You calling me a rat?!?!?! How rude!!!!!!

I went back and "upped" all the points that I could, DS.....apparently........more than one person must have "thumbs downed"  these posts....some are still showing minus values....

I did all I could for you "rats"....!!!

OR---

You can use your computer.

Hold ⇑SHIFT and then press 5.

Then, the % sign will appear.

Hope it helps!

Good thinking, CPhill. 

I like that question.

Did you give me negative points, CPhill???????

Hit the "2nd" key......it's the 4th button over.....

Thanks, rosala

rosala, I didn't give you too many negative points. It was someone else, not me.

Thanks, Melody!

$${\mathtt{0.2}}{\mathtt{\,\times\,}}{\mathtt{4}}\% = {\mathtt{0.008}}$$

$${\mathtt{0.008}}$$ is the answer.

40 mg x (1 g / 1000 mg) x (1 kg / 1000 g) = .00004 kg ....or..... 4 x 10^-5 kg in sientific notation

Yes. I am online.

Scroll down to the bottom of the page, and you will see who is online.

Hope it helps!

$${\mathtt{30}}{\mathtt{\,\times\,}}{\mathtt{1}} = {\mathtt{30}}$$

$${\mathtt{30}}$$ is the answer.

First comes the chicken.

Read the bible. That can help you too.

Yes. Really updated. It is one of the best. It gives hundreds of numbers, unlike other calculators. (As far as I know)

What does Σ mean?

Can you please explain it to me please?

$${\mathtt{x}} = {\mathtt{5}}$$

You can find the answer by substituting x many times. To the fifth time, the answer will equal 52 and 52. I will show you.

$$10x+2=12+8x=10*5+2=12+8*5$$

Now, multiply.

$${\mathtt{10}}{\mathtt{\,\times\,}}{\mathtt{5}} = {\mathtt{50}}$$

$${\mathtt{8}}{\mathtt{\,\times\,}}{\mathtt{5}} = {\mathtt{40}}$$

Now, you add.

$${\mathtt{50}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}} = {\mathtt{52}}$$

$${\mathtt{40}}{\mathtt{\,\small\textbf+\,}}{\mathtt{12}} = {\mathtt{52}}$$

Now, let's compare them.

$${\mathtt{52}} = {\mathtt{52}}$$

So, the equation is true.

Hope it helps!

$$20-15=5$$

5 students survived.

Try your best to know math because in life, you have to count, add subtract, and do many other things because without math, we can't survive.

Our houses are not going to be built correctly, they are going to get destroyed,...

You should evacuate the area as quick as possible. It is very important so you can survive.

And Melody, there are tornado's in the U.S.

$${\frac{{\mathtt{164}}}{{\mathtt{16}}}} = {\mathtt{10.25}}$$

So, $${\mathtt{y}} = {\mathtt{10.25}}$$.

Melody, the first one is REALLY EASY.

$${\frac{{\mathtt{3}}}{{\mathtt{5}}}}$$

Melody, can I do another one please?

I solved the one you told me to do.

Nice triangle Melody! I like your answer.

Can somebody explain me this problem?

Now, I will do this one.

#57 (3x 2/3)^7-6

Substitute x.

$${\mathtt{x}} = {\mathtt{1}}$$

Now, multiply.

$${\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{1}} = {\mathtt{3}}$$

Now, subtract.

$${\mathtt{7}}{\mathtt{\,-\,}}{\mathtt{6}} = {\mathtt{1}}$$

Now, the whole question together.

$$(3\frac{2}{3})^1$$

Now, finish the expression.

$$(3\frac{2}{3})^1=3\frac{2}{3}$$

So, $$3\frac{2}{3}$$ is the answer.

There are many solutions, Nataszaa.

#56 (x-4/7)^7

I will solve this one, okay?

Substitute x.

$${\mathtt{x}} = {\mathtt{2}}$$

In this case, $${\mathtt{x}} = {\mathtt{2}}$$.

Now, turn 2 into a fraction.

$${\mathtt{2}} = {\frac{{\mathtt{2}}}{{\mathtt{1}}}}$$

Now, subtract.

$${\frac{{\mathtt{2}}}{{\mathtt{1}}}}{\mathtt{\,-\,}}{\frac{{\mathtt{4}}}{{\mathtt{7}}}} = {\frac{{\mathtt{10}}}{{\mathtt{7}}}}$$

But now, turn $${\frac{{\mathtt{10}}}{{\mathtt{7}}}}$$ into a whole number.

$${\frac{{\mathtt{10}}}{{\mathtt{7}}}} = {\mathtt{1.428\: \!571\: \!428\: \!571\: \!428\: \!6}}$$

Now, that you have the whole number, round it to the nearest tenths.

$${\mathtt{1.428\: \!571\: \!428\: \!571\: \!428\: \!6}} = {\mathtt{1.4}}$$

Now, do the exponent $${{\mathtt{1.4}}}^{{\mathtt{7}}}$$.

$${{\mathtt{1.4}}}^{{\mathtt{7}}} = {\mathtt{10.541\: \!350\: \!4}}$$.

That's your answer.
