The guy below is correct!

Answer:  The required percentage is 33.02%.

Step-by-step explanation:  Given that a bookstore owner is having a sale. The book Bart wants was originally priced at $14.99 the book is now $10.04.

We are to find the percentage by which the price was reduced.

The price by which the price of the book reduced is given by

R.P. = $(14.99 - 10.04) = $4.95.

Therefore, the percentage by which the price of the book reduced is given by

[tex]P=\dfrac{4.95}{14.99}\times 100\%\\\\=33.02\%[/tex]

Thus, the required percentage is 33.02%.

The price of the book was reduced by approximately 33.02% from its original price of $14.99 to the sale price of $10.04.

The student asked by what percentage the price of a book was reduced from its original price of $14.99 to its sale price of $10.04.

To calculate the percentage decrease, we subtract the sale price from the original price and then divide by the original price. We then multiply the result by 100 to get the percentage.

Here's the step-by-step calculation:

Therefore, the price of the book was reduced by approximately 33.02%.

Answer:

The correct answer is option A 43°

Step-by-step explanation:

From the figure we can see a triangle and two exterior angles are given.

To find the value of p

Here we consider two angles be <1 and < 2, where <1 is the linear pair of angle measures 90° and <2 be the linear pair of angle measures 133°

m<1 = 180 - 90 = 90° and

<2 = 180 - 133 = 47

By using angle sum property

m<1 + m<2 + p = 180

p = 180 - (m<1 + m<2)

 = 180 - (47 + 90)

 = 180 - 137

 = 43°

Therefore the correct answer is option A 43°

Step-by-step explanation:

16 cups = 4 quarts

Please mark brainliest and have a great day!

Answer:

4 quarts

Step-by-step explanation:

We are given that a container of fruit punch serves 16 cups and we are to find the number of quarts that are in a container.

For this, we will use the ratio method.

We know that, 1 cup = 0.25 quarts, so:

[tex] \frac { 1 cup } { 1 6 cups } = \frac { 0 . 2 5 quarts } { x } [/tex]

[tex] x = 1 6 \times 0 . 2 5 [/tex]

[tex]x=4 quarts[/tex]

Therefore, there are 4 quarts of fruit punch in the container.

Answer:

SD = 17.1 miles

Step-by-step explanation:

In order to find the SD we have to calculate mean first

So,

[tex]Mean = \frac{sum}{no.\ of\ items} \\=\frac{25+40+35+25+40+60+75}{7}\\ =\frac{300}{7}\\ =42.86[/tex]

Now mean will be subtracted from each value and the answers will be squared

So,

X            X-mean          (X-mean)^2

25           -17.86            318.9796

40            -2.86             8.1796

35             -7.86            61.7796

25            -17.86            318.9796

40             -2.86             8.1796

60             17.14             293.7796

75              32.14           1032.9796

So,

Sum of squares = 2042.8572

As SD is the square root of variance

so,

Variance = Sum of squares / number of data values

=2042.8572/7

=291.84

Hence,

[tex]SD = \sqrt{Variance} =\sqrt{291.84} \\=17.083\\to\ the\ nearest\ tenth\\SD=17.1\ miles[/tex]   ..

Answer:

c: g(x) is shifted 3 units to the right and reflected over the x-axis

Answer: Option D

g(x) is shifted 3 units to the left and reflected over the x-axis.

Step-by-step explanation:

If we have a function f(x) and make a transformation of the form:

[tex]g (x) = f (x + h)[/tex]

Then it is true that:

If [tex]h> 0[/tex] the graph of g(x) is equal to the graph of f(x) displaced h units to the left

If [tex]h<0[/tex] the graph of g(x) is equal to the graph of f(x) displaced h units to the right

Also if we have a function f(x) and perform a transformation of the form:

[tex]g (x) = -f (x)[/tex]

Then it is true that:

The graph of g(x) is equal to the graph of f(x) reflected on the x axis.

In this case [tex]f (x) = x ^ 4[/tex] and [tex]g (x) = -(x + 3) ^ 4[/tex]

So

[tex]g(x) = -f(x+3)[/tex]

Then [tex]h = 3> 0[/tex]. Therefore the graph of g(x) is equal to the graph of f(x) displaced 3 units to the left and reflected on the x axis

The answer is the option D

Answer:  d) No solution.

