Answer:
77/180
Step-by-step explanation:
x = 0.42777....
Multiply by 1000 (the number of digits in decimal)
1000x = 427.7777......
100x = 42.7777...... {Now subtract}
900x = 385
x = 385/900
x = 77/180

Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact form:
[tex]y = \frac{7}{2} , -\frac{7}{2}[/tex]
Decimal form:
[tex]y = 3.5,-3.5[/tex]

Quadrilateral ABCD has both reflection and rotation symmetry. What type of quadrilateral could it
be? Show or explain.
Answer:
Rhombus
Step-by-step explanation:
So if |AB| = |BC| then ABCD is a rhombus and has a second line of reflective symmetry, namely \overleftrightarrow{BD}. Quadrilateral ABCD is what is called a kite.
Since ℓ contains two vertices of ABCD the other two must be reflections of one another about ℓ. In the picture ℓ goes through A and C and D=rℓ(B). So rℓ interchanges AD¯¯¯¯¯¯¯¯ and AB¯¯¯¯¯¯¯¯ and also interchanges CB¯¯¯¯¯¯¯¯ and CD¯¯¯¯¯¯¯¯. So if |AB|=|BC| then ABCD is a rhombus and has a second line of reflective symmetry, namely BD←→. Quadrilateral ABCD is what is called a kite. Note that we have implicitly used the fact that ABCD is convex: without this hypothesis, the vertex C could be reflected over BD←→, giving a non convex quadrilateral with exactly one line of symmetry.
Rectangle has rotational and reflectional symmetry.
What is Quadrilateral?
A quadrilateral is a polygon having four sides, four vertices and four angles.
Given that;
Quadrilateral ABCD has both reflection and rotation symmetry.
Now,
A rectangle ABCD has a reflection symmetry because it has two line of symmetry.
And, Rotational symmetry is defined as the number of times an object is exactly identical to the original object in a complete 360° rotation.
So, Rectangle ABCD has rotational symmetry.
Thus, Rectangle has rotational and reflectional symmetry.

Answer:
[tex] \dfrac{4r^6}{st^8} [/tex]
Step-by-step explanation:
[tex] (4r^{-2}st^4)(r^{-4}st^6)^{-2} = [/tex]
Use laws of exponents to simplify the right set of parentheses.
[tex]= (4r^{-2}st^4)(r^{8}s^{-2}t^{-12})[/tex]
Now use the law of exponents for a product of powers with the same base.
[tex] = 4r^6s^{-1}t^{-8} [/tex]
Finally, use the definition of a negative exponent.
[tex] = \dfrac{4r^6}{st^8} [/tex]

Answer:
s = 19°Step-by-step explanation:
The angles that are directly opposite to each other are known as opposite angles. They are also termed as vertical angles or vertically opposite angles and are equal to each other.
so
106 = 6s - 8
106 + 8 = 6s
114 = 6s
s = 114 : 6
s = 19°
-----------
check
6 * 19 - 8 =
106°

It took a car 2 days to travel 2274 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)
Answer:
47 mph
Step-by-step explanation:
1 day = 24 hours, so 2 days = 48 hours.
2274/48 (2274 miles per 48 hours, simplify!) This equals 47.375. Round it down to 47 mph.
This is assuming the car took no breaks.

Answer:
Option 4: 0
Step-by-step explanation:
Given the function, f(x) = 3x, and the domain. {-3, 1, 4}:
Substitute the values of each domain as inputs into the function:
x = -3f(-3) = 3(-3)
f(-3) = -9
x = 1f( 1 ) = 3( 1 )
f( 1 ) = 3
x = 4f(4) = 3(4)
f(4) = 12
Therefore, the correct answer is option 4) 0, because there is no input value that provides an output of 0. You were only given three domain values that provided its corresponding outputs.

Answer:
60 square km
Step-by-step explanation:
First, seperate the figure into two as a rectangle and a trapezium by drawing a line from the vertex between the lines which are 8km and 5km long until it reaches the line on the bottom. (11km) Then, find the area of the rectangle by multiplying 8 by 6, which gives an answer of 48 square km. Then, find the area of the trapezium using the equatiuon 1/2 (a+b) h. Here, a and b are the two parallel lines of the trapezium, which are the lines 2km and 6 km long, and h means the perpendicular height which is 3km long (by substracting 8 from 11, you get 3). you get the answer as 12 square km. finally, add up 12 and 48 to get 60 square km.
