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 %

6. Write a formula to represent the nth term of the sequence: 3, 6, 12, 24, 48, 96,...
Given :
The sequence is given as : 3, 6, 12, 24, 48, 96,...
To Find :
A formula to represent the nth term of the given sequence.
Solution :
Breaking down each term we get :
3 = 3 × 2⁰ 1 - term
6 = 3 × 2¹ 2 - term
12 = 3 × 2² 3 - term
24 = 3 × 2³ 4 - term
48 = 3 × 2⁴ 5 - term
From above observation we can say that n th term is given by 3 × 2ⁿ⁻¹ .
Therefore, the nth them of the sequence is given by ( 3 × 2ⁿ⁻¹ ) .

The local business will donate $5.00 for every 10 tickets sold. Let x represent tickets sold, and y represents dollars donated. Student A claims that the equation is y = 2x. Student B claims that the equation is y = 1
2
x. Explain who is correct.
Answer:
y=2x
Step-by-step explanation:
x=number of ticket sold y = dollars donated
for every 10tickets sold 5 dollars would be donated
10x = 5y divide both sides by 5
2x = y. same as. y = 2x.

Consider the first five terms of the following sequence.
2, 6, 18, 54, 162, ...
If the sequence defines a function, what is a reasonable domain and range of the function?
O A. Domain: all real numbers; Range: all real numbers
B. Domain: {1, 2, 3, 4, 5, ...}; Range: {2, 6, 18, 54, 162, ...}
C. Domain: {1, 2, 3, 4, 5, ...}; Range: all real numbers
O D. Domain: all real numbers; Range: {2, 6, 18, 54, 162, ...}
Answer:
B. Domain: {1, 2, 3, 4, 5, ...}; Range: {2, 6, 18, 54, 162, ...}
Step-by-step explanation:
2, 6, 18, 54, 162
This is a geometric sequence because it is increasing by multiplication. The common ration of the sequence is *3.
Our sequence values will serve as the y-values, or the range, and our x-values will be the term number.
Domain, or x-values: {1, 2, 3, 4, 5, ...}
Range, or y-values: {2, 6, 18, 54, 162, ...}
It is not A or D because we can't have negative term values. "All real numbers" implies all positive and negative integers.
The range also cannot be all real numbers for the same reason.

= 4x² + 6x + 9 - ( 2x (x - 5) + 3(x - 5 ))
= 4x² + 6x + 9 - ( 2x² - 10x + 3x - 15 )

Plz I really need help!! What is the measure of angle B in the triangle?
This triangle is not drawn to scale.
Enter your answer in the box.
mZB=
Answer:
70
Step-by-step explanation:
Hello There!
In order to find the measure of angle B we need to solve for x
Remember the sum of the angles in a triangle is 180
so we can solve for x using the equation
180=40+x+20+2x-30
step 1 combine like terms
40+20=60 60-30=30
2x+x=3x
now we have
180=3x+30
step 2 subtract 30 from each side
180-30=150
30-30 cancels out
step 3 divide each side by 3
150/3=50
3x/3=x
we're left with
x=50
Now we plug in 50 into x in 2x-30
2*50=100
100-30=70 so we can conclude that
angle B = 70

The volume of the cube (V)
[tex]v \: = {a}^{ \frac{3}{2} } \\ v \: = 64 ^{ \frac{3}{2} } \\ v = 8 ^{ \frac{3 \times 2}{2} } \\ v \: = {8}^{3} \\ v = 512cm ^{3} [/tex]
Hope it will help :)❤
Answer:
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

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
