Answer:
per month means we divide by the months
here is our formula
we do 48.9-29.7 to see the increase, and divide by the months to see how much per month
(48.9-29.7)/8
We get 2.4, meaning the average weight increase per month is 2.4

Answer: *An image created by a reflection will always be congruent to its pre-image.
*Corresponding angles and segments are always congruent in a reflection of a figure.
*An image and its pre-image are always the same distance from the line of reflection.
Step-by-step explanation:
Since, reflection is a rigid transformation therefore, it preserves the shape of the figure and create congruent images.
And we know that if if two figures are congruent then their corresponding angles and sides are congruent.
Reflection maps a figure to create its mirror image, and the distance of object and image is always equal from the mirror, therefore "An image and its pre-image are always the same distance from the line of reflection."
Add all the times together:
10 + 25 + 15 = 50 minutes total.
For the ratio divide the time for weights by total time:
25/50 which reduces to 1/2
The ratio is 1/2
