sqrt (65^2 - 16^2) = 63 cm = the base length
Here's something else that might help : http://www.purplemath.com/modules/exponent3.htm
(4.6 / 9.8) * 10^3 =
0.4693877551020408 * 10^3 =
4.693877551020408 * 10^2 [approx. ]
sin60°cos30°-sin30°cos60°=sin30°
(sqrt(3)/2)(sqrt(3)/2) - (1/2)(1/2) = (1/2)
(3/4) - (1/4) = (1/2)
Which is true.....
Sorry....the way you have written the question, it makes no sense to me.
3y+8-7y-1= combining like terms we have
-4y + 7
2x-5y=-3 add 5y, 3 to both sides and rewrite this as
5y = 2x + 3 divide both sides by 5
y = (2/5)x + (3/5) and the slope is the thing in front of "x".....in this case, (2/5)
(3.2*10^4) / (6.8*10^3) we have
(3.2 / 6.8) * (10^4 / 10^3) =
0.4705882352941176 * 101 =
4.705882352941176 * 100 [approx. ]
Go ahead and post a specific problem......
Hey, Dragonlance....good research on F 451 ....!!!
It's a good book......kind of like "1984" by George Orwell.......
[I'm a big fan of Sherlock Holmes, too....!!!]
