Johan is comparing energy consumption for two different brands of refrigerators. The energy consumed "e", in watts, is proportional to the time "t", in hours, that the refrigerator is operating. The equation e=160t models the relationship for brand R. Another refrigerator, brand S, consumes energy at a constant rate of 435 watts in 3 hours. Which brand consumes less energy? Explain.

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 )
