Farmer Finnegan needs to build a fence to keep his horses on his property. He only has a little over 1.5 miles of fence materials, but there’s also a mile-long straight river running through his property. What shape should he use for the fenced in area to give his horses the most space possible?
Our dear friend Finnegan should build a half-circle fence with the river as the diameter, giving the horses about 0.4 square miles to frolic and play in.
Area of semi-circle = πr2 / 2 = π × .5 miles2 / 2 = 0.3927
Early one morning Hal, the owner of a hardware store, sells a mailbox for $25 to Courtney that cost him $20 wholesale. Courtney pays with a $100 bill and Hal discovers he doesn’t have enough change. He runs to the jewelry shop next door, where Jack, the owner, gives him change in exchange for the $100. Later that afternoon, Jack discovers the $100 bill is a counterfeit and Hal pays him $100 to make it right.
The total loss was $95. -$20 = The wholesale cost of the mailbox $100 = The money from Jack -$75 = The change paid to Courtney -$100 = To pay Jack back -$20 + $100 – $75 – $100 = -$95
It’s easy to think Hal lost $195 but that fails to account for the $100 used to make the change, which came from Jack, not Hal. Jack paid $100 in exchange for a worthless piece of paper, so the $100 was initially Jack’s loss. Hal had made a $5 profit until Jack’s discovery. If you guessed $100, that’s arguably correct, but not making $5 in profit isn’t a loss in the strictest sense of the word.
I have palms but not on hands, I offer foods from distant lands, When at my peak you’ll see me smoke, I’m famous for my friendly folk, My flowers grow and yet they lay, There’s fire where a man will play, I’m sure you know we’re family, You’re welcome to come stay with me.
At a quirky fruit stand, an orange costs 18 cents, a pineapple costs 27 cents and a grape costs 15 cents. Using the same logic, how much does a mango cost?
9pm (or 21:00). There are 12 hours between 1pm and 1am, so 6 hours after 1am is halfway. 6 hours + 1pm equals 7pm. In order for 7pm to be 2 hours behind the current time, it must be 9pm.
Smoke. It rises then slowly dissipates in the air. Smoke signals send messages and incense is used in religious ceremonies. Anyone who’s sat at a bonfire knows smoke in your eyes can make you cry when the wind changes direction. Smoked meats are a tasty treat, but if you see heavy smoke (i.e. from a fire) then run. Or stop drop and roll if the fire already caught you.
