Anita has a spherical balloon that has a diameter of 4 inches. Alaina has a spherical balloon that holds twice as much air as Anita's balloon. What is the diameter of Alaina's balloon?

The solution for n of the expression in this problem is given as follows:

n = 5.

With the application of the distributive property, the outer term multiplies each of the inner terms of the expression. If possible, these inner terms than can be added or subtracted combining the like terms.

The mistake in the solution was applying the distributive property to 3(2n - 7), as 3 has to multiply both terms, 2n and -7, hence:

3(2n - 7) = 6n - 21.

Thus the solution to the expression is obtained as follows:

6n - 21 = 9

6n = 30

n = 30/6

n = 5.

The square of the expression 1/2 is given as the numeric value in the terms of the 0.7071.

The value that a number yields when multiplied by itself is known as the square root of the number. The square root is denoted by the radical sign. For example, 16 minus 4 is 16. The root symbol or radicals is another name for the radical symbol. If an integer is a perfect square, we can quickly determine its square root.

square root of the 1/2 = √1/2

We can use this rule for radicals to write the expression.

√a/b = √a/√b

So, by multiplying by the right form of 1, we may rationalise the denominator or, in other words, remove the radical from the denominator:

√1/2 x √2/√2

√2/2

1.4142/2

0.7071

So the square of the 1/2 is 0.7071.

107+73 = 180

107-73 = 34

========================================================

Explanation

Rule: Supplementary angles always add to 180 degrees.

This is our system of equations.

[tex]\begin{cases}x+y = 180\\x-y = 34\\\end{cases}[/tex]

Add the equations straight down.

After the y terms go away, we have this new equation: 2x = 214 which solves to x = 107 after dividing both sides by 2.

Then use this x value to find y

x+y = 180

107+y = 180

y = 180-107

y = 73

Or you could say

x-y = 34

107-y = 34

-y = 34-107

-y = -73

y = 73

Either way, we get the same y value each time. This helps confirm the answer.

Another way to confirm the answer is shown in the next section below.

---------------------

Check:

x+y = 180

107+73 = 180

180 = 180 .... confirms the 1st equation

x-y = 34

107-73 = 34

34 = 34 ... the other equation is confirmed.

We can convert the unit kg/m ³ to  g/cm³ by using the formula Kg/m³ = 10⁻³ g/cm³.

We are provided with the unit kg/m ³ that means Kilograms per meter cube.

We have to covert it into g/cm³.

Now, we know, from the standard conversion rates that one kilograms is equal to 1000 grams and one meter cube is roughly equal to 10⁶ centimeter cubes.

So, if we want to do the unit conversion, we should write,

= g/cm³

= 1000/1000000 g/cm³

Kg/m³ = 10⁻³ g/cm³.

Now, the above mentioned relation is our formula for the conversion of the two unit.

So, now we can write that, one kilograms per meter cube is equal to 10⁻³ grams per centimeter cubes.

Therefore , the solution of the given problem of equation comes out to be y can be either 3 +√(6) or 3 -√(6) for FG to be equal to HI.

In arithmetic equations, the similar symbol (=) is used to denote equivalence between two statements. It is demonstrated that utilising mathematical methods, which have acted as manifestations of reality, it is feasible to compare different numerical factors. The equal sign, for instance, splits the number 12 and even the answer y + 6 = 12 into two separate parts. One can compute how many characters are already present on either end of this symbol. Contradictory symbol meanings are common.

Here,

To find y such that FG = HI, we need to first calculate FG and HI and then set them equal to each other.

The distance formula can be used to calculate the distance between two points:

Distance between F and G:

FG = √(((-4) - (-5))² + ((-4) - (-7))²)

FG = √(1² + 3²)

FG = √(10)

Distance between H and I:

HI = √((y - 3)² + (10 - 8)²)

HI = √((y - 3)² + 4)

Now we set FG equal to HI:

√(10) = √((y - 3)² + 4)

10 = (y - 3)² + 4

6 = (y - 3)²

y - 3 = ±√(6)

y = 3 ±√(6)

Therefore, y can be either 3 +√(6) or 3 -√(6) for FG to be equal to HI.

Therefore , the solution of the given problem of triangle comes out to be ∠ADC  = 100 and ∠DCB  = 39 Degree.

Given that they have three quadrants or more, triangles are considered polygons. It has a straightforward geometric shape. The letters ABC form a right-angled triangle when put together. Euclidean geometry creates a new rectangle of square when the borders are incompatible. Given that they have three sides and three corners, triangles are categorised as polygons. The corners of a triangle are determined by where its three sides meet. The sum of the angles inside a triangle is 180 degrees.

Here,

Given :

A triangle ADC and Triangle DCB

To find the angle :∠ADC and ∠DCB in the figure

So,

Acc to triangle angle sum property:

43 + 3y + 7 + 2x + 17 = 180

Simplifying, we get:

2x + 3y + 67 = 180

Subtracting 67 from both sides, we get:

2x + 3y = 113

and

61 + 3y - 13 + 4x - 1 = 180

4x + 3y + 47 = 180

4x + 3y = 133

2x + 3y = 113

4x + 3y = 133

-4x - 6y = -226

Adding this to the second equation, we get:

-3y = -93

Dividing both sides by -3, we get:

y = 31

Substituting this value of y into either equation, we can solve for x:

2x + 3(31) = 113

2x + 93 = 113

2x = 20

x = 10

Therefore, the solution is x = 10, y = 31.

Thus,

∠ADC  = 3(31) + 7 = 93 + 7  = 100

∠DCB = 4(10) -1 = 40 -1  =39

What is function ?

Function can be defined in which it relates an input to output.

To simplify f(x) + g(x) where f(x) = 3x + 2 and g(x) = 4x, we can simply add the two functions by adding their corresponding terms. Therefore, f(x) + g(x) = 3x + 2 + 4x = 7x + 2.

To simplify the function f(g(x)), we would first substitute g(x) into the expression for f(x) wherever x appears, giving f(g(x)) = 3(g(x)) + 2

Then, we would substitute the expression for g(x), which is 4x, into the expression for f(g(x)), giving f(g(x)) = 3(4x) + 2 = 12x + 2.

Combining functions can be useful in many situations, such as in physics or engineering where multiple variables or parameters are involved in a single equation. It can also be useful in finance or economics where the behavior of multiple factors needs to be modeled in a single function.
