Answer:
Step-by-step explanation:
He traveled at 60 mph a distance of 60*hours.
He traveled at 40 mph the same distance of 40(15 hrs - time hrs). The distance is the same; therefore, set them equal.
60t = 40(15-t)
60t = 600 - 40t
100t = 600
t = 6 hrs for the 60 mph day.
15-t = 9 hours for the 40 mph day.
distance = 6 h x 60 mph = 360 miles.
distance = 9 h x 40 mph = 360 miles.
The perimeter = 2 length + 2 width
the length = the width +47
314 = 2*(w+47) +2w
314 = 2w +94 +2w
220 =4w
w= 220/4 = 55
l = 55+47 = 102
the length = 102 ft
the width = 55 ft

Answer: the answer is a
Step-by-step explanation:
<span>The sinusoidal curves are shown in the picture attached.
Note that the two waves have the same amplitude (same "height"), the same wavelength (same distance from one peak to the next one) and therefore the same frequency, but different phase (they start in different points).
When you sum two different sinusoidal curves with the same amplitude and frequency, but different phase you get a sinusoidal wave with the same frequency as the original curves, but a different amplitude and a different phase.
Therefore, the correct answer is
graph B).
