Eduardo uses the fermi process and the following estimates to determine how many paperback books would fill the community pool he visits. a paperback book is about 12 ft long, 15 ft wide, and 15 ft thick. the swimming pool is about 40 ft long, 30 ft wide, and 5 ft deep. which equation could he have written?

Dimensions of paperback book :

Length = 12 feet

Breadth = 15 feet

Height = 15 feet

Volume of Paperback book =

                                             =  

                                             =  

Dimensions of swimming pool:

Length = 40 feet

Breadth = 30 feet

Height = 5 feet

Volume of swimming pool =

                                             =  

                                             =  

Now we are supposed to find  how many paperback books would fill the community pool he visits.

So, No. of paperback books would fill the community pool:

=

=

=

Thus 2 paperback books would fill the community pool

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
