1 1/8 is the answer

there are 18 moons,

rotates for 58 days, 15 hours and 30 minutes on Earth,

It takes Mercury about 59 Earth days to spin once on its axis (the rotation period), and about 88 Earth days to complete one orbit about the Sun. However, the length of the day on Mercury (sunrise to sunrise) is 176 Earth days.

Mercury is the smallest planet in our solar system -- only slightly larger than the Earth'smoon. It is the closest planet to the sun at a distance of about 58 million km (36 million miles) or 0.39 AU

Mercury's diameter is 1,516 miles (2,440 km), mass:328.5E21 kg (0.055 Earth mass)

a= 3/4b +0.23 and a= 0.65 what is the value of b?   .... so we have...

0.65 = (3/4)b + 0.23           subtract 0.23 to both sides

0.42  = (3/4)b                     multiply both sies by 4/3

(4/3)(0.42)  = b  = 0.56

I assume this is  

[cos 20 ] / 15       {otherwise, it doesn't make sense} =

about   .063

could you copy the question so i can see it

4x+5=2x-6

  +6      +6

4x+11=2x

-4x      -4x

(-1)11=-2x(-1)

-11= x

It's called an inditerminate form, because there is no defined value. (Don't believe me, then google it:)    )

Are you in kindergarden?!?! Seriously?

V. of cube= Length*width*hight

 15-x>12

-15    -15

(-1)-x> -3(-1)

x<3

x^5+5            x=-2

(-2)^5= -32+5= -27

14 / √2  = about 9.9

If  this equation is true, it's a right triangle....if not....it's not......

15^2   + 36^2   = 40^2  ?????

We have to also know the radius to answer this......

Let f(t) =  0.5 + 1.1e^0.01t

Then f '(t)  =   (.01)(1.1)e^(.01t) = .011e^(.01t)

It can be easly solved by using equivalent solving or however you call it in english language in my language (slovenian) it is ekvivalentne enačbe. Well, let's say a number is x. Then the equation looks like that:

x + 18 = 3x - 8

First, you need to put the parts with x on the left side, and the parts of equation without x on the right side. Important is, that when you move the part of equation from one side to another, it changes from - to +, or from + to -. Than, the equation looks like that:

x - 3x = -8 -18

Now calculate the left and the right part of the equation. If there is no number before x, than it means the number should be 1.

1x - 3x = -26

- 2x = -26

Now search for the x;

-2 x = -26

    x = -26 : (-2)

    x = 13

You work hard and never give up!

There are billions of digits of the first few.

Yep they're different.

For square : Base*Height

Triangle: Base*Height /2 

The answer is 0

Put the minus behind the number

It is about 22/7 = 3,14 (not exactly)
