A gas station has a cylindrical fueling tank that holds the gasoline for its pumps, as modeled below. The tank holds a maximum o

f 20,000 gallons of gasoline and has a length of 34.5 feet.
A metal pole is used to measure how much gas is in the tank.

To the nearest tenth of a foot, how long does the pole need to be in order to reach the bottom of the tank and still extend one foot outside the tank?

[1 ft^3=7.48 gallons ]

Answer:

\boxed{ \text{10.9 ft}}

Step-by-step explanation:

The formula for the volume of a cylinder is

V = πr²h

Data:

V = 20 000 gal

h = 34.5 ft

Calculations:

I assume the gasoline tank is lying on its side, so we are asked to find the diameter of the tank.

(a) Convert the volume to cubic feet

V= 20 000 gal × (1 ft³/7.48 gal) = 2674 ft³

(b) Calculate the radius of the tank

V = πr²h

r² = V/(πh) = 2674/(π × 34.5) = 24.67 ft²

r = √24.67 = 4.967 ft

(c) Calculate the diameter of the tank

d = 2r = 9.934 ft

(d) Calculate the length of the measuring pole

l = d + 1 = 9.934 + 1 = \boxed{ \textbf{10.9 ft}}

Wich equation gives the number of 1/3 inches that are in 5/6 inches

Hello from MrBillDoesMath!

Answer:

(1/3) x = (5/6)


Discussion:

I think you are asking for this equation:

(1/3) x = (5/6) =>            multiply both sides by 3

(1/3) 3 x = (5/6) 3 =>      as (1/3) *3 = 1

x = 5*3/6

x= 15/6

x = 5/2 = 2.5

Thank you,

MrB

the mean of a set of numbers is 120. if one number is increased by 300, the mean increases to 135. how many numbers are in the s
stiks02 [169]

There are 20 numbers in the set.

Given,

Set of numbers is 120

one number is increased by 300

and, mean increases to 135.

To find the how many numbers are in the set?

Now, According to the question:

Let the number of numbers be 'n'

Then, (sum of numbers)/n = 120

or, old sum = 120n

if one number is increased by 300, the new sum = (old sum + 300)

Then, (new sum)/ n= 135

or new sum = 135n = old sum + 300 = 120n + 300

The equation will  be:

135n = 120n + 300

15n = 300

n = 20

Hence, There are 20 numbers in the set.

In the question:

The mean of a set of numbers is 120. if one number is increased by 300, the mean increases to 135.
