5 0

Answer:

Step-by-step explanation:

First find the number of liters needed to go 12500 km

Fuel = 12500 km * (8.85 L / 100 km)

Fuel = 1106.25 Liters

Now that we know the number of liters we need, we can find the cost.

1106.25 L * 158 c / L

174787.5 cents.

I fear going any further because I don't know where you reside. If you live in a place where they have dollars, then you can divide by 100 to get the dollar amount

1747875 / 100 = 1747,88 dollars

How many times does 5.4 go into 60 if it starts at -18?
photoshop1234 [79]

Answer:

14 \frac{4}{9}

Step-by-step explanation:

starting at -18 you must add 5.4 until you reach 60

-18 + 5.4 = -12.6          once (1)

-12.6 + 5.4 = -7.2         twice (2)

-7.2 + 5.4 = -1.8            thrice (3)

-1.8 + 5.4 = 3.6              fourth (4)

3.6 + 5.4 = 9                  fifth (5)

9 + 5.4 = 14.4                 sixth (6)

14.4 + 5.4 = 19.8             seventh (7)

19.8 + 5.4 = 25.2            eighth (8)

25.2 + 5.4 = 30.6            ninth (9)

30.6 + 5.4 = 36                tenth (10)

36 + 5.4 = 41.4                 eleventh (11)

41.4 + 5.4 = 46.8               twelth (12)

46.8 + 5.4 = 52.2               thirteenth (13)

52.2 + 5.4 = 57.6                fourteenth (14)

since 57.6 + 5.4 is over 60, we need to find the difference in how much we need

57.6 - 60 = -2.4

we need 2.4 so subtract by 5.4

5.4 - 2.4 = 3

therefore we should divide

\frac{2.4}{5.4} = 14.444...

which means it goes into 60 (starting at -18) 14.444... repeating times

another way to find the answer is

add 18 + 60

18 + 60 = 78

78/5.4 = 14.444... repeating or 14 \frac{4}{9}

hope this helps:)

A geographer found that the land area of Aruba is 75 square miles and the land area of Bermuda is 19 square miles. Based on thes
MakcuM [25]

The interpretation of<em> </em><em>x</em> in the equation 75•x + 19•y = T, used by the geographer, based on the land area of Aruba, 75 m², and Bermuda, 19 m², is the population in a square mile of Aruba

<h3>Which method can be used to find the interpretation of <em>x </em>in the equation?</h3>

The land area of Aruba = 75 m²

Land area of Bermuda = 19 m²

The total number of residents is given in the question by the equation;

75•x + 19•y = T

Therefore;

x = The number of people in a square mile in Aruba

y = The number of people in a square mile in Bermuda

Which gives;

  • The interpretation of the variable, <em>x </em>in the context is the population of Aruba per square mile.

a shopkeeper purchased a TV at ₹15,000 and gives a discount of 20% on its marked prize and still got a profit of 8% . find the m
Setler79 [48]

\huge\sf\underline{Answer}

\sf\longrightarrow selling \: prize \:   =  \frac{100 + profit\%}{100}  \times cp

\sf\longrightarrow  \frac{108}{100}  \times 15000 = 16200

Let the marked prize of the TV be x .

\sf\longrightarrow discount = 20\% \: of \: x \:  =  \frac{20}{100}x =  \frac{x}{5}

We have SP = MP - Discount

\sf\longrightarrow 16200 \:  =  \: x -  \frac{x}{5}

\sf\longrightarrow 16200 \:  =  \frac{4x}{5}

\sf\longrightarrow x \:  =  \: 20250

<em>Hence </em><em>,</em><em> </em><em>T</em><em>he </em><em>marked</em><em> </em><em>prize</em><em> </em><em>of </em><em>the </em><em>TV </em><em>is </em><em>₹</em><em>2</em><em>0</em><em>,</em><em>2</em><em>5</em><em>0</em><em> </em><em>.</em>

<em>Hope </em><em>it </em><em>helps </em><em>~</em><em> </em>

Answer:

\large\boxed{\theta=-\dfrac{\pi}{4}+k\pi\ or\ \theta=k\pi}\ for\ k\in\mathbb{Z}

Step-by-step explanation:

\tan^2\theta+\tan\theta=0\\\\\tan\theta(\tan\theta+1)=0\iff\tan\theta=0\ \vee\ \tan\theta+1=0\\\\\tan\theta=0\Rightarrow \theta=k\pi\ \text{for}\ k\in\mathbb{Z}\\\\\tan\theta+1=0\qquad\text{subtract 1 from both sides}\\\\\tan\theta=-1\Rightarrow\theta=-\dfrac{\pi}{4}+k\pi\ \text{for}\ k\in\mathbb{Z}
