.5%    means    .005  of  each  ml    is   the  GRAMS of  drug

.005 * x  gm / ml   = 10 mg

5 mg /ml *  x   = 10 mg

x = 2 ml  

Is it B ?

Factor out the 3          3 ( 1-2r)

gyroids represent   1 out of  1+3 = 4     or  1/4 of the total

345 - 252 = the increase             1/4 of this increase will be the gyroid increase....

1 - When Bryan initially picked one of the 10 boxes, his chances were: 1/10 and the chances of the other 9 boxes were: 1/10 for each box.

2 - When Carl opens 5 empty boxes, the chances of your box is still 1/10 but the chances of the remaining boxes suddenly jumped to 1/5 for each box including yours.

3 - So, if you keep your original box, your chances are still 1/10 because you picked it out of 10 boxes. But, Carl is giving you the chance to increase your chances from 1/10 or 10% to 1/5 or 20%. Therefore, you should switch your original box to one of remaining 4 boxes, therby doubling your chances of winning the gold coin, from 10% to 20%.  

Small uniforms represent  3   out of   3+4+6 = 13    or    3 out of 13 are small     3/13

3/13    *   260 = #  small uniforms

Yes, x = 21 , MS......then you use this value of x to compute the sides of the figure to calculate the perimeter of the triangle....

The ordered pair would be (55, 14)

1/6   +   1/4   =  1 / T     Solve for T   the time for two working together.

or 

(T₁  x   T₂₎   /   (T₁ + T₂)    = T_combined

The exterior angles sum to 360^o, so if the "unit" exterior angle is x then 2x + 3x + 4x = 360 or x = 40^o. The smallest exterior angle is 2x = 80^o. So the largest interior angle is 180^o - 80^o = 100^o.

THE ANSWER IS A

If we let 'x' equal the number of adult tickets then 8-x is the number of kid tickets.   Te revenue from adult tickets would be $8 times x and the revenue from kid tickets would be $3 times 8-x.   Summed together the revenues would equal $ 33.   Then you solve for 'x' the number of adult tickets and  8-x  the number of kid tickets.

o   would to often be confused with 0 (zero)   .... I imagine.  

Its just a subscript to denote a difference in terms.....   like   x₁   is different than the second x   or   x₂ ,   it doesn't imply any mathematical calculation like   x²   does   (x squared.....or   x * x )

"A peculiar die has the following properties: on any roll the probability of rolling either a 2, a 3, or a 5 is 1/2, just as it is with an ordinary die. Moreover, the probability of rolling either a 5, a 6, or a 4 is again 1/2. However, the probability of rolling a 5 is 3/16, not 1/6 as one would expect of an ordinary fair die.
From what you know about this peculiar die, compute
A) the probability of rolling either a 2, a 3, or a 1;
B) the probability of rolling anything but a 1."

Here is a formula for area of octagon when you only know one side length:

The area of an octagon = 2 x (1 + √2) x B²       Where B = 8 cm in this case....

"Determine the value of loga18 if loga2= 0.2789 and loga3= 0.4421"

18 = 2*3² so log_a18 = log_a(2*3²)

Using the properties of logarithms we have log_a(2*3²) = log_a2 + log_a3² = log_a2 + 2*log_a3
