Brand A has a unit price of 8 cents per fork ($1.99 divided by 25), while Brand B has a unit price of 9 cents per fork ($3.89 divided by 42).

To determine which brand is the better buy based on the unit price, we compare the unit prices of each brand. In this case, Brand A has a lower unit price than Brand B, which means that it is the better buy. However, we should also consider the number of forks in each box. While Brand B has a higher unit price, it also has more forks per box than Brand A, which may be a more economical choice depending on the needs of the buyer.

The length of the rectangle : 81inches

What is Rectangle?

A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equal sides.

Given,

The perimeter of a rectangle = 110inches

The width of the rectangle = 14inches

Since,

we know that

Perimeter of Rectangle = 2 x (Length + width)

Putting the values

                                 110 = 2 x (L + 14)

                                  110 = 2L + 28

                               110 - 28 = 2L

                                82 = 2L

                                  L = 82/2

                                  L = 41

Hence,  The length of the rectangle is 81inches

To determine the number of airport x-ray scans a person would have to undergo before radiation sickness is detected at a level of 0.2 Sv (sieverts), we can calculate the ratio between the desired radiation dose and the dose per scan.

Given that a single x-ray scan has a biological radiation effect of 0.0009 mSv (millisieverts), we need to convert the desired radiation sickness threshold of 0.2 Sv into millisieverts. Since 1 Sv is equal to 1000 mSv, 0.2 Sv is equivalent to 200 mSv. Now, we can calculate the number of scans by dividing the desired dose by the dose per scan:

Number of scans = (Desired dose in mSv) / (Dose per scan in mSv)

Number of scans = 200 mSv / 0.0009 mSv ≈ 222,222 scans.

Rounded to the nearest whole number, a person would need to undergo approximately 222,222 x-ray scans before radiation sickness is detected at a level of 0.2 Sv. It is important to note that this is a theoretical calculation and that exposure to such a high number of scans is highly unlikely in practical scenarios.

The voltage across the capacitor at t=0+ is 4 volts (c \(V_c(t=0+)\) )is 4V). As time approaches infinity, the voltage across the capacitor becomes 6 volts ( \(V_c( t \to\infty)\) )is 6V). The current through the capacitor at t=0+ is -2 milliamperes ( \(i_c(t=0+)\) )is -2mA).

At t=0+, the switch opens and the circuit transitions into a new steady state. Initially, the capacitor is fully charged to 4V, so \(V_c(t=0+)\)is 4V. In the new steady state, the capacitor is connected to a series combination of R1, R2, R3, and R4. Since R1 and R2 are in series, their total resistance is 3kΩ. Thus, the time constant of the circuit is given by τ = (R1+R2+R3+R4)C = 6kΩ * 1μF = 6ms.

To determine\(V_c( t \to\infty)\) , we consider the steady state behavior of the circuit. In steady state, the capacitor acts as an open circuit. Therefore, the current flowing through R4 is zero, and the voltage drop across R4 is also zero. Thus, \(V_c( t \to\infty)\) is equal to the voltage drop across R3, which is 6V.

At t=0+, the current through R1, R2, and R3 will be the same as the current through the capacitor, ( \(i_c(t=0+)\) ). Applying Kirchhoff's current law at the node connecting R1, R2, R3, and the capacitor, we find that ( \(i_c(t=0+)\) )= I - (Vc(t=0+)/R1+R2+R3) = 4mA - (4V/3kΩ) = -2mA.

In summary, \(V_c(t=0+)\) is 4V, \(V_c( t \to\infty)\) is 6V, and \(i_c(t=0+)\)is -2mA.

The probability of selection of diagonal which is not shortest nor longest is 13/17.

We know very well that Icosagon has 20 sides.

If any diagonal is possible, it can be possible by connecting two points, so to choose r objects from n objects can be done by ⁿ \(C_{r}\) = \(\frac{n!}{r! (n-r)!}\)

So, number of ways to choose diagonal = \(^2^0C_{2}\)

After that we need to subtract 20 ways as single point can lead to diagonal making.

So, total number of ways to choose 20 diagonals =  170

Now, talking about the shorter diagonal

so, shorter diagonal =Diagonal connecting(A₁A₃, A₂A₄,.....) =20 diagonals.

Now, talking about longer diagonal=Diagonal connecting(A₁A₈,A₂A₉.........) = 20 diagonals

So, we have total chances of ⁿ \(C_{r}\) = \(\frac{n!}{r! (n-r)!}\) and possible number of chances of selection of shorter and longer diagonal

So, according to the formula,

Probability= Favorable outcome /Total outcome

Probability = [(Total ways to select diagonals - (Ways to select shorter diagonal) - Ways to select longer diagonal)]/(Total number of ways)

Probability = (170-20-20)/170

Probability = 130/170

Probability = 13/17

Hence, the probability of selecting a  diagonal such that it is not shortest nor longest is 13/17.

