What is the percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

To find the retail selling price of the keyboard, we need to add the markup to the cost of the keyboard.

The markup of 150% means that the retailer is adding 150% of the cost to the selling price.

To calculate this, we can first find the dollar amount of the markup:

Markup = 150% of $25

Markup = 0.5 * 150 * $25

Markup = $18.75

This means that the retailer is adding $18.75 to the cost of the keyboard to get the selling price. To find the selling price, we can add the markup to the cost:

Selling price = Cost + Markup

Selling price = $25 + $18.75

Selling price = $43.75

Therefore, the retail selling price of the keyboard is $43.75.

Step-by-step explanation:

so for figure a:

we can find x by using sin which is sin = opposite/hypotenuse so

- sin30= x/10cm(sin30 is equivalent to 1/2 or 0.5)

- 0.5= x/10cm or 1/2=x/10cm (i'm gonna use the 2nd option)

- 10cm * 1/2=x

-x=5cm

and for figure b:

here we also use sin

- sin 50= x/8cm (sin 50 is equivalent to 0.7660 )

- 0.7660= x/ 8cm

-0.7660 * 8cm=x

- x= 6.128cm and when estimated x= 6cm

The probability that an adult chosen at random will be willing to change their diet is 0.29 or 29%.

what is probability?

In general terms, probability is the measure of the likelihood or chance of an event occurring. It is a mathematical concept that is used to quantify uncertainty or randomness in various situations.

In formal terms, probability is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes in an event. It is usually represented as a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

The probability of an adult being willing to change their diet can be calculated using the given information as follows:

Probability of an adult being willing to change diet = Number of adults willing to change / Total number of adults

Total number of adults = 400 (as given in the question)

Number of adults willing to change = 116 (as given in the question)

Therefore, the probability of an adult being willing to change their diet can be calculated as:

Probability = 116/400

Probability = 0.29 or 29%

So, the probability that an adult chosen at random will be willing to change their diet is 0.29 or 29%.

The equation for its altitude h​ (in m) as a function of time t is h(t) = h₀ x 1000 - rt and the graph of the equation is illustrated below.

Let's begin by defining our variables. We know that the initial altitude of the airplane is given as h₀, which is in km. We also know that the rate at which the altitude decreases is given as r, which is in m/min. Our objective is to determine the altitude h of the airplane at any given time t, in minutes, during the descent.

To find the equation for the altitude of the airplane, we need to first convert the initial altitude from km to m. This can be done by multiplying h₀ by 1000. Therefore, the initial altitude in meters is h₀ × 1000.

Finally, we can find the equation for the altitude of the airplane by subtracting the amount that the altitude has decreased from the initial altitude. This gives us the following equation:

h(t) = h₀ × 1000 - rt

where h(t) is the altitude of the airplane at time t, h₀ is the initial altitude in km, r is the rate of descent in m/min, and t is the time in minutes.

To sketch the graph of this equation, we can plot altitude on the y-axis and time on the x-axis.  Then we get the graph like the following.

Two lines that are in general position divide a plane into four regions or parts.

When two lines intersect at a point, they divide the plane into four distinct regions, called quadrants. However, if the two lines are parallel, they do not intersect, and the plane is divided into only two regions, called half-planes.

In general position, two lines in a plane have different slopes and different y-intercepts, which means that they are neither parallel nor coincident. Therefore, the two lines must intersect at a point, dividing the plane into four regions.

Answer: 5.1%

Step-by-step explanation:

The formula for calculating the effective annual yield when the interest is compounded semiannually is given by:

(1 + (r/n))^n - 1

where r is the annual interest rate and n is the number of times the interest is compounded in a year.

In this case, r = 5% and n = 2 (since the interest is compounded semiannually). Substituting these values into the formula, we get:

(1 + (0.05/2))^2 - 1

= (1.025)^2 - 1

= 1.050625 - 1

= 0.050625

Multiplying this value by 100 gives the effective annual yield as a percentage:

0.050625 x 100 = 5.0625%

Rounding this to the nearest tenth of a percent, we get:

Effective annual yield = 5.1%

Therefore, the effective annual yield for the given savings account, rounded to the nearest tenth of a percent, is 5.1%.

According to the given information:

The expression "[tex](\frac{3}{4} )^{2}[/tex]" represents the fraction "3/4" raised to the power of "-2". In mathematical notation, this is written as "[tex](\frac{3}{4} )^{-2}[/tex]".

