Answer:

Step-by-step explanation:
as if we form an imaginary triangle with this line as hypotenuse
we get
- base = 3 units
- perpendicular = 4 units
using Pythagoras theorem:-
hyponteuse ² = perpendicular ² + base²
hyp² = 4² + 3²
hyp² = 16 + 9

hyp = 5 units

12 goes into 276 23 times.
42 times 10 is 420. hope this helps
Answer:
They can seat <u>520</u> students.
Step-by-step explanation:
Given:
The night school auditorium is able to seat 8 elementary school groups of 65 students each.
Now, use the distributive property to determine the number of students they can seat.
Total number of elementary school groups = 8.
Number of students in each group = 65.
So, using the distributive property to get the number of students they can seat:





Therefore, they can seat 520 students.
