Let's name Janet's age x
julie is then x-3 years old
and the brother is x-3-8=x-11
and all three of them: x+x-3+x-11 are 55
so we count:
2x-3+x-11=55
3x-3-11=55
3x-14=55
add 14 5o both sides:
3x=69
divide by 3:
x=23
so Janet is 23, Julie is 23-3=20 and the brother is 20-8=12 years old!
You should plot the total distance traveled from the base camp on the x-coordinate while the elevation should be plotted on the y-coordinate.
<h3>What is a graph?</h3>
A graph simply refers to a type of chart which is commonly used to graphically represent data on both the vertical and horizontal lines of a cartesian coordinate (x-coordinate and y-coordinate).
<h3>How to plot this graph?</h3>
In this scenario, you would plot the total distance traveled from the base camp on the x-coordinate while the elevation of the camps would be plotted on the y-coordinate as shown in the image attached below.

Answer:
25*pi or
78.5 square units.
Step-by-step explanation:
If there was no shaded area, the area of the circle would be pi * r^2
r = 10
Area = pi * 10^2
Area = 100 * pi
Since there is a shaded area, the shaded part looks to be 1/4 of the whole. There's no indication of what it actually is, but 1/4 should be close enough.
Area_shade = 1/4 (100*pi)
Area_shade = 25 * pi
That's one answer.
Another is 25 * 3.14 = 78.5 square units
