Answer:
67519.7 Feet per minute
Step-by-step explanation:
343 metres per second = 67519.7 feet per minute.
Just plug in your x and solve like normal
-4< 4(1) - 8 < 12
-4< -4 < 12
now solve both sides by moving the -4 out by adding + 4 to all sides
0 < x < 16
when read this says 0 is less than X and X is less than positive 16.
the other 3 are solved the same.
Here is how you would do this: If there are 1000 meters in one kilometer, and you know that this track is 200 meters long, then you can find how many times Julius must run around the track in order to reach ONE kilometer:
1000 meters / 200 meters = 5 times in around the track for ONE kilometer.
To find how many times Julius would need to run around to reach THREE kilometers you simply do the following:
5 x 3 = 15 ---> Julius would need to run around the track 15 times in order to reach 3 kilometers.
The correct answer is D. 
Explanation:
The surface area refers to the sum of the area of all sides in a 3D shape such as a cube or cylinder. Additionally, the formula used to calculate the surface area varies with the shape. In the case of cylinders, the general formula is 
. Moreover in this, the r represents the radius (measure from the center of a circle to any side), while the h represents height. Below, all the process is shown:
In this point, you have the answer without solving 
(3.1416). This makes option A the correct answer.
