A middle school took all of its 6th grade students on a field trip to see a ballet. The students filled 1898 seats, which was 73% of the total number of seats in the theater. How many total seats were in the theater?

x = 2600 seats.

Step-by-step explanation:

Let the total number of seats be x.

Given the following data;

Number of seats occupied = 1898 seats

Percentage = 73%

To find the total number of seats;

Translating the word problem into an algebraic equation, we have;

Cross-multiplying, we have;

x = 2600 seats.

Therefore, the total number of seats in the theater are 2600 seats.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
