a vehicle travels 24km with a constant speed of 65 km/h and another 50 km with a constant speed of 80 km/h what was its average speed

Answers

Answer 1

Answer: average speed=totaldistance/totaltime

totaldistance=24+50=74km

total time
65/24=0.3692307 hours

80/50=1.6 hours
total time=0.3692307+1.6=1.9692307

averagespeed=74/1.9692307=37.5781263 km/h

8n + 2 = 5n + 11 , does anyone one know the answers

Answers

Answer:

n=3

Step-by-step explanation:

8n + 2 = 5n + 11

Subtract 5n from each side

8n-5n + 2 = 5n-5n + 11

3n+2 = 11

Subtract 2 from each side

3n+2-2 = 11-2

3n = 9

Divide by 3

3n/3 = 9/3

n =3

Answer:

n=3

Step-by-step explanation:

Let's do the algebra step-by-step.

8n+2=5n+11

-2 -2

8n=5n+9

-5n -5n

3n=9

Question 1 (1 point)Find the coordinates of point P that divides the directed line segment from A to B in the given ratio. A(1, 2), B(5, 4), 1 to 1

Answers

Answer:

P ( -1, -3)

Step-by-step explanation:

Given ratio is AP : PB = 3 : 2 = m : n and points A(5,6) B(-5,-9)

We will calculate coordinates of the point P which divides line segment AB in the following way:

xp = (n · xa + m · xb) / (m+n) = (2 · 5 + 3 · (-5)) / (3+2) = (10-15) / 5 = -5/5 = -1

xp = -1

yp = (n · ya + m · yb) / (m+n) = (2 · 6 + 3 · (-9)) / (3+2) = (12-27) / 5 = -15/5 = -3

yp = -3

Point P( -1, -3)
