One Half
How many times should he go around to mow one half of the lawn?
Randy and his sister agreed that they would each mow one-half of the lawn. The lawnis 25′ x 45′ rectangle. The lawn mower cuts a path two feet wide. Randy starts at one corner and mows a path completely around the outside.
Lawn is 25′ by 45′ = 1125′
First time around he mows 1125′ – (21*41) = 1125-861 = 264′
Second time he mows 861′ – (17*37) = 232′
Third time he mows 629 – (13*33) = 200′
Half of 1125 is 562.5.
He needs to mow 264 + 232 + 200x = 562.5
496 + 200x = 562.5
66.5 = 200x
x = .3325
He needs to mow all the way around twice and about 1/3 the way around the third time.

Half A Life $18.59 ‘Half my life ago I killed a girl.’ So begins acclaimed novelist Darin Strauss’ Half a Life the true story of how one outing in his father’s Oldsmobile resulted in the death of a classmate and the beginning of a different darker life for the author. The police assured him there was nothing he could have done to avoid hitting Celine’s swerving bike but for half his life Strauss has grappled with desperate feelings of remorse and self-blame. Here he lays bare his history – collision funeral the queasy drama of a high-stakes court case – and what starts as a personal tale of a tragic event opens into the story of how to live with a very hard fact: we can try our human best in the crucial moment and it might not be good enough. Half a Life is a nakedly honest ultimately hopeful examination of guilt responsibility and living with the past. |
