Answer:
![(\frac{a^{2}b^{-3} }{a^{-2}b^{2} })^{2} = (a^{2-(-2) }b^{-3 - 2})^{2} \\ = (a^{4}b^{-5} )^{2} = (a^{4})^{2} (b^{-5})^{2} = a^{8} b^{-10}](https://tex.z-dn.net/?f=%28%5Cfrac%7Ba%5E%7B2%7Db%5E%7B-3%7D%20%20%7D%7Ba%5E%7B-2%7Db%5E%7B2%7D%20%20%7D%29%5E%7B2%7D%20%20%3D%20%28a%5E%7B2-%28-2%29%20%7Db%5E%7B-3%20-%202%7D%29%5E%7B2%7D%20%5C%5C%20%3D%20%28a%5E%7B4%7Db%5E%7B-5%7D%20%29%5E%7B2%7D%20%20%3D%20%28a%5E%7B4%7D%29%5E%7B2%7D%20%28b%5E%7B-5%7D%29%5E%7B2%7D%20%20%3D%20a%5E%7B8%7D%20%20b%5E%7B-10%7D)
Here is for you.
Step-by-step explanation:
Answer:
18%
Step-by-step explanation:
Since the original price is $78 then this is the original 100% of the price. The new price will be marked up x percent and be $92. To find the new price set up a proportion with these values:
![\frac{92}{78}=\frac{x}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B92%7D%7B78%7D%3D%5Cfrac%7Bx%7D%7B100%7D)
Solve for the original price by cross multiplying numerator with denominator.
x(78) = 92(100)
78x = 9200
x= 117.9 = 118%
This is 18% more or over the original price.
Answer:
See below.
Step-by-step explanation:
1. The opposite sides of a parallelogram and a rectangle are equal.
All angles in a rectangle are right angles. A parallelogram has 2 pairs of opposite equal angles, the angles are not necessarily right angles.
A rectangle is a special form of a parallelogram.
