C. 17 r 1 is the correct answer
Answer: 350 adult tickets
Step-by-step explanation:
(omg I remember this question!)
- a stands for the number of adult tickets sold
student tickets : a + 65
<em>the equation for the prob: </em>
765 = a + (a + 65)
<em>solve:</em>
combine 'like terms'
1.) 765 = a + a + 65
2.) 765 = 2a + 65
<u>- 65 - 65 </u>
700= 2a
divide by 2
700/2 = 2a/2
<em>(700/2 = 350) </em>
<em>(the "2" in 2a is cancelled out by the other 2)</em>
<u>350 = a </u>
It is: i √6 i believe :))
Here is my notes from 7th grade math class!
Answer:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Step-by-step explanation:
Given that circumference of circle is: 
The formula for circumference of circle is:

Comparing both formulas, we get

The radius is obtained by dividing 24 by 2.
We also know that the area of circle is:

The radius is being squared and then multiplied by pi to get the area.
Hence,
The correct answer is:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
