length of 1 bacteria = 300 = 3 *10^2 nanometers
= 3 * 10^2 / 1 * 10^9 m
= 3 * 10^(2-9)
= 3 * 10^-7 m
Answer:
- 455 adult tickets
- 884 student tickets
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then 1339-a is the number of student tickets sold. The revenue collected was ...
5a + 1(1339-a) = 3159
4a = 1820 . . . . . . subtract 1339, collect terms
a = 455 . . . . . . . . divide by 4; adult tickets sold
(1339-a) = 884 . . . . student tickets sold
455 adult tickets and 884 student tickets were sold.
The answer would be a 28% decrease.
Hope that helps!!
