Ok here is the problem:

One night, the King couldnt sleep, so he went down into the kitchen, where he found a bowl of mangoes. Being hungry, he took 1/6 of the mangoes. Later that same night, the queen was hungry and found the mangoes and took 1/5 of what the king had left. Still later, the first prince awoke, went to the kitchen, and ate 1/4 of the remaining mangoes. Even later, his brother, the second prince, ate 1/3 of what was left. Finally, the third prince ate 1/2 of what was left, leaving only three mangoes for the servants. How many mangoes were originally in the bowl?
Someone please help me figure this out!!
Thanks!

1). The vertices of a triangle are located at X(-2, -1), Y(2,5) and Z(4,3). What is the perimeter of this triangle? Round to the nearest tenth.

2). What is the perimeter of a square whose vertices are A(-4,-3), B(-5,1), C(-1,2), and D(0,-2)?

can anyone explain these two questions to me...i have no idea how to slove them...maybe i need to use distance formula?

What makes it itch so much? And what causes it to swell when you scratch it?
This is not asking what you do to stop it itching, nor how to take care of it. I want to know the science behind it.

Body A of mass 3kg has a velocity of +4ms^-1 and collides head on with body B, which has a mass of 2kg and a velocity of -2ms^-1. After the collision the velocity of B is found to be +3ms^-1.

What is the velocity of A after the collision?
What is the loss in kinetic energy of the bodies as a result of the collision?

You know Luna (earths moon) controls the tides and helps us have 24 hour days right. Well what if a very Large asteroid say like 4 Vesta gets caught into earths orbit wouldn't that cause serious Issues on earth.

Use the product rule to find the derivative.

f(x) = (x^2 - 2x + 2)(2x^3 - x^2 + 5)


if you could explain this problem step by step it would help thank you.

We know the series whose terms are the inverses of the primes diverges.

Now, let p_n be the prime of order 2n -1, that is
p_1 = 2
p_2 = 5
p_3 = 7,
p_4 = 11, and so on

Then, does Sum (n=1, oo) 1/(p_n) converge or diverge?

Thank you
