Answer:45.66
Step-by-step explanation: Simplify the expression.
Hope this helps you out! ☺
The second person must be 20 years old, since that is the median of the ages.
If the mean is 22 years, then the sum when all three added together is 66.
That means, the youngest and the oldest add up to 46 years old.
Let the oldest be x + 16, then the youngest must be x.
x + 16 + x = 46
2x + 16 = 46
2x = 30
x = 15
Since the youngest person is 15, the oldest must be 31.
Hence, the ages, from youngest to oldest, are: 15, 20, 31
What I would do first is find the base and height of the rectangle and from there you have the diameter of the circle so you can divide that by 2 and you have your radius which you’d be able to find the total area
Answer:
1040
Step-by-step explanation:
Circumference of the Circle: 439.82
Add that to the length of the rectangle time two: 439.82+(300x2)
That will give you the perimeter around the entire track:
439.82+(300x2)
439.82+600
1039.82
Rounded that is: 1040

Answer:
PQ = √(7-2)²+(3-5)²
= √ 5²+(-2)²
= √ 25+4
=√29 units
