To find the number of chaperones, you could find the total number of students that are going on the field trip and then break this number into groups of 8.
(158 + 139)/8
297/8 = 37.125
You will need a minimum of 38 chaperones for the 297 students. If there is any remainder(decimal) you will need an extra chaperone so the groups do not exceed 8.

Answer:
x ≈ 29.4 ft
Step-by-step explanation:
The model is a right triangle.
Using the tangent ratio
tan40° = = ( multiply both sides by 35 )
35 × tan40° = x , then
x ≈ 29.4 ft ( to 1 dec. place )
We know that formular for volume of pyramid=area of base ×height
the area of the base is 1/2×base×height
=1/2×15×14
=105cm²
the given volume is 270cm³
∴height=volume÷base area
=270cm³÷105cm²
=
=
A+7b+12ab ,
I hope it helps you and best of wishes!!
