Answer:42
Step-by-step explanation:
11+8=19+11=30+12=42
Answer:
Let d = the one-way trip
Write a time equation: time = dist/speed
time out + time back = 4.5 hrs
d/80 + d/100 = 4.5
Multiply by 400 to clear the denominators
400*d/80 + 400*d/100 = 400(4.5)
Cancel the denominators
5d + 4d = 1800
d = 1800/9
d = 200 miles max distance
Answer:
A) √((distance travelled due north)²+(distance travelled due east)²)
B) distance from starting point
C) Yes due west
Step-by-step explanation:
A) According to pythagoras theorem
resultant vector= √((distance travelled due north)²+(distance travelled due east)²)
Also see 1st attachment
B) The resultant vector tells the distance from the starting point
C) The same amount of distance travelled in opposite direction that is westwards will give same magnitude of resutlant vector.
See 2nd attachment
Answer:
the value of x is 1......
as we know B is the midpoint....
then,
5x-7=3x-5
5x-3x=-5+7
2x=2
x=2/2
x=1
