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

If the first marble is not reinserted into the bag before the second draw, there is 1/15 probability of drawing two pink marbles.

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.

Given:

A U.S. Geological Survey map has a scale of 1:24200

There are two buildings that are 3.38 miles apart.

We will find how they are inches apart on the map

First, convert from miles to inches

1 mile = 63 360 inches

So, 3.38 miles = 3.38 * 63 360 inches = 214156.8 inches

The map has a scale of 1:24200

So, using the ratio and the proportions, we will find the length on the map as follows:

Rounding to the nearest hundredth

So, the answer will be: 8.85 inches

Answer:

The right answer choices are B, C, and F

The fractional equivalent of the repeating decimal n = 0.1515... is 5/33, with two repeating digits.

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.

The most appropriate choice for function and domain and range of a function will be given by -

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]

Given that g(x)=2x + 1,

therefore, the value of g(a+h) and g(a) can be written as,g(x)=2x + 1g(a+h)=2(a+h) + 1     
   = 2a + 2h + 1

g(x) = 2x + 1g(a) = 2(a) + 1

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

in 1 month the green pepper plant will grow by (5/0.75) 1

The green pepper plant will grow by 6.66 inches

1 foot is equals to 12 inches

1 inch = 1/12 foot

6.666 inches = (1/12) 6.666

= 0.0833 x 6.666

= 0.555

The lengths of the two pieces of a wire will be 19,19.

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.

The value of the smaller number is 5

From the question, we are to determine the value of the smaller number

Let one of the numbers be x and the other number be y

From the given information,

The difference of two numbers is 1

That is,

x - y = 1

and

Their sum is 11

That is,  

x + y = 11

Now, we will solve the equations simultaneously

From the first equation

x - y = 1

x = 1 + y     ------------- (3)

Substitute into the second equation

x + y = 11

1 + y + y = 11

1 + 2y = 11

2y = 11 - 1

2y = 10

y = 10/2

y = 5

Substitute the value of y into equation (3)

x = 1 + y

x = 1 + 5

The length of the arc whose central angle is 50° is 10.91.

Here, we are given that a circle has a circumference of 25π.

The length of the arc of a circle is given by the following formula-

(∅/360)*2πr

where ∅ is the measure of the angle that the arc subtends at the center and r is the radius of the circle.

Here, we are already given the circumference, thus, 2πr = 25π.

And, the central angle is given to be 50. Thus, ∅ = 50

Now, substituting the values in the above formula we can calculate the length of the arc as follows-

(50/360)*25π

= 5/36 × 25π

= 125/36 × 22/7

= 2,750/ 252

= 10.91

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.
