Mathematics is a computational system developed by the Babylonians.

Mathematics has its roots in ancient civilizations, such as the Babylonians and Egyptians, who used mathematical concepts for practical purposes such as measuring land, calculating taxes and predicting astronomical events. The ancient Greeks made major contributions to mathematics with the development of geometry by Euclid and the formulation of mathematical proofs by Pythagoras and his followers.

The 17th and 18th centuries saw a major development in calculus by mathematicians like Isaac Newton and Gottfried Wilhelm Leibniz, which revolutionized the field and opened up new avenues of scientific investigation. In the 19th and 20th centuries, mathematicians such as Georg Cantor, Kurt Gödel, and Alan Turing made major contributions to the foundations of mathematics and the development of computer science.

The second largest of the four angles is angle ∠1

Triangle is a closed polygon that is formed by connecting 3 line segments which are called sides of the triangle. In a triangle, the shortest side will always be placed opposite the smallest interior angle. Similarly, the longest side will always be opposite the largest interior angle.

Here we have

The side included by <1 and <2 is 11 cm

The side included by ∠2 and ∠3 is 16 cm  

The side included by ∠3 and <1 is 14 cm  

As we can observe angle ∠4 is an obtuse angle

Hence, ∠4 is the largest angle among the 4 angles

As we know the shortest side is placed opposite the smallest interior angle and the longest side is opposite the largest interior angle.

From the given data,

The side included by ∠2 and ∠3 is the longest side

Hence, the largest angles among ∠1, ∠2, and ∠3 are the angles ∠1

Therefore,

Answer: A

Step-by-step explanation:

If there is a $5000 Unearned Revenue credit on the accounting worksheet, it means that the company has received payment for products or services that have not yet been delivered. Therefore, when the delivery is made, an adjusting entry is needed to reflect the change in the company's financial statements.

The adjusting entry would be a debit to the Unearned Revenue account for $5000 and a credit to the Revenue account for $5000, reflecting the delivery of the products and the recognition of revenue. The entry would be recorded in the Adjustment column of the worksheet.

Therefore, the correct answer is option A, a $5000 Adjustment debit.

Answer:

A. a $5000 Adjustment debit

Step-by-step explanation:

The delivery of products listed as a $5000 Unearned Revenue credit would be recorded on an accounting worksheet with a $5000 Adjustment debit.

Unearned revenue is a liability account that represents payments received from customers for goods or services that have not yet been provided. When the delivery is made and the products are provided, the unearned revenue is "earned" and the revenue is recognized in the accounting records.

To record the delivery and recognize the revenue earned, the company would make an adjusting entry to decrease the unearned revenue account and increase the revenue account. Since the unearned revenue account has a credit balance, the adjusting entry would require a debit to reduce the balance. This would result in a $5000 Adjustment debit to Unearned Revenue and a $5000 Adjustment credit to Revenue.

Answer:

There are many expressions equivalent to this.

Step-by-step explanation:

Let's solve the equation.

In the parentheses, you cannot do ×+, so I will assume that × is meant to be a variable, x.

You can use distributive property to solve this.

3(2x + 5)

3 × 2x + 6x

3 × 5 = 15

6x + 15 cannot be done.

So, the answer to the equation is 6x + 15.

An Equivalent Expression

An equivalent expression can be 2(3x + 7.5)

Let's solve it.

2 × 3x = 6x

2 + 7.5 = 15

So, the answer to this equation is 6x + 15.

6x + 15 = 6x + 15.

2(3x + 7.5) = 3(2x + 5)

Answer:

40 ft²

Step-by-step explanation:

First way:

A = 1/2bh = 1/2(16)(5) = 40

2nd way:

Length of dotted line at top = x

16² - 8² = x²

x² = 192

x = √192 = 13.86

Area rectangle = 8 x 13.86 = 110.85

Find the shaded area:

110.85 - 1/2(8)(13.86) - 1/2(8)(13.86 - 10) = 40

Answer:

  40 ft²

Step-by-step explanation:

You want the area of a triangle two different ways. The height from the 10 ft base is given as 8 ft; the height from the 16 ft base is given as 5 ft.

The area formula for a triangle is ...

  A = 1/2bh . . . . . . where b is the base, and h is the height from that base

The base (side) dimensioned in red is 10 ft. The perpendicular distance to the opposite vertex is shown in red as 8 ft. Then the area is ...

  A = 1/2(10 ft)(8 ft) = 40 ft²

The base dimensioned in green is 16 ft. The perpendicular distance to the opposite vertex is shown in green as 5 ft. Then the area is ...

