Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandw
pav-90 [236]
If we are to consider the number of slices of bread first,

      number of sandwiches = (28 slices of bread)(1 sandwich/ 2 slices of bread)
      number of sandwiches = 14 sandwiches

If we are to consider the number of slices of cheese
 
      number of sandwiches = (45 slices of cheese)(1 sandwich / 3 slices of cheese)
     number of sandwiches = 15 sandwiches

Since, 14 is smaller than 15 then, 14 is the answer.

<em>Answer: 14 sandwiches</em>

Write the standard equation for a circle with center (−6, −8), that passes through (0, 0)
chubhunter [2.5K]
Standard equation:  (x-h)^2 + (y-k)^2 = r^2

Here,                        (0-[-6])^2 + (0-[-8])^2 = r^2
Find r:                           36        +   64         = 100, so r = 10

Then the desired equation is (x+6)^2 + (y+8)^2 = 10^2
