If a window is shaped like a parallelogram has an area of 18and 1/3 square feet and the height of the window is 3and 1/3 feet how long is the base of the window .

5.5 feet

Step-by-step explanation:

Area of parallelogram found by taking base * height

So - convert into improper fractions and solve

Short

a/(21÷12= 1.75 pound per dollar)

b/[10÷81= 0.12 mile per minute]

long answer and explanation:

a/
(21÷12= 1.75 pound per dollar )
that's the only answer you need ( )

to double check and make sure:

1.75×12= 21 pound

b/
81÷10= 8.1
one mile every 8.1 minutes

but for 1 minute
1÷8.1= 0.12 mile per minute.

another way same answer
[10÷81= 0.12 mile per minute]
that's the only answer you need [ ]

hope that helps..
