Since you dont know how many individual songs he wrote, we will represent that as x. Now, to find the total amount spent on buying "x" individual songs, you would have to multiply that by the 1.29$ it costs. Therefore, with the inclusion of the 9.99$ from the album, your equation is:

50 = 1.29x + 9.99

xeze [42]

Answer:

Step-by-step explanation:

The interest earned on the investment is the difference between the end-of-year value and the initial value:

$83.20 -80 = $3.20 . . . . simple interest per year

The interest rate is the ratio of this to the initial investment:

$3.20/$80.00 = 0.04 = 4% . . . . . simple interest rate per year

If -1 is one of the roots of the equation 3x² - 2k - 2x - 1 = 0, find the value of k.

snow_tiger [21]

Answer:

k = 2

Step-by-step explanation:

Given that x = - 1 is a root of the equation, then it satisfies the equation.

Substitute x = - 1 into the equation and solve for k, that is

3(- 1)² - 2k - 2(- 1) - 1 = 0

3 - 2k + 2 - 1 = 0

- 2k + 4 = 0 ( subtract 4 from both sides )

- 2k = - 4 ( divide both sides by - 2 )

k = 2

The parking space shown on the right has an area of 216 ft². A custom truck has rectangular dimensions of 12.1 ft by 3.6 ft. Can

mart [117]

Answer:

• Yes, the area of the truck is less than the area of the parking space.

• The missing dimension of the parking space is 12 ft.

Explanation:

The area of the parking space = 216 ft²

Part A

The dimensions of the custom truck = 12.1 ft by 3.6 ft.

To determine if the truck can fit into the space, we calculate the area of the truck.

$\begin{gathered} \text{Area of the truck}=12.1\times3.6 \\ =43.56ft^2 \end{gathered}$

Since the area of the truck is less than the area of the parking space, the truck will fit into the space.

Part B

The parking space is in the shape of a parallelogram.

$\text{Area of a parallelogram=Base x Perpendicular Height}$

Given:

• Area = 216 ft²

• Base = b ft

• Perpendicular Height = 18 ft

We then have:

$\begin{gathered} 216=b\times18 \\ 18b=216 \\ b=\frac{216}{18} \\ b=12\text{ ft} \end{gathered}$

The missing dimension of the parking space is 12 feet.
