To find the surface area of a pyramid the formula is:
SA - Surface Area
B - Base
n - number of sides of the pyramid not includung the base
b - length of one side of the base
l - slant height
SA = B + 1/2 nbl
Since we know everything but the "l" we can solve for "l". I will replace "l" with x to avoid confusion.
336 = 144 + (4 * 12 * x) / 2
336 - 144 = 144 - 144 + (4 * 12 * x) / 2
192 = (4 * 12 * x) / 2
192 = 48x / 2
192 = 24x
192 / 24 = 24x / 24
x = 8
Slant Height = 8 inches<span />

Find the height of a cone with volume 4034.66 cm^3 and radius 13 cm.
pav-90 [236]
Volume of cone=4034.66cm^3
Pi×r^2×h/3=4034.66
Pi×13×13×h=4034.66×3
22×13×13×h/7=4034.66×3
h=4034.66×3×7/13×13×22
h=45.57
So h=45.6cm

The height in feet above the water of a diver can be modeled by ℎ() = −16*2 − 16 + 192, where t is the time in seconds after the
Maurinko [17]

h(t) is the height of the diver in feet above the water

Now it asks about the time at which diver reaches the water

When diver reaches the water , the height of diver from water should be zero

So we plug h(t) =0

So

-16t^2 -16 t +192 =0

divide whole equation by -16

t^2 +t -12 =0

we can now factor the quadratic equation

So we get

(t+4)(t-3) =0

plug each factor equal to zero and solve for t

t+4 =0 and t-3 =0

So t=-4 and t=3

Now time cannot be negative , So t=3

So time = 3 seconds

It takes 3 seconds for the diver to reach the water

Jessica and Josh are selling Entertainment Books to raise money for the art room at their school. One book sells for $15. Jessic
melisa1 [442]
<h2><u>Answer</u><u>:</u><u>-</u></h2>

Jessica sells = 240 books,

Josh sells = 16 books.

<h3>Given:-</h3>

The price of one book is = $15

Jessica sold 15 times more books than Josh.

In total, they have sold 256 books.

<h3>Solution:-</h3>

We can easily find the answer using variables.

Let,

Josh sold a total of x books whereas Jessica sold a total number of 15x books.

together they sold 16x books.

So we can form the equation

16x= 256

by solving this equation we will get x=16

So, Josh sold 16 books and Jessica sold 16×15=240 books in total.
