how many hours and still elapsed from 0740 hrs to 1135 hrs.?

Answer:

Area = 6x² - 20x + 16

Step-by-step explanation:

The area of a rectangle is length x width.

Plug the values into that equation:

\(A = (2x-4)(3x-4)\)

Now you use the FOIL method to find the answer:

First: 2x × 3x = 6x²

Outer: 2x × (-4) = - 8x

Inner: (-4) × 3x = - 12x

Last: (-4) × (-4) = 16

Area = 6x² + (-8x) + (-12x) + 16

Area = 6x² - 20x + 16

Answer:26 eggs

Step-by-step explanation: yes

The market woman bought 60 eggs.

The market woman bought n eggs at the rate of 12 eggs for €60.

So, the cost price of each egg is given by:

Cost price per egg = €60 / 12 = €5

The total cost of n eggs is the cost price per egg multiplied by the number of eggs (n):

Total cost = €5 * n = 5n

After buying n eggs, 8 of them were broken.

So, the market woman had (n - 8) eggs left to sell.

She sold the remaining eggs at the rate of 4 eggs for €24.

The selling price of each egg is given by:

Selling price per egg = €24 / 4 = €6

The total selling price of the remaining (n - 8) eggs is the selling price per egg multiplied by the number of remaining eggs (n - 8):

Total selling price = €6 * (n - 8) = 6n - 48

The profit is the difference between the total selling price and the total cost:

Profit = Total selling price - Total cost

Since the problem states that the market woman made a profit of €12, we can set up the equation:

6n - 48 - 5n = 12

Solve for n.

Combine like terms:

n - 48 = 12

Add 48 to both sides:

n = 60

So, the market woman bought 60 eggs.

The surface area of the given cylinder is 602.88 square centimeters.

The surface area of the cylinder is: A = 2πr(r+h)

where 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

The cylinder with a height of 10 cm and a radius of 6 cm.

⇒ A = 2πr(r+h)

Here h = 10 cm and r = 6 cm

Substitute the known values in the above formula,

⇒ A = 2(3.14)(6)(6+10)

⇒ A = (12.56)(6)(16)

The estimated median price of a single-family home in Charleston/No. Charleston in the 1st Quarter of 2008 is $201,048. If the median price continues to decrease at the same rate for the next two years, the estimated median price of a single-family home in the 1st Quarter of 2011 would be $144,458.

(a) To estimate the median price of a single-family home in the 1st Quarter of 2008, we need to calculate the original price before the 8.15% decrease. Let's assume the original price was P. The price after the decrease can be calculated as P - 8.15% of P, which translates to P - (0.0815 * P) = P(1 - 0.0815). Given that the end of 1st Quarter of 2009 median price was $184,990, we can set up the equation as $184,990 = P(1 - 0.0815) and solve for P. This gives us P ≈ $201,048 as the estimated median price of a single-family home in the 1st Quarter of 2008.

(b) If the median price of a single-family home falls at the same rate for the next two years, we can calculate the price for the 1st Quarter of 2011 using the estimated median price from the 1st Quarter of 2009. Starting with the median price of $184,990, we need to apply an 8.15% decrease for two consecutive years. After the first year, the price would be $184,990 - (0.0815 * $184,990) = $169,805.95. Applying the same percentage decrease for the second year, the price would be $169,805.95 - (0.0815 * $169,805.95) = $156,012.32. Therefore, the estimated median price of a single-family home in the 1st Quarter of 2011 would be approximately $144,458.

Answer:

Mr. A initially paid approximately N8000 for the land.

Step-by-step explanation:

Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.

Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.

Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.

Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240

Step 5: Simplifying the equation: 1.155x - x = N1240

Step 6: Solving for x: 0.155x = N1240

x = N1240 / 0.155

x ≈ N8000

Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.

In general, to evaluate the function f(x) at a specific value of x, we substitute that value into the expression for f(x) and simplify.

In mathematics, a function is a relation between two sets, where for every element in the first set (called the domain), there is exactly one element in the second set (called the range) that the function maps to. In simpler terms, a function is a rule that assigns each input value from the domain to exactly one output value in the range. Functions are usually represented by a formula or equation that describes the relationship between the input and output values. For example, the function f(x) = 2x + 1 maps every input value of x to an output value that is twice the input value plus 1.

