Answer:

11.02

Step-by-step explanation:

Remember to multiply the markdown and origin price and then sub what you get from the original price to get an answer. Goodluck

Answer:

$11.02

Step-by-step explanation:

1. Take the original price and multiply it by 33%.

16.45 * 0.33 = 5.4285

2. Round 5.4285 to two decimal places

5.43

3. Take your discount and subtract it from the original price.

$16.45 - $5.43 = $11.02

Answer:

I think Linear but i am not sure

Step-by-step explanation:

A linear function is a function with standard form y = mx + b, where m is the slope and b is the y-intercept, and whose graph looks like a straight line. There are other functions whose graph is not a straight line. These functions are known as nonlinear functions and they come in many different forms.

Answer:

I think the 4th line plot would not be true

Step-by-step explanation:

We could calculate the range and median.

A line plot, also known as a dot plot, is a type of graph that displays the distribution of a set of data. It consists of a number line with dots or X's placed above each data value to represent how many times that value appears in the data set.

Using the stem-and-leaf plot in the diagram, below, write out each data points given, which are:

68, 70, 80, 86, 88, 88, 96, 96, 97, 97, 98, 98, 99, 100, 100, 100, 100, 100

The line plot for these data would have the following frequency for each data point:

68 - 1 dot

70 - 1 dot

80 - 1 dot

86 1 dot

88 - 2 dots

96 - 2 dots

97 - 2 dots

98 - 2 dots

99 - 1 dot

100 - 5 dots

The line plot is shown in the diagram below.

Range = 100 - 68 = 32

Median = 97

Therefore, We could calculate the range and median.

Answer:

There will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days

Step-by-step explanation:

The given parameters are;

The half life of the radioactive substance = 45 days

The mass of the substance initially present = 6.2 grams

The expression for evaluating the half life is given as follows;

[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]

Where;

N(t) = The amount of the substance left after a given time period = 1 gram

N₀ = The initial amount of the radioactive substance = 6.2 grams

[tex]t_{1/2}[/tex] = The half life of the radioactive substance = 45 days

Substituting the values gives;

[tex]1 = 6.2 \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]

[tex]\dfrac{1}{6.2} = \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]

[tex]ln\left (\dfrac{1}{6.2} \right ) = {\dfrac{t}{45} \times ln \left (\dfrac{1}{2} \right )[/tex]

[tex]t = 45 \times \dfrac{ln\left (\dfrac{1}{6.2} \right ) }{ln \left (\dfrac{1}{2} \right )} \approx 118.45 \ days[/tex]

The time that it takes for the mass of the radioactive substance to remain 1 g ≈ 118.45 days

Therefore, there will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days.

Answer:

$417.50 should be the correct answer you just multiply  the $7.25 to 30 and then add the $200.

Answer:

$417.50

Step-by-step explanation:

To calculate the total cost you will need to use this equation: 200 + 7.25n. n represents the number of people renting the course. 200 is the initial cost and then you add it with the cost of 30 people.

Answer: 500 adults tickets were sold

Step-by-step explanation: So you can do 563 subtract 63 to get the answer of 500

Answer:

x = 43 1/3 degrees

Step-by-step explanation:

sum of interior angles in a triangle = 180 degrees

30 + (3x - 9) + 29 = 180

30 + 29 + (3x - 9) = 180

59 + (3x - 9) = 180

(3x - 9) = 180 - 59

(3x - 9) = 121

3x = 121 + 9

3x = 130

x = 43 1/3

Answer:

17 years

Step-by-step explanation:

In order to calculate this, we need to create an equality equation. In this scenario, we have the fixed values which are the total population and the rate of growth, and we also have one variable which is the number of years. We can use these values to create the following equation.

2,425 + 27x = 1,813 + 63x

Now that we have the equation we can solve for x to calculate how many years it will take for them to be the same population.

2,425 + 27x = 1,813 + 63x   ... subtract 1,813 and 27x from both sides

612 = 36x   ... divide both sides by 36

17 = x

Finally, we can see that both populations will be the same after 17 years.

