Given :
A submarine started at the surface of the water and was moving at -15 meters per minute.
The submarine traveled at this rate for 48 minutes before coming to rest on the ocean floor.
To Find :
The change in the submarine position.
Solution :
We need to find the position of submarine position from the surface of water.
Distance travelled = Speed × Time
Distance travelled = -15 m/min × 48 min
Distance travelled = 720 m
Therefore, the position of submarine is 720 m below the surface of ocean.
Answer:
Basicallly, if the machine packs 2/3 of a box every 1/2 min, then the machine will pack twice as many boxes for 1 min, since 1/2 multiplied with 2 is 1.
2/3 multiplied with 2 is 4/3.
Therefore, the machine can pack 4/3 boxes per minute.

Answer: 
Step-by-step explanation:
The expression given in the exercise is:
If you descompose the number 8 into its prime factors, you get that:
Therefore, you can rewrite the numerator of the expression as following:
For this exercise you need to remember that for a Difference of cubes:
Then, applying this, you get:
Now, it is necessary to remember the following:
Knowing the above, you can say that:
Therefore applying this, you get that the simplified expression is:
Answer:
x = 2
Step-by-step explanation:
8x = 4x + 8
Subtract 4x from each side
8x-4x = 4x-4x + 8
4x = 8
Divide each side by 4
4x/4 = 8/4
x = 2
