Astack of books is 5 feet high of the average book is 3 inches hugh how many books are in the stack

20 books

Step-by-step explanation:

Given : A stack of books is 5 feet high of the average book is 3 inches High.

To Find: How many books are in the stack?

Solution:

1 foot = 12 inches

5 feet = inches

Height of stack = 60 inches

Height of 1 book = 3 inches

Number of books in a stack =

                                              =

                                              =

Hence,There are 20 books in a stack.

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
