Answer:
The regular size is more economical.
Step-by-step explanation:
Consider the provided information.
A regular tube of toothpaste costs $2.50 for 3.2 ounces.
Find out the unit rate as shown below:

Therefore, the cost of one ounce is $0.78.
A travel size tube costs $1.00 for 1.2 ounces.
Find out the unit rate as shown below:

Therefore, the cost of one ounce is $0.833.
From the above calculation we can observe that regular tube toothpaste price is better buy.
Now find the percent as shown:
Firs find the difference
$0.83-$0.78 = $0.05
Therefore,

Hence, regular tube is 6.41% less costly as compare to travel size.
The answer to your question is <

Answer:

Step-by-step explanation:
The two things that are required to formulate the equation of the circle is the center coordinate and the radius of the circle!
<u>Center of the circle:</u>
- The center of the circle always lies at the midpoint of the endpoints of its diameter: Let's call the endpoints A(6,5) and B(8,5).
Using the midpoint formula we'll get:



This is the center coordinate of our circle.
<u>Radius: </u>
The radius of the circle is the distance from the center of the circle to any of the endpoints of the diameter (A or B)
We can use the distance formula:





<u>Equation of the circle: </u>
The equation is written as:

here, (a,b) are the center points of the circle
in our case this is 
and r = 1


This is the equation of the circle!
