Answer: The translation rule that maps point D ( 7 , − 3 ) onto point D ' ( 2 , 5 )
is (x , y) → (x - 5 , y + 8)
Step-by-step explanation:
Let us revise the translation
If the point (x , y) translated horizontally to the right by h units then its image is (x + h , y)
If the point (x , y) translated horizontally to the left by h units then its image is (x - h , y)
If the point (x , y) translated vertically up by k units then its image is (x , y + k)
If the point (x , y) translated vertically down by k units then its image is (x , y - k)
(x , y) → (x ± h , y ± k) the right arrow symbol used to show the
translation from a point to its image
Example:
∵ P (0 , 0) → P' (1 , 2)
∴ The rule is (x , y) → (x + 1 , y + 2)
Let us find the translation rule that maps point D ( 7 , − 3 ) onto
point D' (2 , 5)
∵ Point (x , y) = (7 , -3)
∵ Its image after translation (x + h , y + k) = (2 , 5)
∴ x + h = 2
∵ x = 7
∴ 7 + h = 2
- Subtract 7 from both sides
∴ h = -5
∵ y + k = 5
∵ y = -3
∴ -3 + k = 5
- Add 3 to both sides
∴ k = 8
∴ The rule of translation is (x , y) → (x - 5 , y + 8)
The translation rule that maps point D ( 7 , − 3 ) onto point D ' ( 2 , 5 )
is (x , y) → (x - 5 , y + 8)

Answer:
Your answer for F will be 13.
Step-by-step explanation:
Take 11.2 and add it to 1.8, and you will get 13 and 13 will be the variable (f). So, f (13) - 1.8 = 11.2

Can you please check over my answer for volume and help me with the surface area?
Answers
Answer:
the surface area of the figure is 622 m ^2
the volume of the figure is 494 m ^3
Step-by-step explanation:
-you find the surface area for the rectangular prism and the triangular prism and add both answers.
- Rectangular prism S.A : 382 ^ 2 382m ^2 + 240m ^2 = 622 m ^2
- triangular Prism S.A : 240 ^ 2
-same thing with the volume,find the volume of the rectangular prism and the triangular prism and add those answers to find the total volume of your figure.
- Rectangular Prism Volume : 380 m^3 380 m ^3 + 114 m ^3 = 494 m ^3
- Triangular Prism Volume : 114 m ^3
formula for volume of a rectangular prism : V = w * l * h
formula for volume of a triangular prism : V = A * h
formula for surface area of a triangular prism simplified :
find the area of your base [area of the triangle on your triangular prism and since you have 2 multiply by 2,formula for area of 2 bases: A= 2 (1/2 * b*h) ) ]
next step-
formula for a surface area of a rectangular prism : 2 (w*l + l*h + h*w )
a-area w- width l-length
h-height s.a -surface area
What is the length of the line?
A) 8
B) 12
C) Square Root of 60
D) Square Root of 136
Answers
Hi there!
[tex]\large\boxed{\text{ D. } \sqrt{136}}[/tex]
Use the Pythagorean theorem to find the length of the line.
If we draw an imaginary right triangle using the given line as the hypotenuse, we can derive a height of 6 units and a length of 10 units.
Use the Pythagorean theorem equation:
c² = a² + b²
Plug in the height and length:
c² = 6² + 10²
Simplify:
c² = 36 + 100
c² = 136
Take the square root of both sides:
c = √136. The correct answer is D.
Answer: if I have to guess, the answer World be D) Square Root of 136.

======================================================
Explanation:
Extend the side that's 9.5 meters long out to the left so that you form a trapezoid on top and a rectangle underneath. The side we extended is now 5+9.5 = 14.5 meters long.
Let
A = area of the trapezoid up topB = area of the rectangle underneathThe goal is to find A+B
The trapezoid has the parallel sides of 14.5 and 10 meters. The height of the trapezoid is 28-20 = 8 meters. So we can say
Area of trapezoid = height*(base1+base2)/2
A = h*(b1+b2)/2
A = 8*(14.5+10)/2
A = 98
The rectangle has area of B = length*width = 5*20 = 100 square meters
Therefore,
total area = A+B = 98+100 = 198 square meters.

Which set of line segments cannot form a triangle?
20.2 m, 20.4 m, 20.6 m

12.8 m, 25.7 m, 35.9 m
35.6 m, 49.9 m, 83.2 m
Answers
Answer:
second option: 32.8 m, 48.2 m, 81.1 m
Step-by-step explanation:
20.2 m + 20.4 m = 40.6 m. which is bigger than 20.6 m. so yes
32.8 m + 48.2 m = 81 m. which is smaller than 81.1 m. so no
12.8 m + 25.7 m = 38.5 m. which is bigger than 35.9 m. so yes
35.6 m + 49.9 m = 85.5 m. which is bigger than 83.2 m. so yes
In a garden, 2/3 of the flowers are roses. Of the roses in the garden, 5/12 are yellow and the rest are red. What fraction of the flowers are red roses?
Answers
because 5/12 are yellow, the rest would be red. so 7/12. but total roses are only 2/3 of the whole garden.
tip: when you see "of" in a fraction problem, it means you can multiply them.
so, 7/12 OF 2/3 is just (7/12) * (2/3).
multiplying straight across and simplifying will get you to 7/18!
