In 2073 BS father's age was 7 times his daughter devyani's age. In 2081 BS father's age will be 3 times only his daughter's age.

Anna007 [38]

Answer:

2069.

Step-by-step explanation:

Let Devyani's age in 2073= x years and y be her fathers age Then:

y = 7x

- and in 8 years time ( 2081) we have:

y + 8 = 3(x + 8)

y = 3x + 24 - 8

y = 3x + 16. Eliminating y from the 2 equations:

7x = 3x + 16

4x = 16

x = 4.

So in 2073 she was 4 years old

Therefore she was born in 2069.

Snezhnost [94]

Answer: $scale\ factor=5$

Step-by-step explanation:

By definition, a Dilation is a transformation in which the image has the same shape as the pre-image but size changes.

The center of dilation is a fixed point in the plane, and the scale factor is the ratio of the corresponding sides of the image to the pre-image.

Based on the information provided in the exercise, you know that:

$UE = 2\ cm\\\\U'E'=10\ cm$

Thererefore, you can determine that the scale factor is:

$scale\ factor=\frac{10\ cm}{2\ cm}\\\\scale\ factor=5$
