The total fuel needs for the journey is $18.50

Further Explanation

Given:

Average fuel = 8 miles/gallon

Fuel cost = 83 cents/gallon

In order to calculate the journey cost in fuel we need information about the distance between Oban and Stranraer. With doing a little research, we find out that the total distance between to city is approximately 178 miles.

First step

Calculate the fuel needed for the entire journey (x) =

\frac{Total distance}{x gallon} = \frac{average distance}{gallon}

\frac{178}{x gallon} = \frac{ 8}{gallon}

x gallon = \frac{178}{8}  = 22.25 gallon

Total fuel needed for the entire journey is 22.25 gallon

<u>Next step</u>

Calculate the total cost for the journey

= Total fuel x Price/gallon

= 22.25 gallon x 83 cents = 1846.75 cents which is equal to $18.47 or $ 18.50 (to the nearest 5 cents)

Answer:

$18.56

Step-by-step explanation:    

Since we know that distance between Oban and Stranraer is 178.9 miles.

Let us find the number of gallons of fuel used during the journey by dividing total distance traveled by distance traveled per gallon of fuel.

\text{Total number of gallons of fuel used during the journey}=\frac{178.9\text{ miles}}{8\frac{\text{miles}}{\text{gallon}}}

\text{Total number of gallons of fuel used during the journey}=\frac{178.9\text{ miles}}{8}\times \frac{\text{gallon}}{\text{miles}}

\text{Total number of gallons of fuel used during the journey}=22.3625\text{gallon}

Now let us find the total cost of fuel for the journey by multiplying number of gallons of fuel used by cost of per gallon fuel ($0.83).

\text{Total cost in fuel during the journey}=22.3625\times\$0.83

\text{Total cost in fuel during the journey}=\$18.560875\approx \$18.56

Therefore, the journey will cost $18.56 in fuel.

A pole-vaulter uses a 15-foot-long pile. She grips the pole so that the segment below her left hand is twice the length of the s
Shalnov [3]
Let x + 1.5 be length of segment above left hand
Let 2x be length of segment below left hand

15 = x + 1.5 + 2x
15 = 3x + 1.5
15 - 1.5 = 3x
13.5 = 3x
13.5/3= 3x/3 
4.5 = x
x = 4.5
This is the length above the left hand. 

2x must be then 4.5*2 = 9 foot
This is the length below the left hand. 

Checking
4.5 + 9 + 1.5 = 15 foot 

Adding length below left hand & length of left hand to right hand:
9 + 1.5 = 10.5
The right hand is hence 10.5 foot far up the pole.
