Answer:
2 1/4
Step-by-step explanation:
To figure out how many pounds of jellybeans Betty has you need to subtract 6 and 3 3/4.
To subtract you need to turn 6 into a fraction by putting a 1 under it so it becomes 6/1
Then turn 3 3/4 into an improper fraction by multiply 3 by 4 which equals 12, then adding 3, so its 15/4.
Now subtract 6/1 by 15/4 but first multiply 1 by 4 and then multiply 6 by 4 so that the denominators are the same.
So now its 24/4 - 15/4
Now subtract across, which equals 9/4
This can be changed into a mixed number 2 1/4
For this case we have that by definition, the general equation of the circle is given by:
Where,
- <em>(h, k): it is the center of the circle
</em>
- <em>r: radius of the circle
</em>
We then have the following equation:
Comparing values we have:
For the center of the circle
:
For the radius:
Then, the diameter is given by:
Answer:
Johnny is wrong:
The center of the circle is (11, -15)
Joyce is wrong:
The diameter of the circle is 24
C. 212 degrees Fahrenheit
Answer:
