Answer:
Speed of Chris Huber = 30.726 m/s
Time taken by Sam = 5.55 s
Step-by-step explanation:
Given:
Distance = 200 m
Time taken by Chris Huber = 6.509 s
Now,
Speed of Chris Huber = 
or
Speed of Chris Huber = 
or
Speed of Chris Huber = 30.726 m/s
Speed of Sam = Speed of Chris Huber + 19.0 km/h
Now,
1 km/hr = 0.277778 m/s
thus,
19.0 km/h = 19.0 × 0.27 = 5.278 m/s
thus,
Speed of Sam = 30.726 + 5.278 = 36.004 m/s
therefore,
Time taken by Sam = 
or
Time taken by Sam =
= 5.55 s
The answer is the last one. D
V+8*v-3
v+v=2v
8+-3=5
Equation would be: 2v*5 because you cannot combine unlike terms
we know that
The measure of the interior angle is the half sum of the arcs comprising it and its opposite
so
m∠CED=
see the attached figure with letters to better understand the problem
° ------> by central angle
° ------> by central angle
Substitute the values in the formula above
m∠CED=
m∠CED=
m∠CED=
°
therefore
<u>the answer is</u>
m∠CED=
°
