Answer:
-0.17901368672
Step-by-step explanation:
X = first film....y = second film
x + y = 132
x = 2y - 3
2y - 3 + y = 132
3y - 3 = 132
3y = 132 + 3
3y = 135
y = 135/3
y = 45......so the 2nd film lasted 45 minutes
x = 2y - 3
x = 2(45) - 3
x = 90 - 3
x = 87 <=== the first film lasted 87 minutes
Answer:
90 inches
Step-by-step explanation:
The perimeter of the inscribed triangle is 1/2 that of the enclosing triangle. So, the total of perimeters is ...
(3·16 in)(1 +1/2 +1/4 +1/8) = (48 in)(15/8) = 90 inches
