find the ratio of 4 inches to 3 yards

Answers

Answer 1

every 1 unit of 4 inches, there are 27 units of 3 yards. It's important to note that ratios represent a proportional relationship between two quantities and do not necessarily represent the actual values themselves.

How to solve ratio?

To find the ratio of 4 inches to 3 yards, we need to convert both measurements to a common unit of measurement.

Firstly, let's convert the 3 yards to inches, since inches are already given. There are 36 inches in a yard (3 feet in a yard, and 12 inches in a foot), so:

3 yards = 3 x 36 inches = 108 inches

Now we can compare the two measurements:

Ratio of 4 inches to 108 inches = 4/108

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 4 in this case:

4/108 = 1/27

So, the ratio of 4 inches to 3 yards is 1:27.

This means that for every 1 unit of 4 inches, there are 27 units of 3 yards. It's important to note that ratios represent a proportional relationship between two quantities and do not necessarily represent the actual values themselves.

Answers

On solving the provided question we cans ay that Thus the probability that Capt. Rigg will wait at least 5 minutes to land the plane following the announcement is 1 - 0.5 = 0.5.

What is probability?

Probability is a measure of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing a rare event and 1 representing an inescapable event. Switching a fair coin and coin flips has a chance of 0.5 or 50% because there are two equally likely outcomes. (Heads or tails). Probabilistic theory is an area of mathematics that studies random events rather than their attributes. It is applied in many fields, including statistics, economics, science, and engineering.

probability Capt. Rigg has at least 5 minutes after the announcement to land the plane, which is equal to the area under the probability density function of the uniform distribution ranging from 5 to 25 minutes. A uniform distribution's density function on the interval [a, b] is f(x) = 1/(b-a) for an x b and f(x) = 0 otherwise.

Because a = 5 and b = 25 in this case, the density function is f(x) = 1/20 for 5 x 25, and f(x) = 0 otherwise. From 5 to 25, the area covered by this function is:

dx = [5,25] 1/20 dx = [x/20] from 5 to 25 = (25-5)/20 = 1.

Thus the likelihood that Capt. Rigg will wait at least 5 minutes to land the plane following the announcement is 1 - 0.5 = 0.5.

use double angle identity to simplify the following expression
tan 12 degrees/1-tan^2 12 degrees

Answers

Answer: We can use the double angle identity for tangent, which states that:

tan(2θ) = 2tan(θ) / (1 - tan²(θ))

to simplify the expression.

Let θ = 6 degrees, then we have:

tan(2θ) = tan(12 degrees)

tan(2θ) = 2tan(θ) / (1 - tan²(θ))

tan(12 degrees) = 2tan(6 degrees) / (1 - tan²(6 degrees))

We can use the tangent half-angle identity to find tan(6 degrees), which states that:

tan(θ/2) = sin(θ) / (1 + cos(θ))

Letting θ = 12 degrees, we get:

tan(6 degrees) = sin(12 degrees) / (1 + cos(12 degrees))

We can then use the double angle identity for sine, which states that:

sin(2θ) = 2sin(θ)cos(θ)

to simplify sin(12 degrees). Letting θ = 6 degrees, we get:

sin(12 degrees) = 2sin(6 degrees)cos(6 degrees)

We can use the half-angle identity for cosine to find cos(6 degrees), which states that:

cos(θ/2) = √((1 + cos(θ)) / 2)

Letting θ = 12 degrees, we get:

cos(6 degrees) = √((1 + cos(12 degrees)) / 2)

Substituting these values into the original expression, we get:

tan(12 degrees) = 2tan(6 degrees) / (1 - tan²(6 degrees))

tan(12 degrees) = 2(sin(12 degrees) / (1 + cos(12 degrees))) / (1 - (sin²(12 degrees) / (1 + cos(12 degrees))²))

tan(12 degrees) = 2(2sin(6 degrees)cos(6 degrees) / (1 + cos(12 degrees))) / (1 - (4sin²(6 degrees)cos²(6 degrees) / (1 + cos(12 degrees))²))

tan(12 degrees) = (4sin(6 degrees)cos(6 degrees)) / (1 + cos(12 degrees) - 4sin²(6 degrees)cos²(6 degrees))

This is the simplified expression using the double angle identity.

Vusi has been told that he should increase the overall total value of all of the eight parts by 10%, to reflect the effect of price inflation and the devaluation of the rand over the six month period when the production line was not operational.

