can y'all help me solve b and c please​

Answer:

Triangle inequality rule states that the sum of eachpair of sides must be greater than the third sides.

240 + 123 > 207 true

240 + 207 > 123 true

123 + 207 > 240 true

A = √(s(s-a)(s-b)(s-c))

s is the semi-perimeter (a + b + c)/2

s = (240 + 123 + 207)/2

s = 285

A = √(285*(285-249)(285-123)(285-207))

A = 12,730 units^2

The net profit for the year ending December 31, 2021, is £1,000. Therefore, the correct answer is d) £1,000.

To determine the net profit for the year ending December 31, 2021, we need to calculate the total revenue and subtract the total expenses. Let's analyze the transactions provided:

The owners invested £550,000 of their own funds into the business bank account. This does not affect the net profit as it represents an owner's contribution of capital.

The business used £16,000 from the bank account to purchase short features and fashion. This expense reduces the net profit.

The business used £10,000 from the bank account to buy new inventory. This expense also reduces the net profit.

The business bought additional inventory worth £9,000 on credit. This is not an expense for the current year as it represents an increase in assets.

The shop sold £28,000 worth of inventory to customers for cash. This revenue increases the net profit.

The business sold goods costing £6,000 to another business on credit for £8,000. This revenue also increases the net profit.

The business paid £9,000 in rent from the bank account. This expense reduces the net profit.

Depreciation and estimated electricity expenses are not mentioned in the given transactions and cannot be calculated.

The owners withdrew £10,000 in cash for personal use. This is not an expense for the business and does not affect the net profit.

Based on the provided information, we can calculate the net profit as follows:

Total Revenue = £28,000 (from sales to customers) + £8,000 (from sales to another business) = £36,000

Total Expenses = £16,000 (short features and fashion) + £10,000 (new inventory) + £9,000 (rent) = £35,000

Net Profit = Total Revenue - Total Expenses = £36,000 - £35,000 = £1,000

Therefore, the net profit obtained is £1,000.

Answer:

The amount Trevor's family pay per minute on shower water is $0.005.

Step-by-step explanation:

The cost of water is,

Cost = $0.20/liter

Amount of water used over the entire month:

Amount of water used = 72 liters

Compute the total water cost as follows:

Total water cost = Amount of water used × Cost

                           = 72 × 0.20

                           = $14.4/liter

The average number of minutes each person showered is:

Average number of minutes = 480 minutes.

The number of people in Trevor's house:

N = 6

Compute the total amount of time the 6 person showered as follows:

Total amount of time = Average number of minutes × N

                                   = 480 × 6

                                   = 2880 minutes

Compute the pay per minute on shower water as follows:

Pay per minute on water = Total water cost ÷ Total amount of time

                                          = $14.4 ÷ 2880

                                          = $0.005

Thus, the amount Trevor's family pay per minute on shower water is $0.005.

Explanation:

There are 3 right triangles here. They are all similar triangles allowing us to form the proportion

7/h = h/56

which solves to...

7/h = h/56

7*56 = h*h

392 = h^2

h^2 = 392

h = sqrt(392)

h = sqrt(196*2)

h = sqrt(196)*sqrt(2)

h = 14*sqrt(2)

Note: h is the geometric mean of 7 and 56.

---------------------

Use the pythagorean theorem to solve for 'a'. Focus on the smaller triangle on the left

7^2 + h^2 = a^2

7^2 + (sqrt(392))^2 = a^2

49 + 392 = a^2

441 = a^2

a^2 = 441

a = sqrt(441)

a = 21

---------------------

Then we can find b. Again use the pythagorean theorem. Focus on the largest right triangle this time.

a^2 + b^2 = (7+56)^2

21^2 + b^2 = 63^2

441 + b^2 = 3969

b^2 = 3969 - 441

b^2 = 3528

b = sqrt(3528)

b = sqrt(1764*2)

b = sqrt(1764)*sqrt(2)

b = 42*sqrt(2)

The ratio of the plant cell's length to its width is 2:1 (5.8 x 10^-6 m to 2.9 x 10^-6 m).

