Answer:
B. -1
Step-by-step explanation:
The relevant points on the graph are (1, 3) and (4, 0). The average rate of change can be found using the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (0 -3)/(4 -1) = -3/3 = -1
The average rate of change from x = 1 to x = 4 is -1.
ANSWER
![3840 {ft}^{3}](https://tex.z-dn.net/?f=3840%20%7Bft%7D%5E%7B3%7D%20)
EXPLANATION
The room represents a rectangular prism or a cuboid.
The dimensions of the room are 30 feet by 16 feet by 8 feet(height).
The volume of a rectangular prism is
![= base \: area \: \times \: height](https://tex.z-dn.net/?f=%20%3D%20base%20%5C%3A%20area%20%5C%3A%20%5Ctimes%20%5C%3A%20height)
Substitute the given values
![= 30 \times 16 \times 8 {ft}^{3}](https://tex.z-dn.net/?f=%20%3D%2030%20%5Ctimes%2016%20%5Ctimes%208%20%7Bft%7D%5E%7B3%7D%20)
Simplify:
![= 3840 {ft}^{3}](https://tex.z-dn.net/?f=%20%3D%203840%20%7Bft%7D%5E%7B3%7D%20)
Hence the cubic feet of air in the room is 3,840ft³.
The number of adult tickets and children tickets sold were 92 and 220 respectively
What differentiate adult tickets from children's
The adult tickets can be represented by a while children's ticket is c
The total number of tickets sold which is 312 means the sum of a and c
a+c=312
Total value of adult tickets=a*12
total value of children tickets=c*5
12a+5c=2204
Solve for a in the first equation
a=312-c
substitute for a in the second equation
12a+5c=2204
12(312-c)+5c=2204
3744-12c+5c=2203
3744-2203=12c-5c
1541=7c
c=1541/7
c=220
a=312-220
a=92
