Round to the nearest hundredth, if necessary. Complete the statement. 30.9mm = in
Answers
The complete statement is 30.9mm = 1. 21 in
What is conversion of units?Conversion of units is simply the conversion between different units of measurement for a particular quantity.
Given the statement;
30.9mm = in
It is important to note that;
25. 4 millimeters = 1 inch
Then;
30. 9 millimeters = x inches
Cross multiply
x × 25. 4 = 30. 9 × 1
To make 'x' the subject
Divide both sides by 25. 4, we have;
x = 30. 9/ 25. 4
x = 1. 21 Inches
Thus, the complete statement is 30.9mm = 1. 21 in

Applying the linear pair postulate:
y = 30
m<ACB = 160°
What is the Linear Pair Postulate?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:
y = 30
m<ACB = 160°

Answers
answer is y ≤ [tex]\frac{1}{3}x (-4)[/tex]
Given that,
Area of shaded inequality below solid line is positive
and y-intercept of the solid line is equal to - 4
therefore,
The inequality must be
y ≤ [tex]\frac{1}{3}x (-4)[/tex]
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.

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

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.

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

3x - 2x = 8 - 7 + 8
x = 16 - 7
x = 9
Now,
AC = 3x - 8 = 3 x 9 - 8 = 27 - 8 = 19

If you can fit 19 people in a 5ft x 5ft square, how many people would fit along a parade route, 10ft deep on each side of the street and one mile long?
Answers
There are 40128 peoples in the parade route by proportion.
According to the given question.
You can fit 19 people in a 5ft x 5ft square.
Here we need to find the number of peoples in the 10ft x 1 mile parade.
Since, we have to convert miles into feet then,
1 mile = 5280 feet
We know that the parade route is in the form of rectangle.
Also, the process of proportion reasoning involves understanding the multiplicative relationships between rational quantities.
Now we will find the number of peoples by proportions,
Let us consider the number of people in the rectangle as x.
Therefore,
19/25 = x/5280
⇒ (19/25)(5280) = x
⇒ x = 40128
Hence, there are 40128 peoples in the parade route by proportion.

Seamus sees a good helmet that is 195 and on a 35% off discount. What is the original price?
Answers
The original price of the helmet is 300.
What is percent?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.
