Answer: To find the percent of waste, we need to first determine the fraction of waste.

For every 32 square feet used, 2 square feet are wasted. This can be expressed as:

2/32 = 1/16

So, the fraction of waste is 1/16.

To find the percentage, we need to multiply this fraction by 100:

1/16 * 100 = 6.25

Therefore, the percent of waste is 6.25%.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Here are the steps to calculate the percent waste of sheet steel:

Determine the amount of steel wasted per unit of steel used. The problem tells us that 2 sq ft of steel is wasted for every 32 sq ft used. Therefore, the waste-to-use ratio is 2/32.

Simplify the waste-to-use ratio, if necessary. In this case, the ratio can be simplified by dividing both the numerator and denominator by 2:

2/32 = 1/16

Convert the waste-to-use ratio to a percentage. To do this, we multiply the simplified ratio by 100:

1/16 * 100 = 6.25

Round the result, if necessary. The problem asks for a whole number or an exact decimal, so we round the result to one decimal place:

6.25 rounded to one decimal place is 6.3.

Therefore, the percent waste of sheet steel is 6.3%.

We would expect 306 people to go to see movies now, after the 32% decrease.

The expected value is calculated in statistics and probability analysis by multiplying each conceivable outcome by the likelihood that each outcome will occur, then adding up all of those values. By calculating anticipated values, investors can choose the scenario that is most likely to provide the desired outcome.

We must subtract 32% from the original number of persons in order to arrive at the anticipated number of people who would currently attend movies.

Let x represent the predicted proportion of moviegoers in the present. The following equation can be created:

x = 450 - 0.32*450

By condensing this equation, we obtain:

x = 450 - 144

x = 306

As a result, given the 32% decline, we would anticipate 306 individuals to attend movies this week.

To determine Kristina's federal taxes owed for 2022, we need to calculate her taxable income and apply the appropriate tax rate based on the tax brackets for single filers.

From her gross income of $32,500, we need to subtract the deductions that she can claim. Based on the information provided, Kristina can claim either the standard deduction of $12,550 or itemize her deductions, which in her case would be $6,320 + $19,500 = $25,820.

Since the itemized deductions are greater than the standard deduction, we will use the itemized deductions to calculate her taxable income.

Kristina's taxable income would be:

Gross income - Itemized deductions = $32,500 - $25,820 = $6,680

Next, we need to determine which tax bracket Kristina falls into. For tax year 2022, the tax brackets and rates for single filers are:

- 10% on income up to $10,275

- 12% on income between $10,275 and $41,775

- 22% on income between $41,775 and $91,525

- 24% on income between $91,525 and $191,525

- 32% on income between $191,525 and $416,700

- 35% on income between $416,700 and $418,850

- 37% on income over $418,850

Since Kristina's taxable income of $6,680 falls into the 10% tax bracket, her federal tax liability would be:

$6,680 x 0.10 = $668.00

Therefore, Kristina's federal taxes owed for 2022, using the deduction that is best for her, would be $668.00.

Answer:

Step-by-step explanation:

To calculate Kristina's federal taxes owed for 2022, we need to determine her taxable income first. To do this, we need to subtract her deductions from her gross income:

Gross Income = $32,500

Deductions = Mortgage Interest + Medical Expenses

Deductions = $6,320 + $19,500

Deductions = $25,820

Taxable Income = Gross Income - Deductions

Taxable Income = $32,500 - $25,820

Taxable Income = $6,680

Now, we can use the tax brackets and rates for single filers to determine Kristina's federal income tax liability for 2022. Based on the IRS tax tables for 2022, her tax liability would be calculated as follows:

The first $10,275 of taxable income is taxed at 10% = $1,027.50

The amount of taxable income over $10,275 but not over $41,775 is taxed at 12% = $601.20

Total Tax Liability = $1,027.50 + $601.20 = $1,628.70

Therefore, Kristina's federal taxes owed for 2022, using the deduction that is best for her, would be $1,628.70.

Answer:

Step-by-step explanation:

Let's use A to represent the number of adult tickets sold and C to represent the number of children tickets sold. We can set up two equations based on the information given:

The total number of tickets sold is the sum of adult and children tickets:

A + C = 487

The total proceeds from ticket sales is the product of the number of tickets and their respective prices:

47A + 29C = 17525

We can use the first equation to solve for one of the variables in terms of the other:

C = 487 - A

Substituting this expression for C into the second equation, we get:

47A + 29(487 - A) = 17525

Simplifying and solving for A:

18A + 14123 = 17525

18A = 3402

A = 189

So 189 adult tickets were sold. Using the equation C = 487 - A, we can find the number of children tickets sold:

C = 487 - 189 = 298

Therefore, 189 adult tickets and 298 children tickets were sold for the matinee.

Answer:

the amount of Basil Yamey's capital is £16,480.

Step-by-step explanation:

To calculate Basil Yamey's capital, we need to add up the value of his assets and subtract his liabilities.

