Divide the right hand side by 4;

[tex]x = \dfrac{1 \pm 2\sqrt{2}}{2}[/tex]

[tex]x = \dfrac{1 + 2\sqrt{2}}{2} \ or \ \dfrac{1 - 2\sqrt{2}}{2}[/tex]

Answer:

About 609,000 Cowboy stadiums could fit inside of Mount Everest

Step-by-step explanation:

we have

The estimate volume of Mount Everest is at around [tex]2,413\ km^{3}[/tex]

The Dallas Cowboys Stadium has a volume of [tex]140,000,000\ ft^{3}[/tex]

step 1

Convert ft³ to km³

we know that

1 km=3,280.84 ft

so

[tex]140,000,000\ ft^{3}=140,000,000*(1/3,280.84)^{3}=0.003964\ km^{3}[/tex]

step 2

To find how many Cowboy stadiums could fit inside of Mount Everest, divide the volume of Mount Everest by the volume of the Dallas Cowboys Stadium

[tex]2,413/0.003964=608,729[/tex]

Round to the nearest Thousands

[tex]608,729=609,000[/tex]

The volume of Mount Everest is about 609,000 times greater than the volume of the Dallas Cowboys Stadium

To estimate how many Dallas Cowboys stadiums could fit inside Mount Everest, we converted the volume of the stadium to cubic kilometers and then divided Mount Everest's volume by this number, resulting in approximately 608,845 stadiums.

Calculating the Volume of Mount Everest Compared to the Dallas Cowboys Stadium

To estimate how many Dallas Cowboys stadiums could fit inside of Mount Everest, we need to convert the volume of both structures to the same units and then perform a division.

We have the volume of Mount Everest as approximately 2,413 cubic kilometers. To convert the volume of the Dallas Cowboys Stadium from cubic feet to cubic kilometers, we use the conversion factor of 1 cubic kilometer equals 35.3147 million cubic feet:

Cowboys Stadium volume in cubic kilometers = 140 million cubic feet × (1 cubic kilometer / 35.3147 million cubic feet) = 3.9642 × 10-3 cubic kilometers.

Now, we can find how many Cowboys stadiums fit into Mount Everest:

Mount Everest volume / Cowboys Stadium volume = 2,413 cubic kilometers / 3.9642 × 10-3 cubic kilometers ≈ 608,845.

Therefore, approximately 608,845 Dallas Cowboys stadiums could fit inside of Mount Everest's volume.

To evaluate the expression (9.08 × 10⁶) - (2.25 × 10⁵), align the exponents and then subtract the base numbers, resulting in (8.855 × 10⁶) expressed in scientific notation.

To evaluate the expression (9.08 × 10⁶) - (2.25 × 10⁵) and express the result in scientific notation, we will align the exponents and then subtract the base numbers. Since the exponents are not the same, we need to adjust the smaller exponent to match the larger one.

First, we rewrite (2.25 × 10⁵) with a base of 10⁶, which becomes (0.225 × 10⁶). Now we can subtract:

(9.08 × 10⁶) - (0.225 × 10⁶) = (9.08 - 0.225) × 10⁶

Performing the subtraction, we get:

(8.855 × 10⁶)

Answer:

6x + 1

3x + 3

6x + 9

Step-by-step explanation:

1)

To find the missing number, compare both sides of the equation. If the variable terms are the same and the constant terms are different, then the equation has no solutions.

2x + 9 + 3x + x  = _x +_

6x + 9 = _x + _

6x + 9 = 6x + 1

2)

To find the missing number, compare both sides of the equation. If the variable terms are the different and the constant terms are either different or same, then the equation has one solution.

2x + 9 + 3x + x = _x + _

6x + 9 = _x + _

6x + 9 = 3x + 3

3)

When equation is true for every possible value of x.

To find the missing number, compare both sides of the equation. If the variable terms are the same and the constant terms are same, then the equation has no solutions.

2x + 9 + 3x + x = _x + _

6x + 9 = _x + _

6x + 9 = 6x + 9

6x = 6x +9 -9

6x = 6x

6x/6 = x

x = x

Answer:

The two real solutions are [tex]x=\frac{12}{18} = 0.6667[/tex]  and [tex]x=-\frac{12}{18} =-0.6667[/tex]

Step-by-step explanation:

The equation [tex]9x^{2} -4=0[/tex] is a quadratic function of the form [tex]ax^{2} +bx+c=0[/tex] that can be solved by using the Quadratic Formula.

[tex]x=\frac{-b±\sqrt{b^{2} -4ac} }{2a}[/tex]

The plus and minus mean that the equation has two solution.

In order to identify is the equation has two real solutions we use the discriminant equation [tex]b^{2} -4ac[/tex]. Depending of the result we got:

1. If the discriminant is positive, we get two real solutions.

2. if the discriminant is negative, we get complex solutions.

3. If the discriminant is zero, we get just one solution.

Solution:

The equation [tex]9x^{2} -4=0[/tex] has a=9, b=0, and c=-4

Using the discriminant equation to know if the quadratic equation has two real solutions:

[tex]b^{2} -4ac[/tex]

[tex]0^{2} -4(9)(-4)=144[/tex] The discriminant is positive which mean we get two real solutions.

Using the Quadratic Formula

[tex]x=\frac{-b±\sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]x=\frac{-0±\sqrt{0^{2} -4(9)(-4)} }{2(9)}[/tex]

[tex]x=\frac{±\sqrt{144} }{18}[/tex]

[tex]x=±\frac{12}{18}[/tex]

then

[tex]x=\frac{12}{18} = 0.6667[/tex]  and [tex]x=-\frac{12}{18} =-0.6667[/tex]

To solve the equation 9x^2-4=0, we simplify and take the square root of both sides, resulting in two real solutions: x = 2/3 and x = -2/3.

