Answer:
B
Step-by-step explanation:
Volume = Volume of cylinder + Volume of semi sphere
= pi*r^2*h+(2/3)*pi*r^3
=pi*(4*12+16/3)=pi*53.3
Let h = weight of the hardcover book.
Let p = weight of the paperback book.
<span>"The hardcover version of a book weighs twice as much as its paperback version."
h = 2p
"</span><span>The hardcover book and the paperback together weigh 5.3 pounds.</span><span>"
h + p = 5.3
The equations are:
h = 2p
h + p = 5.3

Answer: 
Step-by-step explanation:
The formula for calculating mean = sum of each data / total number
Let the age of the sixth person be x , then
mean = 23 + 13 + 17 + 12 + 15 + x / 6
That is :
22 = 23 + 13 + 17 + 12 + 15 + x / 6
22 = 
= 22 x 6
