15 3/4   - 2 cups saved = 13 3/4 cups available for bread

13 3/4   /   5 1/2     =  55/4   /   11/2    =     55/4  * 2/11 = 110/44 = 110/44 = 2.5 breads

C would have modulus of sqrt 10     to correspond to answer found in part A of the Question

74 x  5%    =   74 x .05 = 3.70 dollars

I think it is an infinite geometric sequence with   a1 = 4/9   r = 1/9

sum = a1 / (1-r) = 4/8 = 1/2

Each row has the same number of coins in it as the row number

12th row has twelve coins   ....look at the patterns of the sides of the triangle

151     1 10 10

151 151 151 151     twelfth row starts with 1   has 12 coins   

                                                1 5 10    1 5 10    1 5 10    1 5 10       Add the red numbers for answer (16 * 4 = 64 cents)

You're welcome....I hope you understand the solution !  

Midpoint is the center   ( h, k )  =  (1,-2) 

   radius is 1/2 diameter      diameter is distance between two given points  = 14     radius = 7

Standard form of circle equation is

(x-1)^2 + (y+2)^2 = 7^2  

Calculate the entire area of the 60 degree arc then subtract the area of the equilateral triangle

pi r^2  *  60 / 360   = 6 pi

Area of eqil triangle    sqrt 3/ 4  * 6^2

      6 pi   -   sqrt 3  / 4   * 36 = 3.261 cm²

Vertical angles are equal soooo  

x+23 = 5x-9

x = 8                        then b =   5(8) - 9 = _________________

You will need a trig calculator for this

Right triangle    cosin 22 = adjacent side / hypotenuse

                          cos 22 = a / 30

                              a = 30 * cos 22^o                Make sure you use 22 degrees and NOT 22 RADIANS in your calc !
