The distance from the park to the grocery store is 0.9 mile.
Ezra runs 8 tenths of that distance and walks the rest of the way. The distance
ezra runs can be solve by multiplying 8/10 to the total distance.
X = 0.9(8/10)=0.72 mile
Answer:


Step-by-step explanation:
Given

Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:

Solving (b): The slope and its interpretation
A function is represented as:

Where:

By comparing:
to 

So:

<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
A: Multiply by 12
The 1/2 is already multiplied by the bh, so in order to "undo" that multiplication, you have to do the opposite, which is to divide.
