In order to make a fraction a ratio, you must simplify it if it is needed. So for 12/9, you can divide 3 from the numerator and denominator. That would equal 4/3. Now that it is simplified, you can make it into a ratio. (can be using ":" or using the word "to")
One way it can be used is --> 4:3
Another way --> 4 to 3
Good luck!
I believe that the answer is x=2.
No, she did not substitute the correct x and y values :)
Answer:
the third one
Step-by-step explanation:
First you need to calculate the circumference of the circle:
Circumference = diameter x PI = 16 x PI = 16 * 3.14 = 50.24
The intercepted arc is 15 degrees.
To find the length multiply the circumference by the central angle divided by 360.
Arc length = 50.25 x (15/360) = 2.1 units.
