Answer:
$3.85? 12/3.12 = $3.85
The answer would have came out of 3.84615384615
Then round up the answer to 3.85. So the unit price is $3.85.
The sum of the magnitudes will be the magnitude of the sum when the vectors have the same direction.
To solve this problem you must apply a theorem called: Intersecting secant theorem. The proccedure is shown below:
1) For the figure shown on the left:
(5)(x+5)=(6)(4+6)
5x+25=60
5x=60-25
x=35/5
x=7
2) For the figure shown on the right:
(3)(3+5)=(4)(x+4)
24=4x+16
24-16=4x
8=4x
8/4=x
x=2
The answer is in the question itself... so since it says 20 miles per hour that’s the distance it covers per hour. the answer would be it travels 20 miles in an hour
