Answer:
4.8 hours
Step-by-step explanation:
6 hours = 360 minutes (6x60)
360/5 = 72 (minutes per person worked)
72/2= 36 (person working at half productivity)
36x 8= 288 (total minutes of 8 people working at half productivity)
288/60= 4.8 (cover minutes back to hours)

Answer:
16/25
Step-by-step explanation:
length of screen B=44*(5/4)=55cm
and its width=32*(5/4)=40cm
so, screen B had dimensions 55cm by 40 cm
screen A area=44*32 cm sqr
screen B area=55*40 cm sqr
so, model A screen area/model B screen area
=(44*32)/(55*40)
=16/25
The answer is 80’, because is the corresponding angle of 1, so it must be the same answer as 1 angle.
