Answer:

To add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same. To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same.

There are many laws that govern the order in which you perform operations in arithmetic and in algebra. The three most widely discussed are the Commutative, Associative, and Distributive Laws.

The simplification of the given complex number is 4.70

Complex numbers are those numbers that contain the imaginary and the real part.

A Complex value z is written in a rectangular form as z = x+iy where (x, y) is the rectangular coordinates.

r is the modulus of the complex number and θ is the argument

r =√x²+y² and θ = tan⁻¹y/x

We need to simplify the complex number;

(30-50i)/(3-5i)

Therefore,

(30-50i)/(3-5i) x (3+5i)/(3+5i)

(30-50i) (3+5i)/(9 + 25)

90 + 150i - 150i - 250 /34

160/34

4.70

Answer:

To solve, you must isolate the variable. This means moving the variable and it's coefficient to the other side of the equation with only the same variable on the same side with all the constants on the other side.

If you multiply, divide, add, subtract, square root, exponent both sides of the equation by the same value, that end value stays the same.

Terminology

Variable: Any letter than stands for a value than can be solved and change value. (i.e. x, y, z, a, etc.)

Coefficient: The number right before a variable (without being separated by an operator). It is a multiplication factor for a variable. Basically, it's just a way to express what you are multiplying a variable by.

If the coefficient is 1, it means [variable] * 1. 1[variable]

Subtract 23 on both sides.

29 - 23 = v + 23 - 23

v = 29

Answer:

The appraiser said that the condo is currently worth $202,470 and it's 2% higher than the condo was worth when Mr. Duncan bought it several years ago. To find the value of the condo when he bought it, we need to subtract 2% of the current value from the current value.

We can find 2% of the current value by multiplying it by 0.02:

$202,470 x 0.02 = $4,049.4

To find the value of the condo when he bought it, we need to subtract $4,049.4 from the current value:

$202,470 - $4,049.4 = $198,420.6

Therefore, the value of the condo when Mr. Duncan bought it was $198,420.6

Answer:

The area of the composite figure can be calculated by breaking it down into separate geometric shapes and calculating the area of each shape. The figure can be divided into a rectangle and a triangle. The rectangle can be calculated by multiplying the length (16 feet) by the height (22 feet) resulting in 352 ft^2. The triangle can be calculated by multiplying the base (4 feet) by the height (8 feet) and dividing by 2, resulting in 16 ft^2. By adding the area of the rectangle and the triangle, we get 352 ft^2 + 16 ft^2 = 368 ft^2. So, the total area of the figure is 368 ft^2. Therefore, the correct answer is 440 ft2.

Step-by-step explanation:

above

If a five-sided figure with two parallel sides and the shorter one is 16 feet.  The figure that  represents the total area of the figure is: C. 440 ft2.

The rectangle is formed by the two parallel sides, which are 16 feet long.

The height= 22 feet.

The area of the rectangle =  16 feet x 22 feet

The area of the rectangle = 352 square feet.

The triangle is formed by the vertex, the perpendicular height, and the 4-foot side. The area of a triangle is (base x height) / 2.

Since the base of this triangle is 8 feet and the height is 22 feet.

The area of the triangle = (8 x 22) / 2

The area of the triangle= 88 square feet.

The total area of the composite figure is :

Total area = 352 square feet + 88 square feet

Total area  = 440 square feet

Therefore the correct option is C.

Answer: The expression which can be rewritten using a common factor is; xy/10 (x² + 2y).

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We have the following information given as;

One tenth times x cubed times y plus two tenths times x times y squared using a common factor.

We know that 'times' has to be replaced with multiplication.

Now, we will change this into mathematical expression as;

x³y/ 10 + 2xy²/ 10

Now, the common factor can be ;

xy/10

The Common factor refers to the number and the variables taken as a common factor should be able to completely divide the terms given any expression.

Now, taking it as a common factor, we have the following expression:

xy/10 (x² + 2y)

Hence, the required expression is; xy/10 (x² + 2y).

Step-by-step explanation:

The formula for the surface area of a cylinder is [tex]2\pi rh+2\pi r^{2}[/tex]. Using this, you can calculate that the cylinder's total surface area is 56[tex]\pi[/tex]. But, since Adrian only needs to find the surface area outside of the tire, I'm going to assume that you only need to apply [tex]2\pi rh[/tex] to your problem. Therefore, the answer is 24[tex]\pi[/tex] or 75.4 (rounded to the nearest tenth). I hope this helps!
