We have a group of 169 students that needs to be seated in a square formation. Then, the number of rows has to be the square root of 169 :-

Then, a square of 13 rows and 13 columns will fit the 169 students.
If the number of students is 1024, then the number of rows <em>N </em>can be calculated as :-



<h3>
<u>Final Answer :-</u></h3>
169 students will seat in a 13×13 formation.
1024 students will seat in a 32×32 formation (N=32)

Every triangle has 180 degrees when you add there angles so you know that they will add up to 180
they are right triangles so the right angle has 90 degrees
so for the yellow triangle
90+45+x=180
135+x=180
45=x
we can tell where the purple and yellow triangle touch is 90 so 45+x=90 to find that angle which is 45
and the other one is 45
so there are two 90 degree angles and three 45 degree angles.
I hope that made sence
Answer:

Step-by-step explanation:
The first thing that would need to be done is solving for y. This problem has already done this. The next step is to exchange y for 
That is all. This would mean that the function notation for the equation would be: 
Answer: 2 buses and 4 vans would be needed
Step-by-step explanation:
Let x represent the number of buses that would be needed.
Let y represent the number of vans that would be needed.
There will be six drivers, and two different types of vehicles. This means that
x + y = 6
142 students are going on a field trip. A bus can hold 51 people while a van can hold 10. This means that
51x + 10y = 142 - - - - - - - - - - - 1
Substituting x = 6 - y into equation 1, it becomes
51(6 - y) + 10y = 142
306 - 51y + 10y = 142
- 51y + 10y = 142 - 306
- 41y = - 164
y = - 164/ - 41
y = 4
x = 6 - y = 6 - 4
x = 2
That's a simple question.
Ans: If both numbers can be divided to equal a whole number, then it can be simplified.
Example: 35:7 (this is your ratio) divided by 7 = 5:1
