Answer:
Distance from the airport = 894.43 km
Step-by-step explanation:
Displacement and Velocity
The velocity of an object assumed as constant in time can be computed as
Where 
is the displacement. Both the velocity and displacement are vectors. The displacement can be computed from the above relation as
The plane goes at 400 Km/h on a course of 120° for 2 hours. We can compute the components of the velocity as
The displacement of the plane in 2 hours is
Now the plane keeps the same speed but now its course is 210° for 1 hour. The components of the velocity are
The displacement in 1 hour is
The total displacement is the vector sum of both
The distance from the airport is the module of the displacement:
Answer:
12
Step-by-step explanation:
6 * x = 72
x = 72 / 6
x = 12
The formula for the volume of a sphere is V = (4/3) * π * r³. Knowing this, we can plug in the radius:
The sphere's volume is approximately 2144.66 mm^3.
<span>Total mass of mixture is given as 5/6 pound, in which 1/4 pound is gravel. Amount of sand in the mixture will be 5/6 - 1/4 = 7/12
So, the ratio of sand to that of gravel in given mixture is 7/12:1/4 = 7:3. i.e every 10
parts of mixture contain 7 parts of sand and 3 parts of gravel.
If we are given 1-pound of same mixture, it will contain 1 * 3/10 pound gravel, i.e. 0.3 pound.</span>
Answer:
213 or 213.68 or 214
Step-by-step explanation:
5342 divided by 25 it is 213.68 rounded it would be 214 but its only asking for the full boxes so it may be 213