To calculate this value, we can use the rule that a negative exponent is equivalent to taking the reciprocal of the base raised to the positive exponent. Therefore, "[tex](\frac{3}{4} )^{-2}[/tex]" is equal to the reciprocal of "3/4" raised to the power of "2", or "[tex]\frac{1}{(\frac{3}{4} )^{2}}[/tex]".

Evaluating this expression, we get:

[tex](\frac{3}{4} )^{-2}[/tex]= [tex]\frac{1}{(\frac{3}{4} )^{2}}[/tex] = [tex]\frac{1}{(\frac{9}{6})^{2} }[/tex]= 16/9

If "NE" and "TE" are tangents of circle, then length of segment NE is 53 units.

We find the length of the segment "NE" by using the fact that tangents drawn to a circle from an external point are equal in length.

So, We have,

⇒ NE = TE       ...(because they are tangents to the same circle from the same external point E),

So we can set the "two-expressions" of tangent equal to each other:

We get,

⇒ 13x - 12 = 7x + 18,

⇒ 6x - 12 = 18,

⇒ 6x = 30,

⇒ x = 5,

now, we substitute the value of x in "NE", to find the length of segment NE.

We get,

⇒ NE = 13x - 12,

⇒ NE = 13(5) - 12,

⇒ NE = 65 - 12,

(b) The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.

From the question, we have the following parameters that can be used in our computation:

f(x) = x²

g(x) = (1/5x)²

The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.

To see this, we can rewrite g(x) as g(x) = (1/5)²(x²) = (1/5²)f(x).

This means that g(x) is equal to f(x) scaled vertically by a factor of 5² = 25.

The amount spent on advertising that will yield a monthly profit of $9,000 is $8.57.

Profit is the amount of money or financial gain that a business or an individual makes after deducting all the expenses and costs associated with producing or providing a product or service.

According to the model, the profit P (in dollars) is dependent on the sum x (in dollars) that the business invests in advertising:

P = 130x² - 550

We want to find the amount spent on advertising that will yield a monthly profit of $9,000. In other words, we want to solve for x when P = 9000:

130x² - 550 = 9000

Adding 550 to both sides, we get:

130x² = 9550

Dividing both sides by 130, we get:

x² = 73.46

x = ±8.57

Since we are dealing with a real-world scenario, the amount spent on advertising must be a positive value. Therefore, we take the positive root:

x = 8.57

Therefore, the amount spent on advertising that will yield a monthly profit of $9,000 is $8.57.

Main body:

A parametric curve is a function expressed in components form, such that;

x = f(t) , y = g(t).

The length of a parametric curve on the interval a ≤ t ≤ b is given by the definite integral :

L =  [tex]\int\limits^a_b {\sqrt{\frac{dx}{dt}^2 + {\frac{dy}{dt}^2 } } } \, dx[/tex]

Let's begin by getting the first derivative of the components of the function with respect to the variable t.

x = e^t - t  

dx / dt = e^t−1

And, y = 4 e^t/2

dy /dt = 2 e^t/2

Substitute the derivatives into the following definite integral which computes the length of the parametric curve on the interval

[a,b]=[0,2].

L =  [tex]\int\limits^a_b {\sqrt{\frac{dx}{dt}^2 + {\frac{dy}{dt}^2 } } } \, dx[/tex]

L=  [tex]\int\limits^2_0 {\sqrt{\ (e^t - 1)^2 + ({\(2e^{t/2}) ^2 } } } \, dx[/tex]

L = [tex]\int\limits^2_0 {e^t - 1} \, dx[/tex]

Evaluate the solution at the limits of integration to get the length.

L = (e² - 1 )- (e⁰ - 1)

L = e² - 1 - 1 + 1

L= e² - 1

Hence , length of the curve is e² - 1 .

Answer:

Step-by-step explanation:

To solve this problem, we can use the simple interest formula:

I = P*r*t

where I is the interest earned, P is the principal (the initial investment), r is the interest rate (as a decimal), and t is the time (in years).

Here, we want to find P, so we'll rearrange the formula:

P = I/(r*t)

We know that the final value of the investment (including interest) is $15,500, and the time is 10 months (or 10/12 years). We can plug in the numbers:

I = $15,500 - P

r = 0.02

t = 10/12

P = (15,500 - P)/(0.02*(10/12))

P = (15,500 - P)/(0.1667)

P = 93,000 - 6P

7P = 93,000

P = $13,285.71

Therefore, you should pay $13,285.71 for the note if you want to earn 2% annual simple interest and have it be worth $15,500 in 10 months.
