Rules of similar triangles....
2 is to 3 as bd is to bc
2/3 = bd/bc
2/3 bc = bd
2/3 4 = bd
Then you can use the same rules (or pythagorean theorem) to find BE
Stereotypical for Asian parents to do what? Whip some asss?
cos theta can be 1/2 and 1.
It just sterotypical for asian parents to do that
Oh? Is an asss whipping more likely or less likely from Asian parents?
depends if parents are asian
An asss whipping?
15 - 4 = 11
11/15 = 0.73333333333
So you got a 73%
The answer is 18.
I understand how the side BC is 4 but how did you get BD or BE? What work did you do, a proportion?
Isn't it an arithmetic series with terms =1, 2, 3, 4...........100 repunits.
The sum(S) = [100 x 101] / 2 =5050
Sum of digits of S =5 + 0 + 5 + 0 =10
I will guess 15
The answer is 35.
a1 = 3 d = 5
xn = a1 + d(n-1)
253= 3 + 5(n-1)
50 = n-1
n= 51
Sum = S = (n/2) × (2a + (n−1)d) = 6528
There are 5 cats for every (5+3) animals so 5/8 are cats 5/8 x 104 = 65 cats
thanks
BC = 4 (pythagorean theorem)
BD = 2/3 (4) Similar triangles
BE = 2/3 (5) Similar triangles
I was careless. I will attempt that again.
I suppose that it depends on your understanding of the word distinct.
In the context of this question, I would take it to mean different.
Let 'x' be her income
tax will be p ( 28000) + (p+2)(x-28000) = (p+.25) x
28000p + px-28000p +2x -56000 = px + .25x
2x-56000 = .25x
-56000 = -1.75x x =$ 32000
PLZ HELP!!!!!!!! QUICK!!!!!!!

Denote \(r_n\) the nth repunit.
\(\begin{array}{rcl} S &=& \displaystyle \sum^{100}_{n = 1} r_n\\ &=& \displaystyle \sum^{100}_{n = 1} \sum^{n-1}_{k = 0} 10^{k}\\ &=& \displaystyle \frac{1}{10}\sum_{n = 1}^{100} \sum_{k = 1}^{n} 10^{k}\\ &=& \displaystyle \dfrac{1}{10} \sum_{1 \leq k \leq n \leq 100} 10^{k}\\ &=& \displaystyle \dfrac{1}{10}\sum_{k = 1}^{100} \sum_{n=k}^{100} 10^{k}\\ &=& \displaystyle \dfrac{1}{10}\sum_{k = 1}^{100} \left(10^{k} (101 - k)\right)\\ &=& \displaystyle \dfrac{1}{10}\left(101\left(\dfrac{10\left(10^{100} - 1\right)}{10 - 1}\right)-\sum_{k= 1}^{100}k\cdot 10^{k}\right) \end{array}\\ \text{Let }S_{AG} = \displaystyle \sum_{k = 1}^{100} k\cdot 10^{k}\\ \begin{array}{rcl} S &=& \dfrac{101}{9}\left(10^{100} - 1\right) - \dfrac{1}{10}S_{AG}\\ S_{AG} &=& 1\cdot 10^1 + 2\cdot 10^2 + \cdots + 100\cdot 10^{100}---(1)\\ \dfrac{1}{10}S_{AG} &=& 1 + 2\cdot 10^1+\cdots +100\cdot 10^{99}---(2)\\ (1)-(2):\dfrac{9}{10}S_{AG} &=& 100\cdot 10^{100} - (1 + 10^1 + 10^2 +\cdots + 10^{99})\\ &=&10^{102} - \dfrac{10^{100} - 1}{9}\\ S_{AG} &=& \dfrac{10^{103}}{9} - \dfrac{10^{101} - 10}{81}\\ S &=& \dfrac{101}{9} (10^{100} - 1) - \left(\dfrac{10^{102}}{9}-\dfrac{10^{100} - 1}{81}\right)\\ &=& \dfrac{10^{100}}{9} - \dfrac{101}{9}+\dfrac{10^{100} - 1}{81}\\ &=& \dfrac{10^{100} - 1}{9}+\dfrac{10^{100} - 901}{81} \end{array}\\\)
How may laps does Odell run? 250m/min * 30 min / (pi *d) = 250*30 / (pi *100) = 23.87 laps
Kershaw runs 300m/min *30 min /(pi *d) = 300*30/(pi*120) = 23.87 laps in the same time
The pass each other TWICE each lap and only ONCE for the .87 lap = 47 times (?) Not positive....
