An open box is to be constructed from a square piece of sheet metal by removing a square of side 3 feet from each corner and turning up the edges. If the box is to hold 300 cubic​ feet, what should be the dimensions of the sheet​ metal?

Answers

Answer 1

If an open box is to be constructed from a square piece of sheet metal by removing a square of side 3 feet from each corner and turning up the edges. the dimensions of the sheet​ metal is 16 feet.

How to find the dimension?

Let x represent the dimension of the sheet metal

So,

Volume =3×(x-2×3)×(x-2×3) = 300

Volume =3×(x-6)×(x-6) = 300

(x -6)² = 300/3 = 100

x-6 = √100 =10

x = 10 +6

x = 16 feet

Therefore the dimensions of the sheet​ metal is 16 feet

The sum of the base and the height of a triangle is 10 cm. Find the dimensions for which the area is a maximum.

Answers

The maximum area of a triangle with a base and height of 10 cm is 50 cm^2. The dimensions for this would be a base of 5 cm and a height of 5 cm.

1. The area of a triangle is calculated by taking the base multiplied by the height, then dividing by 2.

2. Since the sum of the base and the height of the triangle is 10 cm, the base and the height must be equal.

3. Therefore, the base and the height are both 5 cm, and the area of the triangle is (5 cm * 5 cm) / 2, which equals to 50 cm^2.

The average mass of apple of 2 bags A and B is 6.4kg. Given that bag A contains 0.9kg of apple than bag B, find the mass of apple in bag B

Answers

Using the formula for the average value between two numbers, we will see that bag B weighs 11.9 kg

How to find the weight of bag B?

If we have two values x and y, the average value between these two is given by the formula below.

average = (x + y)/2

Here we know that the average between the wheights of bags A and B is 6.4 kg, and A = 0.9kg

Then we can write the equation:

6.4kg = (B + 0.9kg)/2

We can solve that equation for B to get:

2*6.4kg = B + 0.9kg

12.8kg - 0.9kg = B

11.9kg = B

Bag B weighs 11.9 kilograms.

What are geometric shapes in mathematics?

In Mathematics, Geometric shapes are the figures which demonstrate the shape of the objects we see in our everyday life. In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes.

Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as a square, circle, etc. Irregular shapes are asymmetrical. They are also called freeform shapes or organic shapes. For example, the shape of a tree is irregular or organic.

In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc.  In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can observe all these shapes in our daily existence also. For example books (cuboid shape), glasses (cylindrical shape), traffic cones (conical shape) and so on.

Now

As the scale factor for similar shapes V and U is 5:1.

Then their area should also be in same ratio.

The Institute of Medicine also calculated the health gap between the US and other countries, which was defined as the difference between the health outcomes of the US and the health outcomes of the other countries. This gap was calculated by subtracting the US health outcome rate from the average of the other countries' health outcome rates. For example, to calculate the infant mortality gap, the infant mortality rate in the US (5.8 deaths per 1,000 live births in 2018) was subtracted from the average infant mortality rate of the other countries (3.5 deaths per 1,000 live births). This resulted in a health gap of 2.3 deaths per 1,000 live births.

the value of the difference between the terms increases by 4 as the series continues.

basically, this shows that the difference between 3 and 12 is 9, the difference between 12 and 25 is 13 (which is 4 more than 9), the difference between 25 and 42 is 17 (which is 4 more than 12), and so on.

using this pattern, all we have to do is find the next difference- the one between 42 and the missing term.

to do this, we take the previous difference, 17, and add 4. this gives us 21.

have you seen or read about an example where data were presented on an issue, but the sample was not representative of the population from which it was drawn? if you can't recall a specific example, locate one using an internet search.

Answers

A specific example of a non-representative sample can be seen in the 2016 US presidential election.

The national polls indicated that Hilary Clinton had a lead in the polls, but Donald Trump went on to win the election. This is because the sample used in the polls was not representative of the population. The sample was disproportionately composed of college-educated individuals, when the actual electorate was more evenly balanced between college-educated and non-college-educated individuals. This caused the samples to be biased and not representative of the population.

For example, if we assume that the population is composed of 50% college-educated individuals and 50% non-college-educated individuals, then the sample should also be composed of 50% college-educated individuals and 50% non-college-educated individuals to be representative. If the sample is not composed of 50% college-educated individuals and 50% non-college-educated individuals, then the sample is not representative of the population.

