In chemistry, it is each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

 if a dune buggy is 61.7 kg, it is 61.7kg on theearth

I would start by factoring such that...

$${\mathtt{A}} = {\frac{{\mathtt{1}}}{{\mathtt{2}}}}{\mathtt{\,\times\,}}{\mathtt{h}}{\mathtt{\,\times\,}}\left({\mathtt{a}}{\mathtt{\,-\,}}{\mathtt{b}}\right)$$

From there you can rearrange to find that....

$${\frac{{\mathtt{2}}{A}}{\left({\mathtt{a}}{\mathtt{\,-\,}}{\mathtt{b}}\right)}} = {\mathtt{h}}$$

There are two equations that relate in this case, those of the surface area and the volume of a cylinder.

$${\mathtt{V}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{h}}$$

$${\mathtt{A}} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{r}}{\mathtt{\,\times\,}}{\mathtt{h}}$$

You did not give a set of variables but you can find the height using one or both of these equations.

You need to write the 2 as the exponent instead of the coefficient. e^ln3^2

This is so you can cancel out the e and ln. This will leave you wtih 3^2

Your answer should be 9

I got that x=-x  

So I think that's considered no solution.

0.0000006 is your answer

The area of the base  = (length of one side of the base)² = 2² = 4 square units

Also, there are 4 triangles, each with a base = 2 and a height = slant height =7

So each has an area = (1/2)(b)(h) = (1/2)(2)(7) = 7

And 4 tmes this = (4)(1/2)(2)(7) = (2)(2)(7)  = 28 sq units

So the "formula" for the surface area = b² + 2(b)(h), where b is one side of the base and h is the slant height of the pyramid

And the surface area of this particular pyramid = (28 + 4) sq units = 32 sq units.

The answer is 120,000

You should've subtracted 7 from the guy who put down all those sevens.

easy, 9 woods.

I can't actually show the graph but I can tell you how. This function represents a line. Your Y-intercept should be placed at (1,0). -5/1 is your slope. Go down five and right one. You need to points to make a line, so connect those points and put arrows at the ends. Since this is an inequality that has y as less than, shade below the line.

This is your Fast Answer

What is the surface area of a square pyramid

for a base length of 2 and a slant length of 7?

lateral surface area = 28 m²
base surface area = 4 m²
total surface area = 32 m²

3x+21-20=5x+7                   Distribute the three to the contents of the parenthesis

3x+1=5x+7                          Go ahead and combine the 21 and -20

1=2x+7                                Subtract 3x from 5x

-6=2x                                  Subtract 7

-3=x                                     Divide by 2

Calling Bertie, CPhill and Rom (Troll alert! General quarters!)

Along with Melody and Alan, we need input from Bertie, CPhill, and Rom, too.

With the top brains represented here that Troll might comeback and bite one or more.

I know he’ll bite FoxTears for saying, “Mine was assuming the numbers can be reused” (your formula (40C5) contradicts this).

The Troll will follow-up, by asking what is the probability of (something) of (five, six or seven) mathematicians getting a probability question correct.

Then he’ll say about the same as walking, blindfolded, through a large buffalo heard and stepping in four piles with both feet.

What’s annoying: he’s usually right.

CPhill might not be able to make it. He might be trying to get the “Roman Zero” from inside Sisyphus’s boulder.

Maybe he could take a break and visit. He’s not been around for a day or two. I hope he wasn’t squashed by the boulder.

No matter: cartoon physics seem to apply in that realm. If he does visit, maybe one of those angels will help him get the “Roman Zero.”

Here we have net force = mass*acceleration.

net force = force of gravity - frictional force (assuming any other forces are negligible).

Assuming the frictional force is constant throughout his slide, we have:

101*9.81 - fricforce = 101*3.2    (where gravitational acceleration = 9.81m/s²)

rearrange to get fricforce:

fricforce = 101*9.81 - 101*3.2 = 101*6.61 N

$${\mathtt{fricforce}} = {\mathtt{101}}{\mathtt{\,\times\,}}{\mathtt{6.61}} \Rightarrow {\mathtt{fricforce}} = {\mathtt{667.61}}$$ Newtons

No. In general, unless a prime number in a fraction divides the other number in a fraction, it can't be reduced. Thus, 11 is prime and doesn't divide 100, so that's all we can do.

mass (kg) = force (N) divided by acceleration (m/s²)

I'll let you plug in the numbers here.
