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:

Answer:

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

Answer: Angle aeb

Step-by-step explanation: To be supplementary, the angle(s) must add up to 180. Angle AEB and angle DEA add to 180. Another way to find this is to find the angle that the angle is adjacent to in a straight line.

Answer: Angle EGF

Step-by-step explanation: Angle EGF is complementary to FGA because the two angles add up to 90 degrees, which is what it means to be complementary.

Step-by-step explanation:

5x² - 19x - 4

Answer:

The lower quartile corresponds to the 25th percentile of the data set. To find the maximum value for the lower quartile, we need to find the largest number that is at or below the 25th percentile.

The range of the numbers that the random number generator can pick is 69 - 7 + 1 = 63. The 25th percentile corresponds to the value that is 25% of the way through this range, which is:

0.25 * 63 = 15.75

Since we can't pick a fractional number, we need to round down to 15. Therefore, the maximum value for the lower quartile is 15.

The measure of the angle ADC is: 20°

The parameters are given as:

∠ABC = 40°

∠ADC = ?

We know from circle geometry that:

Angle subtended at the center is twice the angle subtended at the circumference.

Therefore:

∠ABC = 2 x ∠ADC

On substituting the value we get:

40° = 2 * ∠ADC

∠ADC = 20°

Therefore, the measure of the angle ADC is 20°

Answer:

Therefore, the area of a small family farm in square feet is 9,923,640.

Step-by-step explanation:

a. To convert acres to square miles, we divide the number of acres by 640:

231 acres / 640 acres/square mile = 0.36 square miles

Therefore, the area of a small family farm in square miles is 0.36.

b. To convert acres to square feet, we first need to convert acres to square yards (since there are 9 square feet in a square yard):

231 acres x 4840 square yards/acre x 9 square feet/square yard = 9,923,640 square feet

Therefore, the area of a small family farm in square feet is 9,923,640.

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%.

  x+3 . . . . if x > 5

Step-by-step explanation:

You want the meaning of |x+3| if x > 5.

The absolute value function is a piecewise defined function:

  [tex]y=|x|=\begin{cases}-x&\text{for }x < 0\\x&\text{for }x\ge0\end{cases}[/tex]

The expression (x+3) is zero when x=-3. So, your absolute value function will have the piecewise definition ...

  [tex]|x+3|=\begin{cases}-(x+3)&\text{for }x < -3\\x+3&\text{for }x\ge-3\end{cases}[/tex]

You are interested in the value for x > 5, which is definitely greater than -3. That means only the second part of this definition is applicable.

Answer:

We can use the formula:

average speed = total distance / total time

To find the total distance, we add the distances for each event:

total distance = 1.5 km (swimming) + 40 km (cycling) + 1 km (running) = 42.5 km

To find the total time, we add the times for each event:

time for swimming = distance / speed = 1.5 km / 2.5 km/h = 0.6 hours

time for cycling = 40 km / 12 km/h = 3.33 hours

time for running = 1 km / 9 km/h = 0.11 hours

total time = 0.6 hours + 3.33 hours + 0.11 hours = 4.04 hours

Now we can calculate the average speed:

average speed = total distance / total time = 42.5 km / 4.04 hours ≈ 10.52 km/h

Therefore, Farhan's average speed for the entire competition is approximately 10.52 km/h.

The diameter of the lake is 6.2 m.

The diameter is the distance from one edge of the circle to the next across the center.

The diameter can be determined given the circumference and pi, since circumference is pi x diameter.

The number of times Gracie walks around the circular lake = 15 times

The total distance covered by the walk = 2,178 meters

The circumference (the distance around the edge of the circular lake) is 145.2 m (2,178 ÷ 15).

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%.

The numbers are characterized as rational and irrational numbers as below

1. 3.2 x 10³ - R (Rational)

Rational numbers harmonized with a fraction of two integers where the denominator must not be zero. In simpler terms, it can be conveyed as p/q whereby both "p" and "q" are integers while "q" is unequal to zero.

As opposed to rational numbers, irrational ones cannot be expressed in a fraction or quotient of two integers. It's not possible to write them down in terms of the figure p/q whereby "p" and "q" are integers, differing from one another, and "q" is also inequivalent to zero.

Answer: 1204 cm²

Step-by-step explanation:

The upper bound of the area of a page would be the area of a rectangle with the upper bound of the length and width measurements.

Given that each page of the newspaper is a rectangle measuring 43 cm by 28 cm, both correct to the nearest centimetre, the upper bound of the length would be 43.5 cm (since we round up to the nearest centimetre) and the upper bound of the width would be 28.5 cm.

Therefore, the upper bound of the area of a page would be:

43.5 cm x 28.5 cm = 1240.25 cm²

Rounding this value to the nearest whole number, we get:

1204 cm²

So, the upper bound of the area of a page is 1204 cm².