To calculate the ratio of the plant cell's length to its width, we first need to find the length and width of the cell. The given data states that the length of the cell is 5.8 x 10^-6 m and the width is 2.9 x 10^-6 m. To calculate the ratio, we divide the length by the width. In this example, we divide 5.8 x 10^-6 m by 2.9 x 10^-6 m, which equals 2. Thus, the ratio of the plant cell's length to its width is 2:1.

length / width = 5.8 x 10^-6 m / 2.9 x 10^-6 m = 2

length : width = 5.8 x 10^-6 m : 2.9 x 10^-6 m = 2:1

To find the equivalent expression of -6n+(-12)+4n, we can start by combining like terms:

-6n + (-12) + 4n = (-6n + 4n) + (-12) = -2n + (-12) = -2n - 12

So, the equivalent expression of -6n+(-12)+4n is -2n - 12.

Therefore, the equivalent expression of -6n+(-12)+4n−6n+(−12)+4n is (-2n - 12) - (-2n - 12) = 0.

Profit = I(x) - E(x).Evaluating this expression using the optimal value of x will give us the maximum profit for the job.

To find the optimum number of days for the job, we need to determine when the income rate, I'(x), equals the expenditure rate, E'(x). Setting them equal to each other, we have:

98.8 - 0.5x = e'

Solving for x, we find that x = (98.8 - e') / 0.5. This gives us the optimum number of days for the job.

To calculate the total income for the optimum number of days, we substitute this value of x into the income function, I(x). So the total income, I(x), will be:

I(x) = ∫(98.8 - 0.5r) dr from 0 to x

Integrating and evaluating the integral, we obtain the total income.

To find the total expenditures for the optimum number of days, we substitute the same value of x into the expenditure function, E(x). So the total expenditures, E(x), will be:

E(x) = ∫(e') dr from 0 to x

Again, integrating and evaluating the integral will give us the total expenditures.

Answer:  P=20s+14

Step-by-step explanation:

   The perimeter is P=2(W+L)=2[(9s+6)+(s+1)]

   So, P=2[10s+7]=20s+14

   P=20s+14

The perimeter of the rectangle is calculated by using the equation 2× (Length + Width). In this case, the width of the rectangle is (9s+6) cm, and the length is (s+1) cm. Thus, the expression for the perimeter is 2×(10s + 7) cm.

The perimeter of a rectangle is calculated by adding together the lengths of all four sides. Given that the width of the rectangle is (9s+6) centimeters, and the length is (s+1) centimeters, we can write the formula for the perimeter (P) as:

P = 2×(Length + Width)

Substituting values:

P = 2×((s+1) + (9s+6))

Simplify the equation to:

P = 2×(10s + 7)

So, the expression for the perimeter of this rectangle is 2×(10s + 7) centimeters.

For the construction of reinforced concrete water storage tanks that will hold water with high salinity and a high concentration of sulfates, I recommend using sulfate-resistant cement with appropriate admixtures. This combination will help ensure the durability and high-quality performance of the concrete.

Given the high salinity and sulfate concentration in the water, it is crucial to select a concrete mix that can withstand these aggressive conditions. I would recommend using sulfate-resistant cement, such as Type V cement, which is specifically designed to resist the deteriorating effects of sulfates. Type V cement contains a lower percentage of tricalcium aluminate (C3A), which is highly reactive with sulfates, resulting in reduced sulfate attack.

To further enhance the concrete's durability and resistance to sulfates, appropriate admixtures should be used. One important admixture is a high-range water reducer, commonly known as a superplasticizer. This admixture improves the workability of the concrete mix while reducing the water content, leading to increased strength and reduced permeability. Additionally, air-entraining agents should be included to create a system of microscopic air bubbles within the concrete, which provides resistance to freeze-thaw cycles and improves durability.

It is essential to maintain an appropriate water-to-cement ratio to ensure the concrete's strength and durability. A low water-to-cement ratio should be maintained to minimize permeability and enhance the concrete's resistance to sulfate attack. Adequate curing is also crucial to achieve the desired strength and durability. Curing methods like moist curing or using curing compounds should be employed to prevent moisture loss and promote proper hydration of the cement.

In summary, for the construction of reinforced concrete water storage tanks exposed to high salinity and a high concentration of sulfates, the use of sulfate-resistant cement, such as Type V cement, along with suitable admixtures like superplasticizers and air-entraining agents, is recommended. Proper water-to-cement ratio and curing methods should also be carefully implemented to produce durable, high-quality concrete that can withstand the aggressive conditions and ensure the longevity of the water storage tanks.
