Answer:

y= 155.45 cm

Explanation:

To solve this, we will need to use the Law of Sines

This states that:

$\frac{a}{sinA} =\frac{b}{sinB}$

Firstly, we need to find the sin of angle y. As this is a 30-60-90 right triangle, we know that the angle must be 60 degrees

Now that we have side x, the angle X, and the angle Y, we can solve for the side y using the Law of Sines

Lets plug in our known values into the equation

$\frac{89.75}{sin(30)} =\frac{y}{sin(60)}$

Next we can solve for y

$\frac{89.75sin(60)}{sin(30)} =y$

When plugged into a calculator, you get the value of 155.45 cm for side y

Answer:

Free enterprise systems, refers to an economy where

the market determines prices, products, and services

rather than the government. In other words, businesses

and services are free of government control. As the

statement mentions it allows the supply and demand of

consumers to determine the success or failure of a

business. We can grab for example Steve Jobs, one

of the creators of the multi-billion company called

Apple. An economy where enterprises are forced to

follow the government rules, tend to limit

themselves to provide just the necessary. On the other

hand, if a business goes to the free market it opens

a whole new world of possibilities. When apple first

appeared in the market it wasn't very popular, but

then started growing popularity with its products

and slogans. Apple needed to become a free enterprise

business for it to become what it is now. Without

rules or restrictions, businesses could grow much more;

but always taking to detail that the supply and demand

will be the changing factor of success or failure.

The most likely toxic chemicals that is found in baby bottles is called BPA. If high doses of this chemical is consumed, it might shut down the response system of estrogen in the babies. It could also possibly change the babies ability of producing ordinary thyroid hormones.

Law makers can address this possibility by making a law that bans the creation of a baby bottles plastic that contains these toxic chemicals. This provides with a strict interpretation of the precautionary principle because it is ‘banning’ all the bottles plastic that contains toxic chemicals. Banning is a strict interpretation.

Law makers can also make a law that limits the doses of this toxic chemical that can be found in the bottles plastic. This is a strict interpretation because there is a limit, and if the producers go above the limit, there is consequences to face.
