[ASMR] Solving Your Maths Problems

My bad everyone! The Volume question (47:48) the volume of the cone SHOULD be ⅓ π 3² 15 = 45π. Thus the total volume being = 540π - 45π = 395π (1225.22cm³)

Man 4*(5/7)=20/7, not 33/7… that exercise is 100% wrong( dividing fraction)

[@newdlz7552]

@@claudiobianco1059 You're stupid, 4 5/7=4+5/7, not 4×5/7. You solve a mixed number by making it an improper fraction, you do this byultiplying thr whole number by the denominator (bottom number), adding it to the numerator (top number) and then putting the number over the original denominator, so, 4 5/7=([4×7]+5)/7=33/7

As someone who is rather terrible at math (and perhaps not the most fond of it) it's still always a treasure to see people who love it just have fun and really get into what they're passionate about. Super calming too, I often play this video when I have my own homework to settle with. Cheers Dido!

I already struggle with math, and it’s worse if the teacher can’t teach or is mean 🤷🏾 but this was super relaxing and it made me realize struggling is ok and you just need nice and good people to help you. So thank you dido for the math lesson!

[@dennisgroeschel610]

Dido its been a month since the last card magic video, I used to watch them religiously and get excited for them every monday. Please make a new one soon!!

[@xevento8682]

The problem at 37:44 (Edit: Check the comments to know why what I wrote here is incorrect) It takes 15 mph for the first mile therefore the overall average is 15/1=15 it takes x mph for the second mile therefore the overall average is (15 + x)/2 = 30 mph Solve for x 15+x = 60 x = 45 Therefore the car needs to drive 45mph the whole second mile to average 30mph overall

[@mrfishy9909]

I like your funny words magic man

[@jan0906]

Actually Dido is right. When you travel 30 mph, you travel 0,5 miles per minute. Then you need 4 minutes for the 2 miles. The speed on the first mile is 15 mph so 0,25 miles per minute. This means after four minutes you are on the top of the hill and to get an average of 30 mph you need to be at the end of the 2. mile at the same time which is impossible Even if you travel 45 mph on the second mile you end up tarveling 5 min and 20 sec (4min+1 1/3min) which is an average speed of 22,5 mph (60 min / ([5 1/3] min / 2 miles))

just a suggestion, instead of derivating the tan 4 times, I find a little bit easier to write tan as the derivative of -ln(cos(x)), which has the same formula (after the first order) but log and cos are quite simple to remember

[@_krook_]

Thank you so much for solving my equation! I was having so much trouble with it. :D

[@DidoASMR]

You’re welcome 😁 Thanks for submitting!

[@2ayski127]

which one was it

[@anthonyruffeno1082]

For the average speed of the car problem: Total trip 2 miles First mile avg speed = 15mph = x 2nd mile avg speed = solve = y Final avg speed after 2 miles = 30 mph Equation: (x+y)/2 = 30 (15+y)/2=30 15+y=60 Y=45 The car had to travel on average at 45 mph on the 2nd mile to have a total avg of 30 mph throughout the 2 mile trip Don’t think the problem had anything to do with time

[@keano_rl]

this is wrong since if the car is travelling at 45mph, it does so for a shorter time (as it is travelling the same distance at a greater speed), meaning the average speed of this leg of the journey has a lesser effect on the total average speed. Dido's solution is correct.

[@NotAwesomeGabe]

@@keano_rl What does time have to do with this question? Are you just making something up for the sake of it or something? The question is how many mph to get an average of 30 mph in a 2 mile trip. Are you telling me if I go 15 miles per hour for one mile, then go 45 miles per hour for a mile, it won't equal 30mph for 2 miles?

[@keano_rl]

@@NotAwesomeGabe well that’s the thing since let’s say you go 15 mph in the first leg and it takes you an hour for example, and then you go 45 mph in the second leg, that leg will clearly not take an hour since it is the same distance but you’re travelling faster so in this case the second leg only takes 20 minutes. Now the total distance you have travelled is 30 miles and the total time it toile was 80 minutes = 4/3 hours so the average speed of the journey would be 30/(4/3)=22.5 mph but by your logic the answer would have been 30 mph. The reason your answer is incorrect is because the car is travelling at 45mph for a SHORTER period of time as it travels the SAME distance at a FASTER speed and hence it has a LESSER effect on the AVERAGE speed of the journey.

