R500 is available for Savings.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Zekele earns = R 6500

His bills in one month are:

Rent R1 650,

For positive acute angles A and B, it is known that sin A= 4/5 and tan B= 45/28 . Find the value of IIT A+B in simplest form. Question. user avatar image ...

the solution of sin(A + B) in simplest form is 27/35.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, We use the trigonometric identity as;

sin(A + B) = sin A cos B + cos A sin B

Hence, we need to find cos A and cos B.

Here, We know that;

⇒ sin A = 4/5,

By use the Pythagorean identity;

sin²A + cos² A = 1

sin² A + cos² A = 1

(4/5)² + cos² A = 1

16/25 + cos² A = 1

cos² A = 9/25

cos A = 3/5

And, we can use the identity;

tan B = sin B / cos B

to find sin B:

tan B = sin B / cos B

45/28 = sin B / √(1 - sin² B)

(45/28)² = sin² B / (1 - sin² B)

sin² B + (45/28)² sin² B = (45/28)²

sin² B (1 + (45/28)²) = (45/28)²

⇒ sin B = 3/7

Now that we have sin A, cos A, sin B, and cos B,

We can put them into the formula for sin(A + B):

sin(A + B) = sin A cos B + cos A sin B

sin(A + B) = (4/5)(45/28) + (3/5)(3/7)

sin(A + B) = 27/35

Therefore, the solution of sin(A + B) in simplest form is 27/35.

Although certain functions have discontinuities, it is feasible to redefine the function so that it becomes continuous at that point.

A continuous function in mathematics is a function without discontinuities, or any sudden changes in value. If we can guarantee arbitrarily small changes in the input of a function by limiting small enough changes, then the function is continuous.

We only need to change the function's value at this point to make f(x) continuous at x=0. To satisfy the concept of continuous functions and resolve the example issue, make the necessary adjustment to make the one-sided limits equal. We therefore set f(0)=4 f(0) = 4

The deadweight loss caused by a subsidy is the amount of economic welfare that is lost because of the subsidy. In this example, the deadweight loss caused by the subsidy is $800. Therefore, correct option will be D.$800.

This occurs because the subsidy distorts the market by creating a price below the market equilibrium. This results in an inefficient distribution of resources as some consumers are willing to pay a higher price than the subsidized price.

Additionally, it creates an excess demand for the good, resulting in an over-allocation of resources. In this case, the deadweight loss is the difference between the market price and the subsidized price, which is $800. The deadweight loss is a negative externality of subsidies, as it reduces the overall efficiency of the market.

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

The equation of circle is,

⇒ (x + 4)² +(y + 5)² = 64

Now, We know that;

The standard form of circle with center (h, k) and radius r is,

⇒ (x - h)² + (y - k)² = r²

Here, The equation of circle is,

⇒ (x + 4)² +(y + 5)² = 64

⇒ (x - (- 4))² + (y -  (-5))² = 8²

So, By comparing, we get;

The center of circle (h, k) = (- 4, - 5)

And, Radius of circle (r) = 8

Is the measure of the space occupied by a body bounded by an environment called perimeter, the same is expressed in units of squared side. Example: ft^2, m^2

The formula and procedure to solve this geometry exercise is:

A(rectangle) = length * width

Information about the problem:

A(stone) = 246 ft^2

A(fountain) = ?

Width = ?

Calculating the area of the fountain we get:

Area of fountain = area of the rectangle - 246

Area of fountain = (12 x 22) - 246

Area of fountain = 264 - 246

Area of fountain = 18 ft^2

Calculating the width of the fountain we have:

A(rectangle) = length * width

18 = W x 6

W = 18/6

W = 3 feet

Calculating the fraction of the area of the courtyard will be occupied by the fountain we get:

If angle A and angle B have the same measurement then m∠A = m∠B and ∠A ≅ ∠B. So, the correct option is B: II and IV only.

What is an angle?

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

It is given that ∠A and ∠B have the same measurement.

This represents that ∠A and ∠B must be equal and congruent also.

This can be written in expression form as -

∠A ≅ ∠B

For example if ∠A = 90° then ∠B = 90°.

This can be written in expression form as -

m∠A = m∠B

The measure of angle A is equal to measure of angle B.
