Answer:
Step-by-step explanation:
39 cars every 3 hrs.......that means (39/3) = 13 cars every hr
and if its 13 cars every hr....in 7 hrs, there will be (7 * 13) = 91 cars <==
you can either do it that way....the unit rate way...OR
you can set it up as a proportion...
39 cars to 3 hrs = x cars to 7 hrs...
39 / 3 = x / 7....cross multiply
(3)(x)= (39)(7)
3x = 273
x = 273/3
x = 91 <====
either way, u get the correct answer
It cannot be expressed as a mixed fraction. Dividing 36 by 4 gives 9 which is a whole number.

Answer:
C) 120 square feet
Step-by-step explanation:
Note that the bed is in the shape of a <em>triangle</em>. You are also finding the area of the bed (Use the formula Area = 1/2(base * height)).
The base = 20, height = 12. Plug in the corresponding numbers to the corresponding variable.
A = 1/2(20)(12)
Simplify.
A = 1/2(20)(12)
A = (20 * 12)/2
A = (10 * 12)
A = 120
C) 120 square feet is your answer.
