All you do is add them all together...
20 + 11.4 + 11.4 + 4.5 + 4.5 + 0.45 + 0.45 + 0.45 + 0.45 = 53.6Kg
(note that 0.45 is 450g in Kg, When adding things such as weight or length you want to make sure that they are all in the same unit)

A plane, initially traveling 150 mi./hr. 100 east of north, suddenly enters a region where the wind is blowing at 50 mi./hr. fro

Leona [35]

Answer:

the Velocity of the plane is 100 mi/hr along the northeast direction

Step-by-step explanation:

According to the Question,

Given That, the Initial velocity of the plane is 150 mi/hr along the east north direction and the wind is blowing at 50 mi/hr along the southwest direction

since the velocity of wind and plane is exactly opposite

the relative velocity of the plane with respect to the wind is given by

$V_{r} = V_{p} -V_{w}$ , where $V_{p}$ is the velocity of plane = 150mi/hr and $V_{w}$ = velocity of wind = 50 mi/hr

Therefore, Relative Velocity = 150-50 ⇒ 100mi/hr along northeast direction

Thus, the velocity of the plane is 100 mi/hr along the northeast direction

The improper fraction 8/5 is equivalent to

olga2289 [7]

8/5

We have to just divide.

Here 1 is the quotient while 3 is the remainder when 8 is divided by 5.

So, 8/5 is also equal to 1 3/5.

Hope This Helps You!
