249 children and 394 adults swam at the public pool.
Step-by-step explanation:
Number of people swam at pool = 643
Receipts = $1161.50
Cost for one child = $1.50
Cost for one adult = $2.00
Let,
x be the number of children
y be the number of adults
According to given statement;
x+y=643 Eqn 1
1.50x+2.00y = 1161.50 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 0.5
Putting x=249 in Eqn 1
249 children and 394 adults swam at the public pool.

step 1
we know that
The total number of successful United States space launches that happened in the years 1957-1995 is equal to
step 2
The numbers of successful United States space launches that happened in the years 1980-1989 is equal to
step 3
The percentage of successful United States space launches that happened in the years 1980-1989 is equal to
step 4
Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989
we know that
In a circle, 360 degrees represent the 100%
so
using proportion
Find out the measure of the central angle by a percentage of 14.68%
