Answer:The number of students in each group is 11
Step-by-step explanation:
Let x represent the number of students that attended the field trip.
On the field trip students were split into 5 equal groups. It means that the number of students in each group is x/5
At lunch time 10 students needed to go to the bathroom, while the other 45 went to go eat lunch. It means that the total number of students that attended the field trip was
45 + 10 = 55 students
Therefore, x = 55
The number of students in each group would be
55/5 = 11
Answer:
150 ft
Step-by-step explanation:
The diagram shown gives us a picture of two similar right triangle.
The height of the man is similar to the height of the platform.
To find the height of the platform, multiply the height of the man by the scale factor.
Scale factor = the ratio of any corresponding sides of two similar triangles.
Scale factor = 100 ft ÷ 4 ft = 25
Height of man = 6ft
Therefore, height of platform = 6 ft × 25 = 150 ft
