Answer:
I think its 226800.
Step-by-step explanation:
8% of 210,000 is 16800. I added that to 210,000 and got my answer.
Let the distance of the first part of the race be x, and that of the second part, 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5
Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutes
The distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.
Answer:

Step-by-step explanation:
Line q will be graphed on the same grid. The only solution to the system of linear equations formed by lines n and q occurs when x =
and y = 0.
Now, as x =
is a solution of the equation, y = f(x) = 0, so,
will be a factor of the linear function y = f(x).
Therefore, we can write the possible equation for the line q will be
. (Where k is any constant} (Answer)
The distance the tip travels is
2π·(40 m) = 80π m
Then its speed is
(80π m)/(10 s) = 8π m/2 ≈ 25.1 m/s
