Valentina rented skis for $25, then took lessons that cost $9 per hour. The total cost to rent skies and take lessons was $46.25. Write an equation and draw a tape diagram that can be used to determine how many hours of ski lessons Valentina took.

than do 23.50 times 18 and then divide your answer by 100 than you will get x.

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 )
