Answer:
Distance Jamie must sprint to reach Shelly is; L = 107 m
Step-by-step explanation:
We are given;
Central angle;θ = 123°
Radius;r = 50m
Now, for us to find out how many meters Jamie must sprint to reach Shelly, we'll use the formula for arc length of a circle;
Arc length; L = 2πr(θ/360)
So, plugging in the relevant values, we have;
L = 2π(50)(123/360)
L = 107.34 ≈ 107 m
L = 107 m
Answer:light
Step-by-step explanation:The independent variable is the condition that you change in an experiment. It is the variable you control. It is called independent because its value does not depend on and is not affected by the state of any other variable in the experiment.
It would be 10 because the factors add up and it makes sense
