Answer:
20%
Step-by-step explanation:
To find the percent decrease, we do old number subtracted from the new numbers over old.
We do
40 - 32 = 8
Then we put the 8 over the old and get
8/40
In percentage form it would be 20%

Answer:
Choice B is correct
Step-by-step explanation:
The given radical division can be expressed in the following form;
![\frac{\sqrt{16x^{3} } }{\sqrt{8x} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B16x%5E%7B3%7D%20%7D%20%7D%7B%5Csqrt%7B8x%7D%20%7D)
Using the properties of radical division, the expression can be expressed in the following form;
![\sqrt{\frac{16x^{3} }{8x} }=\sqrt{2x^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B16x%5E%7B3%7D%20%7D%7B8x%7D%20%7D%3D%5Csqrt%7B2x%5E%7B2%7D%20%7D)
Simplifying further yields;
![\sqrt{2x^{2} }=\sqrt{2}*\sqrt{x^{2} }=x\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2x%5E%7B2%7D%20%7D%3D%5Csqrt%7B2%7D%2A%5Csqrt%7Bx%5E%7B2%7D%20%7D%3Dx%5Csqrt%7B2%7D)
Choice B is thus the correct alternative
Answer:
1000 square feet.
Step-by-step explanation:
to find the area, you multiply the length by the width
40*25=1000
