Yes if you convert it into a rational number it will be -155/10
Answer:
No, he is not correct.
Step-by-step explanation:
0.23 × 2.07 = 0.4761
Multiply 0.23 and 2.07 to get 0.4761.
0.4761=0.04761
Compare 0.4761 and 0.04761.
False
Answer:
(x, y) ⇒ (2x, 2y)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.
Given that the inner circle has a radius of 1 r and the outer one has a radius of 2 r. To map the inner circle onto the outer circle, the inner circle would need to be enlarged. The scale factor is:
k = outer circle radius / inner circle radius = 2r / 1r = 2
A dilation with a scale factor of 2 would be needed to map the inner circle onto the outer circle.
That is:
(x, y) ⇒ (kx, ky)
Step-by-step explanation:
the answer is
2x+4x =90
6x=90
x=15°
