1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 2 ft * 2 ft=12 ft³
Therefore:
A machine can fill 12 ft³ in 3 seconds.
2) we calculate the volume of the second carton.
volume=length x width x heigth
volume=4 ft * 5 ft * 6 ft=120 ft³
3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.
12 ft³---------------------3 seconds
120 ft³-------------------- x
x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.
answer: 30 seconds.

Answer:
each student must make 5 posters in one hour
Step-by-step explanation:
The equitable thing is that each student makes an equal number of posters at the established time, knowing that there must be 60 posters and there are 12 students, these numbers must be divided so we will have the same amount for each student:
60/12 = 5
Which means that each student must make 5 posters in one hour so that everything turns out well
A square has four 90° angles. So:
15x-30=90 add 30 to both sides
15x=120 divide both sides by 15
x=8°
