Answer:
3
Step-by-step explanation:
All the triangles are similar, so ...
... 3/y = y/27 . . . . . ratio of short side to long side
... 81 = y² . . . . . . . . multiply by 27y
... 9 = y
The Pythagorean theorem tells you ...
... z² = 3² + 9² = 9 +81
... z² = 90 = 9·10
... z = √(9·10) = 3√10

Answer:
72% of students chose burritos
Step-by-step explanation:
first you would add up the total of kids that said they liked the other two options, which was pizza and sandwiches: 10+4=14
then you would take that number and subtract it from the total of all students: 50-14=36
and then you would take that number and divide it by 50: 36/50=.72
turn that into a percent and you'd get 72%
1/8(30)+1/5(20)= 31/4 = 7.75
