Answer:
The one on the top left
Step-by-step explanation:
Slope of one third and y intercept -4
Since the amount if Caffeine decreases by 12% an hour, that is the same as a multiplier of 0.88 per hour.
r = ln 0.88 = -0.117833371
10 = 120 e^-0.117833371t
10/120 = e^-0.117833371t
0.8333 = 10/120
ln0.8333 = -2.48490665 so
e^-2.48490665 = e^-0.117833371t and so
-2.48490665 = -0.117833371t
-2.48490665/-0.117833371 = t
21.08830995 hrs = t
thus 21 hrs is your best answer.
250 pounds of meat are needed for 1,000 patties. We will multiply 0.25 x 1,000 which will equal 250lbs.
The total surface area of this square based pyramid is 125 squared inches :)
Divide the price by the quantity to see what's a better deal.
4.25 / 5 = 0.85
So, for each apple it costs 85 cents.
6.56 / 8 = 0.82
So, for each apple it costs 82 cents.
So, the $6.56 for 8 pounds of apples is the better deal.
