Answer:
You and your friend are about 2.09 miles apart after 15 minutes.
Step-by-step explanation:
To find your distance apart, you can convert 15 minutes to seconds because that is what the rate is given in.
15 mins x 60 seconds = 900 seconds.
In 900 seconds, there are 900/8=112.5 groups of 8 seconds. This means there are 112.5 groups of 108 feet.
112.5 x 108 = 12150 feet
12150 feet/5280 feet is approximately 2.3 miles.
For your friend you take 900/6 = 150 groups of 6 seconds.
150 x 63 = 9540 feet
9540 feet/5280 feet = 1.79 miles
1.79 miles + 2.3 miles = 2.09 miles
You and your friend are about 2.09 miles apart after 15 minutes.

Answer:
y = -1
Step-by-step explanation:
It´s an equilateral triangle
then:
2y + 6 = 4
2y = 4 - 6
2y = -2
y = -2/2
y = -1
Check:
2*-1 + 6 = 4
-2 + 6 = 4
Answer:
7. 30° 8. 97.5° 9. 90° 10. 55° 11. 100° 12. x=32° y=64°
(-30 km/h) -(45 km/h) = -75 km/h . . . . . east is positive here
The velocity changed 75 km/h to the west.