The value of his assets is:

Van: £9,000

Market stall: £1,800

Computer: £280

Inventory of goods: £11,200

Cash in hand: £900

Money in the bank: £6,300

Total value of assets = £9,000 + £1,800 + £280 + £11,200 + £900 + £6,300 = £29,480

His liabilities are:

Amount still owed for inventory of goods: £5,000

Amount borrowed from Luca Pacioli: £8,000

Total liabilities = £5,000 + £8,000 = £13,000

Therefore, Basil Yamey's capital is:

Capital = Total value of assets - Total liabilities

Capital = £29,480 - £13,000 = £16,480

So the amount of Basil Yamey's capital is £16,480.

Answer:

Basil Yamey's capital is the total amount of money that he has invested in his business. This can be calculated as the sum of the cost of the assets that he has purchased, minus any outstanding debts, plus any cash or cash equivalents he has on hand.

The cost of the assets that Basil has purchased is:

£9,000 (van) + £1,800 (market stall) + £280 (computer) + £11,200 (inventory) = £21,280

He still owes £5,000 for the inventory, so the total cost of the assets minus the outstanding debt is:

£21,280 - £5,000 = £16,280

He borrowed £8,000, so the total amount of his capital is:

£16,280 + £8,000 = £24,280

He also has cash on hand and in the bank:

£900 (cash) + £6,300 (bank balance) = £7,200

So, Basil Yamey's total capital is £24,280 + £7,200 = £31,480.

Step-by-step explanation:

You want a volume of 1472 ft³ expressed in cubic meters.

One foot is exactly 0.3048 meters, so we can write the fraction ...

  (0.3048 m)/(1 ft)

and it will have a value of 1. When we multiply by this, it does not change the length, but it changes the units of the length.

The volume is expressed as the third power of the length unit, so we need to use this conversion factor 3 times.

  1472 ft³ = (1472 ft³) × ((0.3048 m)/(1 ft))³ = 1472·0.3048³ m³ ≈ 41.7 m³

What is an angle?

An angle is a figure in plane geometry that is created by two rays or lines that have a common endpoint. The Latin word "angulus," which means "corner," is the source of the English word "angle." The common endpoint of two rays is known as the vertex, and the two rays are referred to as the sides of an angle.

In the given figure, there are two pairs of vertically opposite angles.

The vertical opposite angle of 124⁰ is y⁰.

The vertical opposite angle of x⁰ is z⁰.

Thus, 124⁰ = y⁰ and x⁰ = z⁰.

The sum of all angles is 360⁰.

Therefore,

124⁰ + x⁰ +  y⁰ + z⁰ = 360⁰

Putting y⁰ = 124⁰ and x⁰ = z⁰ in the above equation:

124⁰ + z⁰ + 124⁰ + z⁰ = 360⁰

248⁰ + 2z⁰ = 360⁰

Subtract 248⁰ from both sides:

2z⁰ = 360⁰ - 248⁰

2z⁰ = 112⁰

Using Standard normal distribution, The probability that a family spends between $175 and $255 in playing video games every year is approximately 0.4821 or 48.21%.

Probability is a branch of mathematics that deals with the likelihood or chance of an event occurring. It is defined as the measure of the likelihood of an event happening, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. For example, the probability of rolling a 3 on a fair six-sided die is 1/6 because there is only one favorable outcome (rolling a 3) out of six possible outcomes (rolling a 1, 2, 3, 4, 5, or 6).

There are two types of probability: theoretical probability and experimental probability. Theoretical probability is based on mathematical analysis and assumes that all possible outcomes are equally likely to occur. Experimental probability, on the other hand, is based on actual observations and measurements of events and their outcomes.

Probability theory has many practical applications in fields such as statistics, economics, engineering, and physics. It can be used to model and predict the behavior of complex systems, such as stock prices, weather patterns, and the spread of diseases. Additionally, probability theory is used in decision-making processes to determine the most favorable course of action based on the likelihood of different outcomes.

(a) To find the probability that a family spends over $290 in playing video games every year, we need to standardize the value using the z-score formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

So, z = (290 - 238.92) / 31.38 = 1.63

Using a standard normal distribution table or a calculator, we can find that the probability of a z-score greater than 1.63 is 0.0516.

Therefore, the probability that a family spends over $290 in playing video games every year is approximately 0.0516 or 5.16%.

(b) To find the probability that a family spends less than $150 in playing video games every year, we again need to standardize the value using the z-score formula:

z = (x - μ) / σ

So, z = (150 - 238.92) / 31.38 = -2.83

Using a standard normal distribution table or a calculator, we can find that the probability of a z-score less than -2.83 is 0.0023.

Therefore, the probability that a family spends less than $150 in playing video games every year is approximately 0.0023 or 0.23%.

(c) To find the probability that a family spends between $175 and $255 in playing video games every year, we need to standardize the values of both $175 and $255 using the z-score formula:

z1 = (175 - 238.92) / 31.38 = -2.03

z2 = (255 - 238.92) / 31.38 = 0.51

Using a standard normal distribution table or a calculator, we can find the probability of a z-score between -2.03 and 0.51 is 0.4821.

