The factory produces sewing machine parts. during one week, they produced 345, 298, 452 and 388 parts per day.
what was the average number of parts produced each day?

To find the average, add up ur numbers, then divide by how many numbers there are.

(345 + 298 + 452 + 388) / 4 = 1483/4 = 370.75 per day <=

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 )
