Answer:
(- 18, - 2 )
Step-by-step explanation:
Since the dilatation is centred at the origin then multiply each of the original coordinates by the scale factor for image, that is
(- 9, - 1 ) → (2 × - 9, 2 × - 1 ) → (- 18, - 2 )
Given:
A figure in which a transversal line intersect the two parallel lines.
To find:
The missing value for the equation 
Solution:
In the given figure, the two parallel lines are line ED and line AB, and CD is the transversal line.
Angle BPC and angle BPD lie on a straight line CD. So,
(Supplementary angles)
Angle APD and angle BPD lie on a straight line AB. So,
(Supplementary angles)
Therefore, the required complete equations are
and
.
In a ratio of 7:3, for every 7 adults you have 3 children. So 30% of the total are children. I.e. if you have 10 people .7 times (10) are adults or 7 and .3 times (10) are children or 3. So for 370 people, .3 times 370 are children, or 111.
Answer:
