One bunch of cookies requires two eggs in 2 1/2 cups of flour how many cups of flour you need to make 3 1/2 batches of cookies

8 3/4 cups

Step-by-step explanation:

1 batch of cookies            3 1/2 batches

  =    

2 1/2 cups flour                   x cups of flour

using cross products

1 * x = 2 1/2 * 3 1/2

changing 3 1/2 to an improper fraction ( 2*3+1) /2  = 7/2

changing 2 1/2 to an improper fraction  (2*2+1)/2 = 5/2

x = 5/2* 7/2 = 35/4

changing back to a mixed number

4 goes into 35 8 times (4*8 = 32)  with 3 left over

8 3/4 cups

- 1.613 = -1.6 or -1.61

-1.522 = -1.5 or -1.52

0.587 = 0.6 or 0.59

3.079 = 3.1 or 3.08

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
