An airplane is 180 feet
long. Blake makes a
scale model of the
airplane at 1:60 of its
actual size. How long is
the model?

3 feet

Step-by-step explanation: First, since the model is scaled down from the airplane, we set the ratio as 1:60=x:180, or in fraction form 1/60=x/180. Solving for x, we find that x=3.

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
