Answer:

Paul should give 18 teaspoons of medicine to his dog.

Step-by-step explanation:

It is stated in the question that for every 12 pounds, 3 teaspoons of medicine is to be given to the dog.

This implies that:

12 pounds = 3 teaspoons

1 pound = 3/12 teaspoons

= 1/4 teaspoons <em> ( by cross multiplication )</em>

<em />

<h3>72 pounds = 1/4 * 72 teaspoons</h3><h3> = 18 teaspoons</h3><h3 />

Hence, Paul should add 18 teaspoons of medicine to his dog's food.

A set of twins, Andrea and Courtney, are initially 10 years old. While Courtney remains on Earth, Andrea rides on a spaceship th

SVETLANKA909090 [29]

The initial age of 10 years and the spaceship speed of 0.60•c, gives the Andrea's age at the end of the trip as 18 years.

<h3>How can Andrea's new age be calculated?</h3>

The time dilation using the Lorentz transformation formula is presented as follows;

$t' = \frac{t}{ \sqrt{1 - \frac{ {v}^{2} }{ {c}^{2} } } }$

From the question, we have;

The spaceship's speed, <em>v</em> = 0.6•c

∆t = Rest frame, Courtney's time, change = 10 years

Therefore;

$\delta t' =\delta t \times \sqrt{1 - \frac{ {(0.6 \cdot c)}^{2} }{ {c}^{2} } } = 8$

The time that elapses as measured by Andrea = 8 years

Andrea's age, <em>A</em>, at the end of the trip is therefore;

A = 10 years + 8 years = 18 years

If two numbers round to the same number, does that mean the numbers are equal?
