Given:
The area of a rectangle = ![30m^{11}n^{5}](https://tex.z-dn.net/?f=30m%5E%7B11%7Dn%5E%7B5%7D)
Length of the rectangle = ![6m^4n^2](https://tex.z-dn.net/?f=6m%5E4n%5E2)
To find:
The width of the rectangle.
Solution:
Area of a rectangle is:
![A=l\times w](https://tex.z-dn.net/?f=A%3Dl%5Ctimes%20w)
Where, l is the length and w is the width of the rectangle.
Divide both sides by l.
![\dfrac{A}{l}=w](https://tex.z-dn.net/?f=%5Cdfrac%7BA%7D%7Bl%7D%3Dw)
![w=\dfrac{A}{l}](https://tex.z-dn.net/?f=w%3D%5Cdfrac%7BA%7D%7Bl%7D)
On substituting the given values, we get
![w=\dfrac{30m^{11}n^{5}}{6m^4n^2}](https://tex.z-dn.net/?f=w%3D%5Cdfrac%7B30m%5E%7B11%7Dn%5E%7B5%7D%7D%7B6m%5E4n%5E2%7D)
![[\because \dfrac{a^m}{a^n}=a^{m-n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5D)
![w=5m^{7}n^{3}](https://tex.z-dn.net/?f=w%3D5m%5E%7B7%7Dn%5E%7B3%7D)
Therefore, the correct option is A.
I think it is 395.20 / 5 = 79.04, rounded down to 79
Answer:
$132.25
Step-by-step explanation:
108.63 * 0.0375 ≈ 4.07
108.63 * 0.18 ≈ 19.55
19.55 + 4.07+ 108.63 = 132.25
Have a good day :)
Answer:
![p = -2](https://tex.z-dn.net/?f=p%20%3D%20-2)
Step-by-step explanation:
Create equivalent expressions in the equation that all have equal bases, then solve for p
.
Mistake found
3x-2(2x-4)=2
3x - 4x - 8 = 2 instead of 3x - 4x + 8 = 2
Correct answer
x= -13 y= -30
