Find the value of x.
Alik [6]

Answer:

x =15

Step-by-step explanation:

In \odot D, AB and AC are chords which are equidistant from the center of the circle.

\therefore Chord \: AB \cong Chord\: AC

\therefore m \widehat {AB} = m\widehat {AC}

(Equal chords intercept equal arcs)

\because m \widehat {AB} = (10x-23)\degree

\therefore m \widehat {AC} = (10x-23)\degree

m \widehat {AB} +m \widehat {AC} +106\degree = 360\degree

(Arc sum postulate of a circle)

(10x-23)\degree + (10x-23)\degree= 360\degree- 106\degree

2(10x-23)\degree = 254\degree

(10x-23)\degree = 127\degree

10x-23 = 127

10x = 127+23

10x = 150

x = \frac {150}{10}

x =15

What is 25% Of 30% Of 400?
marta [7]

Answer:

25% of 30% of 400 = 30

33% decrease in value

Step-by-step explanation:

You can either get 30% of 400 first then 25% of 400 or you can get the total percentage of 400.

Method 1:

30% of 400 = 0.3 of 400 = 0.3 * 400 = 120

25% of 120 = .25 of 120 = .25 * 120 = 30

Method 2:

30% of 25% = 0.3 * 0.25 = 0.075 = 7.5% of 400

7.5% of 400 = 0.075 of 400 = 0.075 * 400 = 30

5.) To find the percentage  of the new price, you can build the equation below.

\frac{new price}{original price} = \frac{percent}{100}

\frac{200,000}{300,000}  = \frac{x}{100}

20,000,000 = 300,000x

x = 66.667

The percentage decrease in price is then 100% of the original price - 66.667% of the original price = 100% - 66.67% = 33.33% = 33% decrease.
