No problem. I was glad to help. If my answer was helpful you can "thumbs up" my answer.

thank you!

First we need to convert the percent to a decimal by dividing it into 100: $${\frac{{\mathtt{80}}}{{\mathtt{100}}}} = {\frac{{\mathtt{4}}}{{\mathtt{5}}}} = {\mathtt{0.8}}$$ Next we multiply that by 100, since "of" means multiplication: $${\frac{{\mathtt{80}}}{{\mathtt{100}}}}{\mathtt{\,\times\,}}{\mathtt{200}} = {\mathtt{160}}$$. If the answer has to be a fraction, put it over 1: $${\frac{{\mathtt{160}}}{{\mathtt{1}}}}$$

I wouldn't know. I don't go counting hair on mens heads.

First we subtract: 6min 13sec - 6min 5sec = 8 seconds.

Next we put that in fraction over our original time: 8sec / 6min 13sec

    Then we need like terms: Since 1min = 60sec, we multiply it by 60. 6min * 60sec = 360sec + 13sec = 373sec

This equals: $${\frac{{\mathtt{8}}}{{\mathtt{373}}}} = {\mathtt{0.021\: \!447\: \!721\: \!179\: \!624\: \!7}}$$ which round down to 0.02. We multiply it by 100 (percent are out of 100), and we get approximately 2%, because it's not exact.

What you are trying to find are factors less than 24 that multiply evenly to make 36.

The way you can find the factors of a number is to make a t-chart:

_____

1  | 36

2  | 18

3  | 12

4  |  9

6  |  6

Each line of numbers multiplys to make 36. Example: 1 * 36 = 36, 2 * 18 =36, 3 * 12 = 36, etc...

The question is asking use for sets that do not have numbers larger than 24. So our possible choices are:

12 rows of 3 children,

9 rows of 4 children,

6 rows of 6 children.

Y = 84730.86

I assume 5% interest is out of $50... so that is 5% of $50 or 5% x $50.

5% can be turned into .05, because percent are numbers out of 100, and $${\frac{{\mathtt{5}}}{{\mathtt{100}}}} = {\frac{{\mathtt{1}}}{{\mathtt{20}}}} = {\mathtt{0.05}}$$.

Then we multiply 0.05 by 50: $${\mathtt{0.05}}{\mathtt{\,\times\,}}{\mathtt{50}} = {\frac{{\mathtt{5}}}{{\mathtt{2}}}} = {\mathtt{2.5}}$$

Our final step is adding that to our orugunal total: $${\mathtt{50}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2.5}} = {\frac{{\mathtt{105}}}{{\mathtt{2}}}} = {\mathtt{52.5}}$$

$52.50.

$${\frac{{{\mathtt{n}}}^{{\mathtt{2}}}}{{\mathtt{n}}}}$$ = $${\frac{{\mathtt{n}}{\mathtt{\,\times\,}}{\mathtt{n}}}{{\mathtt{n}}}}$$ Then you take n from the top and bottom, and it simplifies to $${\mathtt{n}}$$.

Manly being swamped with so many problems from my teacher. It's only Math 60 level graphing, so it's not too hard, there's just so much of it. Any tips on getting a million (give or take a few) problems done quickly?

By "answer", I assume you mean solving for x or y.

8x + y = -16 can be anything, because there are two variables. To be able to simplify and get an answer, there can only be one.

What are you having trouble with?

4x / 3 = 7 /15       we can just cross-multiply this and solve

4x * (15) = 3 * 7

60x = 21          divide both sides by 60

x =  [21 / 60 ]   =   7 x 3] /  [20 x 3 ]    =  7 /20

Isn't the question asking the probability if only two numbers were picked? As in: Two numbers are picked in total, not two by each?

'Hi' is a way of life for extroverts.

Since it is a division problem, multiply by the reciprocal:

Factored:  [ (2x - 3)(2x + 3) ] / (2x + 5) · [ (2x + 5)(2x - 5) ] / [ (2x - 3)(2x - 3) ]

Numerator:      (2x - 3)(2x + 3)(2x + 5)(2x - 5)

Denominator:  (2x + 5)(2x - 3)(2x - 3)

Cancel:                 [ (2x + 3)(2x - 5) ] / (2x - 3) 

If were considering positive integers, we have

1, 4, 9, 16, 25, 36
