Good day sir hopefully you reply as this video was awhile ago but for #25 I used the area of a circle and equalled it to what they gave us in the question as the area of the shaded region ( pier^2=36pie -18) and solved for R and then i got the same answer when i worked the perimeter

For numbre 18, pay attention to what is being asked . You don't need to do all the calculation since when you add both equations gives you 3x+y = 15. That is your answer.

Hey, I really appreciate your work. I took the same test and came to review my answers. I have a question regarding question 37, the number I had some trouble with. Do you think there is some type of error in question as it does not specify until what decimal we have to round up like usual?

[@justforsat6647]

Thank you for this great video, but in question 18 you could have just added the 2 equations and you were going to get the solution.

[@6025nena]

Easier way to do 25 would be that since we know that the area of the square is 18 we can square root the 18 to get the side of 1 side. And then you just multiple that side by 4 to get the perimeter.

[@ScalarLearning]

That's a great suggestion, thank you!

[@Dovanieee]

how come for 6 the probability isn't 0.5

[@JohanLanting]

because in the first sentence it says that it is an unfair coin that makes the probability of landing on heads 0.6.

As Johan mentioned, the question states that it is unfair so it doesn't have an equal (0.5) chance of landing on heads. Thank you for watching!

hi, i got 13 wrongs on the math section of this exam, i guessed it means 650 or something, right? can someone tell me please if that is correct?

[@mthedon8649]

For question 13 I'm not clear on the formula you used after you got the slope

[@jacob8782]

So for question number 31, the question asks "How many indicated that they do not like comedies?" it isn't asking for a fraction but the entire problem is about fractions. so, instead of saying 80, couldn't I say 1/3 as in 1/3 of those surveyed don't like comedies. the answer key doesn't have 1/3, so im confused why that's wrong because the question doesn't specify how to write the number

[@ScalarLearning]

It says "how many," not what fraction or percentage, so we need a concrete number. Make sense?

[@bradenurso9812]

How did you notice the subtracting the square in the equation for number 25? Were there other ways to go about it?

[@OverclockingCowboy]

The area of the shaded region is given as 36pi - 18. Since the shaded area is equal to the circle area minus the square area, you can “speculate” that 36pi (is the circle) and 18 (is the square). To quickly verify: 36 pi = pi r(r) which gives you r = 6. Given that r=6, the square area becomes (1/2)(6)(6) = 18. The square area is confirmed. You can now calculate the perimeter.

[@OverclockingCowboy]

You can also just go ahead and calculate the shaded area (circle - square) pi (r)(r) - (1/2)(r)(r) = 36 pi - 18 (r)(r) = (36pi - 18) / (pi - 1/2) = 18(2pi - 1) / 1/2(2pi-1) = 36 From which we have r = 6. You can now compute the perimeter.

[@OverclockingCowboy]

He set up a table between price/meal and number of meals. As the price goes up by $4, number of meals drops by 80 (same as an increase of $0.50 leads to decrease in 10 meals). Then, he calculated the total sale for each price. TABLE for price, number of meals, total sale $12. 400. $4800 $16. 320. $5120 $20. 240. $4800 etc $16 gives the highest total sale.

[@OverclockingCowboy]

There is no quadratic equation. He was just thinking out loud. You are better off creating a small table just like he did. If you like equations, they look like M = 400 - (10/0.50) (P-12) where M = number of meals, 0

[@successparody]

Thank you so much. I really appreciate what you do. Could you please explain how I can solve number 14 using quadratic?

[@mister_sheesh]

(12+0.5x)(400-10x)

[@franciscopham5586]

Mister Sheesh is right. Here is my reasoning: sales = price * meals S = (12 + 0.5x)(400 - 10x)= -5x^2 + 80x + 4800 where x is the number of $0.50 price hikes that decreases the number of meals sold by 10 for each price hike. S = -5(x-8)^2 + 5120 in vertex form. The number price hikes to maximize the sales is 8. The price for maximum sales is 12 + 8 = $20 for $5120 in sales.

[@franciscopham1841]

@@franciscopham5586 8 price hikes at $0.50 each is $4 dollars more than $12. The answer should be $16.

Why D can't be the answer on q no 22? If angle BAC is equal to the angle EDF, it satisfies the AAA congruency rule. Why won't we choose it?

[@chalimatipa6787]

I think it’s because we already established the angle as 97. So they are asking for another reason why and the definition of congruency should be like same size and shape so we know they are the same shape because the angles are the same but the size (length) being equal makes it congruent. I think D would make them similar triangles but not congruent Idk idk if that made sense 😅😅

For problem 14, if you wanted to set up a quadratic, how would you do that? Or is it easier to just plug in the answer values (that's how I did it but I was wondering if a quadratic would be easier) Update: 780 math! Thanks!

[@OverclockingCowboy]

You need an equation for total sale that relates price/meal and number of meals. Then you have to find the price that maximizes the total sale. You also have to figure out what your constraints are. For example, you start with 400 meals. That is very time consuming. Just create a small table just like he did. Drop the number of meals by 80 starting from 400 for each increment in price of $4.
