If there are 41 blades of grass per square centimeter how many blades of grass would you have on a bit of land that is 4 square meters?

\(\begin{array}{rcll} 4\ m^2 &=& 4\ m^2 \cdot \frac{100\ cm}{1\ m}\cdot \frac{100\ cm}{1\ m}\\ &=& 40000\ cm^2\\\\ \frac{41\ \text{Blades of grass}}{ 1\ cm^2} \cdot 40000\ cm^2 &=& 41\cdot 40000 \quad \text{Blades of grass}\\ &=& 1640000 \quad \text{Blades of grass}\\ \end{array}\)

I'm not really sure... Would you find how many cm are in 1m, and then multiply that by 41???

Chris, why don't you let the kids interact with their answerers. The asker was logged on when I posted my answer. 

If this kid was intetested in learning I was there to guide the learning process.  Why did you overrule me and just give the answer. 

Solve the following system:

{13 y-5 x = -7 | (equation 1)

5 x+4 y = 24 | (equation 2)

Add equation 1 to equation 2:

{-(5 x)+13 y = -7 | (equation 1)

0 x+17 y = 17 | (equation 2)

Divide equation 2 by 17:

{-(5 x)+13 y = -7 | (equation 1)

0 x+y = 1 | (equation 2)

Subtract 13 × (equation 2) from equation 1:

{-(5 x)+0 y = -20 | (equation 1)

0 x+y = 1 | (equation 2)

Divide equation 1 by -5:

{x+0 y = 4 | (equation 1)

0 x+y = 1 | (equation 2)

Collect results:

Answer: |{x = 4          y=1

You are fortunate to have one. LOL!!!!

I'm ok with english or grammar, in fact, I'm pretty good at it.

Lol, haha... ;-;

Congrats hope u have fun i guess

Hahahaha lmao!

Nah, more like three weeks, by then the person is so fed up with me they're just dying to ditch me, lol

*gasps*

You don't mean...

-dun dun dunn-

Five days?!?

It is?! Even my "romances" have lasted longer than that, lol

30 + 30 + 30 + 30 + 30 + 30 + 30 = 30 * 7 = 210

To be fair, 4 days is quite an achievement!

Let's use order of operations (PEMDAS)...

2^3 - 8 / 4 x 2 + 7

First, solve the exponent (E in PEMDAS as there are no parenthases).

2^3 = 2 * 2 * 2 = 8

Now we have 8 - 8 /4 x 2 + 7.

Next, multiply/divide (whichever comes first left to right).

8/4 = 2

8 - 2 x 2 + 7...

2 x 2 = 4

8 - 4 + 7

Now, add/subtract (again, left to right).

8 - 4 = 4

4 + 7

I applaud you guest! That was hilarious!

18 / 1 1/2

First, change 18 into a fraction.

18 = 18/1

So...

18/1 / 1 1/2

Next, make 1 1/2 an improper fraction.

1 1/2 = 3/2

Now we have...

18/1 / 3/2.

Next, use "keep, change, flip."

Keep 18/1...

Change 3/2 into its reciprocal...

18/1 / 2/3...

Flip the division sign into a multiplication one.

18/1 * 2/3

Now, multiply each numerator by the other and vice versa for the denominators to get your answer.

18 * 2 = 36

1 * 3 = 3

36/3

Simplify...

Srsly? Cool! Congrats, I guess!

Hi Baller_Status,

you should give the duration of your romance in microseconds.

That would sound a lot more impressive!

sin (150)  = 1/2             csc (150) = 2

cos (150) = -√3 /  2       sec (150)  =  - 2 / √3

tan (150)  =  1 / √3       cot (150)  = √3
