1,2,4,8,16,32,64,128

Steps:

Divide the decimal number by 16. Treat the division as an integer division.

Write down the remainder (in hexadecimal).

Divide the result again by 16. Treat the division as an integer division.

Repeat step 2 and 3 until result is 0.

The hex value is the digit sequence of the remainders from the last to first.

Then multiply the answer by 100

74x-56=58(x-23)

74x-56=58x-1334

16x=1278

x=79.875

im blind

sos, my fualt

ive changed my answer and ignore the other post

You are right, 12% is indeed 0.12.

However for the percentage increase you add this to 1 to make 1.12

So...

x=initial

x*1.12=26.88

Therefore x=26.88

                     ........

                    1.12

Answer:£24.00

Lol, useful.

and no, im not spanish

im just taking it for my GCSE so i cn kind of understand it

For breakfast you prepare soluble coffee 600 ml of water (1000 ml = 1000 g water) at 92 ° C. If you take 200 ml in a cup, to which you add 25 g of water at 15 ° C to lower its temperature:
What is the final temperature of coffee? It considers that the specific heat is the same for water and brewed coffee.
The remaining 400 ml of the empty brewed coffee in a thermos and as has cooled a little while acctually now has a temperature of 89 ° C. At noon, when you take your coffee at lunch you realize that you have the same temperature. Why the temperature of the brewed coffee in the thermos remained?
Who wins heat?
What is the magnitude of the gain?
What is the temperature of the thermal equilibrium?

You cannot solve this as it is not an equation, however you can simplify it. 

x+x+48 will become 2x+48

The recurring symbol is a small dot on top of the number that will go on for ever

If it is a pattern of numbers that are constantly repeating then the dot will be on the first number of the sequence and the last number

Pythagoras theorem: a^2 + b^2= c^2

Where c is the hypotenuse.

You can also have: c^2-a^2=b^2

BODMAS- There fore you will do the division first, then the multiplication

22/2=11

11*36=396

7q-11=-10q

You then - 7q from both sides

-11=-17q

Then you divide by -17 to get: 

q=11/17

alleles are a type of gene

oh yeah...

didnt realise, i dnt normally put units :(

To subtract binomials, follow the same rules as with numbers, provided that the terms are alike. When terms contain the same variable and same exponent, they are like terms.
