the percent increase in the price of a gallon of milk from 1985 to 2005 is 59%
Define percent increase
Percent increase can be described as the rise in the value of an item, in this case the value is milk.
Write out the parameters
In 1985 the price of a gallon of milk is $2.20
In 2005 the price is $3.50
Formula for percent increase
new price-old price/new price × 100
Calculate the percent increase
new price= $3.50
old price= $2.20
= 3.50-2.20/2.20
= 1.3/2.20
= 0.59 × 100
= 59%
Hence the percent increase from 1985 t0 2005 is 59%

Answer: 2,125,764
Step-by-step explanation:
You can use the equation y=ar^n-1 to find the 13th term where a is the starting term, r is the common ratio, and n is the nth term
The next number is 12/4=3 times greater than the first. So if this sequence is a geometric one, then the next term must be 12*3=36. This is true, and the next term must be 36*3=108, which is also true. Therefore this sequence is a geometric one and its common ratio is 3. Therefore the equation is:
y=4*3^(n-1)
Substitute 13 for n:
y=4*3^(13-1)
y=4*3^12
y=2125764
Therefore, the 13th term of this geometric sequence is 2,125,764
Answer:
Approximately the number of men is 203 and number of women is 47.
Step-by-step explanation:
It is given that the United States Air Force has 19 women for every 81 men enlisted.
It means the ratio between men and women is 81:19.
Sum of ratio is
Therefore for each 100 people, there are 81 men and 19 women.
Total number of peoples is 250.
In 250 members the number of men is
The numbers of persons cannot be a fraction values or a decimal value, therefore the number of men is 203.
In 250 members the number of women is
Therefore approximately the number of men is 203 and number of women is 47.
