Answer
Because velocity and speed differ each other by direction, in a 100 m sprint race the person moves in a straight path without changing its direction where as in a 400 m race. The person moves in a lap around the race track and the direction changes as he turns according to the race track.
Step-by-step explanation:

Answer:
t ≤ 225r
Step-by-step explanation:
Distance = 225 miles
Time taken = t
Average speed = r miles per hour
Recall :
Speed = distance / time
Time, = distance / speed
t = 225 miles / r
All possible values of t :
t ≤ 225r
Answer:
Step-by-step explanation:
Note that the squares are on the sides of these triangles are on the hypotenuse/one leg.
We know that the area of a square is 
where l is the length. Since we know the area, we can find the square root of the area to find the side length.
So the side lengths are 
and 
.
Since we know the hypotenuse is and one of the legs is , we can use the Pythagorean Theorem to find the missing side.
The Pythagorean Theorem states that 
, where c is the hypotenuse and a/b are the legs.
We know the <em>hypotenuse </em>and <em>a leg</em>, so we can substitute inside
Squaring a square root is the same as doing nothing.

Answer:
23/55
Step-by-step explanation:
Assuming you want this simplified,
23/55
Answer:
The correct answer is C.
Step-by-step explanation:
In order to find the line, we first need to find the slope. For that we use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-12 - 3)/(-1 - 2)
m = -15/-3
m = 5
Now we put the slope and one of the points into point-slope form and solve for y.
y - y1 = m(x - x1)
y - 3 = 5(x - 2)
y - 3 = 5x - 10
y = 5x - 7
