Alright, lets get started.
In the question given that glacier receded 4 feet a day for a period of 25 days.
Which shows in 1 day, it recedes = 4 feet
means in 1 day, the height of the glacier gets shorter = 4 feet
So, in 25 days, the height of the glacier gets shorter = 4 * 25
So, in 25 days, the height of the glacier gets shorter 
feet
It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer
Hope it will help :)
270 minutes = 4,5 hours = 4 hours and 30 minutes
60 minutes = 1 hour
63 miles per 270 minutes
x miles per 1 hour = 60 minutes
![\dfrac{63[miles]}{x[miles]} = \dfrac{270[minutes]}{60[minutes]}](https://tex.z-dn.net/?f=%5Cdfrac%7B63%5Bmiles%5D%7D%7Bx%5Bmiles%5D%7D%20%3D%20%5Cdfrac%7B270%5Bminutes%5D%7D%7B60%5Bminutes%5D%7D)
![x=14[miles]](https://tex.z-dn.net/?f=x%3D14%5Bmiles%5D)
His average speed is 14 miles per hour.

The correct answer is 1/a^7 (b)
Answer:
The scale factor of all radii of circle Y to all radii of circle Z is 2.5
Step-by-step explanation:
we know that
The radius of circle Y is 4 units
The radius of circle Z is 10 units
To find the scale factor of all radii of circle Y to all radii of circle Z, divide the radius of circle Z by the radius of circle Y
10/4=2.5
