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.....

(4x2) + (6/3) – 5 =
(8) + 2 - 5 =
10 - 5 =
5
√(25c³) =
√25 * √c^3
√5^2 * √c^3 =
5 * √c^2 * √c =
5c √c
Here's a good website that explains this.........http://www.purplemath.com/modules/radicals.htm
Yep...but maybe you will just be...... Dbg 1.0 ......!!!!
Well....after my eyesight recovers from reading this question, we have...
2727miles / 27mpg x $4.04 = $408.04
Dbg = DJ !!!!
The side length will be given by :
s = √[ 2*21^2 - 2(21)(21)cos(120) ] =
√[2*21^2 - 2(21)(21)(-1/2)] =
√[2*21^2 + (21)(21)] =
√[3*21^2] =
21 √ 3 = about 36.37 units