  A = 1/2(16 ft)(5 ft) = 40 ft²

The area of the triangle is 40 ft².

Answer:

I think the answer is B. Sorry if I'm wrong I really tried :(

Step-by-step explanation:

Answer: Let x be the number of days it takes for y workers to weed the field. Then, we know that x and y are inversely proportional, meaning that x * y = k, where k is a constant.

Since it takes 6 days for 10 workers to weed the field, we have:

6 * 10 = k

So, k = 60.

Now, to find the number of days it would take if there were 12 workers, we can plug in y = 12 and solve for x:

x * 12 = 60

x = 60/12

x = 5

Therefore, it would take 5 days for 12 workers to weed the field.

The contents of r0 will be 0x20000851, which is the first byte of the word stored at address 0x20000850.

The TI TM4C123 is a little-endian processor, meaning that it stores data in the memory in reverse order. This means that the first byte of a word will be stored at the lower address, and the last byte at the higher address.

In this example, register r1 contains the address 0x20000850. When we execute the ldr r0, [r1] instruction, the processor will read the value stored in memory at address 0x20000850 and store it in register r0.

Since this is a little-endian processor, the value stored in memory at address 0x20000850 will be the last byte of the word, and the value stored in memory at address 0x20000851 will be the first byte of the word.

This means that the contents of r0 will be 0x20000851, which is the first byte of the word stored at address 0x20000850.

The most precise classification of BCDE is a square.

Quadrilaterals are four sided polygons which also have four vertices and four angles.

Sum of all the interior angles of a quadrilateral is 360 degrees.

We have to find the length of adjacent sides of the quadrilateral BCDE.

If they are equal, then the quadrilateral is either square or rhombus.

If they are not equal, then they are either rectangle or parallelogram.

B(-1, -1), C(6, -2), D(5, -9), and E(-2, -8)

BC = [tex]\sqrt{(6--1)^2+(-2--1)^2}[/tex] = √50

CD = [tex]\sqrt{(5-6)^2+(-9--2)^2}[/tex] = √50

Adjacent sides are equal. So it is either square or rhombus.

If it is rhombus, length of diagonals BD and CE are not equal.

If it is square, length of diagonals BD and CE are equal.

BD = [tex]\sqrt{(5--1)^2+(-9--1)^2}[/tex] = √100 = 10

CE = [tex]\sqrt{(-2-6)^2+(-8--2)^2}[/tex] = √100 = 10

Length of diagonals are same. So it is a square.

Hence the given quadrilateral is a square.

Hence, the cylinder's content determines the apparent volume of the glassware, and also the difference between the cylinder as well as spherical volumes determines the glass's true capacity.

Capacity can be defined as the amount which can be held by any kind of vessel. This can depend upon their depth as well as their size.

Actual capacity is the volume of liquid that a glass vessel can contain while it is only partially filled, as opposed to capacity, which refers to the volume of liquid when the glass vessel is fully filled to the brim.

The distinction between both apparent capacity versus Actual capacity in parameters of surface area, as well as volume, is that the former refers to the entire surface area proportional volume of the vessel, whilst the latter refers to the surface area but instead the volume of the liquid that could also fit.

In this case if the coordinates of B are (x, y), we can write the equation:

(-2, 4) = ( (x + 5)/2, (7 + y)/2)

We can solve these two equations to find the coordinates of point B, we will get:

(x + 5)/2 = -2

x + 5 = -4

x = -4 - 5 = -9

The table shows the amounts of each day is attached below.

An equation is an expression that shows the relationship between two or more numbers and variables.

The total amount of snow that falls in three days equals the sum of the amount of snow that falls each day, then

s1 + s2 + s3 = Ts

Here s1 is the snow that fell on day 1, s2 on day 2, s3 on day 3 and Ts is the total amount of snow that fell over the three days.

We need to calculate the amount of snow that fell on the first two days by multiplying the total snow by the given fractions, like this:

s1 = 1/6 * 2 = 1/3

s2 = 7/12*2 = 7/6

Of the given four estimators, the one that shows the most bias is Mean = 20, SE = 1. Hence, Mean = 20, SE = 1 is the accurate choice.

The estimator with the highest value (Mean = 20) compared to the population parameter (15) is the most biased. The lower the standard error (SE = 1), the more confident the estimate, but if the estimate is far from the population parameter, it is considered biased.

In this case, the Mean = 20 estimator is the most biased because it has the greatest difference from the population parameter and the lowest standard error, indicating a high level of confidence in the estimate despite it being significantly different from the actual population parameter.
