If you haven't,a good thing to do with negatives is to look at a number line at least once to help see the picture. For this example, you could say that 0 is sea level. Let's say there's a fish 6 feet below sea level. Since it's below, it's be -6 feet.
Answer: <em>15</em>
Step-by-step explanation:
<em>8x-60°</em>
<em>8(15)-60°</em>
<em>120°-60°</em>
<em>60°</em>
<em />
X WILL EQUAL 15 BECAUSE 120 - 60 WILL EQUAL 60!
THE TRIANGLE MUST ADD UP TO 180°!!
You order the numbers from lowest to highest and the middle number is the median. If there’s an even amount, you add the two middle numbers and divide by two.
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).
