Write and solve an equation of ratios:
9 ft 22 ft
------- = -----------
h 99 ft
This is appropriate because h is greater than 9 ft.
cross-multiplying, we get
9(99) ft^2 = 22*h*ft
Then h =40.5 ft (which is the height of the building)
Answer:
![\left[\begin{array}{ccc}-32\\4\\20\\-36\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-32%5C%5C4%5C%5C20%5C%5C-36%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
The product of a scalar times the matrix involves the product of that scalar times each of the elements of the matrix, resulting on the multiplication by "-4" of each of the four elements as shown below. These new product values end up being the new matrix elements.
![-4*\left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right] = \left[\begin{array}{ccc}-32\\4\\20\\-36\end{array}\right]](https://tex.z-dn.net/?f=-4%2A%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D8%5C%5C-1%5C%5C-5%5C%5C9%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-32%5C%5C4%5C%5C20%5C%5C-36%5Cend%7Barray%7D%5Cright%5D)
Answer:
Mckayla 30%
Jacob 30%
Daniel 20%
Samantha 10%
Maria 10%
Step-by-step explanation: First Divide 20% into half to get samantha and marias percent then add those together then subtract what you get from that to 100% and then divide into half for Mckayla and Jacobs percent
