from a vine but 9+10=19 but on vine case 21

 do this to make it minus 52 to -52

1:15 i think

It should be 2

it depends on whether it's in a linear relationship 

more info required

 I think y then should = 2

Well, JB, you just need to multiply 52 times 7 + 5/6  =  52 x 47/6

Write back if you have trouble.......

That depends on which dimensions 3.5 and 2 are 

the formula is

Area= base x perpendicular height.

Note that the language is confusing.......

If the plant grew 100% of its original size, it would have doubled in size

If it grew 200% of its original size it would have tripled in size

So, 250% of its original size would mean the plant grew 3 + 1/2 times its original size....

8    .

Don't feel too stupid......I don't see the "trick," either......maybe there is some "identity" of which we are unaware....!!!

It got 2 and a half times bigger and you can draw the plant. :)

You should explain how do do it happy7.  OR don't give the answer and tell them where the calculator is.  :)

$$150\div5$$

Hi Chris,

I am looking forward to Geno response   LOL

Maybe there is some 'obvious' method.  But it will make me feel less stupid if you can't 'see' it either,  :))

( |6-8| )-1)² / 6 + 8 =

( l -2 l  - 1 )² /6 + 8 =

(2 - 1)² / 6 + 8 =

1² / 6 + 8 = 

1 / 6 + 8 =

49 / 6

This is a statistics question happy,  but I too am not sure if there is enough info given. 

You just need 3 numbers that multiply together to give 70

None can be  bigger than 10cm

Hint: the factors of 70 (less than or equal to 10) are 1,2,5,7,10

Yeah....the way geno came up with that answer is a "sin"

40 divided by 5 is 8.

Yes that is probably it.

You passed the audition with flying colours  

NOW GENO - I know I am a real expert at making a mountain out of an mole hill BUT how did you do it with no working?   

$$\\sin 105 - sin 15\\
=sin(180-105)-sin15\\
=sin75-sin15\\
=cos15-sin15\\
=cos(45-30)-sin(45-30)\\
=cos45cos30+sin45sin30-[sin45cos30-cos45sin30]\\
=sin45cos30+sin45sin30-sin45cos30+cos45sin30\\
=sin45sin30+sin45sin30\\
=2sin45sin30\\
=2\times\frac{1}{\sqrt2}\times\frac{1}{2}\\
=2\times\frac{1}{\sqrt2}\times\frac{1}{2}\\
=\frac{1}{\sqrt2}\\
=\frac{\sqrt2}{2}\\$$

@CPhill Thanks a lot for all the other help! =) I really appriciate it!

No......there is nothing to simplify.....

Just "plug" each separate "x" value into (-4/3)x - 3  and find y at that x value

I'll get you started...for x = 6, we have  (-4/3)(6) - 3   = ( -8 - 3 ) = 11 = "y"