Answers

By answering the presented question, we may conclude that As a result, equation the new total value of all eight pieces, after the 10% rise, is R132.

What is equation?

In mathematics, an equation is a statement that states the equivalence of two expressions. An equation is made up of two sides separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" contends that the phrase "2x Plus 3" equals the number "9." The purpose of equation solving is to identify the value or values of the variable(s) that will make the equation true. Simple or complicated equations, regular or nonlinear, with one or more components are all possible. For example, in the equation "x2 + 2x - 3 = 0," the variable x is raised to the second power. Lines are utilized in many areas of mathematics, including algebra, calculus, and geometry.

Multiply the current total value by 1.1 to boost the overall total value of all eight components by 10%.

To begin, compute the current total value of all eight parts:

R16 + R24 + R30 + R18 + R12 + R10 + R16 + R14 = Total value

R120 is the total value.

Let us now boost the total amount by 10%:

Total new value = R120 x 1.1

R132 is the new total value.

As a result, the new total value of all eight pieces, after the 10% rise, is R132.

A swimmer dives into a lake and swims to the surface in a parabolic path. path of the swimmer can be modeled by the equation
h (t) = t - 4t-where h is the height in
feet, and t is the time in seconds.
Complete the statement.
The diver will reach the surface of the water
after seconds.

Answers

Answer:

the diver will reach the surface of the water after 1/4 seconds.

Step-by-step explanation:

To find when the swimmer reaches the surface of the water, we need to set h(t) to zero since the surface of the water is at a height of zero feet.

0 = t - 4t^2

Simplifying the equation, we get:

4t^2 = t

4t^2 - t = 0

t(4t - 1) = 0

So, either t = 0 (which corresponds to the initial time when the swimmer is at the surface) or 4t - 1 = 0. Solving for t, we get:

4t - 1 = 0

4t = 1

t = 1/4

Therefore, the diver will reach the surface of the water after 1/4 seconds.

Jane is training for a triathlon. After swimming a few laps, she leaves the health club and bikes 16 miles south. She then runs 12 miles west. Her trainer bikes from the health club to meet Jane at the end of her run.




How much farther does Jane travel than her trainer? Answer the questions to find out.



1. What is the total distance Jane travels biking and running? Include units with your answer. (2 points)









2. Use the Pythagorean theorem to write an equation for the distance Jane's trainer bikes. (2 points)





3. Solve your equation to find the distance Jane's trainer bikes. Show your work. (3 points)



4. How much farther does Jane travel than her trainer? (3 points)

Answers

Answer:

1 The total distance Jane travels biking and running is the hypotenuse of a right triangle with legs 16 miles and 12 miles. Using the Pythagorean theorem, we can find this distance:

distance = sqrt(16^2 + 12^2) = sqrt(256 + 144) = sqrt(400) = 20 miles

So Jane travels a total of 20 miles.

2 The distance Jane's trainer bikes is the distance from the health club to the point where he meets Jane. Let's call this distance x. We can represent this with the following right triangle:

css

Copy code

        A (health club)

        |

        |

        | x

        |

        |

B (meeting point)

where A and B are points on a coordinate plane, and the x-axis represents the direction Jane runs.

Using the Pythagorean theorem, we can write:

x^2 + 12^2 = d^2

where d is the distance from the health club to the end of Jane's run. We know that d = 20, so we can substitute:

x^2 + 12^2 = 20^2

3. Solving for x:

x^2 + 144 = 400

x^2 = 256

x = sqrt(256) = 16

So Jane's trainer bikes 16 miles.

4 Jane travels 20 - 16 = 4 miles farther than her trainer.

Each of 17 mothers-to-be received 3D ultrasound scans, which showed that 8 of them will give birth togirls. Assuming that simultaneous births do not happen
(i.e., babies are born one after another), what is the
probability that the first two babies that are born
happen to be boys?

Answers

Since each birth is independent and the probability of giving birth to a boy or a girl is equal, the probability of giving birth to a boy is 0.5, and the probability of giving birth to a girl is also 0.5.

The probability of the first baby being a boy is 0.5. The probability of the second baby also being a boy is also 0.5, since the gender of one baby does not affect the gender of the other.

The probability of both events occurring together (i.e., the probability of having two boys in a row) is equal to the product of their probabilities. Thus, the probability of having two boys in a row is 0.5 x 0.5 = 0.25 or 25%.

