The composition of similarity transformations that maps Triangle LMN to TriangleL'M'N is a dilation with a scale factor less than 1 and then a reflection. Opion A. This is further explained below.
Which composition of similarity transformations maps TriangleLMN to TriangleL'M'N'?Generally, In the case of a reflection across the y-axis, the y-coordinate of a point stays the same but the x-coordinate is changed into its inverse.
Triangle LMN has the coordinates (2, 1), (1, 1), and (1, 3).
(-4,-4) (-3,-4) (-3,-2).
In conclusion, Assuming that the coordinates (2, 1), (1, 1), and (1, 3) of Triangle LMN. This is the translation 5 units down (x,y-5): Two units to the right (x+2, y-5) of the coordinates (2,-4), (1,-4), and (1,-2): (4, -4), (3, -4), (3, -2)

Answer:
$254,567
Step-by-step explanation:
The houses market value is $152,740 and has a 60% assessment rate, the assessed valuation of this house would be $254,567. How we got this was by dividing the house total which is $152,740 by the assessment percentage rate which is 60 percent. Simply $152,740÷0.60

A fish tank with a rectangular base has a volume of 3360 cubic inches. the length of the tank is 14 inches and the width is 12 inches. the height of the tank is 20 inches. if one fluid ounce is 1.8 cubic inches how much water will the tank hold ? your answer should be in gallons.
Answer:
14.58 gallons
Step-by-step explanation:
The tank volume is 3360 in^3, which is the product of the base x length x height (14)(12)(29) = 3360 in^3.
We are given a conversion factor: 1 fluid oz = 1.8 in^3
We can write this as (1 fluid oz)/( 1.8 in^3).
Use this conversion factor to confert volume to fluid oz:
(3360 in^3)*((1 fluid oz)/( 1.8 in^3)) = 1867 fluid oz
There are 128 fluid oz/gallon. Make this into a conversion factor:
(1 gallon/128 fluid oz) [The conversion factor can be written with oz or gallon on the top - it makes no difference since the two values are equal to each other]
(1867 fluid oz)*((1 gallon/128 fluid oz) = 14.58 gallons
water the tank will hold = 14.583 gallons
What is cuboid ?A cuboid is a three-dimensional or solid shape. A cuboid is a convex polyhedron that has six rectangular faces, eight vertices, and twelve edges. Another name for a cuboid is a rectangular prism. A cube is a cuboid with six square faces. The basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
Given : A fish tank has a volume = 3360 cubic Inches.
The length of the tank is =14 inches
the width is = 12 inches.
The height of the tank is = 20 inches.
If one fluid ounce is = 1.8 cubic inches
Volume of tank = 14 * 12 * 20 = 3360 cubic inches
1.8 cubic inches = one fluid ounce
3360 cubic inches = 3360/1.8 fluid ounce
= 5600/3 fluid ounce
As we know,
1 gallons = 128 fluid ounces
water the tank will hold =( 5600/3 ) / 128
= 175 / 1 = 14.583 gallons
Therefore, water the tank will hold = 14.583 gallons

Step-by-step explanation:
since DE is parallel to the diameter RS, D and E are just a transformation of R and S, where R and S slid up the same distance on the circle arc.
therefore, RD = SE.
and therefore d is half of the supplementary angle to the angle DE (that means together the angle DE and the supplementary angle are 180°).
so,
d = (180 - 50)/2 = 130/2 = 65°
y-20 = 0.75(x-4) solve for y
Answer:
y = 0.75x + 17
Step-by-step explanation:
y - 20 = 0.75(x-4)
y - 20 = 0.75(x) + 0.75(-4)
y - 20 = 0.75x -3
y = 0.75x -3 + 20
y = 0.75x + 17
y - 20 = 0.75(x - 4) |add 20 to both sides
y = 0.75(x - 4) + 20we can simplified equation:
use the distributive property: a(b + c) = ab + ac
y = 0.75x - 0.75 · 4 + 20
y = 0.75x - 3 + 20
y = 0.75x + 17Mickey use three calculations to find how much he would spend on seven cartons of eggs 12 cartons of eggs cost $22.20 describe his error

What is the expression of g(x) when we perform the following sequence of transformations onto the parent function fx=x2:
a) Shift right 1 unit;
b) Compress horizontally by a factor of 2
The expression of function g(x) is [tex](\frac x2 - 1)^2[/tex]
How to determine the expression?The function is given as:
[tex]f(x) = x^2[/tex]
When the function is shifted right by 1 unit, the rule is:
f'(x) = f(x - 1)
So, we have:
[tex]f(x) = (x - 1)^2[/tex]
When the function is compressed horizontally by a factor of 2, the rule is:

Jaylen and ken started jogging from the same place in the opposite directions along a straight path. jaylen's speed was 30 m/min faster than ken's speed. both of them did not change their speeds throughout the jog. at the end of the jog, they were 13.6 km apart. jaylen jogged 2.4 km more than ken. what was ken's average speed?
The average speed of Ken is 70 m/min. Using the relation between the speed and distance, the required speed for Ken is calculated.
What is the relation between speed and distance?The relationship between speed S and distance D with a period T is formed as
S = D/T
Units: m/sec (basic unit)
Calculation:Given that,
Jaylen and Ken started jogging from the same place in opposite directions along a straight path.
This means, that the sum of distances traveled by both of them in opposite directions = 13.6 km (since it is given that at the end of their jogging, they are 13.6 km apart)
Consider,
The distance traveled by Jaylen = x km
Then the distance traveled by Ken = x - 2.4 km (since Jaylen jogged 2.4 km more than Ken)
Step 1: Finding the distance traveled by them:
x + x - 2.4 = 13.6
⇒ 2x = 13.6 + 2.4
⇒ 2x = 16
⇒ x = 8 km
So, the distance travelled by Jaylen = 8 km and by Ken = 8 - 2.4 = 5.6 km
Step 2: Finding the average speed traveled by Ken:
Since it is given that,
Jaylen's speed was 30 m/min faster than Ken's speed.
So,
For 30 m, the time = 1 min
then for 2.4 km i.e., 2400 m, the time = 80 min.
Therefore,
the average speed of Ken S = D/t
⇒ S = 5600 m / 80 min
∴ S = 70 m/min.
So, the average speed of Jaylen will be 70 m/min + 30 m/min = 100 m/min.
Thus, the average speed of Ken is 70 m/min.

22/7 was considered while choosing the square's side length, the area of just one side of the remaining paper which is a multiple of 7.
Calculate the area of just one side of the remaining paper. use 3.14 for the value of pi.Since the largest circle that can be encircled by a square has a diameter "d" equal to its side length, we may use "d" to conveniently calculate both the square's area and the circle's area.
The largest possibly circle has been cut from a piece of paper.
Square’s area = [tex]d^2[/tex]
Circle’s area =ᴨ[tex]d^2/4[/tex]
Simplifying-
(divide both area by [tex]d^2[/tex]) we find their ratio is 1:(ᴨ/4) or 4/ᴨ (square: circle), and the inverse, ᴨ/4 circle: square.
Therefore diameter of circle =14 cm.
Hence area of circle=πr2.
If you use 22/7 as an approximation for ᴨ, the circle’s area 22/28 of the square’s, the square’s area is 28/22 of the circle’s , it follows that the area outside the circle is (28–22)/28 of the square’s area, which is (28–22)/28 x 14 x14,
or 6/28 x 14 x 14,
or 3/14 x 14 x 14,

The area of the unshaded region of the circle will be 120π units squared.
The area of a sector of a circle of radius r having an angle a° is given by:
