Ed is on a road trip. he has already traveled 208 miles and is driving at a rate of 70 miles per hour. which equation could be used to find how many hours, x, ed has left in his road trip if he is traveling 695 total miles?
a.
70x + 208 = 695

b.
208x + 70 = 695

c.
208x + 695 = 70

d.
70x + 695 = 208

Ibelieve the answer would be 7, 13, 23

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 )
