its a simple cross product,...i think

5/20=3/x

x=3(20)/5

x=12 

it'll take 12min to cut it into 3 equal pieces :)

Post your problem and we'll see what we can do.....

Here's another method :

Length of a side  = sqrt(6^2 + 18^2)  = sqrt (36 + 324)  = sqrt (360) 

And using the Law of Cosines, we can find the smaller interior angle of the rhombus

12^2  = 360 + 360 - 2(360)cos(theta)

[144 - 360 - 360]  / [ -2(360)]  = cos (theta)

cos-1  [ [144 - 360 - 360]  / [ -2(360] ]  = theta  = 36.869897645844°

Using the Law of Sines.....we can find the height - h - as follows :

sqrt(360)   = h / sin(36.869897645844°)

h = sqrt(360)* sin (36.869897645844°)  =  11.3841995766061656  cm

Here's a pic :  [DE  is the height]

im in pre algebra

2 and could you stop i need help

with? I am in 1st yeay Calculus II

under the equal sign there is a drop down list saying "create graph" click on that and you should be able have 2 plots on the same graph

is this a challenge or do you need help?

2(9x+7)=3/4x+9

2(9x+7)-3/4x-9=0

18x+14-3/4x-9=0

18x-3/4x=9-14

72/4x-3/4x=-5

69/4x=-5

x=20/69

x≈0.2898550724637681

An integer is any number that is whole, the sign doesn't matter. Example: \(...-2,-1,0,1,2...\)

1/4=15^x+2

1/4-2=15^x+2-2

-7/4=15^x

to bring any exponant down we use ln, so;

ln(-7/4)=xln(15)

ln(-7/4)/ln(15)=x

hope it helped

pretty much a number that isnt imaginary.

It's 2.. Once again stop asking these stupid questions and grow up please

can you not spam, some people really need help

if you're solving for t

then, 

-7(t-8)=0

-7(t-8)/-7=0/-7

t-8=0

t-8+8=0+8

t=8

Hello Mistress Katie-Leigh,

I'd sometimes use the two words slightly differently.

A cuddle to me can be more casual, and more likely to be quicker.  To snuggle into someone is more intimate and will likely require more time.

You cuddle a person or animal or toy or whatever

but

you snuggle into something that is either bigger (more enveloping) or more intimate.  Like a big pet dog is you are cold, a partner if you are cold or feeling very affectionate, a parent (if you are a small child) or a comfort blanket if you are a baby.

ps, Could you please lock the school gates shortly?  Should be done as night will befall thee soon.  :/

94=y/4-18

94+18=y/4-18+18

112=y/4

112(4)=y/4(4)

448=y

9+10=19

oh, it could also be 21

all those numbers are whole number its a simple addition

So:

x=85

y=1530

w=218.571428571428571428...

if it's 0.1-0.9 it becomes 1/-9/10

if it's 0.01-0.99 it becomes 1/100-99/100

if it's 0.001-0.999 it becomes 1/1000-999/1000

annd so on

aslos 0.3repeating is 1/3 and 0.6repeating is 1/6

(2(x-4)=10)/2

(x-4=5)+4

x=9

Solve for x:
x^4-17 x^2+16 = 0

Substitute y = x^2:
y^2-17 y+16 = 0

The left hand side factors into a product with two terms:
(y-16) (y-1) = 0

Split into two equations:
y-16 = 0 or y-1 = 0

Add 16 to both sides:
y = 16 or y-1 = 0

Substitute back for y = x^2:
x^2 = 16 or y-1 = 0

Take the square root of both sides:
x = 4 or x = -4 or y-1 = 0

Add 1 to both sides:
x = 4 or x = -4 or y = 1

Substitute back for y = x^2:
x = 4 or x = -4 or x^2 = 1

Take the square root of both sides:
Answer: | x = 4   or x = -4   or x = 1   or x = -1

You first add 18 to both sides, getting 112=y/4. Then you multiply both sides by 4, getting 448=y. Switch it around, and you get y=448.

I think Alan must have missed the division sign......[no big deal.....  ]
