[tex]36 cm^3[/tex] of pure alcoh ol must be added to the [tex]10 cm^3[/tex] of the 8% solution to obtain [tex]10 + 36 = 46 cm^3[/tex] of an 80% solution.

What is Algebraic expression ?

Algebraic expression can be defined as combination οf variables and constants

Let's first calculate the amount  of pure alcohol in the 8% solution:

Amount of pure alcohol = 8%  of [tex]10 cm^3 = 0.08 x 10 cm^3 = 0.8 cm^3[/tex]

N ow, let's  assume [tex]x cm^3[/tex]of pure alcohol must be added to the 10 cm^3 of the 8% solution to obtain a total volume of [tex]10 + x cm^3[/tex] of an 80% solution. The amount of pure alcohol in the final solution would be:

ο[tex](10 + x) cm^3 = 0.8 (10 + x) cm^3[/tex]

Since we started with [tex]0.8 cm^3[/tex]of pure alcohol and we want to end up with  

[tex]0.8 (10 + x) cm^3[/tex], we can set up the following equation:

[tex]0.8 + x = 0.8 (10 + x)[/tex]ο

Simplifying and solving for x, we get:

[tex]0.8 + x = 8 + 0.8x[/tex]

[tex]0.2x = 7.2[/tex]

[tex]x = 36[/tex]

Therefore, [tex]36 cm^3[/tex] of pure alcohol must be added to the [tex]10 cm^3[/tex]of the 8% solution to obtain [tex]10 + 36 = 46 cm^3[/tex] of an 80% solution.

Existence and uniqueness of solutions to systems of differential equations depend on the number of equations and the order of each equation. For example, a system of two first-order equations has a unique solution, while a system of three first-order equations may not have a unique solution.

Previously, we considered the scalar differential equation, which is a single differential equation involving only one independent variable. In this case, the solution to the equation is unique. This is because there is only one equation and only one variable, so the solution must be unique for a given set of initial conditions.

For a system of differential equations, the existence and uniqueness of solutions depend on the number of equations and the order of each equation.

Systems of differential equations with higher order equations or more equations than unknowns may not have a unique solution. On the other hand, if there are more unknowns than equations, then there is always a unique solution. To find the solution, the equations must be solved simultaneously.

In conclusion, A scalar differential equation always has a unique solution.

If a large diamond with a mass of 4289.6 grams was recently discovered in a mine and the density of the diamond is 3.51 grams over centimeters cubed, the volume is 1221.9 cm³.

To find the volume of the diamond, we need to use its mass and density. The density of the diamond is given as 3.51 grams per cubic centimeter. This means that every cubic centimeter of diamond has a mass of 3.51 grams.

We can use this information to find the volume of the diamond by dividing its mass by its density. Plugging in the given values, we get:

Volume = Mass / Density

Volume = 4289.6 g / 3.51 g/cm³

Volume = 1221.86 cm³

This means that the diamond has a volume of 1221.86 cubic centimeters. However, the question asks us to round the answer to the nearest hundredth, so we round this value to: Volume = 1221.9 cm³

Answer:

10. To find the area of rhombus ABCD, we can use the formula:

Area = (diagonal 1 x diagonal 2) / 2

We need to find the length of both diagonals. Since the diagonals of a rhombus are perpendicular and bisect each other, we can use the Pythagorean theorem to find the length of each diagonal.

AC is one diagonal, AB is a side of the rhombus, and BD is the other diagonal divided by 2 (since BD bisects AC):

BD = AC/2 = 10/2 = 5 cm

Using the Pythagorean theorem with AC and BD:

AC^2 = AB^2 + BD^2

AC^2 = 13^2 + 5^2

AC^2 = 169 + 25

AC^2 = 194

AC = sqrt(194) ≈ 13.93 cm

Now that we have the lengths of both diagonals:

Area = (AC x BD) / 2

    = (13.93 x 5) / 2

    ≈ 34.83 cm^2

Therefore, the area of rhombus ABCD is approximately 34.83 cm^2.

11. We know that the area of rhombus ABCD is 96 cm^2, and that BD is 8 cm. To find the length of AC, we can use the formula:

Area = (diagonal 1 x diagonal 2) / 2

Solving for diagonal 1 (AC):

AC = (2 x Area) / BD

  = (2 x 96) / 8

  = 24 cm

Therefore, the length of AC is 24 cm.

12. We know that AB is a side of the rhombus and that AB = 16 m. We also know that mZABD = 60 degrees. We can use trigonometry to find the length of the diagonals.

