You have 2\3 of a pizza left from yesterday. You divide it into 4 equal pieces. What fraction of the pizza is each piece?

Mrrafil [7]

Step-by-step explanation:

that means we divide 2/3 by 4.

2/3 / 4 = 2/3 / 4/1 = 2/3 × 1/4 = 2/12 = 1/6

so each quarter of the remaining 2/3 pizza is actually 1/6 of the complete pizza.

An angle is drawn in standard position passing through the unit circle at (0.643,0.766). The angle in standard position θ has a

<h2>Hello!</h2>

The asnwer is: Cos50° ≈ 0.643

A unit circle is a cirgle with a radius equal of 1, knowing that, also know the following:

The angle is drawn passing trough the unit circle at (0.643,0.766) it means that:

$x=0.643\\y=0.766$

So,

Cos50° ≈ 0.643

We can prove that by following the next steps:

- If it's a unit circle,here is a right triangle with hypotenuse of 1,

$1^{2}=x^{2}+y^{2}$

$1^{2}=0.643^{2}+0.766^{2}$

$1^{2}=0.4134 +0.5867$

$1=1.0001=1$

- We can determine the cosine of the angle by the following formula:

$cos(\alpha)=\frac{x}{hypotenuse} \\cos(\alpha)^{-1}=cos(\frac{0.643}{1})^{-1} \\\alpha=49.98$

Therefore,

Cos(α)=49.98°≈50°

Also, if there is a right triangle, according to the Pythagorean Thorem:

$1^{2}=(Cos(\alpha))^{2}+(Sin(\alpha))^{2} \\Cos(50)=\sqrt{1-(Sin(50))^{2}}=0.6427$

Hence,

Cos50° ≈ 0.643

Have a nice day!