[@batesyboy321]

[@Grigio-KenCarsonsVer.]

@@DidoASMR omg you actually replied 😳. Love your content

[@NotAwesomeGabe]

Thanks for the video Dido! I did notice you must have misunderstood the Speed, Distance, Time question. The answer would be 45mph, since for the first mile you go 15mph, if you were to go another mile at 45mph, it would average out to 30mph. I don't know where you got the time part from but time to sleep to the rest of the video ;)

[@trevorholloway6180]

For the volume problem, the volume of the cone should have a radius of 3 not 6 as computed for the volume of the cylinder.

[@pieter6220]

I believe the second problem is wrong. 4*(5/7)=20/7 and 5*(8/12)=40/12=10/3 so (20/7)/(10/3)=(20/7)*(3/10)=60/70=6/7

[@Bronzescorpion]

You are mistaken here, because we are dealing with mixed numbers. Bear with me, it is difficult to write the math in a comment, but mixed numbers e.g. 4½ are different from multiplying a whole number with a fraction e.g. 4*½. The former means four whole and a half, which as an improper fraction would be 9/2. The latter means four times a half, which equals to 2. You did the later example, where Dido did the correct former example.

[@Bronzescorpion]

@@UnPandaOrange You are right that normally no sign is the same as having a multiplication sign, but mixed numbers i.e. a whole number and a fraction, is the exception to the rule. So if done properly you should always use a multiplication sign in cases like these to avoid mix up with mixed numbers.

[@ash3rrblx244]

the first problem (a fun starter problem) is actually 66. for number 1 its 99 divided by 3 which is 33. so then for number 2 its 165 divided by 33 which is 5. then number 3 and its 5 plus (?) equals 7 and with basic math is 2 so 2 balls equal 2 then man plus man (number 4) is 66 times 1 ball which is 1 so its basically 66 x 1 which equals 66. 1 man = 33 1 glove = 5 1 ball = 1

[@NotAwesomeGabe]

You are wrong. Number 2 is a ball and glove.

[@NotAwesomeGabe]

and the man has a ball in his eye on the last part, how did you miss that he literally said it?

Dido, in your expand and simplify, wouldn't you divide the entire equation by 2? Leaving you with 5x²+16xy+12y²?

Well if you were to divide by 2 you would be left with a completely different equation. What you’ve written is not the same as (5x+6y)(2x+4y). If that makes sense?

[@robertdering8969]

I don't know If I didn't understand the question "Speed, distance, time" right, but isn't just 15 mph on the first half and It needs top be 45 mph on the Seconds half, because (15+45)/2 makes 30 mph on average for two miles?

[@Av21795]

If anyone can answer please comment Basically I have a question about the first problem. I agree that man is 33, but in the next equation it says that man times glove is 165. Therefore if you did division you would get glove is 5. After that you can say that since glove is 5, ball has to be 1 if the third equation is true, so that makes the final answer 66. Man- 33 Glove- 5 Ball- 1 ?=66 How did dido get 107?

Math makes me sleep, good idea 10/10

[@sabachekk5610]

I know I’m late to this, but I think the first problem is a little flawed. When we assume that the man with his eye as a ball is m+b, we technically aren’t considering that we subtracted his eye and added the ball. So to be exact, the man with the ball as his eye should be m+b-eye. But if we had added this variable, the problem would’ve been impossible to solve, thus I think this problem is incomplete.

I want to mention the mistake in the baseball math problem. Because one man is 33 one glove is 5 and there are 2 balls wich represents 2 but in the final problem there is only one ball so that means it is a trick problem. Also forgot to mention that the last problem is: Man+Man with glove (38) x Ball (1) and if you count it correctly you'll get 71

[@NotAwesomeGabe]

nope, you got tricked. The glove had a ball in it so instead of Man x Glove = 165 like you solved, it was Man x (Glove+Ball)= 165

The car would need to drive for 4 minutes at 45mph to average 30mph, which would be an additional 3 miles. Limiting it to the next mile doesn't leave enough time for it to be possible. If it was 2.1 miles or 29.9 mph, you'd have to go very fast, but it would be possible.
