189 tickets were purchased on Saturday. The ratio of children's tickets to adult tickets is 8:1, indicating that 8 times as many children's tickets were sold compared to adult tickets. Let c represent the number of children's tickets and a the number of adult tickets. Therefore, 8a = a + 147. By subtracting a from both sides, we find 7a = 147. Upon dividing both sides by 7, we find a = 21 adult tickets. By multiplying the number of adult tickets by 8, we discover that 21 * 8 = 168 children's tickets. Adding these together gives a total of 168 + 21 = 189 tickets sold on Saturday.
Answer:

Step-by-step explanation:
Given the quadratic equation:

To solve it, we follow these steps:
1. Rearrange the terms to one side of the equation:

2. Utilize the Quadratic formula

.
In this case, we can identify that:

Then, substituting these values into the Quadratic formula gives us the following solutions:


Here are 3 questions with their respective answers.1) Find
Answer: 4.Explanation:This expression indicates the
limit as the function f(x) approaches 2 from the right side.You should apply the function (the line) from the right side of 2 and get as close to x = 2 as you can.
That line has an open circle at
y = 4, which is the limit we are looking for.
2) Analyze the graph to see if the limit exists.Answer: 

To find each limit,
utilize the function approaching from the direction of x.It's important to note that since the two limits differ, it is concluded that the limit of the function as x approaches 2 does not exist.
3)
Answer: -1
To determine the limit as the function approaches 3 from the left,
follow the line ending with an open circle at (3, -1).Hence, the limit is -1.
When there is one table (t=1), you can place 6 chairs (c=6) around it: 2 along the length of each side and 1 at each end.
With t=2, where the tables are positioned end to end (joined at the width), c=10, that means 4 chairs along each side of the joined tables and 1 chair at each end. Each additional table increases the number of chairs by 4, thus we can express this as c=4t+2, with the constant 2 representing the individual chair at each end. If the tables are spread apart, then c=6t.
1 nanometer = 1 * 10^9 meters
therefore, 1 nanometer = 1 * 10^7 centimeters
375 nanometers = 3.75 * 10^5 centimeters
