This is an interesting question. I chose to tackle it using the Law of Cosines.
AC² = AB² + BC² - 2·AB·BC·cos(B)
AM² = AB² + MB² - 2·AB·MB·cos(B)
Subtracting twice the second equation from the first, we have
AC² - 2·AM² = -AB² + BC² - 2·MB²
We know that MB = BC/2. When we substitute the given information, we have
8² - 2·3² = -4² + BC² - BC²/2
124 = BC² . . . . . . . . . . . . . . . . . . add 16, multiply by 2
2√31 = BC ≈ 11.1355
104=3m-50 is the equation that I would use, because 104 is the total, and it’s 3 dollars per mile, and $50 of the total is the initial fee. Sorry if the explanation isn’t the best, I’m kinda bad at them haha. Good luck!
Answer:
Hi! Your answer would be 34.
Step-by-step explanation:
Okay, so 40% off of $85 would be $51. Subtracting $85 and $51 gives you $34.
Answer: (should be) A
Step-by-step explanation: I've done the same test before
