The answer is
t=tuesd=5km
w=wednes=6.2km
T=Thurs=50m=0.05km
the total during those three days are= t+w+T=11.25km
P= k/Q
16.4= k/123
k= 16.4 * 123
k= 2017.2
Therefore, P= 2017.2/Q
Answer:
15.4
Step-by-step explanation:
98×2.2÷14 = 215.6 = 15.4
Step-by-step explanation:
Inflection points are where a function changes concavity (the second derivative changes signs). At x = 4, f"(x) goes from negative to positive, so that's an inflection point. However, at x = 8, we don't know if f"(x) changes signs or not. So we can't say that that's an inflection point.

Answer:
150°
Step-by-step explanation:
The rule here is that the external angle is half the difference of the arcs subtended. That relation is used to form an equation, which can then be solved for whatever measure is of interest.
(RB -EC)/2 = D
((13x +7) -(60))/2 = (5x -10)
13x -53 = 10x -20 . . . . . . . . . . multiply by 2
3x = 33 . . . . . . . . . . . . . . add 53-10x to both sides
x = 11 . . . . . . . . . . . . divide by 3
RB = 13x +7 = 13·11 +7 = 150
The measure of arc RB is 150°.
