Answer:
3/4 in 1/5 of 60 sec
1/5*60=12
3/4 in 12 seconds
3/4*5=15/4=3 3/4
He multiplied 3/4 by 1/5 instead of by its reciprocal , 5.
12/4=3
3 mph
As the scale drawing and the actual car are similar .
so,
height of bumper in drawing
height of bumper in actual car=height of the window in drawing/height of the window in actual car
6 in./16*12 in.=¾ in./height of the window in actual car
height of the window in actual car=¾*16*12/6 in.
=24 inch(Answer )

Step-by-step explanation:
The article talks about technology and how it lead to bigger cities in the past. Because we are reading about prior years, there is no need to talk about the present day.
The ratio to this problem is 750:216
Answer:
-(23/6)π
-(19/6)π
-3π
Step-by-step explanation:
cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t
sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0
Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,
sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π
