Ok to find the difference, you have to subtract. 12.41-11.85=0.56. It was 0.56s faster.
Answer:
Simplified form of 
is 
Option A is correct answer.
Step-by-step explanation:
We need to find simplified form of
Solving the given expression:
First we find factors of 
So, factors of are 
Now, fining the factors of 
So, factors of are 
Now the given expression will become:
Now, converting division sign into multiplication sign:
So, simplified form of is
Option A is correct answer.
Let's assign the width to a variable, with that variable being x. the length is two times the width, so it would be 2x. the perimeter of a rectangle is length + length + width + width, so you would add 2x + 2x + x + x = 24 inches. combine like terms (x) to get 6x = 24. divide both sides by 6 to get x = 4. so the width (x) is 4, and the length (2x) is 8. the area of a rectangle is length times width, so multiply 4 * 8. that would get you 32 inches^2.
The unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.
<h3>How to Find the Unit Rate of a Proportional Graph?</h3>
The unit rate of a proportional graph is determined using the formula below:
k = y/x, where x and y are coordinates of any point on the line.
Thus, to find the unit rate of a proportional graph, pick the coordinates of any point on the line and find k = y/x.
From the given graph, let's pick the indicated point on the line having the coordinates, (12,16). Find k:
Unit rate (k) = 16/12
Simplify
Unit rate (k) = 4/3
Therefore, the unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.
