A certain car depreciates such that its value at the end of each year is p % less than its value at the end of the previous year
icang [17]

Answer:

b(b/a)^2

Step-by-step explanation:

Given that the value of the car depreciates such that its value at the end of each year is p % less than its value at the end of the previous year and that car was worth a dollars on December 31, 2010 and was worth b dollars on December 31, 2011, then

b = a - (p% × a) = a(1-p%)

b/a = 1 - p%

p% = 1 - b/a = (a-b)/a

Let the worth of the car on December 31, 2012 be c

then

c = b - (b × p%) = b(1-p%)

Let the worth of the car on December 31, 2013 be d

then

d = c - (c × p%)

d = c(1-p%)

d = b(1-p%)(1-p%)

d = b(1-p%)^2

d = b(1- (a-b)/a)^2

d = b((a-a+b)/a)^2

d = b(b/a)^2 = b^3/a^2

The car's worth on December 31, 2013 =  b(b/a)^2 = b^3/a^2

William fills 1/3 of a water bottle in 5/9 of a minute. How many can be filled in a minute
Snezhnost [94]

For this case we can propose a rule of three:

\frac {1} {3}bottle ------------> \frac {5} {9}minutes

x --------------------------------------> 1 minute

Where the variable "x" represents the number of bottles that can be filled in 1 minute.

x = \frac {1 * \frac {1} {3}} {\frac {5} {9}}\\x = \frac {\frac {1} {3}} {\frac {5} {9}}\\x = \frac {9 * 1} {3 * 5}\\x = \frac {9} {15}\\x = \frac {3} {5}

Thus, William can fill \frac {3} {5} of a water bottle in 1 minute.

Answer:

William can fill \frac {3} {5} of a water bottle in 1 minute.
