Anton has some money saved for school. To increase the amount he has saved, he got a job and added all the money earned to the amount already
saved.
Anton was paid a constant rate in dollars per hour at his job.
After working 10 hours, the amount he had saved was $450.
After working 20 hours, the amount he had saved was $600.
Anton did not save any other money or spend any of the money he
had saved.

.
Which equation represents y, the amount of money in dollars Anton would
have saved after working x hours?
y = 30x+150
y = 10x+150
y = 15x+100
O y = 15x+300

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 )
