help me with maths i got 5 minutes!

[evil^milk]

a truck enters a highway driving 60 mph. a car enters the highway at the same place 15 minutes later and drives 70 mph in the same direction. how long will it take the car to pass the truck?

(minutes)

the length of a rectangular mailing label is 4 centimeters less than twice the width. the perimiter is 58 centimeters. find the dimensions of the label.

the speed of a stream is 2 mph. A boat travels 12 miles upstream in the same time it takes to travel 16 miles downstream. what is the speed of the boat in still water?

 

[Parrot of doom]

Use your ****ing brain and do it yourself.

 

[evil^milk]

the palmyra triangle has a perimeter of 4400 miles. the side of the middle length is 2 times as long as the shortest side. the longest side is 4 times as long as the middle side. how long is each side?

 

[Insano]

You serious?

 

[Top Secret]

Dude, I did half of these in my head in less than a minute. Do it your ****ing self.

 

[Deleted member 56031]

do it yourself

 

[Tollbooth Willie]

Sex is the answer.

quick tell him he's only got 5 MINUTES!

 

[CyberPitz]

Is it bad I couldn't do one of these without serious thought? Damnit, I really need to get back to school.

 

[-Psy-]

55 minutes?

the car dont see a obstacle in the way and crash and dont come out

she put a wrong ingredient and creates a poisonous gas and die so zero

a grizzly bears attacks the boat and destroy it and the person dies

the palmyra triangle has a perimeter of 4400 miles. the side of the middle length is 2 times as long as the shortest side. the longest side is 4 times as long as the middle side. how long is each side?

a rectangle comes and pwnd them all so zero

there you go lazy ass

 

[-Psy-]

and the world divided by RJMC...I mean zero.

No, these all require a bit of thinking to wrap your head around, but they can for the most part be done mentally.

 

[Bad^Hat]

Where do I sign up to your class, professor RJMC? :O

 

[DEATHMASTER]

lol, you might've gotten real answers if there wasn't 5 min.s left

Weird, I never learned how to solve the 'car drives 100 km/h in direction blabla' problems manually, at least not that I can remember. I can just do it by plotting graphs and taking the point where the two graphs intersect.

Equation for the first car is:
y = (60/3.6)x + 15000 (16.6667 m/s - fuck the imperial system - and a lead start of 15000 meter)

Second:
y = (70/3.6)x

They intersect at x = 5400.

I think, been years since I've done linear equations.

 

[Azner]

I seem tobe able to do the speed question, but im not gonna help you since its past 5min

 

[Krynn72]

Next time you need maths help, just call 911.

You can just substitute one equation into the other than solver for x. It's the same thing.

iz okay evil milk, we is not dumb, math is dumb

I thank the higher powers that I don't have maths anymore.

Maths is fun, it's so easy if you know what you're doing
