Step-by-step explanation:

the perimeter (the way one time around it) of a rectangle is

2×length + 2×width

length = 3×width

2×(3×width) + 2×width = 160

6×width + 2×width = 160

8×width = 160

width = 160/8 = 20 ft

length = 3×width = 3×20 = 60ft

Step-by-step explanation:

To compute the break-even sales (in barrels) for the current year, we need to first determine the contribution margin per barrel, which is the amount left over from the selling price of each barrel of beer after variable costs are subtracted.

Variable costs per barrel can be calculated as 75% of the cost of goods sold per barrel, which is:

Variable cost per barrel = (75% x Cost of goods sold) / Barrels sold

Variable cost per barrel = (0.75 x $1,628 million) / 37 million barrels

Variable cost per barrel = $33.00

Similarly, the variable marketing, general, and administration expenses per barrel can be calculated as:

Variable marketing, general, and administration expenses per barrel = (50% x Marketing, general, and administration expenses) / Barrels sold

Variable marketing, general, and administration expenses per barrel = (0.50 x $592 million) / 37 million barrels

Variable marketing, general, and administration expenses per barrel = $8.00

Therefore, the contribution margin per barrel is:

Contribution margin per barrel = Selling price per barrel - Variable costs per barrel

Contribution margin per barrel = $6,512 million / 37 million barrels - $33.00 - $8.00

Contribution margin per barrel = $98.00

To compute the break-even sales (in barrels) for the current year, we can use the following formula:

Break-even sales (in barrels) = Fixed costs / Contribution margin per barrel

Fixed costs can be calculated as:

Fixed costs = Income from operations + Variable marketing, general, and administration expenses x Barrels sold - Contribution margin per barrel x Barrels sold

Fixed costs = $4,292 million + $8.00 x 37 million barrels - $98.00 x 37 million barrels

Fixed costs = $1,108 million

Substituting this into the formula, we get:

Break-even sales (in barrels) = $1,108 million / $98.00 per barrel

Break-even sales (in barrels) = 11.29 million barrels

Rounding this to two decimal places and converting to millions, we get:

Break-even sales (in barrels) = 11.29 million barrels = 11.3 million barrels (rounded)

Answer:

percentage increase: 43,75%

Step-by-step explanation:

If we want to solve thai as an equation, we can write:

800 + (x/100) * 800 = 1150

we multiply: 800 + 800x/100 = 1150

we simplify: 800+ 8x = 1150

we bring the unknown to the left, and numbers to the right:

8x = 1150 - 800

8x = 350

we find x by dividing each part by 8

x= 43,75

(note that the x/100 in the first equation is the same thing as writing x%, so 800 plus a percentage of 800 is equal to 1150)

The zeros of the function are:

-¹/₂ ± √((3)/2) i, 1/3 and - 2

We want to find the Zeros of the polynomial:

f(x) = 3x⁴ + 8x³ + 6x² + 3x - 2

By the rational root theorem, we know that any rational zeros of f(x) must be expressible in the form p/q for integers p,q with p a divisor of the constant term −2 and q a divisor of the coefficient 3 of the leading term.

Therefore, the only possible rational zeros are:

±¹/₃, ±²/₃, ±1, ±2

Let's check x = 1/3 to get:

f(¹/₃) = 3(¹/₃)⁴ + 8(¹/₃)³ + 6(¹/₃)² + 3(¹/₃) - 2 = 0

f(-2) = 3(-2)⁴ + 8(-2)³ + 6(-2)² + 3(-2) - 2 = 0

Thus, x = 1/3 and - 2 are zeros of the function and (3x - 1) and (x + 2) are factors.

Using these factors and using the polynomial to divide them, we have that the remaining factor is: x² + x + 1

The zeros of x² + x + 1 are the Complex cube roots of 1, since

(x - 1)(x² + x + 1) = x³ - 1

using the quadratic formula, we have:

If a rectangle has a perimeter of 48 in. the length and width are scaled by a factor of 2.5, the perimeter of the resulting rectangle is 225 inches.

Let L be the length of the original rectangle and W be the width. Then, the perimeter of the original rectangle is P = 2L + 2W = 48 inches.

If we scale the length and width by a factor of 2.5, we get a new length of 2.5L and a new width of 2.5W. The perimeter of the new rectangle would be:

P' = 2(2.5L) + 2(2.5W)

= 5L + 5W

To find the new perimeter, we need to find the new values of L and W. Since the length and width are scaled by the same factor, we can write:

2.5L = kL

2.5W = kW

where k is the scaling factor.

Since the new rectangle is scaled by a factor of 2.5, k = 2.5. Therefore:

L' = 2.5L = 2.5(12) = 30 inches

W' = 2.5W = 2.5(6) = 15 inches

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by

[tex]\text{Z}=\dfrac{\text{X}-\mu}{\sigma}[/tex]

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X.

In this problem, we have that:

A study conducted in 2012 found the length of Atlantic cod caught in nets in Karlskrona to have a mean of 49.9 cm and a standard deviation of 3.74 cm, so [tex]\mu=49.9,\sigma=3.74[/tex].

What is the length in cm of the longest 15% of Atlantic cod in this area?

We have to find the value of X for the value of Z that has a p-value of 0.85.

Looking at the z-score table, we have that Z = 1.04 has a p-value of 0.8508. So, we have to find the value of X when .

