1. food a delicatessen has 12 pounds of plain sausage and 10 pounds of spicy sausage. a pound of bratwurst a
contains pound of plain sausage and pound of spicy sausage. a pound of bratwurst b contains pound of each
sausage. find the maximum number of pounds of bratwurst that can made.

Total Pounds of Bratwurst = 9

Step-by-step explanation:

Pounds of Plain Sausage = 12

Pounds of Spicy Sausage = 10

Bratwurst A =  1 pound of Plain Sausage and 1 pound of Spicy Sausage

Bratwurst B =  1 pound of Plain Sausage and 1 pound of Spicy Sausage

Total Pounds of Bratwurst = Bratwurst A + Bratwurst B

Total Pounds of Bratwurst = 9

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
