Hi Jedithious, it is nice to meet you.

I personally do not care how many you submit so long as they are proper questions.

I would like people to be more interactive with the replies sometimes, they would learn better that way.
and it is good to have interaction.

Melody.

A cylinder of radius 4cm and height 6cm is recast into a cone which has a base radius equals to the height of the cylinder.Find the total surface area of the cone.

This question is not complete.
You could ask what the height of the cone is if all the cylinder is recast into the cone (perpendicular height or slant height)
Or you could ask, how much of the material is reused if the height is such and such.
But to find the surface area of the cone, assuming that it is not identical to the cylinder, is not possible unless you are given a height.

The surface area of the cylinder is 292.53cm squared (correct to 2 decimal places)

How would I simplify (1000^1/3)^1000^33.333...? I know it's too large a number to write in decimal notation, but how can it be written as 1000^x or 1000^1000^x?

(2^6)^4 = 2^6 * 2^6 * 2^6 * 2^6 = 2^24
hence
(2^a)^b = 2^(ab)
do you get where I am going here?

(2^6)^4^7 = 2^24^7 = 2^(24*7) or just 2^(6*4*7)

Now you can answer your own question,

91 is the answer

What is the procedure to solve a problem like this?
A number is palindromic, if it is the same backwards as forwards.
Of the largest palindrome made from the product of two two-digit numbers, find one of the numbers.
a) 92 b) 89 c) 90 d) 91
----------------------------------------------------------------------------

The biggest possible number is 99 times 92 = 9108
The first palindromic number less than 9108 is 9009
I tried 9009 divided by 89 and 9009 divided by 91
since 9009 is odd I knew the 2 even ones would not go into it

9009 divided by 91 = 99 exactly so
91 is the answer.

Multiply both sides by 5.6

First, we get the (1/3)-root of both sides of the equation, to get x = the (1/3)-root of 6. Getting the (1/3)-root is equivalent to cubing something (since 1/3^-1 = 3), so therefore x = 6^3. When you solve 6^3, you get 216, so x must equal 216.

The common denominator is 77. 1/11 becomes 7/77 , and 5/7 becomes 55/77 . Now we can add the numerators and keep the common denominator.
7/77 + 55/77 = 62/77 Answer

complete the square: y=x^2-6x+7

I am not certain of what you are bieing asked to do but this is what I would assume

subtract 7 off both sides
y-7 = x^2-6x

The x co-efficient is -6
(-6/2) ² = 3 ² = 9
add 9 to both sides

y-7+9 = x^2 - 6x +9

y+2 = (x-3) ²

Not sure but this is what I think

Part One = INT[SQRT(Plaintext)]
Part Two = Plaintext – {INT[SQRT(Plaintext)]}^2
-------------------------------------
If plain text = 28 then
sqrt28=5.29...
INT(5.29) = 5 (I assume INT stands for integer part)

28 - (5squared) = 3
--------------------------------------

If plaintext = 123456 then
sqrt123456 = 351.36...
INT(351.36..)=351

123456 - (351squared) = 255
--------------------------------------------

INT[SQRT(123456)]

=INT 351.36

=351

I am assuming int stands for integer

I think it would be proportionally quicker to bury more than 1 at a time.

Alleison123:
i need to solve for the given variable
(x,5) (4,11) and the given rate is 2/3

Okay I'm assuming by given rate you mean slope... In that case use the point-slope formula!

y-y1=m(x-x1)+b

m=slope,
b= y-intercept

Plug in the x,y coordinates to find:
y-11=(2/3)(x-4)+b
solve it to get in in standard form y=mx+b
After that, you can plug in the y to find x.

27 x 5/9 is telling you to multiply (27/1) x (5/9). So to multiple fractions, you multiply across the top, then the bottom. This equals 15 when reduced (135/9 after you get is fraction, you divide the top by the bottom)
49 / (7/10) is STAY CHANGE FLIP. The first number STAYs. The division sign CHANGEs to multiplication. The next fraction FLIPs. So really, this is (49/1) x (10/7) which equals 70 when reduced (490/7 is the unreduced fraction).
(3/8) of 32 is the same as (3/8) x 32. So this is just like the first one. I'll let you figure out this last one!

The cubic root of 8 is just asking what number multiplied by itself 3 times will give you 8; it happens to be 2.
9/4 is just an"improper" fraction. As a mixed number it equals 2 and 1/4 or just 2.25.
The square root of 5 is asking what number times itself gives you five. There is not exact number but it happens to be in between 2 and 3, closer to 2. Lets call it 2.23 ish
And 2.7 is 2.7
So from least to greatest the numbers go: 2, 2.23, 2.25, 2.7 (aka cube root of 8, square root of 5, 9/4, 2.7)
