what is the final transformation in the composition of transformations?
Answer:
A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines).

find the measures of the angles labeled in the figure on the right
Answer:
Step-by-step explanation:
EFD = 90* (straight line = 180, and other angle is 90)
EHF = 180-52 = 128* (again straight line)
HFG = 90-32 = 58* (its a right angle (can tell by the square angle) = 90*)
G = 180 - 52 - 58 = 70* (angles in triangle = 180)
E = 180 - 32 - 128 = 20* (angles in triangle = 180)
Help if u understand pleas and thanks
Answer:
3f
Step-by-step explanation:
f+f+f=3f
since every f has the same value
example
2+2+2=3(2)
6=6
Answer:
3f
Step-by-step explanation:
There are three f's added together, which makes 3f. If you had multiplied them all it would've been f^3, if you had divided f by 3 you would have f/3, and if f=1 it would've just been 3. This is why 3f is the best answer here.
Hope this helps :)

Find the measure of the missing angles.
56°
102°
d
e
f
Answer:
Step-by-step explanation:
d = 102°
e = 56°
f = 22°
The measurement of each of the angle is -
∠e = 56°
∠d = 102°
∠f = 22°
What are intersecting lines?When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measureGiven are the intersecting lines as shown in the image.
We can write that -
∠e = 56° {vertically opposite angles}
∠d = 102° {vertically opposite angles}
∠f = {180 - (102 + 56)} {vertically opposite angles}
∠f = 22°
Therefore, the measurement of each of the angle is -
∠e = 56°
∠d = 102°
∠f = 22°

At a farm the ratio of cows to horses was 9 : 8 .If there were 45 cows at the farm,how many horses were there?
Answer:
40
Step-by-step explanation:
there are 9 cow for ever 8 horses
45 is 5 sets of 9 (45/5 = 9)
so to make this ratio equal you have to multiply the amount of horses by 5 too
8*5=40
40 horses
The mass of the Eiffel Tower is about 9.16 ⋅ 10^6 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 10^8 kilograms. Approximately how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower? Show your work and write your answer in scientific notation.
Answer:
by [tex]\bf 7.96 *10^6[/tex] , the mass of the golden gate is larger than the Eiffel Tower
Step-by-step explanation:
[tex]\large \boldsymbol {} \sf 8,05\cdot 10^8-9,16\cdot 10^6 = 805\cdot 10^6-9,16\cdot 10^6 = \\\\ 10^6(805-9,16)=10^6\cdot 795,86 \\\\ Standart \ form \ 10^6\cdot 795,86 \approx 10^8\cdot 7,96 \ kg[/tex]
Answer:
7.96 × 10⁸ kg moreStep-by-step explanation:
Subtract the mass Eiffel Tower from the mass Golden Gate Bridge:
8.05 × 10⁸ - 9.16 × 10⁶ = (805 - 9.16) × 10⁶ = 795.84 × 10⁶ =7.96 × 10⁸ kgPlease help me asap with explanation please

Find the values of x and y.
Answer:
X = 62.5 Degrees, Y = 60 Degrees.
Step-by-step explanation:
There is always 180 degrees in angles.
[ X ]
180 - 65 = 115
115 - 55 = 60
[ Y ]
180 - 55 = 125
125 / 2 = 62.5

3+x=2–3x how many solutions and the answer thank you
Answer:
[tex]1[/tex] solution
Step-by-step explanation:
Let's try to solve this and see where we get.
We can add 3x to both sides of the equation to get [tex]3+4x=2[/tex].
We can then subtract 3 from both sides of the equation to get [tex]4x=-1[/tex].
We lastly divide both sides of the equation by 4 to get [tex]x=-1/4[/tex].
Because all of our steps are reversible(for instance, when we divide by 4, we can multiply(the "reverse" of division) by 4, so dividing by 4 is reversible), there is only [tex]\boxed{1}[/tex] solution, [tex]x=-1/4[/tex].

