A 2.8 metre long ribbon costs rupees 4.90. how much would a 1 metre ribbon cost

Product B has recorded a greater percentage change in price over the previous year.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
For product A,
F(x) = 72(1.25)ˣ
The percentage is given  = [1.25 - 1] × 100% =  25%,

For product B,
From the table percentage change can be evaluated as,
= 84.5 - 65 / 65 × 100%
= 30%

Thus, Product B has recorded a greater percentage change in price over the previous year.

If the  dividend of  $1.50 is expected in two months. The European put price is $3.03.

Given:

K=50, r=0.1, σ=0.3, and T=0.25

First step is to find the stock price

S0 = 50−1.50e^ -0.1667×0.1

SO=48.52

Second step is to find di and d2

d1=In(48.52/50)+(0.1+0.09/2)0.25/0.3√0.25

d1 = 0.0414

d2=d1-0.3√0.25

d2 = -0.1086

Third step is to calculate European put price

European put price=-50N(0.1086)e^ -0.1×0.25−48.52N(−0.0414)

European put price=50×0.5432e -^0.1×0.25−48.52×0.4835

European put price=$3.03

Therefore If the  dividend of  $1.50 is expected in two months. The European put price is $3.03.

True. The double integral can be used to compute the area of a region d in a plane by integrating the function f(x,y). In fact, the double integral of f(x,y) over a region D in the xy-plane gives the volume of the solid between the surface z=f(x,y) and the xy-plane over the region D.

However, if we take the function f(x,y) to be the constant function 1, then the double integral of f(x,y) over the region D is simply the area of the region D. Therefore, we can compute the area of a region D in a plane by integrating the constant function 1 over the region D using the double integral. Integrating over two variables requires calculating two separate integrals, so the answer is more than 100 words.
True. A double integral can be used to compute the area of a region D in a plane by integrating the function f(x, y). To find the area, you would integrate the function f(x, y) = 1 over the region D, as the double integral represents the sum of the function values over the entire area. The double integral can be thought of as a generalization of single-variable integration, allowing us to find the area in two dimensions.

The body mass index of a person 65 inches tall with a weight of 175 pounds is 29.12

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

The body mass index (BMI) is given by:

BMI = [mass in pounds / (height in inches)²] * 703

Given mass = 175 pounds, height = 65 in, hence:

BMI = [175/65²] * 703 = 29.12

BMI = 29.12

The ratio of the volume of sphere B to the volume of sphere A is 125, since the volume of a sphere is proportional to the cube of its radius. Therefore, when the radius of sphere B is five times the radius of sphere A, the volume of sphere B is 5 cubed, or 125 times, the volume of sphere A.

The volume of a sphere is proportional to the cube of its radius. This means that if the radius of one sphere is increased by a certain factor, the volume of that sphere is increased by that same factor cubed. Therefore, if the radius of sphere B is five times the radius of sphere A, then the volume of sphere B is 5 cubed, or 125 times, the volume of sphere A. This means that the ratio of the volume of sphere B to the volume of sphere A is 125. The calculation for this is relatively simple. The formula for the volume of a sphere is 4/3π\(r^3\), where r is the radius of the sphere. In this case, the radius of sphere A is expressed as r, and the radius of sphere B is expressed as 5r. Therefore, the volume of sphere A is (4/3π)\(r^3,\) and the volume of sphere B is (4/3π)\((5r)^3\). The ratio of the two volumes is (4/3π)\((5r)^3\)/(4/3π)\(r^3\), which simplifies to 125. Therefore, the ratio of the volume of sphere B to the volume of sphere A is 125

The area of the SAS triangle is 460.89 cm³.

Given data;

Side length (a) = 29

Side length (b) = 36

With an angle of Ф = 62°

Here, it is stated that the triangle is a SAS triangle which is known as the Side Angle Side triangle.

Now, to calculate the area of a given triangle, we use the formula as;

Area = a*b*sinФ/2

From the above formula;

Area of the SAS triangle = a*b*sinФ/2

                                         = [29*36*sin(62°)]/2

                                         = 460.89 cm³

The store owner's profit is 25% of the selling price of grapes, which corresponds to option B.

The store owner buys the grapes for 80 cents and sells it for 100 cents, so the profit is 100-80 = 20 cents.

The percentage of the profit is (profit/cost) x 100%. In this case, the profit is 20 cents and the cost is 80 cents, so the percentage of profit is (20/80) x 100% = 25%.

Therefore, the store owner's profit is 25% of the selling price of grapes, which corresponds to option B.

To factorize the algebraic expression 3x² + 6x + 4x + 8, you can follow these three steps:

Step 1: Grouping

Group the terms in pairs so that you can factor out a common factor from each pair.

3x² + 6x + 4x + 8

(3x² + 6x) + (4x + 8)

Step 2: Factoring out the common factors

Factor out the common factors from each pair separately.

3x(x + 2) + 4(x + 2)

Step 3: Factoring out the common factor from the resulting expression

Notice that we have a common factor, (x + 2), in both terms.

(x + 2)(3x + 4)

Therefore, the factored form of the expression 3x² + 6x + 4x + 8 is (x + 2)(3x + 4).

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.

A student's probability of having a sister are 1/2 or 0.5 if they do not have a brother.

Using the above data table, we must determine the likelihood that a student without a brother also has a sister. Analysing the table now

has a sibling: 5

possesses no sisters: 2

has an 18-year-old brother

possesses no brothers: 4

We are looking for the likelihood that a student has a sister and neither a brother (as indicated by the statement "Does not have a brother"). In this instance, there are two children who do not have a brother but do have a sister, making that number the number of positive outcomes.

No matter whether a student has a sister or not, the total number of outcomes is equal to the number of students who do not have a brother. According to the table, there are 4 students without brothers.

As a result, the likelihood that a student who doesn't have a brother will have a sister can be determined as follows:

Probability is calculated as the ratio of the number of favourable outcomes to all possible outcomes.

The quadratic function is defined as follows:

The quadratic function has the following sets of values below:

(0,8) (2,10) (3,1).

The quadratic function is represented as follows:

f(x) = ax² + bx + c

using  (0,8)

8 = a(0)² + b(0) + c

8 = c

Therefore, using (2, 10)(3 , 1).

f(x) = ax² + bx + c

10 = a(2)² + b(2) + 8

10 - 8 = 4a + 2b

2 = 4a + 2b

1 = 2a + b

1 = a(3)² + b(3) + 8

1 = 9a + 3b

Hence, combine the equations,

2a + b = 1

9a + 3b = 1

multiply equation(i) by 3

6a + 3b = 3

9a + 3b = 1

3a = - 2

a = - 2 / 3
