Answer:
is it 5y/8_5y/16 or 5y/8-5y/16 ?
Step-by-step explanation:
Answer:
[tex]\frac{5y}{16}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5y}{8}[/tex] - [tex]\frac{5y}{16}[/tex]
To subtract the fractions we require them to have a common denominator.
Multiply numerator/ denominator of [tex]\frac{5y}{8}[/tex] by 2
= [tex]\frac{5y(2)}{8(2)}[/tex] - [tex]\frac{5y}{16}[/tex]
= [tex]\frac{10y}{16}[/tex] - [tex]\frac{5y}{16}[/tex]
Now subtract the numerators, leaving the denominator
= [tex]\frac{10y-5y}{16}[/tex]
= [tex]\frac{5y}{16}[/tex]
6. One of the transformations above was a dilation by a scale factor of k. The scale factor is the multiplicative amount that the picture has been enlarged. To calculate it, divide any length on B by the corresponding length on A. Use your ruler to make these measurements and then calculate the scale factor of the dilation. Round to the nearest tenth.
Answer:
well it is b
Step-by-step explanation:
well I tried my best
When a figure or a shape is dilated, the size of its image will either be enlarged or compressed.
The scale of dilation from A to B is 1.5
See attachment for the image that completes the question.
Using a ruler, we have the following measurements
[tex]\mathbf{A = 1\ inch}[/tex]
[tex]\mathbf{B = 1.5\ inches}[/tex]
The scale factor (k) from A to B is:
[tex]\mathbf{k = \frac BA}[/tex]
This gives
[tex]\mathbf{k = \frac {1.5\ inches}{1\ inch}}[/tex]
[tex]\mathbf{k = \frac {1.5}{1}}[/tex]
[tex]\mathbf{k = 1.5}[/tex]
Hence, the scale factor (k) from A to B is 1.5

(c) angle EOA
(d) angle AOH
Step-by-step explanation:
(b) The rays of vertical angles are opposites that form intersecting lines.
The opposite of ray OG is OF. The opposite of ray OB is OA, so the vertical angle to GOB is angle FOA.
__
(c) The opposite of ray OB is OA, so the supplement to angle EOB is angle EOA.

Comment on supplementary angles
Angles that form a linear pair are supplementary. Angles do not have to form a linear pair to be supplementary. They merely have to have a sum of 180°. Here, the supplementary angles of interest do form a linear pair, so finding the other angle of the pair means only finding the other point that names the line being formed by the pair.

What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
A toy robot moves 10 feet in 12 seconds at a constant speed.
Now,
At a constant speed,
In 12 second = 10 feet
So, In 1 second = 10 / 12 feet
= 0.83 feet
Thus, The robot move 0.83 feet in one second.

Take the values as coordinates in form of {x, y} , to have the following;
{0,0} , {2,3} , {4,6}
Find the slope using the coordinates as;
m=Δy/Δx
m=3-0/2-0 = 3/2
The slope m = 3/2
So from the answer choices, the coordinates that can give a slope of 3/2 will be:

The measure of angle W is 100°, and the measure of angle Z is 68°. A triangle has angles X, Y, Z. The exterior angle to angle X is W. What is the measure of angle Y? 12° 32° 80° 168°
The triangle has three angles X, Y, Z. The measure of angle Y is, 32°. So option B is correct.
What is an angle ?An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
Given that,
The measure of angle W is 100°,
And the measure of angle Z is 68°
The exterior angle to angle X is W
The measure of angle Y = ?
If the exterior angle to angle X is W then it can be written as,
angle X = 180° - W
= 180° - 100°
= 80°
angle Z = 68°
It is known that,
sum of all the interior angles of the triangle is 180°
X + Y + Z = 180°
80° + Y + 68° = 180°
Y = 32°
Hence, the value of angle Y is 32°

Which is the algebraic representation for a rotation 180° clockwise?
A. Y,X
B. -y,x

D. -x-y
The required algebraic representation for a rotation 180° clockwise is -x, -y. Option D is correct.
What is the transformation of geometry over the coordinate plane?Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.
here,
When rotation 180° clockwise takes place then the sign of the coordinate is reversed as if it is positive then it becomes negative and vice versa.
So the algebraic representation for a rotation 180° clockwise of (x, y) is (-x, -y).
Thus, the required algebraic representation for a rotation 180° clockwise is -x, -y. Option D is correct.

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used.
In the figure, p || q and r || s. Match each pair of congruent angles with the reason for their congruency.
Linear Pair Theorem
∠13 ≅ ∠16
corresponding angles for parallel lines p and q cut by the transversal r
∠1 ≅ ∠5
corresponding angles for parallel lines r and s cut by the transversal q
corresponding angles for parallel lines p and q cut by the transversal s
Vertical Angles Theorem
∠5 ≅ ∠13
∠10 ≅ ∠14
Answer:
got them all correct
Step-by-step explanation:
Congruent angles within two parallel lines are either vertical angles or corresponding angles. The reason for the congruence of the given angles are:
[tex]\angle 13[/tex] and [tex]\angle 16[/tex]
Reason: vertical angle theorem
[tex]\angle 1[/tex] and [tex]\angle 5[/tex]
Reason: corresponding angles for parallel lines p and q, cut by transversal r
[tex]\angle 5[/tex] and [tex]\angle 13[/tex]
Reason: corresponding angles for parallel lines r and s, cut by transversal q
[tex]\angle 10[/tex] and [tex]\angle 14[/tex]
Reason: corresponding angles for parallel lines p and q, cut by transversal s
From the given figure, we have the following:
Line p || Line q --- > This means that lines p and q are parallel
Line r || Line s --- > This means that lines r and s are parallel
From the attached figure, [tex]\angle 13[/tex] and [tex]\angle 16[/tex] are vertical angles.
Vertical angle theorem states that vertical angles are congruent.
So, the reason for the congruence of [tex]\angle 13[/tex] and [tex]\angle 16[/tex] is vertical angle theorem
[tex]\angle 1[/tex] and [tex]\angle 5[/tex] are corresponding angles of lines p and q, where line r passes through lines p and q.
Corresponding angles are congruent.
So, the reason for the congruence of [tex]\angle 1[/tex] and [tex]\angle 5[/tex] is that corresponding angles for parallel lines p and q, cut by transversal r
[tex]\angle 5[/tex] and [tex]\angle 13[/tex] are corresponding angles of lines r and s, where line q passes through lines r and s
So, the reason for the congruence of [tex]\angle 5[/tex] and [tex]\angle 13[/tex] is that corresponding angles for parallel lines r and s, cut by transversal q
[tex]\angle 10[/tex] and [tex]\angle 14[/tex] are corresponding angles of lines p and q, where line s passes through lines p and q
So, the reason for the congruence of [tex]\angle 10[/tex] and [tex]\angle 14[/tex] is that corresponding angles for parallel lines p and q, cut by transversal s
