One of the two positive integers is 5 less than the other. If the product of the two integers is 24, find the integers.

Studentka2010 [4]

Hello from MrBillDoesMath!

Answer:

3,8

Discussion:

Let "n" and "p" be the two positive integers. Then

n = p - 5 (*)

and

np = 24 (**)

Substituting (*) in (**) gives

np = 24 => as p = n+5

n(n+5) = 24 =>

n^2 + 5n - 24 = 0 => factor polynomial (n+8)(n-3)

So n = 3 or -8 but as n is positive, n = 3 Then p = n + 5 = 8

Check:

Is n (3) 5 less than p (8). Yes

Does np = 3 *8 24. Yes

Thank you,

A silo is a composite of a cylindrical tower with a cone for a roof. Find the volume of the silo if the

qaws [65]

Answer:

5127079.21 cubic feet

Step-by-step explanation:

The silo is in the shape of a cylinder and a cone.

The volume of the silo will be the sum of the volumes of the cylinder and the cone.

Therefore, its volume is:

$V = \pi r^2h + \frac{1}{3} \pi rH$

where r = radius of cylinder and cone

h = height of cylinder

H = height of cone

The radius of the base is 120 feet, the height of the roof (cone) is 25 feet. The height of the entire silo is 130 feet. This means that the height of the cylinder is:

130 - 25 = 105 feet

Therefore, the volume of the silo is:

$V = (\pi * 120^2 * 105) + (\frac{1}{3} * 120^2 * 25)\\\\V = 4750088.09 + 376991.12\\\\V = 5127079.21 ft^3$

The volume of the silo is 5127079.21 cubic feet.
