Answer:
15 days
Step-by-step explanation:
Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.
In 1 day,
- A completes
of all work; - B completes
of all work.
Hence, in 1 day both A and B complete 
of all work. A and B working together can do a work in 6 days. Then
Solve this equation:
If 
then 
that is impossible. So, B needs 15 days to complete the work alone.
Answer:
I used the graph shown below.
Step-by-step explanation:
The equation of the line is y = x - 4
Inputs are the first number output is the second. So youre outputs are 2, -1, -1, and 3. so i would say b
Hello suga (jk), answer is C .20 cents!! You just divide 3 by 15.
<span>Assuming east is positive x, north is positive y, break down the airplane's velocity into a vector in the x-y plane.
The plane is traveling 340 mph at a bearing of 210 degrees or (340cos(210), 340 sin(210)).
The wind is blowing from the west (to the east) at 50 mph or (50,0).
The actual ground speed would be the vector sum of those two (340
cos(210)+50, 340 sin(210)) or (-294.4+50,-170) or (-244.4,-170).
The magnitude of that velocity vector is
For direction
Since this angle is measured from the (-y) axis, we add 180 to get the actual heading.
The plane is traveling at 297.8 mph at a heading of 214.8 degrees. </span>
