Answer: 6
Step-by-step explanation:
The slope of ST is
The slope of UV is
Since parallel segments have the same slope,
A + 4(a - 5) = 5
a + 4a - 20 = 5
5a = 5 + 20
5a = 25
a = 25/5
a = 5 <====
Answer:
4
Step-by-step explanation:
Plane A 520 feet vertical rise 40 feet/min
plane B 3800 feet vertical dip 120 feet per minute.
vertically the speeds are 40 feet / minute & 120 feet /minute.
120 + 40 = 160 feet per minute.
the distance between them = 3800 -520 =3280 feet
t= d/r
3280/160
t = 20.5 minutes. they will be at the same altitude.
