what is 8.94 rounded to the nearest tenth?

Look at the "hundreths" digit. If it's 5 or greater, we "round up.' If it's less than 5, we "round down."

In general, we use this rule for rounding to the nearest value specified. Look at the next digit - If it's 5 or greater, we "round up.' If it's less than 5, we "round down."

 Now, see if you can figure this one out........

On a map, the distance between two cities is 5.25 inches. The map scale is 1 in =25 mi. To the nearest mile, what is the actual distance between the two cities?

Well...1 inch would be 25 miles. ( 1 x 25)

2 inches would be 50 miles.  (2 x 25)

So, to find the number of miles, we have....... (inches) x (25 miles per inch)

See if you take it from here.......

You and 9 friends are waiting inline at a movie theater. You want to determine how many different orders you and your friends can stand in line. How many different arrangements are possible?

Well....notice that there qre 10 ways to choose the first person to stand in line, there are 9 ways to chooose the second person to stand in line, 8 eight ways to choose the third person, etc.

So we have

10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 ways = 10 !    where the little " ! " is known as "factorial"

And 10 ! = 3,628,800 arrangements  (Quite a lot !!!) 

The cow of a would be 9/15 

12.5 or just 12 if you want wholes

Suicide is the only option imo.

Assuming the sum of kinetic and potential energy is conserved, that is (1/2)mv₁² + mgh₁ = (1/2)mv₂² + mgh₂ then (1/2)v₂² = (1/2)v₁² +g*(h₁-h₂)  or v₂ = sqrt(v₁²+2*g*(h₁-h₂))

$${\sqrt{{{\mathtt{18.4}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{9.81}}{\mathtt{\,\times\,}}\left({\mathtt{35.1}}{\mathtt{\,-\,}}{\mathtt{22.5}}\right)}} = {\mathtt{24.202\: \!727\: \!119\: \!066\: \!561\: \!9}}$$

or approximately 24.2 m/s

In the USA where they put the month before the day, March 14th is known as pi-day.

Here in the UK, sadly, we don't celebrate pi-day. 

1.224 = e^k*20 Take logs of both sides: ln(1.224) = k*20;  rearrange: k = ln(1.224)/20

$${\mathtt{k}} = {\frac{{ln}{\left({\mathtt{1.224}}\right)}}{{\mathtt{20}}}} = {\mathtt{k}} = {\mathtt{0.010\: \!106\: \!209\: \!204\: \!506\: \!7}}$$

 so k is approximately equal to 0.01 per second. 

3.7*10⁵*9.5*10⁴ = 3.515810¹*10⁵*10⁴ = 3.515*10¹⁺⁵⁺⁴ = 3.515*10¹⁰

inverse of ln(x) is just e^x

inverse of log₁₀(x) is just 10^x

 inverse of log_b(x) is just b^x

It's on the bottom right of the calculator

Actually CPhill,

pi goes on forever and there is some crazy recoed of some person reciting over a billion numbers of pi from memory

And they have a supercomputer running 24/7 calculating pi as well

So this is what we got

-(2/3a)^4

So imagine the 2/3 and a have an imaginary ^1 so it is really

-( 2/3^1 a^1 )^4

so you take the exponet 4 and times it by the other exponets on 2/3 and a

Your final anwser is 

-16/81a^4 i believe

someone please correct me if im wrong

So you can figure out an equation that may be very similar but not = infinity or zero but instead a very lond decimal

I believe the anwser is 2..

Not sure though

Do good in school and get a goos job when you graduate college

It is 3+3 i believe..

If you can work a computer but not do addition...

You may need help

You should graph it but i do slopes so much in school that i can figure it out in my head.

so a line goes through (-4,2) and (2,5)

They way i do it is i use rise over run.

So it rises -3 and runs 6.

so -3/6

Then simplify

-1/2

You put the division sign in and then the denominator

Thank you

What do you mean by "unit number"?

0.40 aka 40%

None......I ate all 6 while she wasn't looking.....