To find two real solutions to the equation 9x^2-4=0, we can approach this by simplifying it into a form that can use the square root method for solving. Here are the steps:

Therefore, the two real solutions are x = 2/3 and x = -2/3.

Answer:

8 or 8.5

Step-by-step explanation:

27 divided by 2 = 13.5

13.5 take away 5 = 8.5

The age of Jari now if the age after 5 years doubles is 11.

Given that:

Five years after jari's age now doubles, he will be 27.

Let x be the age of Jari now.

An equation can be formed with the given information.

When the age doubles, the age is 2x.

Five years after this age can be written as 2x + 5.

Now, it is given that this age is 27.

So,

2x + 5 = 27

Subtract both sides by 5.

2x = 27 - 5

2x = 22

Divide both sides by 2.

x = 22/2 = 11

Hence Jari is now 11 years old.

Answer:

400mL/3l

Is the correct answer

Step-by-step explanation:

To find the quotient of 6 liters by 27 liters and 600 milliliters, convert both to milliliters and divide. The quotient is approximately 0.21739.

To find the quotient of 6 liters (L) divided by 27 liters and 600 milliliters (mL), we first need to convert the amounts to the same unit. Since there are 1,000 milliliters in a liter, we can convert 27 liters into milliliters:

27 L × 1,000 mL/L = 27,000 mL

Now we add the 600 mL:

27,000 mL + 600 mL = 27,600 mL

Rewrite the problem with both measurements in milliliters:

6,000 mL / 27,600 mL

We now divide 6,000 by 27,600:

6,000 mL / 27,600 mL = 0.21739 (rounded to five decimal places)

So, the quotient is approximately 0.21739.

If 1 cm represents 117 Km.

Then, 85.26 cm represents 117×85.26=9975.42 Km

therefore, the given places are 9975.42 Km apart from eachother.

The distance between Washington, D.C., and Baghdad, Iraq, are approximately 9,764.82 km apart in real life.

The scale factor states the scale or measurement by which a figure is bigger or smaller than the other figure. The size by which the figure would be reduced or enlarged is called its scale factor.

We are given that;

11cm=117km

Distance of baghdad and iraq= 85.26cm

Now,

If the scale on a map is 1 cm for every 117 km and Washington, D.C., and Baghdad, Iraq, are 85.26 cm apart on the map, then we can use the scale to find the actual distance between the two cities.

We can set up a proportion to solve for the actual distance:

1 cm / 117 km = 85.26 cm / x

To solve for x, we can cross-multiply:

1 * x = 117 * 85.26

x = 9,764.82 km

Therefore, by the scale factor the answer will be 9,764.82 km.

A dilation with a scale factor greater than 1 and then a translation is correct.

Dilation of a figure will leave its sides to get scaled (multiplied) by the same number. That number is called the scale factor of that dilation.

Its also called scaling of a figure, but due to the involvement of coordinates, it involves a center of a dilation, which is like a pinned point that stays at the same place after dilation.

Answer:

[tex]x^2 + y^2 =18[/tex]

Step-by-step explanation:

The standard equation of a circumference has the following formula.

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

Where the point (h, k) is the center of the circle and r is the radius.

If in this case we know that the circle has center at point (0,0), then its equation will have the following form

[tex]x ^ 2 + y ^ 2 = r ^ 2[/tex]

The radius of the circumference will be the distance from the center of the circumference to the point where the circumference is tangent to the line [tex]Ax + Bx + C = 0[/tex]

The radio is:

[tex]r=\frac{|Ah + Bk +C|}{\sqrt{A^2+B^2}}[/tex]

In this case, the line is

[tex]x + y = 6[/tex]

And the center of the circumference is (0, 0)

So

[tex]A = 1\\B = 1\\C = -6\\h = 0\\k = 0[/tex]

The radio is:

[tex]r=\frac{|1*0 + 1*0 -6|}{\sqrt{1^2+1^2}}\\\\r=\frac{|-6|}{\sqrt{1^2+1^2}}\\\\r=\frac{6}{\sqrt{2}}[/tex]

Finally the equation of the circumference is:

[tex]x^2 + y^2 =(\frac{6}{\sqrt{2}})^2\\\\x^2 + y^2 =18[/tex]

Final answer:

The standard form equation of the circle centered at (0, 0) and tangent to the line x + y = 6 is x² + y² = 18, after determining the radius using the distance formula.

Explanation:

The question asks for the standard form equation of a circle centered at (0, 0) that is tangent to the line x + y = 6. To find the standard form of the circle, we first need to determine the radius of the circle, which is equal to the distance from the center of the circle to the tangent line. Since the center of the circle is at the origin (0,0), we can use the distance formula for a point to a line:

d = |Ax + By + C| / √(A² + B²), where A, B, and C are the coefficients from the line equation Ax + By + C = 0.

In this case, the line x + y = 6 can be rewritten as x + y - 6 = 0 (A = 1, B = 1, C = -6). Plugging these into the distance formula we get:

d = |1 · 0 + 1 · 0 - 6| / √(1² + 1²) = 6 / √2 which simplifies to √18.

The standard form equation of a circle with center at (h, k) and radius r is (x - h)² + (y - k)² = r². With a center at (0, 0) and a radius of √18, the equation becomes:

x² + y² = 18.

This is the standard form equation of the circle which is tangent to the line x + y = 6 at one point.
