Answer:
A. trapezoid
Step-by-step explanation:
A trapezoid does not have rotational symmetry . It would have to rotate 360 degree to look the same
An equilateral triangle has 120 degree rotational symmetry
A regular pentagon has 72 degree rotational symmetry
A rectangle has 180 degree rotational symmetry

The angles of a triangle are in the ratio 2:3 and the third angle is 2/3 of a right angle. Find all angles in degrees.
Answer:
Angles are 60 , 48 , 72
Step-by-step explanation:
Third angle = [tex]\frac{2}{3}[/tex] of right angle
[tex]=\frac{2}{3}*90\\\\=2*30\\\\= 60[/tex]
Ratio of two angles = 2 : 3
The two angles are 2x , 3x
2x + 3x + 60 = 180 {Angle sum property of triangle}
5x + 60 = 180 {Subtract 60 from both sides}
5x = 180 - 60
5x = 120
x = 120/5
x = 24
2x = 2* 24 = 48
3x = 3*24 = 72
Let the angles be 2x, 3x and (2/3)×90
ATQ
2x + 3x + (2/3)×90 = 180
5x + 60 = 180
5x = 180 - 60
x = 120/5
x = 24
Therefore the angles are
48, 72 and 60 respectively

triangles help pls!!
Answer:
x = 60
Step-by-step explanation:
The single dashed line represents congruent side lengths.
If every side of a triangle has a single dashed line then all of the sides are congruent meaning that the triangle is an equilateral
Equilateral triangles have all congruent side lengths and angles
In an equilateral triangle each angle has a measure of 60 degrees
So x = 60
Answer:
Step-by-step explanation:
A parallelogram is divided into two triangles, both triangles having equal sides.
So triangles are equilateral..In equilateral triangles, the angles are also equal..the interior angles of a triangle are 180 degrees..
180 ÷ 3 = 60 degree---> x:60°

4y2 - 12y
Step-by-step explanation:
2+4y-16y+32(Combine like-terms)
2−12y+32(Combine like-terms)
Answer:
The answer is [tex]4y^{2} -12y[/tex]
Step-by-step explanation:
To simplify the polynomial, start by combining like terms. Add [tex]y^{2}[/tex] and [tex]3y^{2}[/tex] to get [tex]4y^{2}[/tex]. Then, subtract [tex]16y[/tex] from [tex]4y[/tex] to get [tex]-12y[/tex]. Finally, the simplified answer is [tex]4y^{2} -12y[/tex].
Write if the statement presented is "True" or "False." If False, Justify. "The simplified ratio of 27:36 is 4: 3"
Answer:
FALSE. isn't it supposed to be 3 : 4.
Step-by-step explanation:
Simplified would be 27÷ 9 =3 and 36 ÷ 9 =4
============================================================
Explanation:
The ratio 4:3 has the first part (4) larger than the second part (3)
The ratio 27:36 has it flipped around, where the second part is the larger item this time.
Based on this alone, we can see that there's no way that 4:3 is the same as 27:36
--------------
Another way you can look at it is to divide both parts of 27:36 by the GCF 9
27/9 = 336/9 = 4The ratio 27:36 fully reduces to 3:4 and not 4:3. The order matters.
--------------
Or you could go in verse of the previous section. Multiply both parts of 4:3 by 9
9*4 = 369*3 = 27So the ratio 4:3 is equivalent to 36:27 which is not the same as 27:36. Again, the order is important.
--------------
Yet another approach:
Treat the ratios like fractions. If they were equal, then 27/36 = 4/3 would be true.
Cross multiplying leads to 27*3 = 36*4 and that becomes 81 = 144 which is false. So saying 27:36 reduces to 4:3 is also false
Suppose a river flows south to north at a velocity of 1 m/s, and a motorboat traverses the river from east to west at a speed of 2.5 m/s. At what angle should the boat be oriented south, relative to the westward direction, such that the boat will be traveling due west? Round to the nearest degree.
Answer: [tex]24^{\circ}[/tex]
Step-by-step explanation:
Given
River is flowing from south to North with a velocity of [tex]u=1\ m/s[/tex]
Motor boat traverses the river from east to west at a speed of [tex]v=2.5\ m/s[/tex]
South component of boat velocity must compensate the river velocity in order to travel in west direction.
[tex]\therefore v\sin \theta=u\\\\\Rightarrow 2.5\sin \theta=1\\\\\Rightarrow \sin \theta=\dfrac{2}{5}\\\\\Rightarrow \theta=23.57^{\circ}\approx 24^{\circ} \text{south of west}[/tex]

