249.6/320=78%

It equals 2.506e + 18

What does the dash represent?

i mean 13 from 67

how do you divide 13 from 80?

nCr   = combinations  key

nPr   =  permutations  key

If the bill was $67 and they left an additional $13 tip....the whole thing must have come to $80

So   ...as a percentage of the bill (before the tip)  we have   13/67 x 100% = 19.4%

As a percetage of the total (with the tip), we have  13/80 X 100%  =  16.25%

The equation is given by :

y = -4.9t^2  + 20t       and using -b/2a  ....we have the time when it reaches its max height = -20/(2* -4.9)  = about 2.04 s

And the height at that time will be   -4.9(2.04)^2 + 20(2.04)  = about 20.4082 ft

thank you

They left a 20% tip.

$13 tip / $67 total without tip * 100 (to get the percentage) = 20.

I can SAY ALL  OF THEM.....I just can't REMEMBER ALL OF THEM   >>>>(psyche  !!!!)

[5(68) + x ] / 6 = 70       Multiply both sides by 6

5(68) + x  =  420  

340 + x  =  420     subtract 340 from each side

x = 80  inches tall

Thats why Chris i gave them the formula of finding the circumference

so they could simply use the calc next time ;)

Wait what?

Do not tell me we have a witch in the forums!

Dawn is the most terrifying and most evil witch of them all. No one has escaped from her style of torturey, and that's why about 3 years ago, Royality recruited her

Then write them down, Chris!

AND ALL OF THEM MUST BE IN ROMAN NUMERALS!

6 is a arabian number

Well.....if you sold it for less than you bought it....I'd say "0"

⁵ √[-32 / 343 ]  =

⁵ √[ (-2)⁵ / 3⁵ ] =  

-2 / 3

All of them.....!!!!

I think they wanted this, Dbg....

16^2  +  34^2  =

256 +  1156  = 1412

0  = -16t^2 + 100    subtract 100 from each side

-100  = -16t^2     divide both sides by -16

100/16   = t^2       take the positive root of both sides

10/4  = t   =  2.5 seconds

1/72 x= 1/9   multiply both sides by 72

x = 72 /  9   =  8

So   ....  96 / x =   96 / 8   = 12

If the dimensions are cut in half, the volume will be (1 /8)th of the original....

To see this .....note.... (1/2)W  x (1/2)L x (1/2)H  =  (1/8)V   where L, W and H are the original dimensions

So (1/8) 512 =  64 cu ft

Calm down, Titanium.....no use to "beat on" the questioners......your answer was good.....no need for your last statement.......this person probably knows how to use the calculator.....he/she just didn't know how to find the circumference.....
