Angle C is inscribed in circle O. AB is a diameter of circle O. What is the radius of circle O?

vova2212 [387]

Answer:

radius = 5 units

Step-by-step explanation:

leg lengths of 6 and 8

AC = 6

BC = 8

Notice that since AB = diameter of circle and that C is inscribed in circle O

angle C = 90 degrees

triangle ABC is a right triangle

(AB )^2 = (AC)^2 + (BC)^2 by Pythagorean theorem

so

(AB)^2 = 6^2 + 8^2 = 36 + 64 = 100

AB = square root of 100 = 10

so AO = (1/2) *AB = (1/2)*10 = 5

x * 0.04 = <span>$1,823.94
x = </span><span>$1,823.94 / 0.04
x = $45,598.50

20 is what percent of 50?

djverab [1.8K]

We can rephrase the question as "What percent of 50 is 20?".
"What percent ..." is an unknown. We'll use the variable x to represent this unknown.

The word 'of' in mathematics can mean 'multiply'. Likewise the word 'is' can mean 'equal'.

Now we have the phrase "20 equals to x times 50".

Or in an equation: 20 = x * 50

Solve for x.

20 = x * 50
$\frac{20}{50}$ = x <-- Divide both sides by 50

Simplify the fraction.

$\frac{20}{50} = \frac{2}{5}$

Convert the fraction into a decimal.

$\frac{2}{5}$ = 0.4

Convert the decimal into a percent.

0.4 = 40%

So, 40% is the answer.
