Answer:

The rules of a contest say that there is a 9% chance of winning a prize. Six hundred people enter the contest. Predict how many people will win a prize?

9/100 x 600= 54

Step-by-step explanation:

From the above analogy, it shows that 9% of the entire 600 people will win the prize of the contest. this means that out of 600 people 54 people has the chance to clinch the medal while 546 has the remaining percentage

​Quadrilateral ABCD​ is inscribed in this circle.
murzikaleks [220]

Answer:

C = 80

Step-by-step explanation:

A cyclic quadrilateral is one where all 4 vertices touch the circumference of a circle.

It has 1 interesting property that should concern you: <B + <D = 180 degrees.

3x - 59 + 2x - 1 = 180          Combine like terms

5x - 60  = 180                     Add 60 to both sides.

5x = 180 + 60

5x = 240

x = 240/5

x = 48

Now go to 2x + 4.

x = 48

A = 2*48 + 4

A = 96 + 4

A = 100

So C = 180 - 100

C = 80

What is theformula for finding the hight of a 30-60-90 degree triangle
miv72 [106K]
We don't know which side your triangle is sitting on, so the 'height'
could be any one of three values.

Here are the two simple tools that tell you everything you want to
know about a 30°-60°-90° triangle.  These are worth memorizing:

-- The side opposite the 30° angle is 1/2 of the hypotenuse.

-- The side opposite the 60° angle is 1/2 of the hypotenuse times √3 .

I memorized them exactly 60 years ago.  They've been very useful,
and as far as I know, they haven't changed.