So

[tex]\text{Z}=\dfrac{\text{X}-\mu}{\sigma}[/tex]

a.

i. 10% of $110,000 = $11,000 down payment

ii. Loan (mortgage) = $110,000 - $11,000 = $99,000

iii. Monthly payment = P * r * (1 + r)n / ((1 + r)n - 1), where P represents the principal amount, r represents the monthly interest rate, and n represents the number of monthly installments.

First, we must determine the quantity of monthly payments. Because it is a 30-year loan, the monthly installments are 30 * 12 = 360.

The monthly interest rate of 9% divided by 12 equals 0.0075.

When we plug in the values, we get:

$793.07 monthly payment

iv. Loan total interest paid = (monthly payment * number of instalments) - principal amount = ($793.07 * 360) - $99,000 = $184,465.20

b

i. Reduction in loan balance = $99,000 - $88,536 = $10,464

ii. To date, the total amount paid to the loan firm is (monthly payment * a number of payments) = ($793.07 * 120) = $95,168.40.

We multiplied by 120 (rather than 10*12) because we're computing total payments made so far, not the total payments made over the life of the loan.

iii. Total interest paid thus far = total money given to the loan business minus principal amount = $95,168.40 - $99,000 = -$3,831.60

The negative figure shows that the interest paid thus far has been less than the principal amount. This is because, in the early phases of the loan, the majority of the monthly payment goes towards interest, with only a little portion going toward principal reduction.

iv. Home equity  = value of the home - remaining debt

= $150,000 - $88,536

= $61,464

c.

i. New monthly payment = P * r * (1 + r)n / ((1 + r)n - 1), where P represents the remaining loan value, r represents the new monthly interest rate (6% / 12 = 0.005), and n represents the number of monthly payments remaining (360 - 120 = 240).

When we plug in the values, we get:

$63.63 is the new monthly payment.

Total interest paid on the new loan during the life of the loan = (new monthly payment * number of payments) - remaining loan balance = ($63.63 * 240) - $88,536 = $32,028.40

d.

Monthly savings = old monthly payment minus new monthly payment = $793.07 - $63.63= $729.44

Total interest paid on the new loan during the life of the loan = (new monthly payment * number of payments) - remaining loan balance = ($63.63 * 360) - $88,536 = $37,847.80

Because the new loan is being paid off over a longer period of time, the total interest paid during the life of the new loan is more than the remaining interest on the previous loan.

Using the distance formula, we know that the distance between points A and B is:

sqrt((3 - 0)^2 + (a - 4)^2) = 5

Simplifying:

sqrt(9 + (a - 4)^2) = 5

Squaring both sides:

9 + (a - 4)^2 = 25

Simplifying:

(a - 4)^2 = 16

Taking the square root of both sides (note that we can take the positive or negative square root since both will satisfy the equation):

a - 4 = ±4

Solving for a:

a - 4 = 4 or a - 4 = -4

a = 8 or a = 0

However, we need to check that these values of a actually make sense based on the given information. If a = 0, then the distance between A and B is:

sqrt((3 - 0)^2 + (0 - 4)^2) = sqrt(9 + 16) = 5

So a = 0 is a valid solution. If a = 8, then the distance between A and B is:

sqrt((3 - 0)^2 + (8 - 4)^2) = sqrt(9 + 16) = 5

So a = 8 is also a valid solution.

Therefore, the possible values of a are a = 0 or a = 8.

The value of a can be 0 or 8 if the distance between the given points is 5.

A straight line drawn between two points is the shortest distance between the two points. We can calculate the shortest distance by the distance formula.

Let A(0,4) = (x1,y1)

     B(3,a) = (x2,y2)

Using distance formula,

[tex]D = \sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]

As distance = 5 units

Therefore,

[tex]\sqrt{(x2-x1)^2 + (y2-y1)^2} = 5[/tex]

[tex]\sqrt{(3-0)^2 + ((a-4)^2} = 5[/tex]

[tex]\sqrt{(3)^2 + (a^2 + 16 + - 8a)} = 5[/tex]

Answer:

To determine the fluid replacement rate for a burn patient in the first 8 hours, we can use the Parkland formula:

Fluid (in liters) = 4 mL × body weight in kg × % total body surface area (TBSA) burned

First, we need to calculate the TBSA burned. We can use the Rule of Nines to estimate this:

Head: 9%

Left Arm: 9%

Right Arm: 9%

Upper Front Torso: 0%

Upper Back Torso: 0%

Lower Front Torso: 18%

Lower Back Torso: 18%

Upper Left Leg: 0%

Upper Right Leg: 0%

Lower Left Leg: 0%

Lower Right Leg: 9%

Total TBSA burned = 9 + 9 + 9 + 18 + 18 + 9 = 72%

Now we can plug in the values into the Parkland formula:

Fluid (in liters) = 4 mL × 50.9 kg × 72% = 14,694.72 mL

To convert mL to liters, we divide by 1000:

Fluid (in liters) = 14,694.72 mL ÷ 1000 = 14.69 L

This is the total amount of fluid the patient needs in the first 8 hours. To determine the hourly rate, we divide by 8:

Hourly fluid rate = 14.69 L ÷ 8 = 1.84 L/hour

Therefore, the patient should receive approximately 1.84 liters of fluid per hour in the first 8 hours of their care.
