For this case we propose a rule of three:
foot ------------->
hour
x -----------------------------------> 1 hour
Where "x" represents the amount of foot in one hour.

So, we have
foot every hour.
Answer:
foot every hour
The answer is 5 because 10 minus 5 is 5, so the difference is 5.
Given the triangles ABC and EDC
We will find the transformation that makes the triangles are similar
As shown: the triangles are reflected over the y-axis
the rule of the reflection over the y-axis will be as follows:

And as shown, the length of the side AB = 3 units
And the length of the side ED = 1 units
So,

So, the answer will be:
D) (x,y) ⇒ (-x, y)
E) (x,y) ⇒ (1/3 x, 1/3 y)
Answer:
Extended facts are basic addition facts multiplied by a power of 10, such as 10, 100, 1,000.
Step-by-step explanation:
Example: 7 + 6 = 13 (basic) 70 + 60 = 130 (extended) 700 + 600 = 1300 (extended).
