Answer:
-1.25
Step-by-step explanation:
The difference between the y values is -5, and the difference between the x values is 4.
-5/4 = -1.25
Make a proportion the sales tax is a percent of the total purchase and you just have to figure that out. 1,200/100=72/x solving this i get 6% sales tax using that. I find the rest by taking 6% of 2500 =150. And for part b make another proprtion x/100=108/6. And i get 1800 dollars
Option C is correct.
Step-by-step explanation:
We need to identify the composite numbers from the given options
<u>Composite Numbers</u>
A number is composite number if it has factors other than 1 and the number itself i.e the number is not prime.
The numbers 19, 23 and 37 are prime numbers because they have factors 1 and the number itself while 33 is composite number because it has factors 1,3,11,33.
So, Option C is correct.

Step One
Develop a formula for the perimeter.
Argument
What you see is a semicircle going upwards and another one going downwards. Two semicircles =1 circle.
The "perimeter" [Circumfrence] of a whole circle = 2*pi*r
We are told that whatever you call this the perimeter is 8pi + 16
Step Two
Set up the equation
8pi + 16 = 2*pi*r + 4r Including the line connecting these two.
Step Three
Take out the common factors on the left and right.
8(pi + 2) = 2r(pi + 2) Divide both sides by pi + 2
8 = 2r Divide by 2
4 = r
Sorry. I didn't know the meaning of perimeter. Mathmate is perfectly correct.
