Answer:
Around o is the center point
The center point 0 is usually on a graph and you should use x axis if it doesn't say what axis o is. X + y are both 0 usually.
When you have 0 as a central point you are actually moving the shape at equality around just like you would with a pertractor.
So We have a same shape shown and you can do this by rotating the shape 180 so it looks upside down to how its shown originally or previously.
You then maneuver it around to the opposite graph diagonally opposite is most likely to be 180 degree.
So if it starts in x axis right side it will be in y axis diagonally to the left
You just have to show vertices or edges meet symmetrically from the 0 point like a mirror but also facing opposite direction as it has been rotated.
Step-by-step explanation:
The description of rotation of image of 180 degree around O is discussed below.
What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
Around o is the center point.
If it doesn't specify what the axis o is, use the x axis as the graph's centre point (0). Typically, (x+ y) are both 0.
The form at equality is actually moved around when 0 serves as the Centre, much like you would with a pertractor.
You can achieve this by turning the identical shape 180 degrees such that it appears upside down relative to how it was originally or previously displayed.
Hence, if it starts on the right side of the x axis, it will be on the left side of the y axis.
Thus, show how vertices or edges come together symmetrically from the origin, mirror-like, but also facing the other way because of rotation.

Write 4.768 as a common fraction, proper or improper and then reduce. .
The number n = 4.768 as a fraction is A = 596/125
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the number be represented as n
Now , let the fraction be A
where the value of n = 4.768
And , to convert a decimal to a fraction, we can write the decimal as a fraction with the decimal value in the numerator and a power of 10 in the denominator that corresponds to the number of decimal places.
For 4.768, the decimal value is 768, which is three decimal places to the right of the decimal point. Therefore, we can write:
4.768 = 4 + 0.768
= 4 + 768/1000
= 4000/1000 + 768/1000
= 4768/1000
This fraction can be reduced by dividing both the numerator and denominator by their greatest common factor, which is 8:
4768/1000 = (8 × 596)/(8 × 125)
A = 596/125
Hence , the fraction is A = 596/125

Complete the steps to find the area of the trapezoid.
Area of rectangle = square units
Area of triangle 1 = square units
Area of triangle 2 = square units
Area of triangle 3 = square units
Area of trapezoid = square units
Answer:
Area of rectangle: 256
Area of triangle 1: 24
Area of triangle 2: 16
Area of triangle 3: 96
Area of trapezoid: 120
Step-by-step explanation:
I just did the question on the thing so Ik I'm right.
-The graph measures by twos. To get the area of the rectangle get the base times height of it. That would be 16x16=256.
-Get base (8) times height (6) of triangle 1 then divide by 2, remember to count the squares by 2 for finding all areas. The formula would be 1/2(b)(h) because dividing by 2 is the same as multiplying times 1/2. Plug it in and (8)(6)=48 then divide by 2 which equals 24.
-Same formula for triangle 2. Plug it in and (8)(4)=32 and divide by 2 and it equals 16.
-Same formula for triangle 3. Plugged in is (12)(16)=192 divide by 2 and it equals 96.
-To find the area of the trapezoid get your rectangle area (256) and subtract all the triangle areas. So 256 - 6 - 16 - 96 = 120.
The area of the given shapes are required.
256 square units
24 square units

Find the value of X.
Answer:
x=110 i think
Step-by-step explanation:
x+20+2x-70+x+x+20+x+90
=6x+60
6x+60=720
6x=(720-60)
6x=660
660/6=110
x=110
hope this helps!
Answer:
Step-by-step explanation:
sum of all angles of polygon = (n-2)*180 {n is no of sides}
= (6-2)*180 = 4*180 = 720
90 + 2x-70 + x+20 +x + x+20 + x = 720
Bring like terms together
90 - 70 + 20 + 20 + 2x + x + x + x + x =720
60 + 6x = 720
6x = 720 - 60
6x = 660
x = 660/6
x = 110

