Answer:

$16.98 per gallon

Step-by-step explanation:

We can set up a equation using ratios:

[tex]\frac{67.92}{4}=\frac{x}{1}[/tex]

Solve by cross multiplication (multiply the numerator of the first fraction by the denominator of the second fraction and the denominator of the first fraction by the numerator of the second fraction):

67.92=4x

Divide both sides by 4 to isolate x

$16.98

The general form of the equation of a circle with center at (a, b) and radius of length m is written as [tex](x-a)^2+(y-b)^2 = m^2[/tex].

The general form of the equation of a circle is written as,

[tex](x-h)^2+(y-k)^2 = R^2[/tex]

where (h, k) is the coordinates of the center of the circle, while R is the radius of the circle.

We have already discussed the general form of the equation of a circle, substituting the values into it,

[tex](x-h)^2+(y-k)^2 = R^2\\\\(x-a)^2+(y-b)^2 = m^2[/tex]

Hence, the general form of the equation of a circle with center at (a, b) and radius of length m is written as [tex](x-a)^2+(y-b)^2 = m^2[/tex].

Answer:

In order: y = 29, 8, -1, 2, 17

Step-by-step explanation:

Simply plug in what x equals to get the coordinating y!

When x = -2       6(-2)² - 3(-2) - 1 = 29

When x = -1        6(-1)² - 3(-1) - 1 = 8

When x = 0        6(0)² - 3(0) - 1 = -1

When x = 1         6(1)² - 3(1) - 1 = 2

When x = 2        6(2)² - 3(2) - 1 = 17

We have: SM = TM ( because M is the midpoint )

So: x + 12 = 8x - 2

=> x - 8x = -2 - 12

=> -7x = -14

=> x = (-14) / (-7) = 2

Answer: x = 2

Answer:

x =53.85

Step-by-step explanation:

Let x be the original price

If the price is 22% of, you will pay 100% -22% = 78%

x * 78% = 42

Change to decimal form.

78x = 42

Divide each side by .78.

78x/.78 = 42/.78

Rounding to the nearest cent

x =53.85

say the regular price is "x", which is the 100% value of the shoes, but today they're 22% off, that means 100% - 22% = 78%, so the sale price is really 78% of the regular price, we know that's 42 bucks, so

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 42&78 \end{array}\implies \cfrac{x}{42}=\cfrac{100}{78}\implies \cfrac{x}{42}=\cfrac{50}{39} \\\\\\ 39x=2100\implies x=\cfrac{2100}{39}\implies x\approx 53.85[/tex]

The equation  [tex]k^2-20k+100=0[/tex] will have exactly one real solution when k=10.

Here, you will find k from the value of the discriminant for the given quadratic equation.

The standard form for a quadratic equation is: [tex]ax^{2}+bx+x=0[/tex]. Where: a, b, and c are your coefficients.

Then, the given equation [tex](k-5)x^2-kx+5=0[/tex]  is a quadratic equation.  Where:

                                                  [tex]a=k-5\\ \\ b=-k\\ \\ c=5[/tex]

The number of solutions for a quadratic equation is determined by the discriminant (D) that can be calculated from the expression: [tex]b^2-4a*c[/tex]. When:

                                       [tex]D=b^2-4a*c\\ \\ D=(-k)^2-4*(k-5)*5\\ \\ D=k^2-20*(k-5)\\ \\ D=k^2-20k+100[/tex]

You should find the value for k for which the given equation has only one real solution. Therefore, D=0. For this, solve the quadratic formula for the equation  [tex]D=k^2-20k+100=0[/tex] .

                                    [tex]k_{1,2}=\frac{\(-b\pm \sqrt{(b)^2-4\cdot \:a\cdot \:c}}{2\cdot \:a}\\\ \\ k_{1,2}=\frac{\(20\pm \sqrt{(-20)^2-4\cdot \:1\cdot \:100}}{2\cdot \:1}\\ \\ k_{1,\:2}=\frac{20\pm \sqrt{0}}{2\cdot \:1}\\ \\ k=\frac{20}{2}=10\\[/tex]

Hence, k=10 for the equation  [tex]k^2-20k+100=0[/tex] has exactly one real solution.

Answer:

Length = 200 m

Breadth = 175 m

Step-by-step explanation:

Perimeter of the rectangular field = Total cost ÷ rate per metre

                                                        = 12000 ÷ 16

                                                        = 750 m

Length : breadth = 8 : 7

Length = 8x

Breadth = 7x

Perimeter = 750

2*(length + breadth) = 750

2*(8x + 7x) = 750

2* 15x = 750

  30x = 750

      x = 750/30

x = 25

Length = 8x = 8*25 = 200 m

Breadth = 7*25 = 175 m

Answer:

8 convertibles

Step-by-step explanation:

Well, first we are going to assume the ratio for the convertibles and non-convertibles are the same.

So the company rented 4 convertibles and 30 others.

This makes the ratio 4:30

30+4=34 68 is double of 34 so it is logical to double the ratio to get 8:60. So that means there should be 8 convertibles.

I hoped this helped.

8 convertibles are expected in many of the first 68 vehicles rented today should you expect to be convertibles.

When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however, other symbols like the "*" sign are also occasionally used.

There is a total number of vehicles is as:

30 other vehicles + 4 convertibles = 34 cars

To  find 68 vehicles

34 * 2 = 68

Therefore this implies :

30 * 2 other vehicles + 4 * 2 convertibles

= 68 cars

60 other vehicles and 8 convertibles
