Answer:
192
Step-by-step explanation:
The formula for the area of a rectangle is : 
In order to work out the volume you would first need to work out the area. You can do this by multiplying the length of 6 by the height of 4, this gives you 24.
To workout the volume you would need to multiply the area of 24 by the width of 8, this gives you 192.
1) Multiply 6 by 4.
2) Multiply 24 by 8.

Answer:
2nd friend heading west
Step-by-step explanation:
This is actually pretty easy to explain.
You and a friend are near a tree and decide to walk away from it. At the beggining you walked 15 yards and your friend too, and then, there's the turn of event. You walked 8 yards toward north east, and your friend 8 yards towards south west.
The key to know which is further from the tree is the angle of turning of both. We need to calculate the component in x from both persons, and then, add it to the previous 15 yards. This way we will know who is further.
Let's begin with the 1°, the one who's heading east:
X = 15 + 8 cos45° = 20.66 yards
Now the friend heading west:
X = 15 + 8 cos40° = 21.13 yards
With these results we can conclude that the 2nd friend is further from the tree.
Hope this helps
The answer is c. v=2.4r+154. v is the dependent variable, and r is the independent variable. From the equation above, if we increase r by 1 unit, v will increase by 2.4 (154 doesn't affect because it's always a constant). The unit of r is %, while the unit of v is thousand, therefore if we increase interest rate by 1%, the median house value increases by 2.4 thousand.
