Answer:
120 miles in 4.8 hours
75 miles in 5 hours
Step-by-step explanation:
Ship:
The number f(x) of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 120 - 25x. This means, initially the ship is 120 miles away from its destination.
If the ship traveled 120 miles, then f(x)=0 (the ship will be 0 miles away from its destination) and
0 = 120 - 25x
25x = 120
x = 4.8 hours.
Submarine:
At x = 0 hours the submarine was 75 miles away
At x = 5 hours, the submarine was 0 miles away.
So, in 5 hours the submarine traveled 75 miles
Answer:
1,560$
Step-by-step explanation:
200 on first 5000$
400 on second 5000$
960 on remaining 8000$
= 1560 total
The answer is x=6.
Hope this helps.
Answer:
Angle 1 = 119 degrees.
Step-by-step explanation:
3x + 31 = 6x + 1 (exterior alternate angles)
30 = 3x
x = 10
So the angle marked 6x + 1 = 6(10)+1
= 61
Angle 1 is adjacent to this so it is 180-61 = 119 degrees.
