Write an equation that represents the following problem. there are two cell phone plans available from cell phones r us company. plan a charges $35 a month plus $0.05 for every text message. plan b charges $50 a month plus $0.01 for every text message. how many text messages do you need to send in order for plan a to cost the same as plan b? 35 + 5m = 50 + m 50 + 0.05m = 35 + 0.01m 35 + 0.05m = 50 + 0.01m 35 + m = 50 + 5m

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 )
