Answer:
B 1/3 then reflection across y axis then move figure 2 units to down and 1 right.
Step-by-step explanation:
The figure ABC is bigger than FED so the scale factor is less than one since we are going to ABC to FED. Let look at corresponding sides, AB and FE. AB distance is 3. FE distance is 1 so let divide
[tex] \frac{fe}{ab} [/tex]
[tex] \frac{1}{3} [/tex]
The scale factor is 1/3.
The new points are at A'(-2,0) B'(-2,1) C'(-1,0).
Then we apply reflection.
Since FED is in the 4th quadrant, we are going to reflect across the y axis.
That becomes using formula
(x,y) goes to (-x,y) when reflecting across yaxis.
A''(2,0) B''(2,1) C''(1,0)
Now we will apply the translation. We can simply just move the figure 2 units down and 1 unit to the right.

If I run 50 yards, how much less did I run (in inches) than 50 meters?
Answer: 168.5 inches
50 yards = 1800 inches
50 meters = 1968.5 inches.
So, if you run 50 yards, you run 1968.5 - 1800, 168.5 inches less than 50 meters.

Construct the bisector of the following figures
Answer:
In these lessons, we will learn
how to construct an angle bisector of a given angle.
how to use an angle bisector to construct some angles for example, 90 degrees, 45 degrees, 60 degrees, 30 degrees, 120 degrees, 135 degrees, 15 degrees.
An angle bisector is a straight line that divides the angle into two equal parts.
Example: Construct an angle bisector for the following angle:
Solution:
Step 1 : Put the sharp end of your compasses at point B and make one arc on the line BC (point S) and another arc on line AB (point T).
Step 2 : Put the sharp end of the compasses at S and make an arc within the lines AB and BC. Do the same at T and make sure that the second arc intersects the first arc.
construct angle bisector
Step 3 : Draw a line from point B to the points of intersection of the 2 arcs. This line bisects ∠ABC.
construct angle bisector
The steps to construct an angle bisector can be summarized as follows:
1. From the vertex, draw an arc across both rays of the angle.
2. From each arc intersection draw another pair of arcs that intersect each other.
3. Draw a line from the vertex to the intersection point to form the angle bisector.

Answer: DC=30.5
Step-by-step explanation:
Use trigonometry to solve this question
sin=O/Hcos=A/Htan=O/A----------------------------------------------------------
First Step: find BD
- AB relative to 54° is [hypotenues]
- BD relative to 54° is [opposite]
- Therefore, we need to use O/H, which is Sin
- sin(54°)=O/20=20·sin(54°)=16.2
Second Step: Find DC
- DC relative to 28° is [adjacent]
- BD relative to 28° is [opposite]
- Therefore, we need to use O/A, which is tan
- tan(28°)=16.2/A=16.2/tan(28°)=30.5

Mr. Strand mowed 2/5 of his lawn. His son mowed 1/4 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answer: Mr. Strand mowed most of the lawn, and 7/20 of the lawn still needs to be mowed.
Step-by-step explanation:
Part 1:
We can use change the fractions so that they have equivalent denominators. The Least Common Denominator that the two fractions have is 20.
2/5 = 8/20.
1/4 = 5/20.
Because of this, Mr. Strand, who mowed 2/5 of the lawn, mowed most of the lawn.
Part 2:
8/20 + 5/20 = 13/20. Therefore, 7/20 of the lawn still needs to be mowed.
In conclusion, Mr. Strand, who mowed 2/5 of the lawn, mowed most of the lawn. 7/20 of the lawn still needs to be mowed.
Answer:
Step-by-step explanation:
0.65 of the lawn was mowed
Macy's is going out of business and is having a HUGE sale. A dress that originally costs $40 is now 40% off! What is the final price of the dress?

Please help with this right triangle problem
Given:
The figure of a right angle triangle.
To find:
The measure of side AB.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given triangle,
[tex]\cos B=\dfrac{BC}{AB}[/tex]
[tex]\cos (20^\circ)=\dfrac{7}{AB}[/tex]
[tex]\cos (20^\circ)AB=7[/tex]
[tex]AB=\dfrac{7}{\cos (20^\circ)}[/tex]
On further simplification, we get
[tex]AB=\dfrac{7}{0.93969}[/tex]
[tex]AB=7.449265[/tex]
[tex]AB\approx 7.45[/tex]
Therefore, the measure of AB is 7.45 units.

Use synthetic division to find all the factors of this polynomial
4x^3+5x^2-18x+9
Answer:
(x-1)(4x-3)(x+3)
Step-by-step explanation:
The factor of the polynomial 4x³ + 5x² – 18x + 9 will be (4x – 3), (x + 3), and (x – 1).
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The polynomial is given below.
⇒ 4x³ + 5x² – 18x + 9
Then the factor of the polynomial will be
⇒ 4x³ – 3x² + 8x² – 6x – 12x + 9
⇒ x²(4x – 3) + 2x(4x² – 3) – 3(4x – 3)
⇒ (4x – 3)(x² + 2x– 3)
⇒ (4x – 3)(x² + 3x – x – 3)
⇒ (4x – 3)(x + 3)(x – 1)
More about the factorization link is given below.

i need help :/

Answer:
Z=20 Degrees
Step-by-step explanation:
We know that all of the angles of a triangle add up to 180, so:
65+55+ Angle A = 180
Simplify:
120+ Angle A = 180
Subtract 120 from both sides:
Angle A = 60
If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:
60/3=20
Z=20 Degrees
Answer:
Angle E is 60 degrees
Step-by-step explanation:
So z is an angle.
That would be point E.
This triangle was dilatated so we can match it up with the larger one. In a dilation, angle measures do not change. So matching up the points E would be equal to A, which of course it the only one with an angle measure not given.
All you have to do is add up the two angle measures and subtract that by 180 (total of all angles combined).
So 65+55=120
180-120=60
Angle A is 60
Which makes angle E 60 as well
