Answer:
$342.30
Step-by-step explanation:
The original price of the computer is $489. The computer is discounted 30%, which means that 30% of the price is removed from the original price.
30% of 489 is
489 * 0.3 which is $146.7
146.7 is the discounted amount, not the selling price. To find the selling price, subtract how much is discounted ( 146.7) from the original price (489).
489-146.7= 342.3
If it goes from a higher number to a lower number it is a decrease.
(15,295 - 9182) / 15295....x 100
6113 / 15295 = 0.399....x 100 = 39.9% decrease
The name of the longest chord in a circle is called a diameter
Note that both 121 and 289 are perfect fractions: 121 = 11^2 and 289 = 17^2.
Thus,
121 11^2
------- = ---------- = (11/17)^2.
289 17^2
The square root of this is merely 11/17.