Rusty would recognize a capital gain of $187 due to the partial liquidation of Nail Corporation.

To determine the amount and character of the income or gain recognized by Rusty due to the partial liquidation, we need to compare the distribution received to Rusty's stock basis and the fair market value of the shares.

In this case, Nail Corporation distributed $555,440 to Rusty in exchange for 50% of his stock in the company. The fair market value of the shares at the time of the distribution was $212 per share, and Rusty's tax basis in the shares was $50 per share.

First, we calculate the total tax basis in the shares Rusty exchanged:

Tax basis = Number of shares exchanged * Tax basis per share

Tax basis = 50% * Tax basis per share

Tax basis = 50% * $50 = $25

Next, we calculate the gain on the exchange by subtracting the tax basis from the fair market value of the shares:

Gain on exchange = Fair market value of shares - Tax basis

Gain on exchange = $212 - $25 = $187

Since the distribution was made in exchange for Rusty's stock, the gain of $187 recognized by Rusty in the partial liquidation is treated as a capital gain.

Therefore, Rusty would recognize a capital gain of $187 due to the partial liquidation of Nail Corporation.

Answer:

x=20,y=34

Step-by-step explanation:

x+14=2x-6 (vertically opposite angles)

x-2x = -6-14

-x = -20

x=20

x+14=y (corresponding angles)

20+14=y

y=34

Answer:

x = 20, y = 34

Step-by-step explanation:

(2x - 6) and (x + 14) are vertical angles and are congruent, then

2x - 6 = x + 14 ( subtract x from both sides )

x - 6 = 14 ( add 6 to both sides )

x = 20

Then

2x - 6 = 2(20) - 6 = 40 - 6 = 34

y and (2x - 6) are alternate angles and are congruent , so

y = 34

Angle 1 is 147 degrees

Step-by-step explanation:

When two angles form a linear pair, then we have the intersection of two lines

So what this mean is that both angles lie on a straight line and the sum of both angles is 180.

Let the angle 2 be x

We are told that angle 1 is 18 degrees less than 5 times the measure of angle 2;

What we are saying here is that; angle 1 = 5x - 18

So let’s add both together to give 180

angle 1 + angle 2 = 180

x + 5x -18 = 180

6x = 180+ 18

6x = 198

x = 198/6

x = 33 degrees

But angle 1 is 5x -18 = 5(33) -18 = 165 -18 = 147 degrees

The present value of Selena's legacy, which she will receive in 20 years, can be calculated using the formula for continuous compounding. Assuming an interest rate of 5.1% compounded continuously, we can determine the amount of money needed today to yield $300,000 in 20 years.

The formula for continuous compounding is given by the equation:

PV = FV / e^(rt)

Where PV is the present value, FV is the future value, r is the interest rate, t is the time period in years, and e is the mathematical constant approximately equal to 2.71828.

In this case, FV is $300,000, r is 5.1% (or 0.051), and t is 20 years. Plugging in these values into the formula:

PV = 300,000 / e^(0.051 * 20)

To find the present value, we need to calculate e^(0.051 * 20). Evaluating this expression:

e^(0.051 * 20) ≈ 2.71828^(1.02) ≈ 2.77302

Now, we can calculate the present value:

PV = 300,000 / 2.77302 ≈ $108,170.63

Therefore, the present value of Selena's legacy, considering continuous compounding at an interest rate of 5.1%, is approximately $108,170.63.

The expression 1/tan(x) + tan(x) is equal to cos(x) + sin(x). Therefore, option B. Sin(x)cos(x) is correct.

To simplify the expression 1/tan(x) + tan(x), we need to find a common denominator for the two terms.

Since tan(x) is equivalent to sin(x)/cos(x), we can rewrite the expression as:

1/tan(x) + tan(x) = 1/(sin(x)/cos(x)) + sin(x)/cos(x)

To simplify further, we can multiply the first term by cos(x)/cos(x) and the second term by sin(x)/sin(x):

1/(sin(x)/cos(x)) + sin(x)/cos(x) = cos(x)/sin(x) + sin(x)/cos(x)

Now, to find a common denominator, we multiply the first term by sin(x)/sin(x) and the second term by cos(x)/cos(x):

(cos(x)/sin(x))(sin(x)/sin(x)) + (sin(x)/cos(x))(cos(x)/cos(x)) = cos(x)sin(x)/sin(x) + sin(x)cos(x)/cos(x)

Simplifying the expression further, we get:

cos(x)sin(x)/sin(x) + sin(x)cos(x)/cos(x) = cos(x) + sin(x)

Therefore, the expression 1/tan(x) + tan(x) is equal to cos(x) + sin(x).
