Answer:
82
Step-by-step explanation:
We are given that a graph which shows the number of beads used for varying cord lengths.
The graph
We have to find the number of beads that she can used for cord length 32 in.
Substitute the value x=32
Then, we get
After round to unit place then, we get
y=82
Hence, the best estimate she can used for number of beads =82
Answer: 82

Answer:
m∠2 = 140°
Step-by-step explanation:
m∠1 = m∠3, since they're vertical angles.
Solve for x:
Plug in 6 for x for either m∠1 or m∠3. Doesn't matter since they're equal.
m∠1 = (2(6) + 28)°
m∠1 = (12 + 28)°
m∠1 = 40°
Now that we know m∠1, we can now solve for m∠2.
m∠1 + m∠2 = 180°
40° + m∠2 = 180°
m∠2 = 140°
My favorite strategy is the criss cross method. 
Take the numerator of the first fraction (2), and the denominator of the second fraction (8) and multiply them. The value 16 is now up on the left side, imaginary. (ALWAYS PUT THE PRODUCT ON THE SIDE WITH THE NUMERATOR) Now multiply the other diagonal. 3(7)=21. The 21 is on the right side. Now do 16 ? 21
Is it <, >, or =? The answer is <
