Step-by-step explanation:
I used the clculater
Let s = # of students in the sixth grade. 60% of these, or 0.60s, ate pizza: thus, 0.60s = 36. Solving for s, s = 36/0.60 = 60.
There are 60 students in the sixth grade.
Pythagoras, cool.
30^2 is 900
15^2 is 225
26^2 is 676
676+225 isn't 900 so it isn't A.
10^2=100
26^2=676
24^2=576
100+576=676 so B is a right angled triangle.
Hope this helps :)
