Adeal about some bicycles for $4000 he sold them for 6200 making $50 on each bicycle how many bicycles was there

Total profit = 6200-4000 = 2200
number of bikes at $50 profit per bike
= 2200/50 = 44

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000

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 )
