Just divide and then compare the two:

Anna: 7 / 20 = 0.35 per meal.

Dana already has: 0.36 per meal.

So: 0.36 - 0.35 =0.01 - This is how much larger Dana's meal is compared to Anna's meal

From 1 to 9 =None
From 10 to 99 = 9
From 100 to 199 =20
From 200 to 999 =160
From 1000 to 1999 =300
From 2000 to 2001(inclusive) =5
Grand Total = 9 + 20 + 160 + 300 + 5 =494 zeros

P.S. If you don't want 2001 included, then:494 - 2 =492 zeros.

Here is the answer (Scroll down if you want to view it) 

(x-3)(x+3)/(x+3) limx-->-3 

cancel (x+3) with (x+3) 

we are left with (x-3) limx-->-3 

subsitute 

-3-3=-6 

Factor x^5 + x^4 + 1.

(x^2 + x + 1) (x^3 - x + 1)

The expression can't be factored. 

Unless,

x^5+x^4+1=0 

If it was like that, then we can factor it.

first subtract 1 

x^5+x^4=-1

Now factor x^4

which is: 

x^4(x+1)=-1

also equals

0=\(x^4(x+1)+1\)

sumfor(n, 45, 144, 1 / (sin n * sin (n+1))) = -1.511943134.....

∑[1/ [sin(n)*sin(n+1)], n, 45, 144] =-1.511943134.........

Jeesh learn how to do your own maths ok!!!!!!! 

It is not maths, but the best option here would be A- freedom since they are used here to portray " sunflower-bordered roads", though this could equally be as true for adventure, in the sense that a road will take you to an end destination. Both I would consider correct, though I feel B would be slightly easier to expand on if that is what you need to do.

Find 1/(sin 45 sin 46) + 1/(sin 47 sin 48) + ... + 1/(sin 133 sin 144).

\(=\frac{1}{ (sin 45 sin 46)} + \frac{1}{(sin 47 sin 48) }+ ..         . + \frac{1}{sin (180-133) sin (180-144))}\\ =\frac{1}{ (sin 45 sin 46)} + \frac{1}{(sin 47 sin 48) }+ ..         . + \frac{1}{sin (47) sin (46))}\\ =\frac{1}{ sin 45 sin 46} + \frac{1}{sin 46sin 47} + \frac{1}{sin 47 sin 48 }.....+ \frac{1}{sin89sin90}\\ \)

Yea, I know, that does not help much.

Ok so i cant help srry

So you are the self appointed police officer?

I do not mind people pointing out cheats but you have turned it into a full time job.

You do not do anything else here at all!

Don't you have some of your own study to do?

If someone told me to rotate something by 90 degrees I would not know that I was meant to go counter clockwise. 

I would ask "which direction?"

I have never heard of that 'standard' assumption before. 

Too late, I already answered. My answer is probably not right though.

If you know this person is cheating then perhaps you are in the same class.

Why don't you just dob Sinclairdragon into your teacher ?

I found 11.   There could be more but I can't see them.
