200 tickets for a charter flight to Dallas. Some paid $200 for their tickets and some paid $250. Madeline's revenue for the flight was $44,000. Below is Madeline's work in determining how many of each ticket was sold.
x = number of $200 tickets
y = number of $250 tickets
200x + 250y = 44,000 Complete each of the
x + y = 200

Task.
200(200 - y) + 250y = 44,000
40,000 -y + 250y = 44,000
40,000 + 249y = 44,000
249y = 4,000
y = 16.1

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 )
