The number of times that the Great Wall of China is as long as the Panama Canal will be 2 × 10².

It should be noted that the Great Wall of China built in the 7th century BCE, is about 1 x 10⁴ miles long and the Panama Canal, built two thousand years later, is about 5 x 10^1 miles long.

Therefore, the number of times that the Great Wall of China is as long as the Panama Canal will be:

= 1 × 10⁴ / 5 × 10¹

= 2 × 10²

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Given expression is 3(a-b)(3r-T)+9(b-a)(2t-5s) the factorization will be done as below:-

E = 3(a-b)(3r-T)+9(b-a)(2t-5s)

E =  3(a-b)(3r-T)- 9(a-b)(2t-5s)

E = 3(a-b){[3r-T]-392t-5s]}.

The original price of the helmet is 300.

In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now it is given that,

Price of helmet = 195

Discount on helmet = 35% = 0.35

Let the original price be x.

Now since Price of helmet = 195

Thus, Original price = x - 0.35x = 0.65x

Hence we get

0.65x = 195

Dividing both the side by 0.65 we get

x = 195/0.65

Solving we get

x = 300

this is the required original price of the helmet.

Thus, the original price of the helmet is 300.

Answer: 1b. 5x - 30, 1c. -8x - 32, -8x + 12, 1e. -6x + 21, 1f. 3( 3x - 9)

Step-by-step explanation:

You multiply the number outside of the parentheses by the numbers inside, if it's just an "x", you assume there's a 1 beside it, ex: 8(x + 2)... 8 multiplied by x will give you 8x, 8 multiplied by 2 will give you 16.

if the numbers are both negative when you multiply them it becomes a positive, ex: -8(x - 2)... -8 multiplied by x will be -8, and -8 multiplied by -2 will become positive 16.

But if one number is negative and the other is positive then the answer will be negative.

The expression equivalent to [tex]\frac{12x^{4} }{4x^{16} }[/tex] is 3[tex]x^{-12}[/tex] or 3[tex]x^{4-16}[/tex].that is option C) is correct.

According to the question the expression that we have been given to us is :

               [tex]\frac{12x^{4} }{4x^{16} }[/tex]

Note that we know the property of exponent which states that if teh exponents with same base and different power are divided then the powers are subtracted. That is,  

                 [tex]\frac{x^{m} }{x^{n} } = x^{m-n}[/tex]          (1)

Now using this rule we will evaluate the equation given that is

             = [tex]\frac{12}{4} * \frac{x^{4} }{x^{16} } \\\\[/tex]

First we will divide 12/4 which gives 3 then we will apply the property of exponent to the exponent function which gives,

             = 3 [tex]x^{4-16}[/tex]

             = 3 [tex]x^{-12}[/tex]

Hence the expression equivalent to [tex]\frac{12x^{4} }{4x^{16} }[/tex]  is 3[tex]x^{-12}[/tex]or 3[tex]x^{4-16}[/tex] that is option C) is correct.

The length of AC and AB is 19 and 11.

It is the measurement of something from end to end or along its longest side or a measurement of a particular part of something:

We have,

BC = 8

AC = 3x - 8

AB = 2x - 7

We can  make the line as:

A______B______C

We can write as:

AC = AB + BC

3x - 8 = 2x - 7 + 8

Simplify all the like terms together.

3x - 2x = 8 - 7 + 8

x = 16 - 7

The simplified form of (2 + i)/(2 - i) is (3 + 4i)/5

A Simple Form or simplified form can be defined as When a fraction's numerator and denominator share only one common factor, it is said to be in its simplest form.

Consider the given complex number(2 + i)/(2 - i)

Multiply both numerator and denominator with the complex number (2 + i), and we get

{(2 + i) × (2 + i)} / {(2 + i) × (2 - i)}= {(2 + i) × (2 + i)} / (2² - i²)          

(using the formula (x + y)(x - y) = x² - y²)= {(2 + i) × (2 + i)} / (4 - (-1))= {(2 + i) × (2 + i)} / (4 + 1)= {(2 + i) × (2 + i)} / 5= (2² + 2i + 2i + i²)/5= (4 + 4i + (-1))/5= (3 + 4i)/5

Applying the linear pair postulate:

y = 30

m<ACB = 160°

According to the linear pair postulate, the sum of two adjacent angles that form a linear pair is equal to 180 degrees.

Given the following:

m<ACB = (4y + 40)°

m<DCE = (y - 10)°

Angles ACB and DCE are a linear pair. Therefore:

m<ACB + m<DCE = 180°

Substitute

(4y + 40) + (y - 10) = 180

Solve for y

4y + 40 + y - 10 = 180

Combine like terms

5y + 30 = 180

Subtract 30 from both sides

5y + 30 - 30 = 180 - 30

5y = 150

Divide both sides by 5

5y/5 = 150/5

y = 30

Find m<ACB:

m<ACB = (4y + 40)°

Plug in the value of y

m<ACB = 4(30) + 40

m<ACB = 120 + 40

m<ACB = 160°

Thus, applying the linear pair postulate:

In Mathematics, inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths. In this case, the equal sign “=” in the expression is replaced by any of the inequality symbols such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤) or not equal to symbol (≠). The different types of inequalities in Maths are polynomial inequality, rational inequality, absolute value inequality.

A system of linear inequalities in two variables includes at least two linear inequalities in the identical variables. When we solve linear inequality then we get an ordered pair. So basically, in a system, the solution to all inequalities and the graph of the linear inequality is the graph displaying all solutions of the system. Let us see an example to understand it.

the Linear inequality: 2x – y >1, x – 2y < – 1

The symbols ‘<‘ and ‘>’ express the strict inequalities and the symbols ‘≤’ and ‘≥’ denote slack inequalities. A linear inequality seems exactly like a linear equation but there is a change in the symbol that relates two expressions.

here is given step to easily find the value of inequality:

Step 1: The inequality is already in the form that we want. That is, the variable y y is isolated on the left side of the inequality.

Step 2: Change inequality to equality. Therefore, y > x + 1y>x+1 becomes y = x + 1y=x+1.

Step 3: Now graph the y = x + 1y=x+1. Use the method that you prefer when graphing a line. In addition, since the original inequality is strictly greater than symbol, \Large{>}>, we will graph the boundary line as a dotted line.

Step 4: The original inequality is y > x + 1y>x+1. The greater than symbol implies that we are going to shade the top area or region.
