What is the scale factor of the dilation?
Is the dilation an enlargement or a reduction?
Answers:
Scale Factor = 3/4
This is a reduction
======================================================
Explanation:
Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).
Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '
we have x = 4 jump to 4k which is the x coordinate of point R'
So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75
We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.
Answer:
A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

the sides of a rectangle are in the ratio 2:5. if the longer side of the rectangle is 25.5 in., what are it's width, perimeter, and area ?
Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches, the area is 260.1 inches.
Step-by-step explanation:
25.5/5=5.1
5.1*2=10.2
The width is 10.2 inches
25.5*2+10.2*2=71.4
The perimeter is 71.4 inches
20.5*10.2=260.1
The area is 260.1
Width=10.2 in. Perimeter=71.4 in. Area=and 260.1 in.

Rebecca is playing a video game that involves planting and cutting down trees. She moves up an energy level for each tree she plants, and she moves down a level for each tree she cuts. If Rebecca reaches energy level 10, she will earn bonus points.
Rebecca is currently at energy level 4. The results of her next 3 turns are:
Turn 1: 6 trees cut
Turn 2: 8 trees planted
Turn 3: 1 tree cut
3. What is Rebecca's energy level after Turn 2?
4. What is Rebecca's energy level after Turn 3? Will she earn bonus points after Turn 3? Explain why or why not.
Answer:
3. 6 energy points after turn 2
4. 5 energy points after turn 4
no bonus points cause she never reached 10 points

The figure shows a trapezium PQRS where RS = 17m and PS = 15m. If PT = 14m, and the area of trapezium is 196m2, Find the length PQ.
Answer:
PQ = 11 m
Step-by-step explanation:
In trapezium PQRS,
PQ and RS are parallel lines and PT is the perpendicular distance between the parallel lines
a = PQ
b =RS = 17 m
d = PT = 14 m
[tex]\frac{(a+b)*d}{2}= 196\\\\\frac{(PQ + 17)*14}{2}=196\\\\(PQ + 17) * 7 = 196\\\\PQ + 17 = \frac{196}{7}\\\\PQ + 17 = 28\\\\PQ = 28 - 17\\\\PQ = 11[/tex]

Solve the x
-9 (1/2x - 3) = 45
Answer:
=
−
3
6
7
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
-9 (1/2x - 3) = 45
Divide both sides by -9
1/2x - 3 = -5
Add 3 to both sides
1/2x = -2
multiply both sides by 2
x = -4
What is the value of x?
Answer:
28!
Step-by-step explanation:
soooooo its a 90 degree angle
2x+1+33=90
2x+34=90
-34
2x=56
x=28
Answer:
x = 28°
Step-by-step explanation:
As you see that the angle is an right angle where right angles = 90°
So,
(2x + 1) + 33 = 90°
Subtract 33 on both sides:
2x + 1 = 57
Subtract 1 on both sides:
2x = 56
Divide 2 on both sides:
x = 28°
The pacific ocean covers 1/3 of Earth surface the Atlantic Ocean cover 1/5 of Earth surface, what fraction of Earth surface is covered by both oceans?
Answer:
Here I answered it
Step-by-step explanation:
1/3 + 1/5
1 x 5/3 x 5 + 1 x 3/5 x 3
5/15 + 3/15 = 8/15
The part of earth covered by both of the oceans is 8/15
What is a fraction?A fraction represents part of a whole. When something is broken up into a number of parts, the fraction shows how many of those parts you have.
Given that, The Pacific Ocean covers 1/3 of the Earth surface the Atlantic Ocean covers 1/5 of the Earth surface,
To find the total area covered we will add both the area,
1/5+1/3
= 8/15
Hence, The part of earth covered by both of the oceans is 8/15
