Stella went shopping for a new camera because of a sale. The store was offering a 20% discount. If the price on the tag was $23, what would be the price after the discount but before tax, to the nearest dollar and cent?
The price after the discount but before tax, to the nearest dollar and cent, is $18.4.
Given Information:
Price on the tag = $23
Amount of Discount =20%
A % or Percentage is a figure or ratio that is stated as a fraction of 100 (from the Latin per centum, "by a hundred"). A % lacks dimensions and has no associated unit of measurement.
Percentage Formula =[tex]\frac{value}{Total value} *100[/tex]
Calculating the discount,
There is a 20 % discount on the camera
So, the amount of discount by using the percentage formula = [tex]\frac{20*23}{100} = 4.6[/tex]
Hence, the amount of discount is $4.6
Subtracting the discount to calculate the price after the discount =
Initial Price - Discount amount = $23-$4.6 = $18.4
Thus, the price after the discount is $18.4

Step-by-step explanation:
a wire of length 38 m is divided into two pieces and each piece is bent into a square. how should this be done in order to minimize the sum of the areas of the two squares? (give your answer in the form of a comma separated list of the lengths of the two pieces.)
The lengths of the two pieces of a wire will be 19,19.
Define square.A square is a closed, two-dimensional object with four equal sides and four vertices. On either side, it has parallel sides.
The square of a square's side determines its area.
Given data -
Length of a wire = 38 m
As the wire is divided into two pieces,
Let the length of two pieces of wire be x and y m respectively.
As per given data, x + y = 38
Therefore, y = 38 - x
As each piece is bent into a square, area of squares will be
[tex](x/4)^{2}[/tex] and [tex](y/4)^{2}[/tex]
Therefore, the sum of areas of two squares will be A = [tex](x/4)^{2}[/tex] + [tex](y/4)^{2}[/tex]
A = [tex]x^{2}[/tex]/16 + [tex]y^{2}[/tex]/16
A = [tex]x^{2}[/tex]/16 + [tex](38-x)^{2}[/tex]/16
By differentiating, we will get
A' = [tex]\frac{2x}{16}[/tex] - [tex]\frac{2(38-x)}{16}[/tex]
In order to minimize the the sum of the areas of the two squares, we will take A' = 0
0 = x - (38 - x)
2x = 38
x = 19
Therefore y = 19
The length of two pieces of a wire should be 19 m each.

If in lixue's garden the green pepper plants grew 5 inches in 3/4 months then at this rate they can grow 0.555 feet in one month
The problem is solved as per the unitary method
In lixue's garden the green pepper plants grew 5 inches in 3/4 months.
In 3/4 months the green pepper grew by 5 inches.
3/4 months can be written as 0.75 months

Find the equation of the line that passes through (-1,2) and is perpendicular to 2y=x−3.
Leave your answer in the form y=mx+c
Answer:
y = -2x.
Step-by-step explanation:
2y = x - 3
y = 1/2x - 3/2
- so, the slope of this line is 1/2
and the slope of a line perpendicular to it is - 1/ 1/2
= -2.
Using the point slope form of a line the equation of the required line is
y - y1 = m(x - x1)
m = -2, x1 = -1 and y1 = 2.
So,
y - 2 = -2(x - (-1))
y - 2 = -2x - 2
y = -2x - 2 + 2
y = -2x.

What is a function and domain and range of a function?
A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
The set of values for which the function is defined is the domain of the function and the values obtained on substituting the values of domain in the function is the range of the function.
y = [tex]\frac{x -5}{2x + 4}\\[/tex]
For domain of y
y is not defined if 2x +4 = 0
y is not defined if [tex]x = -\frac{1}{2}[/tex]
Domain of y = [tex]\mathbb{R} -[/tex] {[tex]-\frac{1}{2}[/tex]}
For range of y
let [tex]\frac{x -5}{2x + 4}\\[/tex] = z
[tex]x - 5 = z(2x +4)\\x - 5 = 2zx + 4z\\x - 2zx = 4z + 5\\x(1 - 2z) = 4z + 5\\x = \frac{4z + 5}{1 - 2z}[/tex]

use the commutative law of multiplication to rewrite 146 x 48
Step-by-step explanation:
146 × 48 = 48 × 146
due to the commutative law of multiplication the sequence of the operands of a multiplication does not matter.
a × b = b × a
this bases on the fact that a multiplication is nothing else than a special kind of addition
a × b = add a b times; or add b a times.
and as already the addition follows the commutative law
a + b = b + a

The fractional equivalent of the repeating decimal n = 0.1515... is 5/33, with two repeating digits.
What is a fractional equivalent?A fractional equivalent is a fraction that shares the same equivalent value with a decimal.
For instance, the equivalent fraction of 0.1515 is 303/2000. But for a repeating decimal like 0.1515..., the equivalent fraction is 5/33.
When numbers or values are said to be equivalent, it means that they are equal.
By their nature, repeating decimals continue endlessly.
Let x = 0.1515... equation 1
100x = 15.1515... equation 2
Subtract equation 1 from equation 2:
100x = 15.1515...
x = 0.1515...
99x = 15
x = 15/99
x = 5/33
Thus, n = 0.1515... as a repeating decimal or 5/33 as a fraction.

Hint: Multiply the probability of the 1st Event by the
probability of the 2nd Event to

Enter
If the first marble is not reinserted into the bag before the second draw, there is 1/15 probability of drawing two pink marbles.
What are dependent events?When the result of one event affects the result of another, two events are said to be dependent. The likelihood of two connected events is the sum of the probabilities of the occurrences X and Y that happen after X.
It is given that there are two yellow, three pink and 5 blue marbles.
So, in the first draw, the probability of drawing pink marble is the ratio of the number of pink marbles to the total number of marbles in the bag.
[tex]p_1=\frac{3}{10}[/tex]
Now, in the second draw, the probability of drawing pink marbles will be affected as it is not kept back. So, in the second draw, the probability of drawing pink marble is the ratio of the number of remaining pink marbles to the remaining number of marbles in the bag.
[tex]p_2=\frac{2}{9}[/tex]
Given that both occurrences occur concurrently, multiply the likelihood of the first event by the probability of the second event.
[tex]p=p_1\times p_2\\\\=\frac{3}{10}\times\frac{2}{9}\\\\ =\frac{1}{15}[/tex]
So, If the first marble is not reinserted into the bag before the second draw, there is 1/15 probability of drawing two pink marbles.