Step-by-step explanation:

Given the equation:

 [tex]\frac{3}{2}=\frac{3x}{2x}-\frac{6}{5x}[/tex]

The denominator of the fractions cannot be zero, then, the Domain is:

[tex]x\neq 0[/tex]

Simplify:

 [tex]\frac{3}{2}=\frac{3}{2}-\frac{6}{5x}[/tex]

Subtract [tex]\frac{3}{2}[/tex] from both sides of the equation. Then you get:

[tex]\frac{3}{2}-(\frac{3}{2})=\frac{3}{2}-\frac{6}{5x}-(\frac{3}{2})\\\\0=-\frac{6}{5x}[/tex]

Multiply both sides of the equation by [tex]5x[/tex] ([tex]5x \neq 0[/tex]), then:

[tex](5x)(0)=(-\frac{6}{5x})(5x)[/tex]

Since the multiplication of [tex]5x[/tex] by zero is zero, you get:

 [tex]0=-6[/tex]  (This is FALSE)

Therefore, since there is no value for the variable that makes the equation true, the equation has NO SOLUTION.

Answer:

CORRECT ANSWER IS 1/5

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

From any point (x, y) on the parabola the focus and directrix are equidistant

Using the distance formula

[tex]\sqrt{(x+5)^2+(y-5)^2}[/tex] = | y + 1 |

Squaring both sides

(x + 5)² + (y - 5)² = (y + 1)^2 , that is

(y + 1)² = (x + 5)² + (y - 5)² ← subtract (y - 5)² from both sides

(y + 1)² - (y - 5)² = (x + 5)² ← expand left side and simplify

y² + 2y + 1 - y² + 10y - 25 = (x + 5)²

12y - 24 = (x + 5)² ← factor left side

12(y - 2) = (x + 5)² ← divide both sides by 12

y - 2 = [tex]\frac{1}{12}[/tex] (x + 5)² ← add 2 to both sides

y = [tex]\frac{1}{12}[/tex] (x + 5)² + 2

or

f(x) = [tex]\frac{1}{12}[/tex] (x + 5)² + 2 → D

You're right. It is D All real numbers

There are no restrictions to the value of x

The domain of the given function is "All real numbers". So, option D is correct.

The given function is f(x) = 2×[tex](\frac{1}{10})^x[/tex]

Since this function has the variable x in the exponent, this is an exponential function.

So, its inputs are of all real numbers. And the domain is {x:x ∈ R}.

Thus, option D is true.

Answer:

C) 33%

Step-by-step explanation:

To solve for the percentage of success, we first need to find out how many numbers we are working with. In this case, there are 9 numbers (0,1,2,3,4,5,6,7,8).

Since there are 3 "successful" numbers, (0,1,2), we can write the probability as a fraction

3/9 (represents number of successes over number of possible outcomes)

This simplifies to be 33%

Answer:

C

Step-by-step explanation:

Since you include zero as a number, then it would be 9 numbers in all. 3 if the nine numbers are success, so it would be 3/9. 3/9 as a percent would be around 33 percent.

Step-by-step explanation:

opposite = 14

Tan(B) = opposite / adjacent

Tan(B) = 14 / 8

Tan(B) = 1.75

B = tan-1(1.75)

B = 60.3

The function for the reflection across the y-axis can be written as: f(x,y)=(−x,y)

To reflect a point across the y-axis, we multiply its x-coordinate by -1. This means that if a point has coordinates (x,y), its reflection across the y-axis will have coordinates (−x,y).

We can use this to define a function for the reflection across the y-axis. Let f(x,y) be the function that reflects a point across the y-axis. Then, for any point (x,y), we have:

f(x,y)=(−x,y)

In other words, f(x,y) takes a point (x,y) and returns its reflection across the y-axis.

We can also write this function in terms of components. Let x and y be the coordinates of a point. Then, the reflection of this point across the y-axis has coordinates (−x,y). Therefore, the function for the reflection across the y-axis can be written as:

f(x,y)=(−x,y)

This function takes the coordinates of a point as input and returns the coordinates of its reflection across the y-axis as output.

Answer:

C) 360π

Step-by-step explanation:

Note the formula for the volume of Cylinder:

V(olume) = πr²h

π = 3.14

r = radius

h = height of the cylinder

V = (3.14)(6²)(10)

Simplify. First, solve the power, then multiply

V = (3.14)(36)(10)

V = 3.14 * 360

V = 1130.97

However your answer choices all shows π, so just back track a bit.

First option : 0.1904

Step-by-step explanation:

Given

[tex]P(A) = 0.56\\P(B)= 0.34[/tex]

First of all, we will define independent events.

Two events are said to be independent if the occurrence of one event doesn't affect the probability of occurrence of second event.

If the events are independent then their individual probabilities are multiplied for the probability of both events.

That is:

P(A∩B) = P(A) * P(B)

= 0.56 * 0.34

=0.1904

So, the probability of A and B is 0.1904.

Hence, first option is the correct answer ..

Answer:

The answer is 0.1904

Step-by-step explanation:

The probability of event A is 0.56, and the probability of event B is 0.34. If A and B are independent events, then P(A and B) = 0.1904