could a triangle have angle measures of 112° 57° and 11°? explain hw u know
The additional of a triangle's degree measure will always equal 180˚
When the question asks you if a triangle with 112˚, 57˚, and 11˚, you have to add them up and make sure they equal to 180˚
In this case, 112˚ + 57˚ + 11˚ DO add up to 180˚, and is indeed a triangle.
Write the word sentence as an inequality
6 times a number x is at most 47
Writing as a word sentence, the inequality is:
[tex]6x \leq 47[/tex]
6 times a number x is 6 multiplied by x, that is: [tex]6x[/tex].At most 47 means that it is less than, or equals, to 47, hence:[tex]6x \leq 47[/tex]
Hence, the desired inequality, from the given word sentence, is:

9/20 - 7/15=
help guys plsss need na now .,.
Answer:
-1/60
Step-by-step explanation:
9/20-7/15=27/60-28/60
=-1/60
Answer:
-1/60
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(9/20, 7/15) = 60
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(9/20×33)−(7/15×44)
Complete the multiplication and the equation becomes
27/60−28/60
The two fractions now have like denominators so you can subtract the numerators.
Then:
27−28/60=−1/60
This fraction cannot be reduced.
Therefore:
9/20−7/15=−1/60

0.4x + 0.3y = 1.7
0.7x - 0.2y = 0.8
Solve it by using substitution method.
Step-by-step explanation:
[tex] \green{\large\underline{\sf{Solution-}}}[/tex]
Given pair of linear equations are
[tex]\rm :\longmapsto\:0.4x + 0.3y = 1.7 \\ \\ \rm :\longmapsto\:0.7x - 0.2y = 0.8[/tex]
can be rewritten as on multiply by 10,
[tex]\rm :\longmapsto\:4x + 3y = 17 - - - - (1)\\ \\ \rm :\longmapsto\:7x - 2y = 8 - - - - - (2)[/tex]
From equation (2)[tex]\rm :\longmapsto\:2y = 7x - 8[/tex]
[tex]\rm\implies \:\boxed{\tt{ y = \frac{7x - 8}{2}}} - - - - (3) [/tex]
On substituting the value of y in equation (1), we get
[tex]\rm :\longmapsto\:4x + 3\bigg( \dfrac{7x - 8}{2} \bigg) = 17[/tex]
[tex]\rm :\longmapsto\:\dfrac{8x + 21x - 24}{2} = 17[/tex]
[tex]\rm :\longmapsto\:29x - 24 = 34[/tex]
[tex]\rm :\longmapsto\:29x = 34 + 24[/tex]
[tex]\rm :\longmapsto\:29x = 58[/tex]
[tex]\bf\implies \:x = 2 - - - - (4)[/tex]
On substituting x = 2 in equation (3), we get
[tex]\rm :\longmapsto\:y = \dfrac{7 \times 2 - 8}{2} [/tex]
[tex]\rm :\longmapsto\:y = \dfrac{14 - 8}{2} [/tex]
[tex]\rm :\longmapsto\:y = \dfrac{6}{2} [/tex]
[tex]\bf\implies \:y = 3[/tex]
So, we get
[tex]\begin{gathered}\begin{gathered}\bf\: \rm :\longmapsto\:\begin{cases} &\bf{x = 2} \\ \\ &\bf{y = 3} \end{cases}\end{gathered}\end{gathered}[/tex]
VerificationFrom equation (1),
[tex]\rm :\longmapsto\:0.4x + 0.3y = 1.7[/tex]
On substituting the value of x and y, we get
[tex]\rm :\longmapsto\:0.4(2) + 0.3(3) = 1.7[/tex]
[tex]\rm :\longmapsto\:0.8 + 0.9 = 1.7[/tex]
[tex]\rm :\longmapsto\:1.7 = 1.7[/tex]
Hence, Verified▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
