A CD usually sells for $14.00. If the CD is 20% off, and sales tax is 7%, what is the total price of the CD, including tax?

tankabanditka [31]

Answer:

the total price of the CD including tax is $11.984

Step-by-step explanation:

The computation of the total price of the CD including tax is shown below:

The Selling price of the CD is $14

CD is 20% off

And, the sales tax rate is 7%

So, the total price of the CD is

= ($14 - $14 × 20%) × (1.07)

= $11.2 × 1.07

= $11.984

Hence, the total price of the CD including tax is $11.984

Answer

$P(t) = 19100. e^{0.06t}$

b) P(8) =30866

Step-by-step explanation

Use formula:

$P(t) = P. e^{rt}$

Here, P = 19100

r = 6% = 0.06

$P(t) = 19100. e^{0.06t}$

b) t = 2008 - 2000 = 8

$P(8) = 19100. e^{0.06\times 8}$

$P(8) = 19100. e^{0.48}$

$P(8) = 19100\times 1.616\\\\P(8) = 30,865.6\\\\P(8) \approx 30,866$

Jude says that the volume of a square pyramid with base edges of 9.7 in and a height of 9 in is equal to the volume of a cylinde

earnstyle [38]

Answer:

The correct option is;

Yes, his calculations are correct and the volumes for figures are equal

Step-by-step explanation:

The volume, V, of a square (of side s) pyramid of height h = $\frac{1}{3} \times s^2 \times h$

Where:

s = 9.7 inches

h = 9 inches

We have;

$V = \frac{1}{3} \times 9.7^2 \times 9 = \frac{1}{3} \times 94.09 \times 9 = \frac{1}{3} \times 846.81 = 282.27 \approx 282 \ in^3$

The volume, $V_c$ , of a cylinder of radius r = Base area × Height, h = (π×r²)×h

Where:

Base area = π×r²

r = Radius of the cylinder = 5.47 inches

h = Height of the cylinder = 3 inches

$V_c$ = π × 5.47² × 3 = π × 29.9209 × 3 = π × 89.7627 = 281.998 ≈ 282 m³

Therefore, Jude is correct.