Therefore, the probability that a family spends between $175 and $255 in playing video games every year is approximately 0.4821 or 48.21%.

Answer:

if 49.4 moles of MnO4- are available, 4300 g (or 4.3 kg) of MnO2 will be produced.

Step-by-step explanation:

16H+ (aq) + 2MnO4- (aq) + 10Br- (aq) → 2MnO2 (s) + 5Br2 (aq) + 8H2O (l)

From the balanced equation, we can see that 2 moles of MnO4- reacts with 2 moles of MnO2. Therefore, the number of moles of MnO2 formed is equal to the number of moles of MnO4- used.

First, let's calculate the number of moles of MnO4- used:

m(H2O) = 445 g

M(H2O) = 18.015 g/mol

n(H2O) = m/M = 445 g / 18.015 g/mol = 24.7 mol

Since 1 mol of H2O reacts with 2 moles of MnO4-, the number of moles of MnO4- required to react with 24.7 mol of H2O is:

n(MnO4-) = 2 × n(H2O) = 49.4 mol

Therefore, if we have 49.4 moles of MnO4- available, all of the MnO4- will be consumed and form the same number of moles of MnO2. The molar mass of MnO2 is 86.94 g/mol. The mass of MnO2 produced can be calculated as:

m(MnO2) = n(MnO2) × M(MnO2) = 49.4 mol × 86.94 g/mol = 4300 g

Therefore, if 49.4 moles of MnO4- are available, 4300 g (or 4.3 kg) of MnO2 will be produced.

m∠UTS = 87

m∠TSR = 143

Step-by-step explanation:

We know that the angles 56, (3 + 7x), and UST, add up to 180, and that UST and (12x - 1) also add up to 180

Therefore we can say UST = 180 - (12x - 1)

and that:

56 + 3 + 7x + (180 - (12x - 1)) = 180

59 + 7x + 180 - 12x + 1 = 180 (combine like terms and distribute negative)

240 - 5x = 180 (subtract 240 from both sides)

-5x = -60 (divide both sides by -5)

x = 12

m∠UTS = 3 + 7(12) = 87

We have,

f(x) = x + 1, for x ≤ 2

f(x) = 2x - 1, for 1 < x < 2

f(x) = x - 1, for x < 1

Now,

A x = 1

LHS of f(x) = lim f((h - 1)) =  (h - 1 - 1) = 0 -2 = -2

RHS of f(x) = lim  f(h + 1) =  (2(h + 1) - 1) = 2h + 2 - 1 = 0 + 1

f(1) = x + 1 = 1 + 1 = 2

f(x) = x - 1, for x < 1

Answer:

How many centimeters are there in 58 inches?

1 in. = 2.54 cm

Step-by-step explanation:

The domain and range of the given function :

Domain: {x | x ∈ ℝ, x ≠ -2}

Range: {y | y ∈ ℝ, y ≠ -12/5}

The given function is:

f(x) = (x^2 - 4x - 12)/(x + 2)

To find the domain of the function, we need to consider the values of x that make the denominator (x + 2) zero. If x + 2 = 0, then x = -2. Therefore, the function is undefined at x = -2, since division by zero is not allowed. Hence, the domain of the function is all real numbers except -2. We can express this mathematically as:

Domain: {x | x ∈ ℝ, x ≠ -2}

To find the range of the function, we need to consider the values that f(x) can take for all valid values of x. As x approaches infinity or negative infinity, the value of the function also approaches infinity (or negative infinity) since the degree of the numerator is greater than the degree of the denominator. Therefore, the range of the function is all real numbers except for a single point which is the vertical asymptote at x = -2.

Range: {y | y ∈ ℝ, y ≠ -12/5}

It is proved that  [tex]tan^2(x)*sin^2(x) = tan^2(x) - sin^2(x)[/tex]

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It has applications in fields such as engineering, physics, and navigation.

We can use the trigonometric identity:

[tex]tan^2(x) + 1 = sec^2(x)[/tex]

to derive the identity:

[tex]tan^2(x) = sec^2(x) - 1[/tex]

We can also use the identity:

[tex]sin^2(x) + cos^2(x) = 1[/tex]

to derive the identity:

[tex]cos^2(x) = 1 - sin^2(x)[/tex]

Then, substituting the second identity into the first, we get:

[tex]tan^2(x) = sec^2(x) - 1 = 1/cos^2(x) - 1 = (1 - cos^2(x))/cos^2(x) = sin^2(x)/cos^2(x) = tan^2(x)*sin^2(x)/(1 - tan^2(x))[/tex]

Multiplying both sides by [tex](1 - tan^2(x))[/tex], we get:

[tex]tan^2(x)*(1 - tan^2(x))*sin^2(x) = tan^2(x)*(1 - tan^2(x)) - sin^2(x)*tan^2(x)tan^2(x)*sin^2(x) - tan^4(x)*sin^2(x) = tan^2(x) - tan^4(x) - sin^2(x)*tan^2(x)tan^2(x)*sin^2(x) = tan^2(x) - sin^2(x)[/tex]

Hence Proved
