Answer:

The current is approximately 8.571 Amps

Step-by-step explanation:

You are supposed to use Ohm's Law for this problem.

Recall that Ohm's Law gives you the relationship between voltage applied (V), resistance (R) and current (I):

$V=I\,*\,R$

If the units of resistance are ohms, and the voltage is in volts, the current will be given in Amps (amperes). Then solving for the current (I) in the above equation:

$I=\frac{V}{R} \\I=\frac{120}{14} \\I=8.571\,\,Amps$

Answer:

if you want to factorise it answer will be : (x+y)^2 - 4^2

and if you have to expand it anwer will be x^2 + y^2 + 2xy -16

Chicago is home to 2.706 million people and the city sees approximately 55 million visitors each year. China has a population of

Norma-Jean [14]

China could expect a quantity of visitors of 8.512 × 10⁶ in Chicago.

<h3>How to apply direct proportions</h3>

A <em>direct</em> proportion is a <em>direct</em> relationship between two variables, which in this case is represented between the quantity of tourists in the city of Chicago and the population of the country of origin.

Let suppose the existence of direct proportionality and world has a population of 9000 million people, the quantity of Chinese visitors in the city of Chicago is determined by the following formula:

x = (1.393 × 10⁹ / 9 × 10⁹) × 55 × 10⁶

x = 8.512 × 10⁶

China could expect a quantity of visitors of 8.512 × 10⁶ in Chicago. $\blacksquare$
