2 d^2 = 162 divide both sides by 2
d^2 = 81 sqrt both sides
d=9 (or -9)
THAT is the equation of a line in the form y=mx +b (where b = 0) and the slope is -4/5
sin^2(theta)
Let the original price =x
0.15x = 120 divide both sides by 0.15
x =120 /0.15
x =$800 original price.
4 hours = 240 min ....so...
25 / 240 =
5 / 48
(12)(11!) = 12! That ia right!!. All they are asking is to multiply: 12 x11! =12 x [11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1] ALL the stuff in brackets is: 11!. And then just multiplied by one more number 12, which is the same as 12! =12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1.And that is it.
Math is here to progress the knowledge, technology and understanding of the universe of humanity... and also to cause stress to adolescents so that more money is spent on health care and other things that we are convinced we need because of the media so that the economy of the country and government grows.
(12)(11!) = 12!
Unless 12! is divided by 10!. You should submit your question as it is stated in your book or assignment, so that we know exactly what is being asked from the numbers provided.
Shouldn't it be 12! = (12)(11)(10)(9)(8) etc.? Yes. Continue all the way down to x 1.
^Yep he got it!
12x + 18
Take out the GCF = 6 and we have
6 ( 2x + 3 )
Thanks!
Good, Isabelle !!!
Very nice, Aleguan......!!!
Okay, so for example you said you have 6 numbers:
1,2,3,4,5,6 you would cross of1&6, 2&5, and would be left with 3 and 4. You don't cross those off instead you would add them together and divide them by 2 and get the median.
5x-6y=9. If we replace y with (-2/3), we get 5x-6(-2/3)=9. Now to solve for x, we have to get x alone on one side of the equals sign. So let's move everything on the left side except for the x (which includes the 5 that the x is being multiplied by). Doing this, we get 5x=6(-2/3)+9. We might as well multiply the 6 by the (-2/3) to get it out of the way now. 6 x -2/3 is -4, so we now have 5x=-4+9. Add the -4 and 9 to get 5. Now we have 5x=5! So all we have to do is divide 5x by 5 to get x alone without being multiplied by anything. But wait! If we divide one side of the equation by 5 we have to divide the other side as well, so 5x/5 is x and 5/5 is 1. Finally, we are left with x=1. And that is the x-value. 1.
Let the original radius = R and let the change in radius = r
Then.....
The new circumference = 2* pi * R + 48 inches = 2 * pi * (R + r) .....so....
2* pi * R + 48 inches = 2 * pi (R + r) divide each side by 2 pi
R + 24 / pi inches = R + r subtract R from both sides
24 / pi inches = r ≈ 7.64 inches
Consider the fraction \({1 \over \sqrt{8}}\)
Depending on the course you're taking you can leave the radical in the denominator, or you rationalize the fraction by multiplying the numerator and denominator by \(\sqrt{8}\)
to get \({1 \over \sqrt{8}}*{\sqrt{8} \over \sqrt{8}} = {\sqrt{8}\over 8}\)
that is an inapropriate response to this question
