tan 36 = opp /adj        opp is the height   and    adj is  14 ft

Height of bird nest  

tan 36 = height / 14

14 tan 36 = height       but this is height above Juans eyes....so we must add 5 ft to get to the true height above the ground

14 tan 36     +5     = height  

.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  

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....

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

3/13    *   260 = #  small uniforms

Mason     11 questions    each worth  approx  9 points    9 point x 9 correct =~81%

Luke         18 questions   each worth approx  5 1/2         5 1/2  x 15 =~ 82 %

Sofie         20  q      each 5 points                                     5 x 17 = 85%

Jordyn       15  q      each approx 6 2/3                             6 2/3 x 12 = 80%

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....

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

or 

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