Answer:
(Approximation to the nearest thousandth)
Step-by-step explanation:
The area of a cylinder can be determined by the formula:
(We know that the radius, r, is 2m, and the height, h, is 5m, so we can substitute them into the formula to calculate the volume of this cylindrical tank)
(Simplify)
(Approximation to the nearest thousandth)
Lol. ..I just finished this one for another person
2 (n-2) = n - 5/2
Answer: Second option.
Step-by-step explanation:
As you can observe in the picture given in the exercise, there are two Right triangles formed inside the rectangle: CDA and ABC.
You need to use the Pythagorean Theorem to solve this exercise. This is:
Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.
If you solve for one of the legs, you get the following equation:
In this case, you can identify in the figure that:
Finally, you must substitute these known values into the equation and then evaluate in order to find the value of "x". You get that this is:
