Answer:
2880
Step-by-step explanation:
V=whl=12·12·20=2880
Answer:
9
Step-by-step explanation:
X=Tickets bought
A=$40+$8x
B=$67+$5x
After 1 ticket bought it would be:
A=$48
B=$72
After 9 tickets bought:
A=$112
B=$112
From this you can see that Plan B is better for ones who would see 9+ movies as the recurring price would be lower. If you would only go to watch a couple movies, Plan A would be better.
Answer: 1/2
Step-by-step explanation:
Number of red balloons = 17
Number of purple balloons = 11
Number of orange balloons = 3
Number of green balloons = 1
Number of yellow balloons = 2
Total number of balloons = 34
The probability that a randomly selected balloon will be red will be:
= Number of red balloons/Total number of balloons
= 17/34
= 1/2
Doug because his sequence follows a rule of multiplying by -1/2
Hope I got it right for your sake.
2040 = n/2(20+(n-1)4)
4080 = n(20+4n-4)
4080= 20n +4n^2 -4n
1020 = 4n + n^2
n^2 +4n -1020 =0
use common formula (can't write out so just look at answers. sorry)
which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
