<span>Found a similar problem with the given table. 

Elapsed time (Minutes)   0    10   20   30    40    50   60   70   80   90
Rate (gallons / minute)   42   40  38   35    35    32   28    20   19   10

Because the interval is every 10 minutes, we will use 10 and multiply it to each rate and get the sum total.

42*10 + 40*10 + 38*10 + 35*10 + 35*10 + 32*10 + 28*10 + 20*10 + 19*10 + 10*10
420 + 400 + 380 + 350 + 350 + 320 + 280 + 200 + 190 + 100
2,990

There will be a total of 2,990 gallons in the tank after 90 minutes. </span>

A total of 363 were sold for the school play. They were either adult tickets or student tickets. The number of student tickets s
timurjin [86]

Answer:

The number of adult tickets sold was 121

Step-by-step explanation:

The general equation is: <em>S</em> + <em>A</em> = <em>T</em>    ;where <em>S</em> means student tickets, <em>A</em> means adult tickets and <em>T</em> means total tickets. We know that <em>S</em> is two times <em>A</em> and <em>T</em> is 363. So, <em>S</em> will be 2x and A will be x. Then, the new equation is 2x + x = 363.

<em>S</em> + <em>A</em> = <em>T</em>  

2x + x = 363  

3x = 363  

x = 363 / 3

x = 121

Adult tickets: <em>A</em> = x = 121

Student tickets: <em>S</em> = 2x = 2 * 121 = 242

The radius of a circle does not change with direction, it stays constant. This, the radius of the bigger circle is 4, and of the smaller circle is 2. Thus, OP equals 4 + 2 = 6. You're correct! :)
