12! / 4!
= 1×2×3×4×5×6×7×8×9×10×11×12 / 1×2×3×4
= 5×6×7×8×9×10×11×12 = 19958400
Answer:
shipping and handling is <u>18.90</u> dollars
Step-by-step explanation:
percent means "per one hundred", so any percent can be written as a fraction over 100
30% = 30/100 = 0.30
Multiply 0.30 with the price 63 to get 0.30*63 = 18.90, which is the cost of shipping only. This result is added on top of the 63 dollars to get the total cost.
It has been awhile since I worked with in qualities but I got the answer,
-1/3 < or equal to p < or equal to 2.
I multiplied the 5 in the middle of the equation with what's in parentheses to get 15p - 10, then I added 10 to both outer sides of the equation and got
-5 < or equal to 15p < or equal to 30.
Then lastly I divided 15 by -5 and 30!
I hope that's right.. I'm sorry if it isn't!