According to the synthetic division below, which of the following statements are true? Check all that apply
The true statements are A , B , E
What is division?It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Here, In the synthetic calculation we use the coefficient of the dividend
with the factors of the function
∴ 2 , -2 , -12 are the coefficient of the dividend 2x² - 2x - 12
∵ The divisor is 3
∴ x = 3 is a root of F(x) = 2x² - 2x - 12
∵ x = 3 is the root of F(x) = 2x² - 2x - 12
- Subtract the two sides by 3
∴ x - 3 = 0
∴ (x - 3) is a factor of the dividend F(x) = 2x² - 2x - 12
- The quotient is the last line of the synthetic division
∴ The coefficients of quotient are 2 , 4
- The quotient is 1 degree less than the dividend
∵ The degree of the dividend is 2
∴ The degree of the quotient is 1
∴ The quotient is 2x + 4
* Lets check the answers to chose the write statements
A. The number 3 is a root of F(x) = 2x² - 2x - 12 ⇒ true
B. (x - 3) is a factor of 2x² - 2x - 12 ⇒ true
E. (2x² - 2x - 12) ÷ (x - 3) = 2x + 4 ⇒ true
Thus, the true statements are A , B , E.

Answer:
[tex](x-\frac{1}{2})^2=\frac{81}{4}[/tex]
Step-by-step explanation:
Hi there!
[tex]x^2-x-20=0[/tex]
This equation is written in the form [tex]ax^2+bx+c=0[/tex]. First, use partial factoring:
[tex](x^2-x)-20=0[/tex]
For x^2-x, the b value is -1 in [tex]ax^2+bx+c[/tex]. To complete the square, take the square of half of 1 and add it in the parentheses as the c value:
[tex](x^2-x+\frac{1}{2}^2 )-20=0[/tex]
However, when adding values to one side of the equation, we must to the same to the other side:
[tex](x^2-x+\frac{1}{2}^2 )-20=\frac{1}{2}^2[/tex]
Complete the square:
[tex](x-\frac{1}{2})^2-20=\frac{1}{4}[/tex]
Move 20 to the other side
[tex](x-\frac{1}{4})^2=\frac{1}{4}+20\\(x-\frac{1}{2})^2=\frac{81}{4}[/tex]

6(x – 1) = 9(x + 2)
how do i get this right
Answer:
x = -8
Step-by-step explanation:
6(x – 1) = 9(x + 2)
Add 6 to both sides
6x - 6 + 6 = 9x + 18 + 6
Simplify
6x = 9x + 24
Subtract 9x from both sides
6x - 9x = 9x + 24 - 9x
Simplify
-3x = 24
Divide both sides by: -3
-3x/-3 = 24/-3
Simplify
x = -8

James and his family spend a morning picking peaches. They fill several bags. This line plot shows the weight of each bag. How many more pounds does one of the heaviest bags weigh than one of the lightest bags? Enter your answer as a fraction in simplest form by filling in the boxes.
Answer:
The answer is "[tex]1\frac{1}{2}[/tex]"
Step-by-step explanation:
Please find the graph file of the question in the attachment.
Its first step is the lightest and heaviest evil. [tex]4 \frac{1}{4}[/tex] is the lightest bag, and [tex]5 \frac34[/tex] is the heaviest bag. To remove it now, it is not permissible to remove it as a mixed fraction, therefore convert each fraction into an improper fraction by multiplying the whole integer to the numerator, then adding a numerator to this amount, multiplied by the numerator. Follow those steps to find out [tex]4 \frac{1}{4}[/tex] is the wrong part.
[tex](4\times 4+1=17) \ so\ 4\frac14=\frac{17}{4}.[/tex] The process is the same for [tex]5 \frac34 (5\times 4+3=23) \ so \ 5 \frac34= \frac{23}{4}.[/tex]
You now deduce the numerator but just not the negative, to deduct both. You subtract, as the question is raised far as[tex]\frac{23}{4}-\frac{17}{4} =\frac{6}{4}[/tex] is involved. The last stage is that this is transformed into blended families, dividing its count by the denominator, 6 divided by 4 is identical to 1.5. 1 is a full amount so you don't modify it, but you do need to change the 5 decimals to [tex]1.5=1 \frac{5}{10}[/tex] and the last step is [tex]1\frac{1}{2}[/tex]to reduce.

a triangle has the angles ( x+10), (x+5) and x. i need to solve for x, i have no idea how to get the answer please help.
Answer:
x= 33
Step-by-step explanation:
Since the sum of all 3 angles in a triangle is 180°,
(x +10)° +(x +5)° +x°= 180° (∠ sum of ∆)
Simplify:
3x +15= 180
-15 on both sides:
3x= 180 -15
3x= 165
Divide both sides by 3:
x= 165 ÷5
x= 33
