I'm not sure if you need the answer or just the steps to start, so I will just give u the steps. First, just take a step back and take it one step at a time. Once you have an idea of how the two triangles are congruent, make 2 columns, one with statements and one with reasons. On the statements side, put given information and what you learn along the way, like if it is given x=y, and y=z, then what you can put down after that is x=z. On the reasons side, put the properties or formulas you used to reach your solution. For instance, if x=y and y=z, x=z by the Transitive property of equality. Proofs are time consuming, tedious and utterly frustrating. Just take it slowly and you will be fine.
Answer:
They are the same
Step-by-step explanation:
One hundred draws are made at random.
The average of a list of numbers equals the sum of the numbers divided by how many numbers there are.
So, when the sum of the 100 draws is 710, the average of the draws will be
710/100 = 7.1
So, when the sum of the draws is bigger than 710, the average of the draws will be bigger than 7.1.
Therefore, the two chances are the same.
Well one way is to decide if its a right triangle, if so the right angle will always be 90 degrees
Answer:
2√(5/π) ≈ 2.523
Step-by-step explanation:
The radius can be found using the area formula:
A = πr²
20 = πr² . . . . . fill in the given value
20/π = r² . . . . . divide by π
√(20/π) = r = 2√(5/π) . . . take the square root and simplify
You can use your calculator to find a numerical value for this:
r = 2√(5/π) ≈ 2.52313

<em>Comment on the form of the answer</em>
Radicals are often considered to be in simplest form when they do not contain fractions or square factors. Here, the "simpler" form would be ...
r = (2/π)√(5π)
involving the irrational number π in two calculations. My preference for evaluating the expression for r is to leave it as √(20/π) or 2√(5/π).
