**math**

You have a 1/6 chance of a 6 on each roll, 1/6*1/6=1/36 chance of rolling two in a roll. Making it a very rare chance

**math**

find the LCD, which is 24 and multiply each fraction to get to the LCD 2/3----> 18/24 5/8----> 15/24 now add them 18+15 = 33 so you get 33/24

1. both eukaryotic 2. some proteins in the cells are similar 3. share many genes in common hope thats what you were looking for

OMG what is with my typing today 1, of course, is C im sorry

**Grammar**

a and b

**algebra**

make everything into twelfths, so you have... 9/12k-2/12 =6/12 take out the 2/12 so... 9/12k=8/12 so now you divide 8/12 by 9/12 = 8/12*12/9 = 96/108 and simplify to 8/9 so k = 8/9

**Science**

well... its still clear, that's your problem you won't "see" it because you can't really see depth using a light microscope and of course its transparent.

**Science**

cytoplasm is essentially a clear liquid that holds everything in place since it's transparent, logically speaking if you just shine light through it (and dont stain it or anything) you wont see it

**MATH**

zero! when you multiply by five, you'll always get a number ending in 0 or 5. multiplying by two means if you get one ending in 5, it gets timesed by 2 and equals zero anyways try it with any number

**math**

the answer is 10squareroot 3. 25 root 24 simplifies to 50 root 6, then you divide the 50 by 5 and the root 6 by root 2 to get 10 root 3. hope that's clear enough

**MATH grade 10**

so basically you have a circle, right? and the equation of a circle is x^2+y^2 = r^2 so in this case your r, or radius is root of 64, or 8 if the radius of the circle is 8, use the formula for circumference of a circle (c=2pi(r)) to find the length of fencing so... c=2pi(8) so...

**Math 11**

a parabola on a graph opens upwards if the "a" value in y=a(x+b)^2+c is positive. If "a" is negative, it opens downwards. in the example it would open down, because the "a" value is negative

**math**

yes

**chemistry**

ahhh crud sorry i forgot about the % of H2O2 go with DrBob

**chemistry**

so basically since you have 250ml of solution, therefore you have 250g of H2O2 (i think you might have put in a typo)... now you calculate number of moles of H2O2 (the molar mass is approx 34 g/mol) with the formula number of moles = mass/molar mass now use mole ratios to find...

Best story i've had to read in school. The meaning i took from it is that AIs and "thinking machines" are more human in their behavior than we assume them to be example: the teaching machine hates its job and feels its talents are wasted on teaching grade 6 english

**Math**

This is a hard one. What helps me is to read each part of the problem carefully. Write the numbers you think on a piece of paper. When you find out if it is wrong put an x next to it. This will narrow down the process.

**Algebra**

What bob said is right. you do y2 - y1 _______ x2 - x1 That is a fraction (-1,-6) are the y's and (3,-2) are the x's. -1 is y1 and -6 is y2. and the same goes for the x's.