Andre says 10x + 6 and 5x + 11 are equivalent because they both equal 16 when x is 1. Do you agree with Andre?
Answer:
No, They are not equivalent
Step-by-step explanation:
The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.
The variable in this question is x.
To prove this, we equate both expressions:
[tex]10x + 6 = 5x + 11[/tex]
[tex]10x - 5x = 11 - 6\\\\\\5x = 5\\\\\\x = 1[/tex]
This shows that they have the same value ONLY when x is 1.
This is why Andre says that they are equivalent, but they are not.
No, I do not agree with Andre because the two equations 10x + 6 and 5x + 11 are indeed equivalent.
Explanation:No, I do not agree with Andre. Two equations are considered equivalent if they have the same solution for all values of x.
Let's check if 10x + 6 and 5x + 11 are equivalent by substituting x = 1 into both equations:
For 10x + 6: 10(1) + 6 = 10 + 6 = 16
For 5x + 11: 5(1) + 11 = 5 + 11 = 16
We can see that both equations indeed equal 16 when x is 1, so Andre is correct in this case. 10x + 6 and 5x + 11 are equivalent equations.

A jar contains three red marbles and five green marbles. A marble is drawn at random and not replaced. A second marble is then drawn from the jar. Find the probability that the first marble is red and the second marble is green.
Answer:
P(red then green) = 5/8 * 3/7 = 15/56
Step-by-step explanation: Since this is a logical "and" case, we have to multiply the separate events' probabilities...thus P(red then green) = 5/8 * 3/7 = 15/56
Answer:
3/28
Step-by-step explanation:
3 red+ 5 green = 8 marbles in the jar
1st marble:
P(red) = number of red/ total = 3/8
We keep the marble
2 red+ 5 green = 7 marbles in the jar
P(green) = number of green/ total = 2/7
P (red,keep,green) = P(red)* P(green) = 3/8*2/7 = 6/56 = 3/28

A rectangle has a perimeter of 80 inches. Write an equation to represent the area A in terms of width w.
Do I use the perimeter?
Answer:
[tex]A = 40w-w^2[/tex]
Step-by-step explanation:
We are given the following in the question:
Perimeter of rectangle = 80 inches.
Let l be the length and w be the width of rectangle.
Perimeter of rectangle =
[tex]P= 2(l+w)[/tex]
Putting values, we get,
[tex]80 = 2(l+w)\\40 = l+w\\\Rightarrow l = 40 - w[/tex]
Now, we have to find the area of the rectangle in terms of w.
Area of rectangle =
[tex]A = l\times w[/tex]
Putting values, we get
[tex]A = (40-w)w\\A = 40w-w^2[/tex]
is the required expression of area of rectangle in terms of w.
Yes, the perimeter is used to calculate the length of the rectangle in the term of w.

In ΔMNO NM = 3 cm, NO = 4 cm and MO = 5 cm. List the angles in order from smallest to largest.
By identifying triangle MNO as a right-angled triangle with MO as the hypotenuse, the angles are listed from smallest to largest based on their opposite sides: angle M (smallest), angle O (middle), and angle N (largest at 90 degrees).
The student has asked to list the angles of triangle right -angled MNO in order from smallest to largest, given that NM = 3 cm, NO = 4 cm, and MO = 5 cm. This is a case of a right-angled triangle where the sides satisfy the Pythagorean theorem, with MO being the hypotenuse. The angles of a triangle are inversely proportional to their opposite sides. Therefore, the angle opposite the longest side (MO) is the smallest, and the angle opposite the shortest side (NM) is the largest.
Steps to determine angle size:
Use the Pythagorean theorem to confirm the right angle.
Identify the smallest and largest sides to determine the smallest and largest angles.
Apply the fact that the sum of angles in a triangle is 180 degrees to find the middle angle.
Since 3² + 4² = 5², triangle MNO is a right-angled triangle with the right angle at angle N.
The smallest angle is thus at M, opposite the longest side MO.
The largest angle is at O, opposite the shortest side NM.
As angle N is 90 degrees, the remaining angle at O must be the second-largest angle.
Yesterday, Juana sold 84 hot chocolate during her shift at work. If she worked from 7:00 am to 3:00 pm with an hour break for lunch, what was the average sold per hour?
Juana sold an average of 12 hot chocolates per hour during her 7-hour work shift (excluding her lunch break).
Explanation:The question asks us to calculate the average hot chocolate sold per hour by Juana during her shift. Juana worked an 8-hour day but took a 1-hour lunch break, leaving 7 hours of work time.
To find the average sold per hour, the total amount sold (84 hot chocolates) should be divided by the number of hours worked (7 hours). The calculation is as follows:
84 hot chocolates ÷ 7 hours = 12 hot chocolates per hour
Therefore, Juana sold an average of 12 hot chocolates per hour during her shift.
