Which of the following numbers is divisible by 5, 6, and 9? A. 54,183 B. 45,803 C. 81,450 D. 18,045
horrorfan [7]
Straight away it can't be A or B because the last/ones digits aren't multiples of 5.

For something to be divisible by 9, add all the digits up and see if it is a multiple of 9:
This works for both C and D, as both numbers have digits which add up to 18.

However, only C is divisible by 6. D is an odd number and hence it is eliminated. For something to be divisible by 6, it must be divisible by 2 (an even number) and 3 (digits add to a multiple of 3). C does both.
Hence C is the answer.

Hope this helped

Answer:

The height of the water is 60.5\ ft

Step-by-step explanation:

step 1

Find the volume of the tank

The volume of the inverted right circular cone is equal to

V=\frac{1}{3}\pi R^{2} H

we have

R=16\ ft

H=96\ ft

substitute

V=\frac{1}{3}\pi (16)^{2} (96)

V=8,192\pi\ ft^{3}

step 2

Find the 25% of the tank’s capacity  

V=(0.25)*8,192\pi=2,048\pi\ ft^{3}

step 3

Find the height, of the water in the tank  

Let

h ----> the height of the water  

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

\frac{R}{H}=\frac{r}{h}

substitute

\frac{16}{96}=\frac{r}{h}\\ \\r= \frac{h}{6}

where

r is the radius of the smaller cone of the figure

h is the height of the smaller cone of the figure

R is the radius of the circular base of tank

H is the height of the tank

we  have

V=2,048\pi\ ft^{3} -----> volume of the smaller cone

substitute

2,048\pi=\frac{1}{3}\pi (\frac{h}{6})^{2}h

Simplify

221,184=h^{3}

h=60.5\ ft
