Answer and Step-by-step explanation:
So to figure out the Sales tax column, you make the percentage into a decimal. 7.25% into 0.0725
Then multiply 0.0725 by the cost of the item to get the sales tax. For example, 0.0725 * 8 = 0.58

Answer: No they don't because there is not way 1/3 can be multiplied by a number to get 2/9 and there is no way 2/9 can be divide by any number to get 1/3.

Answer:
The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π = 
⇒ answer C
Step-by-step explanation:
In any circle there is a constant ratio between the circumference of the circle and its diameter
This constant ratio is called π
∵ The formula of the circumference of a circle is C = π d,
where d is the diameter of the circle
- Divide both sides by d
∴ 
= π
- Switch the two sides
∴ π =
∵ The diameter of the circle is 5 centimeters
∴ π =
The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =

$514 give or take. I could be wrong so you might want some confirmation on my answer before putting it on your test or what ever you need it for because i'm only in Middle School.
Step-by-step explanation:
Answer:
Graph #1 - y=-20x+40
Graph #2 - y=5x+10
Step-by-step explanation: The first thing that you do is pull two points from each of the graphs and find the slope. To find the slope you use
<h2>
M = y2-y1/x2-x1</h2>
<u>FROM GRAPH #1:</u>
<h3>(3,40) (2,80)</h3>
(x1,y1) (x2,y2)
80-40/2-3
20/-1
M = -20
<u>FROM GRAPH #2:</u>
<h3>
(1,10) (3,20)</h3>
(x1,y1) (x2,y2)
20-10/3-1
10/2
M = 5
2. Now once you find the slope you will use the equation of a line formula to form an equation.
<h2>
y=mx+b</h2>
The (mx) is your slope, the (b) is the y-intercept. (any value on the y-axis)
3. Since we now know the equation of a line and the slope we will substitute the variables.
<u>Graph #1:</u>
y=mx+b
y=-20x+40
<u>Graph #2:</u>
y=mx+b
y=5x+10
