Answer:
10 terms
Step-by-step explanation:
equate the sum formula to 55 and solve for n
n(n + 1) = 55 ( multiply both sides by 2 to clear the fraction )
n(n + 1) = 110 ← distribute parenthesis on left side
n² + n = 110 ( subtract 110 from both sides )
n² + n - 110 = 0 ← in standard form
Consider the factors of the constant term (- 110) which sum to give the coefficient of the n- term (+ 1)
the factors are + 11 and - 10 , since
11 × - 10 = - 110 and 11 - 10 = + 1 , then
(n + 11)(n - 10) = 0 ← in factored form
equate each factor to zero and solve for n
n + 11 = 0 ⇒ n = - 11
n - 10 = 0 ⇒ n = 10
However, n > 0 , then n = 10
number of terms which sum to 55 is 10
5782/24=240 since we round down to s whole.
Multiply again by 24.
240*24=5760
There are 5782-5760=22 priority seats.
The correct answer is 22.

Step-by-step explanation:
We can simplify this problem down by realizing that the amount of girls over 200 will get us our percentage as a decimal.
Looking at this table, we can see that 
girls were asked. So, 
, and 
.
We can also see that 
people preferred video games, so 
, and 
.
Hope this helped!

Step-by-step explanation:
Answer:6000
Step-by-step explanation:3 quarters is equal to 9/12. And 1/3 is equal to 4/12
If it is 9/12 full and 2500 gallons are drained then there are 4/3 left
9/12 - 4/3 is equal to 5/12.
Thta means 2500 gallons is 5/12 of the whole container
5/12 divided by 5 is 1/12
And 2500 divided by 5 is 500
That means every 1/12 of the container can fill 500 gallons
Do then 500 times 12 is 6000
Sorry I am really bad at explaining
