0.8 times 1200 is 960, which is the number of people when the theatre is 80% full.
Answer:
10.2cm
Step-by-step explanation:
Perimeter is the sum of the lengths of all sides.
1st side: 9cm
2nd side: 7.8cm
Perimeter: 27cm
Perimeter = 1st + 2nd +3rd side of a triangle
27cm = 9cm +7.8cm + 3rd side
3rd side = 27cm - 9cm -7.8cm
= 10.2cm
40 x 5280 = 211200 feet per hour
211200 / 3600 = 58.666 = 59 feet per second
I think it's 60 I'm NOT sure. I just multiplied those three numbers
6x - 1 = 2(-6)
6x = - 11
x = - 11/6
