First, convert the 20% to a real mathematical number. For percents, this is always done by dividing the 20% by 100%, or 20% / 100% = 0.200.
Second, find out what 20% of $600.25 is. This is the amount of the sale discount. This is always found by mulitplying 0.200 by the item's cost $600.25, like this:
0.200 x $600.25 = $120.05.
So for this sale, you'll save $120.05 on this item.
This means, the cost of the item to you is
$600.25 - $120.05 = $480.20.
Alternatively, you can think about it this way. The item is 20% off. This means you'll pay 80.000% of the total cost (100% - 20% = 80.000%).
Now what's 80.000% of the total cost?
0.800 x $600.25 = $480.20.
Just like the result above, the sale price on the item is $480.20.
Hope this helps you on your assignment! :)
Answer:
Yes
Step-by-step explanation:
Permutation :
nPr = n! ÷ (n - r)!
nCr = n! ÷ (n-r)!r!
11 objects taken 3 at a time :
11P3 = 11! ÷ (11 - 3)!
11P3 = 11! / 8!
11P3 = (11 * 10 * 9 )
11P3 = 990
Dividing by 3!
3! = 3*2*1 = 6
= 990 / 6
= 165
For combination :
11C3 = 11! ÷ 8!3!
11C3 = (11 * 10 * 9) / (3 * 2 * 1)
11C3 = 990 / 6
11C3
Answer:
Each triangle has an area of 6 and the square in the middle has an area of 9.
6 times 4 is 24, plus 9 is 33. Therefore, your surface area is 33
Answer:
15%
Step-by-step explanation:
To calculate a percentage the formula we use is like this
(amount to calculate / total amount ) *100
in this case we are calculating what percentage is 12 miles of 80 miles so it would be
(12mi / 80mi )*100 = 15%