Answer:

x = -6

Step-by-step explanation:

you want to solve the aswer so you wanna solve for whats in the parenthesis so your new equation should look like this:

8x + 48 = 3

you want to subtract 48 from both sides  your new equation should look like this:

8x = -45

now you want to get x by itself and your new equation should be:

x = -6

Answer:

y = 19.99x + 30

Step-by-step explanation:

y = 19.99x + 30

The x represents the number of hours, and because it costs 19.99 per hour, the coefficient before the x will be 19.99. The y-intercept is the fee because it doesn't change with the x.

Answer:

20 cakes

Step-by-step explanation:

Given

28 cakes in 7 days

Required

Determine the number of cakes in 5 days

Represent the required with x. The question illustrates proportionality.

First, we need to represent the given and required as a ratio

[tex]28 : 7 = x : 5[/tex]

Convert ratios to fraction

[tex]\frac{28}{7} = \frac{x}{5}[/tex]

[tex]4 = \frac{x}{5}[/tex]

Solve for x

[tex]x = 4 * 5[/tex]

[tex]x = 20[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

Y=3

Answer:150%

Step-by-step explanation:because 50% increases

The number of houses sold this month are -

y = 3x/2.

In mathematics →

Given is that compared to last month, there was a 50% increase in the number of houses sold this month.

Assume that the number of houses sold of previous moth were [x]. Then, we can write -

y = {x} + 50% of {x}

y = {x} + (50/100) × {x}

y = {x} + {x/2}

y = 3x/2

Therefore, the number of houses sold this month are -

y = 3x/2.

The two of the possible solutions to the equation sin(5x - π) = (√2)/2 are,

⇒ (π/4, 7π/4).

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Here, The given equation is;

sin(5x - π) = (√2)/2

Now, We can write 2 as √2 × √2

So, We get;

sin(5x - π) = √2/√2*√2

sin(5x - π) = 1/√2

Taking sin⁻¹ on both side,

sin⁻¹ (sin(5x - π)) = sin⁻¹ (1/√2)

5x - π = sin⁻¹ (1/√2)

Hence, From the trigonometry table we know that sin⁻¹ (1/√2) = π/4

Thus,

5x - π = π/4

5x = π + π/4

5x = 5/4π

Divide by 5 on both side, we get

x = π/4

Now, since x < 2π, then it means it is in the fourth quadrant. Thus;

x = 7π/4

So, the two of the possible solutions to the equation sin(5x - π) = (√2)/2 is (π/4, 7π/4).

Answer:

Height of the pine tree = 60 in.

Step-by-step explanation:

Since, triangle formed by the tip of the tree and tip of the shadow of the tree will be similar to each other,

By the property of similarity, corresponding sides of the similar triangles will be proportional.

[tex]\frac{x}{20}=\frac{36}{d}[/tex]

If d = 12 inches,

[tex]\frac{x}{20}=\frac{36}{12}[/tex]

x = [tex]\frac{20\times 36}{12}[/tex]

x = 60 in.

Therefore, height of the pine tree will be 60 in.

okay so it says Sophia's friend has saved $118 so she already knows she has $118 and then the next step is to figure out about Part B so she does not know how many songs you can afford to buy so the expression in Part B whatever the expression is if you figured out the answer to Part B and there's a number what you want to do what you would want to divide that number into 118 to see how how many equal groups you can make and you don't want to go overboard 18 so what you would want to do it if you would want to do if you figure out the number to expression be in the boring part B they don't want to take that and keep making a go go to that until you reach 118 and then you would get your total

Answer:

30%

Step-by-step explanation:

I apologize if I am incorrect

Answer:

70%

Step-by-step explanation:

set up an equation for the word problem that looks like this: 50x = 35

and solve by dividing both sides by 35

50x ÷ 50 = x

35 ÷ 50 = .7

.7 = 70%

x = 70%
