A comic book store is having sale. You can buy 20 comic books for $35. What is cost of 8 comic books during the sale

san4es73 [151]

Answer:

The cost of 8 comic books is $14

Step-by-step explanation:

Given

$20\ books = \$35$

Required

Determine the cost of 8 books

First, we need to determine the cost of 1 book

$20\ books = \$35$

Divide through by 20

$20\ books/20 = \$35/20$

$1\ book = \$35/20$

$1\ book = \$1.75$

Then multiply both sides by 8 to get the cost of 8

$8 * 1\ book = \$1.75 * 8$

$8 \ books = \$14$

Hence;

<em>The cost of 8 comic books is $14</em>

What is the volume of a cone with a diameter of 30 feet and a height of 60 feet use 3.14 for pie

Nesterboy [21]

Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: $\frac{1}{3} *b*h$

$\frac{1}{3} *$ π $*r$ ² $*h$ =

$\frac{1}{3} *3.14*15^{2} *60=\\$

$\frac{1}{3} *3.14*225*60=$

$\frac{1}{3} *3.14*13,500=\\$

$\frac{13,500}{3} *3.14=\\$

$4500*3.14=$

14,130 feet³