Here,

To evaluate the function f(x) = 4x - 6, we substitute the given values of the independent variable into the expression for f(x) and simplify.

For example:

f(0) = 4(0) - 6 = -6

f(1) = 4(1) - 6 = -2

f(2) = 4(2) - 6 = 2

f(-1) = 4(-1) - 6 = -10

f(3a) = 4(3a) - 6 = 12a - 6

Answer:

The system is inconsistent or incomplete, and we cannot determine a solution for both a and b.

Step-by-step explanation:

Let's solve each system of linear equations one by one.

(a) x - 2y + 32 = 7

   2x + y + z = 4

  -3x + 2y - 2 = -10

To solve this system, we can use the method of elimination or substitution. Here, let's use the method of elimination:

Multiplying the first equation by 2, we get:

2x - 4y + 64 = 14

Adding the modified first equation to the second equation:

2x - 4y + 64 + 2x + y + z = 14 + 4

Simplifying, we have:

4x - 3y + z = 18   --> Equation (1)

Adding the modified first equation to the third equation:

2x - 4y + 64 - 3x + 2y - 2 = 14 - 10

Simplifying, we have:

-x - 2y + 62 = 4   --> Equation (2)

Now, we have two equations:

4x - 3y + z = 18   --> Equation (1)

-x - 2y + 62 = 4   --> Equation (2)

We can continue to solve these equations simultaneously. However, it seems there was an error in the input of the equations provided. The third equation in the system (a) appears to be inconsistent with the first two equations. Therefore, the system is inconsistent and has no solution.

(b) 3r - 2y + 2z = 7

   1 - 3y + 22 = 2

   2x - 3y + 4z = 6 - 10

Simplifying the second equation:

-3y + 22 = -1

Rearranging, we have:

-3y = -1 - 22

-3y = -23

Dividing both sides by -3:

y = 23/3

Substituting this value of y into the first equation:

3r - 2(23/3) + 2z = 7

Simplifying, we get:

3r - (46/3) + 2z = 7   --> Equation (3)

Substituting the value of y into the third equation:

2x - 3(23/3) + 4z = -4

Simplifying, we get:

2x - 23 + 4z = -4

2x + 4z = 19   --> Equation (4)

Now, we have two equations:

3r - (46/3) + 2z = 7   --> Equation (3)

2x + 4z = 19            --> Equation (4)

We can continue to solve these equations simultaneously or further manipulate them. However, there seems to be an error in the input of the equations provided. The second equation in the system (b) is not complete and doesn't form a valid equation. Therefore, the system is inconsistent or incomplete, and we cannot determine a solution.

If v=<8,3,5> w=<2,2,2>, the cosine of the angle between vectors v and w is approximately 0.93294.

To find the cosine of the angle between vectors v and w, we will use the formula:
cos(θ) = (v • w) / (||v|| ||w||)
where θ is the angle between the vectors, v • w is the dot product of v and w, and ||v|| and ||w|| are the magnitudes of v and w, respectively.
First, let's find the dot product (v • w):
v • w = (8 * 2) + (3 * 2) + (5 * 2) = 16 + 6 + 10 = 32
Next, let's find the magnitudes of v and w:
||v|| = √(\(8^2 + 3^2 + 5^2\)) = √(64 + 9 + 25) = √98
||w|| = √(\(2^2 + 2^2 + 2^2\)) = √(4 + 4 + 4) = √12
Now, let's find the cosine of the angle between v and w:
cos(θ) = (32) / (√98 * √12) = 32 / (9.899494936611665 * 3.4641016151377544) ≈ 0.93294

where Ф is the angle between v and w, the . represents the dot product, and || || represents the magnitude or length. First, let's calculate the dot product of v and w:

v.w = 8*2 + 3*2 + 5*2 = 32

Next, let's calculate the magnitudes of v and w:

||v|| = sqrt(8^2 + 3^2 + 5^2) = sqrt(98)

||w|| = sqrt(2^2 + 2^2 + 2^2) = sqrt(12)

Now we can substitute these values into the formula:

cos(Ф) = (v.w) / (||v|| ||w||)
cos(Ф) = 32 / (sqrt(98) * sqrt(12))
