The Area of the figure ≈ 19 units²

Area of a semicircle = 1/2(πr²), where r is the radius.

Area of a triangle = 1/2(b)(h), where b is the base and h is the height of the triangle.

The figure can be decomposed into a semicircle and a triangle.

Area of the figure = 1/2(πr²) + 1/2(b)(h)

r = 1/2(7) = 3.5 units

π = 3.14

b = 7 units

h = 3 units

Substitute

Area of the figure = 1/2(3.14)(3.5²) + 1/2(7)(3)

Area of the figure ≈ 19 units²

The size of the actual book is 9 inches. The actual book is 18 inches long and is blank inside.

The inch is used as a unit of length in both the British imperial and American customary measurement systems. It is the same as one-twelfth of a foot or one-third of a yard.

The characteristics of an object or event are measured and quantified so that they can be contrasted with those of similar objects or occurrences. Therefore, measurement is the process of determining the size or smallness of a physical quantity in relation to a primary reference quantity of a similar kind.

(Option a) Gonzalez and Bros . Inc has the absolute advantage when it comes to producing phones.

Absolute advantage theory

Adam Smith, an economist from the 18th century, introduced the idea of absolute advantage in his book The Wealth of Nations to explain how nations might profit from trade by specializing in producing and exporting the things that they can manufacture more successfully than other nations.

On the other hand, low-cost manufactured items are produced and exported by China, Thailand, and Vietnam. These three nations enjoy a distinct advantage as a result of their significantly reduced unit labor costs.

The equation that represents the cost of jake's cell phone bill is -

y = 2x + 40 . Option - B is the correct alternative.

We have a graph representing jake's cell phone bill.

We have to write a equation that represents the cost of jake's cell phone bill.

The general equation of a straight line is given by -

y = mx + c

where -

m → slope of line.

c → y - intercept of line.

According to the question -

The y - intercept of the line is at the coordinates (0, 40). Now, we have to find the slope of this line. Consider the two coordinates -

A(0, 40) and B(10, 60)

Slope of a straight line is given by -

m = y₂ -y₁ / x₂ - x₁

m = 60 - 40 / 10 - 0

m = 20 / 10

m = 2

Now, substituting the values in the general equation of line, we get -

y = 2x + 40

Hence, Option B → y = 2x + 40 is the correct alternative.

Using proportions, it is found that the dedicated link would take 5.72 hours, which is significantly less time than the USPS delivery, hence the link should be used.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

Each TB has 1000 GB, hence:

20.6 terabytes = 20,600 Gigabytes.

You have available a 1 Gbps dedicated link for data transfer, hence the time it would take for the transfer through the dedicated link is:

The balance of current assets of the firm is 54 million dollars.

The total of all current assets is the current asset balance. These include cash, cash equivalents, pre-paid expenses, inventories, and any other assets that are anticipated to be turned into cash throughout the course of the following year.

Any debts owed by your business to others, including bank loans, mortgages, unpaid bills, IOUs, and other sums of money, are referred to as liabilities.

We know that to calculate the balance of current assets we use the formula.

Current assets=working capital +current liabilities

Working capital=net income÷(profit margin × sales to working capital)

Now given the working capital=$20 million

Profit margin=5%

Working capital=20÷(8×5%)

or, working capital = 50

Now current assets=Working capital+liabilities

Hence balance of current assets= 50+4 million dollars

The number of plans that cost between 41.46 and 63.42 is 504 to the nearest whole number

We have the following data to solve this problem with

n = 738 home owners

standard deviation sd = 10.98

The number of plans is between 41.46 and 63.42

Such that we will have

p(41.46 < x< 63.42)

Then we would have

P(41.46 - 52.44 / 10.98) < z< (63.42 - 52.44 / 10.98)

= P (-1 < z < 1)

We have p(z < 1) = 0.8413

therefore p(z > 1) = 1 - 0.8413

= 0.1587

0.8413 - 0.1587 = 0.6826

This is the same as 68.26%

68.26% x 738 = 503.76

Using Venn sets, it is found that 30 athletes own none of the items.

The missing information is the question, which asks how many athletes own none of the items.

For this problem, we consider the following sets:

10 owned all three items, hence:

(A ∩ B ∩ C) = 10.

57 owned a convertible and a TV, hence:

(A ∩ B) + (A ∩ B ∩ C) = 57.

(A ∩ B) = 47.

50 owned a TV and a store, hence:

(B ∩ C) + (A ∩ B ∩ C) = 50

(B ∩ C) = 40.

29 owned a convertible and a store, hence:

(A ∩ C) + (A ∩ B ∩ C) = 29.

(A ∩ C) = 19.

136 owned a sporting goods store, hence:

C + (A ∩ C) + (B ∩ C) + (A ∩ B ∩ C) = 136

C + 19 + 40 + 10 = 136

C = 67.

117 of them owned a giant screen TV, hence:

B + (A ∩ B) + (B ∩ C) + (A ∩ B ∩ C) = 117

B + 47 + 40 + 10 = 117

B = 20.

135 of them owned a convertible, hence:

A + (A ∩ B) + (A ∩ C) + (A ∩ B ∩ C) = 135

A + 47 + 19 + 10 = 135

A = 59.

There were 292 athletes on the survey, hence the number who owned none is given as follows:

None + A + B + C + (A ∩ B) + (A ∩ C) + (B ∩ C) + (A ∩ B ∩ C) = 292

None + 59 + 20 + 67 + 47 + 19 + 40 + 10 = 292

None + 262 = 292

None = 30.

The amount of property tax that was collected under old rates is $4,200,000 and new rates is $5,400,000.

(a) Take a look at the information provided.

$400,000,000 is the fair market value, and the assessment rate is 35%.

Thus, 35% = 35/100 = 0.35

Since fair market value x assessment rate equals assessment value

400,000,000 x 0.3 = 140,000,000

30-mill old property tax rate

To convert the tax rate from mills to decimal, multiply it by 0.001.

30x 0.001 = 0.03

Then, multiply the old tax rate by the previous assessment value of the property to determine the amount of property tax owed: 140,000,000 x 0.03 = 4,200,000.

Therefore, the amount of property tax that was collected at the previous rates was $4,200,000.

(b) The price at fair market is $400,000,000.

The evaluation rate is 45%.

45% = 45/100 = 0.45

As, or in other words,

assessment value = fair market value multiplied by the assessment rate.

As a result,

400000000 x 0.45 = 180000000

30 mills is the old property tax rate.

To compute the tax rate in decimal notation, multiply the millage rate by 0.001.

30 x 0.001 = 0.03

Calculate the property tax owing by multiplying the old tax rate by the previous assessment of the property: 180000000 x 0.03 = 5400000.

Therefore, the amount of property tax that was gathered at the new rates is 5,400,000.

Hence, the amount of property tax that was collected under old rates is $4,200,000 and new rates is $5,400,000.
