P.S. LOL

0.2136 x 1/3

= 0.0712

And calculators are your best friends.

Maths bless you.

Don't be confused with that parentheses. They just means multiplication.

48÷2(9+3) = 48÷2x12 = 288

0.7^x=0.2

x log 0.7 = log 0.2

x = log 0.2 / log 0.7 ≈ 4.512338026

2696/6

= 1348/3

= 449 1/3

449.3333...

9+3=12

48/2=24

24*12=288

It is 5555 upon 1 x 3 upon 2

which is 16665 upon 2 

which is 8332.5

A Quadratic EQUATION is generally of the form  ax^2 + bx + c = 0

The QUADRTIC FORMULA can be used to solve quadratic EQUATIONS in this form for 'x'

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

Break them up into their prime factors and take the common ones to get the HCF

32  =  2 x 2 x 2 x 2 x 2

40  =  2 x 2 x 2 x 5                 2 x 2 x 2  are common factors = 8

Seems we go through this every few weeks

(-4)^2 =16

-4^2  =  -(4^2) = -16    as explained by Alan

Do you mean something like the results of the following function:

f(n) = 10 + 1.1*n^2  where n runs from 1 to 30

what is 1.8915071e+19 in numbers with no e and +19 cause i don't understand?!? Please answer!^_^

1.8915071e+19. This number is a "computer-speak" for scientific notation. "e" in this context stands for "exponent" and "+" means that the exponent is "positive". The number can be written in a more familiar way thus:1.8915071e+19 =1.8915071 x 10^19 =18,915,071,000,000,000,000

What is the HCF of 32 and 40

the factors of 32 are   1,2,4,8,16 and 32

what is the largest of these that also goes into 40?

That will be the highest common factor :)

What is the remainder when 75 to power 75 to power 75 is divided by 37?

[75^75^75] mod 37 =1

(3/5)lb  / 1 bowl    =  10lbs / ?bowls        cross-multiply

?bowls* (3/5)  = 1 *10

?bowls * (3/5)  = 10      multiply both sides by 5/3

?bowls = 10 (5/3)   = 50/3 bowls = [16 + 2/3] bowls

Yur question does not make sense.    

dont know been told the same thing

pi is the ratio of the circumference to the diameter of a circle.

It is an irrational number, which means it cannot be expressed exactly as a ratio of two whole numbers (though 22/7 and 355/113 are approximations that are often used).  It also cannot be expressed exactly as a decimal because its decimal expansion is infinitely long (though 3.14 and the value given by Guest #1 are approximations).

.

(-4)^2 → (-4)*(-4)  → +16

But  -4^2  → -(4^2)  → -(4*4)  → -16   because exponentiation (raising to a power) takes precedence over negation.

Like so:

Nice answer Geno :)

Each element of S is a product of 5 consequtive numbers.  At least two of them are even, and one of those is a multiple of 4, so the product is a multiple of 2*4 = 8.  At least one of them is a multiple of 3.  Exactly one of them is a multiple of 5.  Therefore, each element of S is a multiple of 8*3*5 = 120.  The smallest element of S is 1*2*3*4*5 = 120.  GCD of all elements of S cannot be greater than that.  Thus, GCD of all elements of S is 120.

9+3=12

12 times 2 = 24

48 divide by 24 =2

Helo,

We are not here to do all your homework for you.  Just choose one question -post it - get you answer - say thank you and try to learn from it.  If you do nt understand then query the answer. 

Also you first question makes no sense.  How can an angle be measured in cm ??
