Answer:
of the books in the book store are mystery fiction books.
Step-by-step explanation:
Let x represent all the books in the books store.
Then, the fraction of books that are fiction books is 
We have that;
of the fiction books are mystery books.
The fraction of the books at the bookstore that are mystery fiction books is
.
Therefore
of the books in the bookstore are mystery fiction books.
Answer:
Height = 4.78 unit approximately
Step-by-step explanation:
Volume of a one is given by the formula 1/3πr²h
So given that yhe volume of this cone is equal to 320Tr units
And the radius is 8 units.
Lets determine the height of the cone.
V= 1/3πr²h
But V = 320
r = 8
320 = 1/3((3.14)(8)²h
(320*3)/(3.14*64)= h
960/200.96= h
4.777= h
h = 4.78 unit approximately
To solve this problem, we should understand how order of operations works. Perhaps the best way to show you this would be solving the problem with all of the work clearly labeled?
=4[2(21-17)+3] Original Problem
=4[2(4)+3] Solved the Parentheses
=4[8+3] Multiplied the 2 and 4
=4[11] Added the 8 and 3
=44 Multiplied the 4 and 11
An easy way to remember this is PEMDAS, which is an acronym for Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction. Although it will not apply in this scenario (because we have brackets), it will come in handy for many others like this.
Using all of the information above, we can conclude that this expression equals 4.
Area = length x width
So, 36/3 = 12
Width is 12
