The area of a triangle is one half the area of the parallelogram with the same base and height.
For a triangle, we have the formula
![A= \frac{1}{2}Bh](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7DBh)
.
For a parallelogram, we have
![A=Bh](https://tex.z-dn.net/?f=A%3DBh)
.
Answer: 9.7 seconds

Answer:
The expression is 100x + 50y ≤ 800.
Step-by-step explanation:
The hip hop DJ charge for $100 per hour. Let x be number of hours of hip hop :
![hip \: hop = 100 \times x](https://tex.z-dn.net/?f=hip%20%5C%3A%20hop%20%3D%20100%20%5Ctimes%20x)
![hip \: hop = 100x](https://tex.z-dn.net/?f=hip%20%5C%3A%20hop%20%3D%20100x)
For rap DJ, the charge is $50 per hour. Let y be the number of hours of rap :
![rap = 50 \times y](https://tex.z-dn.net/?f=rap%20%3D%20%2050%20%5Ctimes%20y)
![rap = 50y](https://tex.z-dn.net/?f=rap%20%3D%2050y)
Given that both DJs spend a maximum of $800. So the final expression is :
![100x + 50y \leqslant 800](https://tex.z-dn.net/?f=100x%20%2B%2050y%20%5Cleqslant%20800)
