The price of a CD player was reduced from $80 to $52. What was the percent decrease in the price of the CD player?
Answer:
35%
Step-by-step explanation:
The cd players price decresed by 35%
The percentage decrease is given by the equation P = 35 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the percentage decrease be P
Let the original cost of the CD player be A = $ 80
Let the reduced price of the CD player be B = $ 52
Now , the equation will be
Percentage Decrease = [ ( | Measured Value - True Value | ) / True Value ]x 100
Substituting the values in the equation , we get
Percentage decrease P = [ ( 80 - 52 ) / 80 ] x 100
On simplifying the equation , we get
Percentage decrease P = ( 28/80 ) x 100
Percentage decrease P = 0.35 x 100
Percentage decrease P = 35 %
Therefore , the value of P is 35 %
Hence , the percentage decrease is 35 %

Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 15 hours to drain the pool by itself, how pump to drain the pool on its own?
Answer:
10
Step-by-step explanation:
Rate of drainage for pump A and B = [1 pool drained]/[6 hours]
Rate of drainage for pump A (older pump) = [1 pool drained]/[15 hours]
Rate for pump B (newer pump) = [1 pool drained]/[t hours]
Thus, adding the rate of drainage of A and B,
1/t + 1/15 = 1/6
t=10

The fox population in a certain region has a relative growth rate of 5 percent per year. It is estimated that
the population in the year 2000 was 29100.
a) Find a function that models the population t years after 2000 (t = 0 for 2000).
P(t)
b) Use the function from part (a) to estimate the fox population in the year 2008. Round to the
nearest fox.
foxes
Answer:
A: P(t)=29100e^(.05t)
B: ≈43412
Step-by-step explanation:
A: The formula A=Pe^(rt) can be used. Initial value of 29100, e is the exponential constant, the rate is 5% which can be seen as 5/100, and t=time
B: Use the equation you created and substitute 8 for t since the years of difference between 2008-2000 is 8 years
29100e^(.05(8)) ≈ 43412.0987014
Rounded to the nearest fox is ≈43412

512 cm³Step-by-step explanation:
Let us understand the letters in the formula first. The rest is really quite simple.
V = volume
A = area
Let's substitute the known area in for A
V = 64^3/2
Solve for V
64^3/2 = 512
V = 512
Hence, the volume of the cube is 512 cm³
