Answer:
Adult ticket is $7.5 while a child's ticket is $11
Step-by-step explanation:
Given data
Let the cost of an adult ticket be x
and the cost of a child ticket be y
The Seward family
2x+3y= 44.50---------1
The Sena family
3x+6y= 78-------------2
solve 1 and 2
2x+3y= 44.50 X2
3x+6y= 78 X1
4x+6y= 89
- 3x+6y= 78
x+ 0= 11
x= 11
put x= 11 in 1
2x+3y= 44.50
2*11+3y= 44.5
22+3y=44.5
3y= 44.5-22
3y= 22.5
y= 22.5/3
y= 7.5
Hence Adult ticket is $7.5 while a child's ticket is $11
Answer:
volume of the given shape = 896 cubic centimeters.
Step-by-step explanation:
Given a composite figure is made up of a rectangular prism and a square pyramid.
Now we need to find the volume of that composite shape.
So we can find volume of each part then add both to get total volume.
Volume of rectangular prism = (length)(width)(height) = (8)(8)(13)= 832 cubic centimeter
Base area of square pyramid = (length)(width)=(8)(8)=64
Volume of square pyramid. ![=\frac{1}{3}\left(Base\ area\right)\left(Height\right)](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3%7D%5Cleft%28Base%5C%20area%5Cright%29%5Cleft%28Height%5Cright%29)
![=\frac{1}{3}\left(64\right)\left(3\right)](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3%7D%5Cleft%2864%5Cright%29%5Cleft%283%5Cright%29)
![=64](https://tex.z-dn.net/?f=%3D64)
Then total volume of the given shape = 832+64 = 896 cubic centimeters.

Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.