This can be calculated by using the formula: (Number of College Educated Individuals in Sample/Total Sample Size) X 100.

For example, if the sample size is 100 and there are 75 college-educated individuals in the sample, then the sample is not representative of the population because (75/100) X 100 = 75%, which is not equal to the 50% of the population that is college-educated.

The smallest amount of rotation about the vertex from one ray to the other, measured in degrees.

Answers

The smallest amount of rotation about a vertex from one ray to the other can be calculated by subtracting the sum of the two ray measures from 180°.

The smallest amount of rotation about a vertex from one ray to the other can be calculated using the formula θ = 180° - (α + β), where θ is the measure of the angle of rotation, α and β are the measures of the two rays that are connected by the vertex. The amount of rotation between two rays is measured in degrees, which is equal to the angle between the two rays. The formula used to calculate the amount of rotation is the arctangent of the ratio of the difference in the y-coordinates to the difference in the x-coordinates. For example, if the two rays have measures of 90° and 30°, the smallest amount of rotation from one ray to the other would be 60°. This can be calculated by taking 180° - (90° + 30°) = 180° - 120° = 60°. In conclusion, the smallest amount of rotation about a vertex from one ray to the other can be calculated by subtracting the sum of the two ray measures from 180°.

The required total income generated by planting corn in 2008 is the amount of $1917.85.

What are the functions?

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The yield of corn on Mr. Geller's farm since 2001 can be modeled by the function N(t) = 10t + 88.5

Let's find the amount of corn produced in 2008:

N(7) = 10 x 7 + 88.5 = 158.5 (kilograms)

Next, let's find the price of corn in 2008:

P(7) = 81 - 10 x 7 + 1.1 = 12.1 ($/kilogram)

Finally, we can multiply the amount of corn by the price per kilogram to find the total income:

158.5 x 12.1 = 1917.85

Rounding to the nearest cent, the total income generated by planting corn in 2008 is $1917.85.

∠A = 20°

Let us consider in triangle side opposite to angle A, B, and C are a, b, and c respectively.

Using cosine rule we have,

a² = c² + b² - 2cbcos A

Substitute the values we get,

⇒ 12² = c² + 30² - 2(c )(30) cos 20°

⇒ 144 = c² + 900 - 60c ( 0.9396)

⇒ c² -56.376c + 900 - 144 = 0

⇒ c² -56.376c +756 = 0

using quadratic formula :

c = [ ( 56.376) ± √56.376² -4(1)(756) ]/ 2

  =  [ 56.376 ± 12.42 ] / 2

  =  (56.38 + 12.42) / 2 or (56.38 - 12.42) / 2

Another way to express cis 75∘+cis 83∘+cis 91∘+⋯+cis 147∘

Answers

the value of theta in the given complex expression is equal to 16°.

Given, a number. [tex]rcis\theta, is[/tex] expressed by.

cis75° + cis83° + cis91°+.... + cis147°.

we have to find the value of angle in degrees.

The function cisA is a shorthand way of writing the equivalent expression cisA=cosA+i sinA

By definition: CisA=CosA+iSinA

This form simplifies complex arithmetic and allows for the study of complex analysis, as well as reduces the workload in writing the expressions.

now, we have to find the sum of the given expressions.

[tex]cis75+cis83+cis91+...+cis147 as, cis\theta=e^{i\theta}[/tex]

[tex]e^{75i}+e^{83i}+e^{91}+....+e^{147i}\\\\e^{\frac{75\pi}{180} }+e^{\frac{83\pi}{180} }+.....+e^{\frac{147\pi}{180} }[/tex]

on using geometric sum of the series we get,

[tex]Sum=\frac{e^{\frac{75i\pi}{180}}(1-e^{\frac{72i\pi}{180} ) }}{(1-e^{\frac{8i\pi}{180} })}\\ \\\theta=16[/tex]

the value of theta of the angle be 16 degree.

The most appropriate time-series plot for a particular dataset will depend on the data being visualized. The title, axes labels, and scale should all be chosen carefully to accurately describe the data and provide the clearest understanding of the data. For example, for a time series of stock prices, the title could be "Stock Price Over Time", the axes could be labeled "Time" and "Price", and the scale could range from the lowest to the highest stock price. Additionally, the time intervals should be appropriately labeled, such as monthly, quarterly, or annually. It is important to choose the right type of plot to ensure that the data is accurately and clearly represented.
