S = sale price (in dollars)
p = sticker price (in dollars)
Note: the sticker price is what the customer pays after the discount
Another note: This is ignoring any taxes or other fees
We're told that the sale price is the result of taking 10% off the sticker price. This means...
sale price = (sticker price) - (10% of sticker price)
s = p - 0.10*p
s = 1*p - 0.10*p
s = (1 - 0.10)*p
s = (0.90)*p
s = 0.90*p
So the expression for the sale price is 0.90*p where p is the sticker price in dollars.
Note: this means that the sale price is 90% of the sticker price.
----------------------------------------
Now plug in the sticker price p = 80 to find the sale price s
s = 0.90*p
s = 0.90*80
s = 72
The sale price is $72 which is what the customer will pay (if we ignore any taxes or other fees).
Answer:
All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1440 degrees (from above)... And there are ten angles... So, the measure of the angle of a regular decagon is 144 degrees.
Step-by-step explanation:
Answer:
add all of the sides
Step-by-step explanation:
Basically, we're multiplying 27 by 8 1/3.
1. 27 = 27/1
2. 8 1/3 = 8 * 3 = 24 + 1 = 25/3
3.27/1 * 25/3 = 27 * 25 = 675/3
4.675 divided by 3 = 225
Answer: 225 miles.
