Answer:
circumference of circle=2πr=2×3.14×3.5=21.98=22
Answer:
The graph is a solid line, and the shading is above the line.
Step-by-step explanation:
Given
Required
Describe the graph of the inequality
We have:
Subtract x from both sides
The sign 
implies that the graph has a solid line
The sign which means greater than or greater also implies that the upper region is shaded
No, (2 , 3) does not satisfy the inequality 4x + 3y > 20.

2 angles whose sum is 180 are supplementary angles
The answer is 1/20. This is probability. <u><em>probability is the chance of you picking a certain thing</em></u>. for example: You have 3 blue marbles, 6 red marbles, and 4 purple marbles. the probability of pick a blue marble is 3/13. A red would be 6/13, and a purple would be 4/13.
So what this is asking is what are the chances that something will happen over something will not happen. the said that "the probability that an event will not happen is P(E') = 19/20. if you are having a lot of trouble with this, try removing the events with something like marbles (Something you have done before) this tends to make it a little easier to read.
