Select the correct answer from each drop-down menu. A teacher is making a history test composed of the same number of multiple-choice questions as short-answer questions. She estimates it will take students an average
of 2 minutes to complete each multiple-choice question and an average of 3.5 minutes to complete each short-answer question
Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.

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 )
