Answer:
Here are the steps to find the volume.
Step-by-step explanation:
- Volume = length x width x height.
- You only need to know one side to figure out the volume of a cube.
- The units of measure for volume are cubic units.
- Volume is in three-dimensions.
- You can multiply the sides in any order.
- Which side you call length, width, or height doesn't matter.
As we know, sum of interior angles of a triangle is 180°
that is ~
Hence, value of x is 9°
Answer:
10.8 inches
Step-by-step explanation:
72/20=3.6
3.6*3=10.8
The value of x is 1/13 (4th choice)
Step-by-step explanation:
![{a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} }](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%20%3D%20%20%5Csqrt%5Bn%5D%7B%20%7Ba%7D%5E%7Bm%7D%20%7D%20)
If 14^x = ¹³√14, what value of <em>x </em>makes this equation true?
![\sqrt[13]{14} = {14}^{x} \\ \sqrt[13]{14} = {14}^{ \frac{1}{13} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B13%5D%7B14%7D%20%20%3D%20%20%7B14%7D%5E%7Bx%7D%20%20%5C%5C%20%20%5Csqrt%5B13%5D%7B14%7D%20%20%3D%20%20%7B14%7D%5E%7B%20%5Cfrac%7B1%7D%7B13%7D%20%7D%20)
So, the value of <em>x</em> is 1/13 (4th choice)
