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.

BRAINLIESTTT ASAP! PLEASE HELP ME :)
Gre4nikov [31]

Answer:

θ = 0.896 and 2.246.

Step-by-step explanation:

We will use the identity

sin²θ + cos²θ = 1

and the double angle formula

cos2θ = cos²θ - sin²θ = (1 - sin²θ) - sin²θ = 1 - 2sin²θ

1. Convert the equation to a more solvable form.

\begin{array}{rcll}\sin\theta + 1 & = & \cos2\theta &\\\sin\theta + 1& = & 1-2\sin^{2}\theta & \text{Used the double angle formula}\\f(\theta) = 2\sin^{2}\theta + \sin\theta -2 & = & 0 & \text{Moved terms to left-hand side}\\2u^2 + u - 2 & = & 0 & \text{Substituted u for }\sin\theta\\\end{array}

2. Solve the quadratic

a = 2; b = 1; c = -2

(a) Set up the equation.

u =\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\=\dfrac{-1\pm\sqrt{(1^2 - 4\times 2 \times (-2)}}{2\times2}\\\\=\dfrac{-1\pm\sqrt{1 + 16}}{4}\\\\=\dfrac{-1\pm\sqrt{17}}{4}\\

(b) Evaluate the roots

\begin{array}{rcl}u = \dfrac{-1 - 4.123}{4} & \qquad & u = \dfrac{-1 + 4.123}{4}\\\\u = -\dfrac{5.123}{4} & \qquad & u =\dfrac{3.123}{4}\\\\u = -1.281& \qquad & u =0.7808\\\end{array}

3. Solve for θ

(a) The negative root

u = sinθ = -1.281

sinθ cannot be less than -1. No solution.

(b) The positive root

If sin(x) = a, then

x = arcsin(x) + 2πn and

x = π - arcsin(a) + 2πn

(i) Case 1

u = sinθ = 0.7808

θ = arcsin(0.7808) + 2πn

θ = 0.8959 ± 2πn

If n = 0,  

θ = 0.8959

(ii) Case 2

θ = π - 0.8959 + 2πn

If n = 0,

θ = π - 0.8959 = 2.246

The solutions are θ = 0.8959 and θ = 2.246

The diagram below shows the graph of f(θ) with its roots at 0.896 and 2.246.

Answer:

How to find X and Y value?

If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X.
