From A to G is 180   then add  44   and 53    = ........

4 rectangles    4x4    6x4  4x4   2x4

Two trapeoids     2 *  1/2 ( 6+2) x 3.5     add 'em all together

\( $0.\overline7$\)       =     7/9

2  =   (1 + .105)ⁿ     Solve for 'n'       2 represents doubling       .105 = interest rate

n = 6.94 years

Draw a venn diagram:

Well....you can't       if only 25 have a card.....how can 50 have a card and a bike?    

         Please proofread ....what should '25 had a mastercard ' be?

a = adult                         revenue = 15a

s=student = 300-a          revenue = 11(300-a)            added = 3630

15a + 11(300-a)   = 3630                      solve for 'a'               then s = 300-a

Find the side of the square...that is equal to AD

s^2 +s^2 = 26^2

s^2 = 26^2 / 2

s = ~18.4 cm = AD

Area of square   -  1/4 circle area (radius = 18.4)

18.4  * 18.4    - 1/4 pi (18.4)^2    = ..........    cm^2

Area of large triangle - area of smaller triangle

1/2  20 * 20      -   1/2  10 * 15   =    shaded area  

2⁵⁵ < 4³³ < 3⁴⁴

$25 (2/3) (4/7)  = 25 (8/21) = $ 9.52             $  200/21       $  9  11/21
