Answer:
75%
Step-by-step explanation:
24/6=4
1/4=6
4*6=24
24-6=18
3/4 of 24=18
3/4=75%
The percentage decrease in length of the board is 25%
From the given statement we can deduce the following:
original length of the board = 24 cmnew length after cutting 6 cm = 24 cm - 6 cm = 18 cmThe change in the length of the board is calculated as:
Change in length = original length - new lengthChange in length = 24 cm - 18 cmChange in length = 6 cmThe percentage decrease in the length is calculated as;
[tex]Percentage \ decrease = \frac{change \ in \ length }{original \ length} \times 100\%\\\\Percentage \ decrease = \frac{6}{24} \times 100\%\\\\Percentage \ decrease = 25\%[/tex]
Thus, the percentage decrease in length of the board is 25%

Which is defined using the undefined terms point and line?
A) angle
B) circle
C) parallel lines
D) ray
Answer:
i would say circle cause there no evan lines angles or points in it
Step-by-step explanation:
The object which is defined using undefined terms of points and lines is option D)
D) Ray
Reason for electing the above option is as follows;
Undefined terms are terms that are not required to be given formal definition in them selves and they include the terms set, plane, line, and point
A point is a dimensionless marker of position and it is indicated in geometry by a capital letter. In geometry, a point is the most elementary entity
A line is an infinitely long and straight geometric object that is defined and named by any two points located on it
A ray is a subset of a line that extends long straight infinitely in one direction, and has a starting point
Therefore, the geometrical object defined by a point and a line is a ray and the correct option is option D)

Step-by-step explanation:
................
Parallel line geometry
==========================================================
Explanation:
See the diagram below. I've extended one of the rays to form a full line. This is shown in red. The alternate interior angles 60 and x are congruent due to the parallel lines, so x = 60.
We can then find angle y
x+y+20 = 180 ... angles of a triangle add to 180
60+y+20 = 180
y+80 = 180
y = 180-80
y = 100
Use this to find z
y+z = 180
100+z = 180
z = 180-100
z = 80
Or you could use the remote interior angle theorem
x+20 = z
60+20 = z
80 = z
z = 80

x + 5y +3z = 4
4y – z=3
6x – 2y + 4z = 0
Answer:
x = [tex]\frac{1}{4}[/tex]
y = [tex]\frac{3}{4}[/tex]
z = 0
Step-by-step explanation:
You first need to solve for a variable, it won't be as easy as x = 3, you are looking to replace a variable with another equation.
For example, the second equation, 4y-z=3, I can either solve for y or z. It won't be a numerical value but it will get you a step closer.
4y-z=3
4y=z+3
y = [tex]\frac{z}{4} +\frac{3}{4}[/tex]
Then you are able to use substitution to negate one of the variables and solve for the other two variables. I won't type that but I think you get the idea.

how to solve a variable?
Answer:
In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns.

two fourth-degree polynomials are multiplied together. what is the degree of the product?
Answer:
The product of a fourth degree polynomial and a third degree polynomial is a 7th degree polynomial (just add the two degrees). Why is this the case? Remember, when you multiply variables with common bases, you add the exponents. Since the degree of a polynomial is just the largest exponent, you're really just adding the degrees when you multiply
