pie- use to eat

pi- Use the formula. The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.

it depends not what size the paper is and alot of other stuff

yes what is your questions?

Hi Melody,

It is nice to meet you too :)

I'm really sorry if I still don't understand.

I know that 560 is two times 280, but, could you explain to me how to get 280 and 400?

And for the graph, is it Cake A = 40 pcs, Cake B = 80 pcs, and Cake C = 0 pcs to get the maximum profit?

Thank you very much for your help.

KE=1/2 x m x v^2

KE=1/2 x 2.1 x 30^2

KE =945 Joules.

Hi Arshan,

It is nice to meet you :)

I've been puzzling over this questions.

It is late - I am making excuses for the fact that my logic may be totally wrong... BUT

I divided all the number by 25 just to make them smaller and easier to work with:

Since the sugar in the 3 cakes is in the ratio  3:2:1

and the sale price of each cake is in the ratio 6:4:2  

(The ratios are the same but dollars is twice as big as grams.)

The maximum amount of sugar is 280*25g

So the maximum sale price must be no more than $560*25 = $14000

I drew this graph to help me.  I used x y and z for the number of A,B and C cakes produced.

This is a right triangle> the string is the hypotenuse    the tree is one leg and the distance from you to the tree is the other leg.

 S-O-H  C-A-H  T-O-A        S-O-H   sin = opposite over hypotenuse  =  8/30

sin= 8/30

arcsin (8/30) = 15.47 degrees

You didn't tell us what  units  '.866025403784'  has...I will assume it is degrees

to convert to radians    :     degrees x pi/180 = radians = .015114995 radians

Hi Gabmilex :)

Guest one has given you an approximation. :)    Thanks guest1

but

-27/13 approx = -2.0769230769230769

\(\frac{-27}{13}=-2\frac{1}{13}\\=-2.\dot{0}7692\dot{3}\\=-2.\bar{0}\bar7\bar6\bar9\bar2\bar{3}\)

The last 2 are just showing the repeated digits but different countries do this differently.

This is 2 of the common methods :)

If 1/4 of the sweets are Toffees, then 3/4 are mints.

Let x= total sweets:     3/4 x = 21 mints     (solve for 'x')     then x = 21(4/3) = 28

How do you solve 100^-2/3

1/[10 x (10)^1/3] =0.046415888......

ANOTHER WAY:

Simplify the following:
100^(-2/3)

1/100^(2/3) = 1/(100^2)^(1/3) = 1/(10^4)^(1/3) = (1/10^(1/3))/(10):
(1/10^(1/3))/(10)

Rationalize the denominator. 1/(10 10^(1/3)) = 1/(10 10^(1/3))×(10^(2/3))/(10^(2/3)) = (10^(2/3))/(10×10):
(10^(2/3))/(10×10)

10×10 = 100:
Answer: |(10^(2/3))/(100)

-1 can be written as -3/3

take -3/3 -5/3

=   -8/3  

FV =15,000 [1 + 0.06/12]^5

FV =15,000[1 +.005]^5

FV =15,000 x 1.005^5

FV =15,000 x 1.025251253128125

FV =$15,378.77
