Where is this "tithe earth" whose density is \(5.5g / m^3\), what do you want to say?

Ten kids make ten valentine's each = 100

So we have Kent:Mike at 7:3. We also have Mike:Zam at 6:5. We can bring these into comparable ratios by doubling Kent:Mike, so we have
Kent:Mike:Zam at 14:6:5. This says that, for every set of (14+6+5) = 25 cards, Kent owns 14, Mike has 6, and Zam has 5.

Now, we have 575 total cards, which is (575 / 25) = 23 sets of 25 cards. Kent owns (23*14) = 322 of them, Mike owns (23*6) = 138, and Zam owns (23*5) = 115.

Finally, then, Kent owns 322 - 115 = 207 more cards than Mike does.

2y=8x-6

y = 4x -3        slope , m , = 4        perpindicular slope = - 1/m = -1/4

y = -1/4 x + b            sub in the given point

3 = -1/4 (-3) + b           to find b = 2 1/4

y = - 1/4 x + 2 1/4

x = original amount

   spending 1/5    leaves 4/5

(x-390) * 4/5  = 3/7 x       solve for 'x'

Multiply both fractions by 1000:

0.33 x 1000 ==330

0.334 x 1000 ==334

Now compare: which is bigger? 330 or 334

B==Blue, G==Green,  R==Red

G / B ==1.5 / 1, 

R / G==3 / 2,

[B + 10] ==3/8[G + B + R + 10], solve for B, G, R

B==8,  G==12,  R==18 - original number of marbles in the Jar.

The value of n is 40.

2+10+50+250+1250+ 6250+31250=.........

area = pi r^2

  100pi = pi r^2

r^2 = 100

r = 10

x = number of lights             s = small tree lights               L = large tree  = s+16

1/3 x  =  12 s    or s = 1/36 x        (now there are 2/3 x lights left)

       and 

(2/3x) 3/4 = 10 (s+16)         sub in the green equation for s

1/2 x = 10(1/36 x + 16)

x = 720 lights

The probability is $\boxed{\dfrac{\pi \sqrt{3}}{27}}$.

This is easy if you use parameteric forms.

The probability is 2/15.

Basketball = (300 / 4) - 25 = $ 50 

Thankyou

x = original count of marbles

   losing 2/7ths means he has 5/7 ths of original left

5/7 x - 48 = 1/3 x

x = 126

at the end he has 1/3 of the original amount = 42 marbles

   3   3    3    3   +   5   5   5   5  5  5    

b/g = 5/4

b = 5/4 g

   = 5/4(60) = 75 boys

Appears so...... !

100 c 3 = 100!/(97!3!) = 161 700 ways

b/j = 4/5      or     b = 4/5 j

(b-78)/j = 1/2

 b - 78 = 1/2 j

4/5 j - 78 = 1/2 j

3/10 j = 78

j = 260