First, we can find the length of AD using the law of cosines:

AD^2 = AB^2 + BD^2 - 2(AB)(BD)cos(mZABD)

AD^2 = 16^2 + (2x)^2 - 2(16)(2x)cos(60)

AD^2 = 256 + 4 - 32x

AD^2 = 260 - 32x

AD = sqrt(260 - 32x)

Then, we can find the length of AC using the law of sines:

AC / sin(mZBAD) = AD / sin(mZABD)

AC / sin(120) = AD / sin(60)

AC = (AD x sin(120)) / sin(60)

AC = (sqrt(260 - 32x) x sqrt(3)) / 2

Now that we have the lengths of both diagonals:

Area = (AC x BD) / 2

    = [(sqrt(260 - 32x) x sqrt(3)) / 2] x 8 / 2

    = 2(sqrt(260 - 32x) x sqrt(3))

    ≈ 67.29 m^2

Therefore, the area of rhombus ABCD is approximately 67.29 square meters.

13. We know that the perimeter of the rhombus is 20 mm, so each side is 5 mm. We also know that AC is one of the diagonals. To find the length of the other diagonal, we can use the Pythagorean theorem.

Let x be half the length of the other diagonal:

AC^2 = (2x)^2 + 5^2

x^2 = (AC^2 - 25) / 4

x = sqrt((AC^2 - 25) / 4)

Now that we have the lengths of both diagonals:

Area = (AC x BD) / 2

    = (AC x 2x) / 2

    = xAC

    = sqrt((AC^2 - 25) / 4) x AC

    ≈ 19.80 mm^2

Therefore, the area of rhombus ABCD is approximately 19.80 square millimeters.

The exact value of sin−1(cos(1013​π)) is sin−1(1 / (2sin(1013π) - cos(1013π) + 1)).

To find the exact value of sin−1(cos(1013​π)), we need to use the identity sin^2(x) + cos^2(x) = 1. Since sin−1(cos(1013​π)) is an angle whose sine is cos(1013​π), we can let that angle be x: sin(x) = cos(1013π).Let's find the sine of x using the identity sin^2(x) + cos^2(x) = 1:sin^2(x) + cos^2(x) = 1sin^2(x) + (cos(1013π))^2 = 1sin^2(x) + cos^2(1013π) = 1sin^2(x) + sin^2(π/2 - 1013π) = 1Now we need to simplify sin^2(π/2 - 1013π):sin^2(π/2 - 1013π) = sin^2(π/2)cos^2(1013π) - 2sin(π/2)cos(1013π)sin(1013π/2) + sin^2(1013π/2)= 1(cos(1013π))^2 - 2sin(1013π/2)cos(1013π) + 0= cos^2(1013π) - 2sin(1013π)cos(1013π)= cos(1013π)(cos(1013π) - 2sin(1013π))Using the identity sin^2(x) + cos^2(x) = 1, we can rewrite sin^2(x) as 1 - cos^2(x):sin^2(x) + cos^2(x) = 11 - cos^2(x) + cos^2(1013π) = 11 - cos(1013π)(cos(1013π) - 2sin(1013π)) + cos^2(1013π) = 1cos(1013π) - cos(1013π)^2 + 2sin(1013π)cos(1013π) = 1cos(1013π) + cos(1013π)(2sin(1013π) - cos(1013π)) = 1cos(1013π)(2sin(1013π) - cos(1013π) + 1) = 1cos(1013π) = 1 / (2sin(1013π) - cos(1013π) + 1)Therefore, the exact value of sin−1(cos(1013​π)) is sin−1(1 / (2sin(1013π) - cos(1013π) + 1)).

Kayla would ultimately spend $210.91 + $14.76 = $225.67 for all the clothing items, including sales tax.

To determine if Kayla's budget will be enough to purchase all the clothing items listed after sales tax is applied, we need to calculate the total cost of the items first.

The cost of 2 T-shirts would be 2 x $9.98 = $19.96.

The cost of 3 dresses would be 3 x $24.99 = $74.97.

The cost of 1 pair of pants would be $25.99.

The cost of 1 pair of shoes would be $89.99.

Therefore, the total cost of the clothing items is $19.96 + $74.97 + $25.99 + $89.99 = $210.91.

Next, we need to add the sales tax rate of 7% to the total cost to find the final price that Kayla would pay.

7% of $210.91 = $14.76

Therefore, the final price that Kayla would pay for all the clothing items, including sales tax, is $210.91 + $14.76 = $225.67.
