Step-by-step explanation:
Hello There!
First work out the number of shelves per bookcase:
65/13 = 5
It is 5 shelves per bookcase.
6 x 5 = 30.
Therefore 32 shelves are enough to make 6 bookcases.
Hope This Helps You!
Good Luck :)

Answer:
The answer to your question is: # of times = 60.7
Step-by-step explanation:
data
7.4 billion people
each person occupied 13 inches
Earth circumference = 25000 miles
length of the lines = 13 in x 7.4 billion people
= 13 x 7 400 000 000
= 9.62 x 10 ¹⁰ in
Convert in to miles
1 mile --------------- 63360 in
x mi --------------- 9.62 x 10 ¹⁰ in
x = 1518308.1 mi
Now divide, the line of people by the circumference
# of times = 1518308.1 mi / 25000 mi = 60.7
Answer:
15.22
Step-by-step explanation:
The equation of the circumference of a circle is 2(pi)r
This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)
so a simple formula is:
arc length in radians X radius
radius = 4 cm
the area that the question wants is the oposite
of the 142 degree section so 360 - 142 = 218
218 degrees * (pi/180) = 3.80482 rad
3.80482 * 4 = 15.21928 cm
