Answer:
28.26 inches
Step-by-step explanation:
The circumference of a circle is, where d = diameter. In this case, we use pi as 3.14 and the diameter as 9.
Therefore, the answer is 28.26.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
x= - 30
Step-by-step explanation:
x-9=0.7x+0.6
x-9=1.3x
x-9-1.3x=0
x-1.3x=9
x(1-1.3)=9
-0.3x=9
x= - 9/0.3
x= - 30
Answer:
a, c, b, a
Step-by-step explanation:
We are not given a specific group that was surveyed, so all we would do is add all the students.
32 + 23 + 31 + 12 + 8 + 30 + 11 = 154
We end up with 154 students that were surveyed.

Answer:
A=2.5
B=2
Step-by-step explanation:
A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.
We can compare the two sides using algebra.
4b+7=8b-1
Using simple methods, we can isolate b on a single side.
1+7=8b-4b
8=4b
b=2
From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.
2a = 2b+1
2a = 2(2)+1
2a=4+1
2a=5
a=2.5
