Hey there! :)
Answer:
arc AB = 2.5π in (in terms of pi) or ≈7.85 in. (pi = 3.14)
Step-by-step explanation:
Begin by finding the circumference of the circle. Use the formula:
C = 2rπ
C = 2(9)π
C = 18π.
Since ∠AQB equals 50°, set up a ratio to find the length of arc AB:
Cross multiply:
50 · 18π = 360x
900π = 360x
Divide both sides by 360:
x = 2.5π in, or ≈7.85 in.
By creating a common denominator, you can compare different numbers to the same ratio. For example:
Take 2/3 and 3/4
Now 3/4 is the same as 9/12
And 2/3 is the same as 8/12
Now that they have the same denominator, you can tell that 9/12 is clearly greater than 8/12, meaning 3/4 is greater than 2/3.
8x-12=36
Let's solve your equation step-by-step.
<span><span><span>8x</span>−12</span>=36
</span>Step 1: Add 12 to both sides.
<span><span><span><span>8x</span>−12</span>+12</span>=<span>36+12
</span></span><span><span>8x</span>=48
</span>Step 2: Divide both sides by 8.
<span><span><span>8x/</span>8</span>=<span>48/8
</span></span><span>x=6
</span>Answer: x=6

Answer:
The sixteen people to March in the sportsmanship parade
Step-by-step explanation:
A sample refers to a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population.
A sample should represent the population as a whole and not reflect any bias toward a specific attribute.
Since the coach chose 16 people to March in the sportsmanship parade, the sample in this situation, The sixteen people to March in the sportsmanship parade is the sample
