all the lines meet up at the center, so there are 11 triangles, that have equal area. each triangle has an area of 15, so 11x15=$\boxed{165}$
9+10=21_9
You do Intro to algebra B. What's ur user?
lets say there are b boys. This means tehr are 3b/4 girls. b+3b/4=7b/4=63
solving for b, we have
b/4=9
b=36
3/4 x 36 = $\boxed{27}$
Lets call the point of dilation O.
XX'=4XO
YY'=4YO
XO=1/4 of XX'
YO=1/4 of YY'
X'Y'=4XY
XY=X'Y'/4
X'Y'=2
XY=$\boxed{\dfrac12}$
"In the history of the United States, carpetbagger was a derogatory term applied by Southerners to opportunistic Northerners who came to the Southern states after the American Civil War, who were perceived to be exploiting the local populace for their own financial, political, and/or social gain."
-Wikipedia
there are 4x3x2 ways to get one from each suit, which includes aces.
there are 4x4x4x4 ways in total, so (4x3x2)/(4x4x4x4)=$\boxed{\dfrac3{32}}$
1/3 of the spinner = 12 x 1/3 = 4
there are 4 indigo blue, so the answer is $\boxed{Indigo \ Blue}$
probability you choose an ace:4/52=1/13
probability to choose an ace 4 times: (1/13)^4 = $\boxed{\dfrac1{28561}}$
first find out how many there are:
1/2 x 32 + 5 = 16 + 5 = 21
21 = how many are not plain
32-21=11.
There are 11 plain popcorn balls. this means that the chance of choosing a plain is $\boxed{\dfrac{11}{32}}$