Since simultaneous births do not happen (i.e., babies are born one after another), the probability of the first two babies that are born being boys is the same as the probability of any two specific babies being boys. Therefore, the probability of the first two babies being boys is 0.25 or 25%.

Note that the fact that 8 out of the 17 mothers will give birth to girls is irrelevant to this particular probability problem, since we are only interested in the probability of two specific babies being boys.

Suppose that the distribution of scores of 1,000 students who take a standardized intelligence test is a normal distribution. Also, suppose that the​ distribution's mean is 470 and its standard deviation is 10.

Answers

This information can be used to understand the performance of the students and Evaluate their scores in relation to the overall group.

Suppose that the distribution of scores of 1,000 students who take a standardized intelligence test is a normal distribution. In this scenario, the distribution's mean is 470 and its standard deviation is 10.

A normal distribution, also known as a Gaussian distribution or bell curve, is a symmetric distribution where the majority of the data falls around the mean value. In this case, the mean score is 470, which represents the average intelligence score for the 1,000 students. The standard deviation, which is 10 in this case, measures the dispersion or spread of the data around the mean.

To interpret the scores, we can use the empirical rule, which states that approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.

Applying this rule:
- About 68% of the students scored between 460 (470-10) and 480 (470+10).
- Approximately 95% of the students scored between 450 (470-2*10) and 490 (470+2*10).
- Around 99.7% of the students scored between 440 (470-3*10) and 500 (470+3*10).

Despite their confidence in their thinking, beliefs, and actions, European countries in power during this time frame were often wrong in their assumptions about the superiority of their culture and the legitimacy of their actions towards other nations and peoples.

Why were the European very wrong with their thought?

European countries in power during this time frame, particularly in the 19th and early 20th centuries, believed in the concept of imperialism and the "civilizing mission" of spreading their culture and values to other parts of the world. This often led to the exploitation and oppression of colonized peoples, as well as the imposition of Western values on non-Western cultures.

However, these assumptions about the superiority of Western culture were flawed and based on a Eurocentric view of the world. Additionally, many European powers engaged in brutal and violent actions, such as the forced removal of Indigenous peoples from their lands, the use of slavery and forced labor, and the exploitation of natural resources.

The outside temperature is approximately 78.03°F, the sales are estimated to be $1,993.33.

Define temperature

It refers to a physical property of matter that reflects how hot or cold an object is relative to other objects or a standard scale. Temperature is typically measured in units such as Celsius (°C), Fahrenheit (°F), or Kelvin (K).

When the outside temperature is 30°F, the sales are estimated to be:

y = 32.92(30) - 572.87

y = 987.60 - 572.87

y = $414.73

Therefore, when the outside temperature is 30°F, the sales are estimated to be $414.73.

When the outside temperature is x, the sales are estimated to be $1,993.33, we can solve for x as follows:

1,993.33 = 32.92x - 572.87

2,566.20 = 32.92x

x ≈ 78.03°F

Therefore, when the outside temperature is approximately 78.03°F, the sales are estimated to be $1,993.33.

A suitable elimination strategy will multiply one of the equations by a value that makes this ratio -1. Let's look at the choices.

A. Bottom by -3/2

To find the vertex, we usually use the formula -b/2a to find the x-vertex. So, the x-vertex would be:

-(-4)/2

4/2

2

The y-vertex can be found by substituting the x-vertex back into the equation. So:

y=(2)² -4(2) + 5

y= 4-8+5

y= -4 + 5

y= 1

So, we found that our vertex is (8,1)

Because we see that our "a" value from our quadratic equation is positive, this tells us that the graph opens upwards. We know our vertex is higher than our x-axis line, so there will be no x-intercepts.

The y-intercept is found when the x-value equals to 0. So, inserting this into the equation, we get :

y=(0)² - 0 +5

y= 5

So, we have found our y-intercept as (0, 5)

The graph you could've made would've been using the vertex and the y-intercept and connecting those points for one side of the quadratic graph. The other side would require an integer point for more accuracies, and I believe that the point (3,2) also works.

So, using the points (3,2), (0,5), and (8,1), we can make a graph!

Megan earned £158,900 before tax last year. Her total tax bill was £53,205, which was calculated by finding the tax on each part of her earnings within different tax brackets and adding them up.

What is rate?

A rate is a measure of how one quantity changes in relation to another quantity. It is usually expressed as a ratio of two different units, such as miles per hour or dollars per pound. Rates can be used to compare different values and to make predictions about future outcomes. Common examples of rates include interest rates, exchange rates, and tax rates.

