When the average price of an item increases from p1 to p2 over a period of n years, the annual rate of inflation r (in decimal f
Natali [406]

Answer:

the annual rate of inflation r is 0.023

Step-by-step explanation:

Given by the expression:

r=(\frac{p_2}{p_1})^{1/n}-1

The average price of a gallon of milk increased from $0.36 in 1913 to $3.53 in 2013.

Let p_1 = 0.36

p_2 =  3.53

n = 2013 - 1913 = 100

replacing our values into the given equation; then the annual rate of inflation r is as follows:

r=(\frac{3.53}{0.36})^{1/100}-1

r = 0.023

Hence, the annual rate of inflation r is 0.023

Let’s assume that one drop is equal to 50 µl. a total of 2366 drops will fill how many tablespoons?
lina2011 [118]
First, we have to set the volume in 1 tablespoon. It actually depends on the country you're living. In USA, 1 tablespoon is approximately 14.8 ml. In microliters, that is equal to 14,800 μL. Thus,

Volume of the liquid = 50 μL/drop * 2366 drops = 118,300 μL
Therefore, that is equivalent to
Number of tablespoons = 118,300 μL/14,800 μL = 7.99924 or approximately 8 tablespoons
