Answer:
Circle B has a larger circumference.
Step-by-step explanation:
Circumference of a circle is the diameter times pi.
C = pi•d
Circle B has radius 5, so its diameter is 10. Circle A has diameter of 9. A larger diameter will give a larger circumference.
C_circle A = 9pi
~= 28
While,
C_circle B = 10pi
~= 31
Circle B's circumference is about 3 cm larger. More accurately it's 1pi larger.

Find the percent of students in her class that have a dog or cat:
- Set up a proportion:
- Cross multiply, then divide: 18 × 100 = 1800, 1800 ÷ 30 = 60
- So, 60% have a dog or cat
Find 60% of the total amount of students in Monique's school:
- 60% of 870 =
× 
- ×

The solution has to be a value of x. Since you already have x, you just have to plug in the value and see what fits. In this case thats the third from the top:
5^2 - 10*5 + 25 = 0
25 - 50 + 25 = 0
0 = 0
Hope it helps!
