Answer:

video game: $29.50

DVD: $10

Step-by-step explanation:

Let d = price of one DVD, and let v = price of 1 video game.

"A bundle of two video games and three DVDS can be purchased for $89.00."

2v + 3d = 89

"A bundle of one video game and two DVDS can be purchased for $49.50."

v + 2d = 49.5

We have two equations in two unknowns, so we can solve them as a system of 2 equations.

2v + 3d = 89

v + 2d = 49.5

Rewrite the first equation.

Multiply both sides of the second equation by -2 and write it below the first equation.

Add the equations.

       2v + 3d = 89

(+)   -2v - 4d = -99

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

               -d = -10

d = 10

Now we substitute 10 for d in the second original equation and solve for v.

v + 2d = 49.5

v + 2(10) = 49.5

v + 20 = 49.5

v = 29.5

Answer: video game: $29.50; DVD: $10

This figure represents the base of a fish tank that is 8 inches high.
Igoryamba

The volume of the fish tank is 408 in³

To solve the volume of the fish tank, we need to understand what is the volume of plane shapes.

<h3>What is the volume of plane shapes?</h3>

The volume of plane shapes resembles a 3-dimensional space showing the area enclosed by the shape.

From the figure given:

The figure can be differentiated into two shapes;

  • A rectangle
  • A triangle

The volume of the rectangle is known as:

  • = Length × Breadth
  • = 7 inches × 6 inches
  • = 42 inches²

The volume of the triangle is:

  • = 1/2 × base × height
  • = 1/2 × 3 × 6
  • = 9 inches²

The total volume of the base of the fish tank now is:

  • = 42 inches² + 9 inches²
  • = 51 inches²

Now, the volume of the fish tank is:

  • = Height × base of the fish tank
  • = 8 inches × 51 inches²
  • = 408 in³

Answer:

a_n=\frac{1}{2}a_{n-1}

Step-by-step explanation:

Here, you can see every consecutive term is divided by 2. I think that's pretty obvious looking at it, but you can work it out like this if you'd like to. Divide each consecutive term by the one before it:

6\div12=\frac{1}{2}\\\\3\div6=\frac{1}{2}\\\\\frac{3}{2}\div3=\frac{1}{2}

Each term is multiplied by 1/2 over the last, or divided by 2. In this case actually, we do want it in the form of "multiplied by 1/2", as the recursive equation is:

a_n=xa_{n-1}

where x is the factor. Here, we're multiplying by x, so we want "multiplied by 1/2" as described above. x is 1/2, so you can write the equation:

a_n=\frac{1}{2}a_{n-1}

You can simply interpret this as "each term is 1/2 of the term before it"
