The Hudson Record Store is having a going-out-of-business sale.CDs normally sell for $18.00.During the first week of the sale, all CDs will sell for $15.00.Written as a fraction, what is the rate of discount?What is the rate expressed as a percent?Round your answer to the nearest hundredth of a percent.During the second week of the sale, the same CDs will be on sale for 25% off the original price.What is the price of a CD during the second week of the sale?
Answers
Original Price = $18
Discounted Price = $15
Discount is $3 as 18-15 is 3.
As a fraction, the discount rate is $3/$18 also equal to $1/$6
What is the rate expressed as a percent? Round your answer to the nearest hundredth of a percent.1/6 is approximately 0.167
0.167 = 16.67%
As a percent, the discount rate is 16.67%
During the second week of the sale, the same CDs will be on sale for 25% off the original price. What is the price of a CD during the second week of the sale?Using the formula, Amount of Discount = Discount Rate · Original Price we can find the amount of discount for the 2nd week.
Let x be the amount of discount.
x = 25% · $18
x = $4.50
The amount of discount is $4.50
Calculate the cost of the CDs during the second week: $18 - $4.50 = $13.50
The price of a CD during the second week of the sale is $13.50

The factored form of a quadratic function is f(x)=(x-p)(x-q).The standard form of a quadratic function is fX)=ax^2+bx+c. The factored
form for a quadratic function tells us the x-intercepts of the quadratic function, while the standard form for a quadratic function tells us they
intercept of the quadratic function.
If p=2 and q=-3, use what you have learned about multiplying polynomials to
1) write the factored form of the quadratic function f(x)
2) write the standard form for the quadratic function f(x)
Answers
Answer:
(1) f(x)=(x-2)(x-3)
(2) f(x)=x²-5x+6
Step-by-step explanation:
(1) f(x)=(x-p)(x-q)
f(x)=(x-2)(x-3)
(2) f(x)=x²-3x-2x+6

The expression for the number of chocolates remaining will be c = 24 - 4t.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that, Zoe was given a box of assorted chocolates for her birthday. Each night, she to some chocolates. Zoe ate 4 chocolates each night and after 3 nights, there were 12 chocolates remaining in the box.
Let the number of days be represented by t, and the number of chocolates will be C.
The total number of chocolates will be calculated as,
Total = 3 x 4 + remaining chocolates = 12
Total = 3 x 4 + 12
Total = 12
The expression will be written as,
C = 24 - 4t
Therefore, the expression for the number of chocolates remaining will be c = 24 - 4t.

Use the Pythagorean theorem to find each missing length to the nearest tenth
Answers
explanation: a^2 + b^2 = c^2
plug in 3 for a and 10 for b

simplify to get

take the square root of both sides
c = sqrt109 or 10.44030651
Answer:
c (the hypotenuse) = 10.4 units
Step-by-step explanation:
Start off by rearranging the original pythangorean theorem (a^2+b^2=c^2) by taking the square root of both sides so it is in the form of a distance formula solving for c(the hypotenuse).
c^2 will become |c| as length cannot be negative so (labeling an absolute value is negligible)
a^2+b^2 = c^2
c^2 = a^2+b^2
√(c^2) = √(a^2+b^2)
c = √(a^2+b^2)
Then substitute the given lengths, in this scenario, sides a and b.
After you substitute, just simplify.
c = √(3^2+10^2) = √(9+100) = √109 ≈ 10.4 units (nearest tenth)

Answer:
10%
Step-by-step explanation:
We are told that To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number.
This means the total number of single digits that could possibly be a winning one is 10.
Since we are told that only 1 can be picked, thus;
Probability of winning is; 1/10 = 0.1 or 10%