According to the given information:

To calculate Megan's tax bill, we need to find the tax on each part of her earnings that falls within the different tax brackets, and then add them up.

For the first £11,000 of Megan's earnings, there is no tax.

For the next £32,000 of Megan's earnings (from £11,001 to £43,000), the tax rate is 20%, so the tax on this portion of her earnings is:

0.2 x 32,000 = £6,400

For the next £107,000 of Megan's earnings (from £43,001 to £150,000), the tax rate is 40%, so the tax on this portion of her earnings is:

0.4 x 107,000 = £42,800

For the portion of Megan's earnings over £150,000, the tax rate is 45%, so the tax on this portion of her earnings is:

0.45 x 8,900 = £4,005

Therefore, Megan's total tax bill is:

£6,400 + £42,800 + £4,005 = £53,205

So, Megan paid £53,205 in total tax for the last year.

Therefore, Megan earned £158,900 before tax last year. Her total tax bill was £53,205, which was calculated by finding the tax on each part of her earnings within different tax brackets and adding them up.

The diameter of the semicircle is equal to the width of the paperboard, which is 12 inches. So, the radius of the semicircle is half of the diameter, which is 6 inches.

The perimeter of the remaining part will be the sum of the length of the paperboard and the two straight sides of the semicircle.

The length of the paperboard is 20 inches, and the two straight sides of the semicircle are equal to the diameter of the semicircle, which is 12 inches. So, the perimeter of the remaining part is:

P = 20 + 12 + 12 = 44 inches

However, we also need to subtract the length of the curved part of the semicircle from the perimeter. The length of the semicircle can be found using the formula:

C = πr

where C is the circumference of the semicircle and r is the radius.

Since we have a semicircle, we need to divide the circumference by 2. So, the length of the curved part of the semicircle is:

C/2 = (π x 6) / 2 = 9.42 inches (rounded to two decimal places)

Therefore, the perimeter of the remaining part is:

P = 44 - 9.42 = 34.58 inches (rounded to two decimal places)

So, the perimeter of the remaining paperboard is 34.58 inches.

the diameter of each tire on a vehicle is 32 inches. if the tires are moving at a rate of 800 revolutions per minute, find the linear speed of the vehicle in miles per hour.

Answers

Answer:

The linear speed of the vehicle is approximately 0.798 miles per hour.

Step-by-step explanation:

The circumference of a tire is given by the formula C = πd, where d is the diameter of the tire. So, the circumference of each tire is:

C = πd = π(32 inches) ≈ 100.53 inches

Now, to find the distance that the vehicle travels in one revolution of each tire, we use the circumference formula again:

distance traveled in one revolution = circumference of the tire = 100.53 inches

Since the tires are rotating at a rate of 800 revolutions per minute, the vehicle travels a distance of:

distance traveled in one minute = distance traveled in one revolution × number of revolutions per minute

= 100.53 inches/revolution × 800 revolutions/minute

= 80424 inches/minute

To convert this to miles per hour, we need to divide by the number of inches per mile and the number of minutes per hour:

speed = (80424 inches/minute) × (1 mile/63360 inches) × (60 minutes/1 hour)

≈ 0.798 miles/hour

Therefore, the linear speed of the vehicle is approximately 0.798 miles per hour.

How to deal with trigonometric equation?

Trigonometry is the study of angles and the angular relationships between planar and three-dimensional figures. The cosecant, cosine, cotangent, secant, sine, and tangent are the trigonometric functions—also known as the circular functions—that make up trigonometry.

According to question:

The cofunction of sine is cosine, which means:

[tex]$\begin{equation}\csc(\theta) = \frac{1}{\sin(\theta)} = \frac{1}{\cos\left(\frac{\pi}{2}-\theta\right)}\end{equation}[/tex]

Therefore, we can express [tex]$\csc\left(\frac{4\pi}{9}\right)$[/tex] as:

[tex]$\begin{equation}\csc\left(\frac{4\pi}{9}\right) = \frac{1}{\sin\left(\frac{4\pi}{9}\right)} = \frac{1}{\cos\left(\frac{\pi}{2}-\frac{4\pi}{9}\right)}\end{equation}[/tex]

Simplifying the argument of the cosine function:

[tex]$\begin{equation}\frac{\pi}{2}-\frac{4\pi}{9} = \frac{5\pi}{18}\end{equation}[/tex]

