Answer:

Correct option is D $\frac{P}{(0.8)(1.08)}$

Step-by-step explanation:

Let the laptop's original cost be = L

After 20% discount its price will be (100 - 20)% × L = 0.8L

8% sales tax on this price = (100 + 8)% × 0.8L = 1.08 × 0.8L

So, p = 1.08 × 0.8L

⇒ L = $\frac{p}{(0.8)(1.08)}$

2) At the store Julie bought a shirt for $23.97, which was 25% off the original price. Which of these should she use to find x,

Scrat [10]

Answer:

0.75x = 23.97

Step-by-step explanation:

The total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75.

What is the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth?

LuckyWell [14K]

Answer:

The length of the pendulum is 14.13 meters.

Step-by-step explanation:

The length of a pendulum is given by the formula, $T = 2\pi \sqrt{\frac{L}{g} }$ , where T is the times period and L is the length of the pendulum.

Now, given that T = 2.4π seconds.

So, from the above equation, we get,

$2.4\pi = 2\pi \sqrt{\frac{L}{g} }$

⇒ $\sqrt{\frac{L}{g}} = 1.2$

⇒ $\frac{L}{g} = 1.44$ {We have the value of g as 9.81 m/sec²}

⇒ L = 1.44 × 9.81 = 14.13 meters. (Approx.)

Therefore, the length of the pendulum is 14.13 meters. (Answer)
