Answer:
Ryan's revenue last month if he sold 16 new books and 25 old books
is $337.50.
Step-by-step explanation:
The number of old books sold by Ryan = 25
The cost of each old book = $5.50
⇒ Total amount earned by selling 25 old books = 25 x $5.50
= $137.5
The number of new books sold by Ryan = 16
The cost of each new book = $12.50
⇒ Total amount earned by selling 16 new books = 16 x $12.50
= $200
Hence Total amount earned by Ryan
= Amount earned by selling old books + Amount by selling new books
= $137.5 + $200
= $337.50
or, Total amount earned by Ryan = $337.50
Hence Ryan's revenue last month if he sold 16 new books and 25 old books is $337.50.
It can have a parameter of 60 if it is 3in wide and 27 in long.
We find this by looking at the factors of 81.
3 and 27 are factors and if using the formula given we see that length = 30-3 = 27.
Using these factors of 81, the parameter would be 27 + 27 + 3 + 3 which results in 60.
Pyramid volume: 1/3 b h = 1/3 (9^2)*10=270 cubic centimeters
Cube volume: 4*4*4=64
270/64=4.2
