1. 10x8 =80cm
2. 2.5 x 4.33=10.825ft triangles is base x height so it is half of 5 which is 2.5 to get the base number
3. 11x13= 143 ft
4. 8.5x12=102m
7. 12x 6 =72cm
8. (10x3)1/2=
30x1/2= 15in
He see a circle, so you need to find the area.
A = π * r²
A = π * 12²
A = 3.14 * 144 =
A = 452.16 miles²
For the element to be congruent only rotations, reflections or translations are allowed to be applied
1)
(x, y) → (x, –y)=reflection
(x, y) → (x + 5, y)=translation
(x, y) → (–x, y)=reflection
->is congruent
2)
(x, y) → (x + 1, y)=translation
(x, y) → (–x, –y)=reflection
(x, y) → (2x, y)=scaling->can't be congruent
3)
(x, y) → (0.5x, 0.5y)=scaling->can't be congruent
(x, y) → (x, –y)
(x, y) → (x, y + 8)
4)
(x, y) → (x – 4, y)=translation
(x, y) → (x, y + 3)=translation
(x, y) → (3x, 3y)=scaling->can't be congruent
so 1) is the only series of transformations with a congruent solution
Answer:
3.1 3.25 3.33 3.4
Step-by-step explanation:
Answer:
-8
Step-by-step explanation:
8ʸ = 16ʸ⁺²
(2³)ʸ = (2⁴)ʸ⁺²
2³ʸ = 2⁴ʸ⁺⁸
3y = 4y + 8
y = -8
