Answer:
it is invertible
Step-by-step explanation:
First, put each grade in terms of x. Most grades are compared to Sophomores, so I made that x
Freshmen = x + 10
Sophomores = x
Juniors = x + 20
Seniors = (x + 10) + 7 = x + 17
Then, the total number of students = 363, so we’ll make an equation that adds them all up in terms of x to equal 363
(x + 10) + x + (x + 20) + (x + 17) = 363
Combine like terms:
4x + 47 = 363
Subtract 47 from both sides:
4x = 316
Divide both sides by 4:
x = 79
The question was how many seniors there are. Seniors were x + 17, so 79 + 17 = 96
Congruent means the two figures have the same size, shape, and angles. All of the answers are correct.
Square root of 69,081 is 262.832646, so the answer to the nearest tenth will be 262.8. Good luck!