Substituting this back into the equation, we get:

[tex]$\begin{equation}\csc\left(\frac{4\pi}{9}\right) = \frac{1}{\cos\left(\frac{5\pi}{18}\right)}\end{equation}[/tex]

Therefore, an expression equal to [tex]$\csc\left(\frac{4\pi}{9}\right)$[/tex] using a cofunction is:

[tex]\begin{equation}\frac{1}{\cos\left(\frac{5\pi}{18}\right)}\end{equation}[/tex]

Write the expression in terms of sine and cosine, and simplify so that no quotients appear in the final expression.
tan θ / sec θ​

Answers

Answer:

tan θ / sec θ = sin θ

Step-by-step explanation:

We know that secant is the reciprocal of cosine. Therefore, we can write:

sec θ = 1/cos θ

Substituting this in the given expression, we get:

tan θ / sec θ = tan θ / (1/cos θ)

Multiplying by cos θ/cos θ to simplify the expression, we get:

tan θ / sec θ = (tan θ cos θ) / 1

We know that the tangent of an angle is equal to the sine of the angle divided by the cosine of the angle. Therefore:

tan θ = sin θ / cos θ

Substituting this in the expression above, we get:

tan θ / sec θ = (sin θ / cos θ) cos θ

Simplifying the expression further, we get:

tan θ / sec θ = sin θ

Therefore, the expression in terms of sine and cosine, simplified so that no quotients appear in the final expression, is:

tan θ / sec θ = sin θ

Alexander built a toy box in the shape of a rectangular prism with an open top. The diagram below shows the toy box and the net of the toy box. NET OF TOY BOX is 14 cm 10 cm 9 cm What is the surface area, in square centimeters, of the toy box?

Answers

The surface area of the toy box is 712 square centimeters.

Describe Surface Area?

Surface area is the measure of the total area that the surface of an object occupies. In other words, it is the sum of the areas of all the faces or surfaces of the object.

For example, consider a rectangular prism with dimensions length (l), width (w), and height (h). The surface area of this object would be the sum of the areas of all six faces, which are:

Two rectangular faces with area lw

Two rectangular faces with area wh

Two rectangular faces with area lh

So the total surface area of the rectangular prism would be:

Surface area = 2lw + 2wh + 2lh

The concept of surface area is useful in various fields, such as architecture, engineering, and physics. For example, in construction, knowing the surface area of a structure can help estimate the amount of materials needed for construction, such as paint or roofing tiles. In physics, surface area is important in determining the heat transfer and rate of reaction of a substance.

The surface area of the toy box can be found by summing the areas of its six faces. From the given net, we can see that the toy box has dimensions of 14 cm by 10 cm by 9 cm.

The top and bottom faces have areas of 14 cm × 10 cm = 140 cm² each.

The front and back faces have areas of 14 cm × 9 cm = 126 cm² each.

The left and right faces have areas of 10 cm × 9 cm = 90 cm² each.

Therefore, the total surface area is:

2(140 cm²) + 2(126 cm²) + 2(90 cm²) = 280 cm² + 252 cm² + 180 cm² = 712 cm²

Thus, the surface area of the toy box is 712 square centimeters.

Answers

Selecting the first tile (1st) and selecting the secοnd tile (2nd) are independent events.

The prοbability οf selecting an even number οn a single draw is 2/5 οr 0.4, as there are twο even numbers (2 and 4) οut οf a tοtal οf five pοssible numbers.

Since the events are independent, the prοbability οf selecting an even number οn bοth draws is the prοduct οf the prοbabilities οf selecting an even number οn each draw:

P(bοth even) = P(even οn first) × P(even οn secοnd) = 0.4 × 0.4 = 0.16

Allison uses 3
inches of fabric to make a bookmark. She buys 412
feet of fabric.

How many bookmarks can Allison make with 412
feet of fabric?

Answers

Allison can make 1648 bookmarks with 412 feet of fabric.

First of all, the total length of fabric, and the length of each bookmark have different units.

Therefore, we convert fabric length into inches.

1 foot = 12 inches

∴ 412 feet = 412 × 12 inches

                 = 4944 inches.

Now,

length of each bookmark = 3 inches (given)

Total length of fabric in inches = 4944 inches

∴ Total number of bookmarks = 4944 ÷ 3

                                                  = 1648

Hence we find that the total number of bookmarks that Allison can make from 412 feet of fabric is 1648.
