To assess danger and trigger anti-predator behaviors
Answer: 8.5π
<u>Step-by-step explanation:</u>
If I understand the question correctly, the entire circle has an Area of 9π and you are looking for the Area of the shaded region which has a central angle of 
the section of the circle that is shaded is 
Area of the shaded region is: 
-25+4y=35
*Subtract 35*
-25+4y-35=0
*add 25 (to cancel out)*
4y-35=25
*add 35 (to cancel out)*
4y=60
*Divide by 4 to get y on its own*
y=15
Hope this helps :)
Hi there!
The replacement set is the set of values that may be subtituted for the variable. To find the solution set from the replacement set, you need to plug in each value frome the replacement set and evaluate both sides of the equation. If the two sides are equal, the equation is true and the value is a solution.
Here are the steps into solving this problem :
<em><u>Try 1 :</u></em>
7(0) - 3 = 18 ?
0 - 3 = 18 ?
-3 ≠ 18
<em><u>Try 2 :</u></em>
7(2) - 3 = 18 ?
14 - 3 = 18 ?
11 ≠ 18
<u><em>Try 3 :</em></u>
7(3) - 3 = 18 ?
21 - 3 = 18 ?
18 = 18
<u><em>Try 4 :</em></u>
7(4) - 3 = 18 ?
28 - 3 = 18 ?
25 ≠ 18
Your answer is : x = 3
There you go! I really hope this helped, if there's anything just let me know! :)
