Answer:
Number of adult tickets sold = 128
Number of student tickets sold = 384
Step-by-step explanation:
Given that:
There are two types of tickets:
1. Student tickets
2. Adult tickets
As per the question statement, number of student tickets sold were three times the adult tickets sold.
Let the number of adult tickets sold =
So, number of students tickets sold =
Total number of tickets sold = Number of adult tickets sold + Number of student tickets sold = 512
Therefore, the answer is:
Number of adult tickets sold = 128
Number of student tickets sold = = 384
Answer:
75 mph
Step-by-step explanation:
A biker must circle a 12-mile track twice. His average speed must be 60 mph.
So, the average time required to cover the distance is hours.
Now, on his first lap, he averaged 50 mph.
So, he covered this 12 miles track in hours.
Hence, he has to cover the next 12 miles track in (0.4 - 0.24) = 0.16 hours.
Therefore, his average speed in the second round must be mph to qualify. (Answer)
Answer:
The property shown in matrix addition given is "Additive Inverse Property"
Step-by-step explanation:
First of all lets define what a matrix is.
A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.
There are several addition properties for matrices.
One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.
Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.
Hence,
The property shown in matrix addition given is "Additive Inverse Property"
