Susan is installing junction boxes in a living room wall which is 12 feet long. She has to install two boxes evenly spaced on th

e wall with the center point of the wall centered between the boxes (as if all arrows are equal in the picture below). The junction boxes are 4 11/16 inches wide. How much wall space will be between the two boxes? (Answer should be a mixed number, not a decimal.)

Answer:

Wall space between two junction boxes is 44\displaystyle\frac{7}{8}\text{ inches}  

Step-by-step explanation:

We are given the following information:

Length of wall = 12 foot = 144 inches

Length of Junction box = 4\displaystyle\frac{11}{16}\text{ inches}

There are two junction boxes to be arranged.

Total length of junction boxes = 8\displaystyle\frac{11}{16}\text{ inches}

Space left:

\text{Length of wall} - \text{Length of junction boxes}\\= 144 -8\displaystyle\frac{11}{16}\\= \displaystyle\frac{2154}{16}

Now, this left space have to be distributed in three equal part so that the arrangement could be of the form: space, junction box, space, junction box, space.

Space = \displaystyle\frac{2154}{16} \div 3=\displaystyle\frac{2154}{48} = 44\displaystyle\frac{7}{8}

Hence, wall space between two junction boxes is 44\displaystyle\frac{7}{8}\text{ inches}

Willy Wonka has 2 candies, Wonka bars and Everlasting Gobstoppers. Both have both natural sugar and sucrose in them. Each Wonka
love history [14]

Answer:

Wonka bars=3 and  Everlasting Gobstoppers=24

Step-by-step explanation:

let the wonka bars be X

and everlasting gobstoppers be Y

the objective is to

maximize 1.3x+3.2y=P

subject to constraints

natural sugar

4x+2y=60------1

sucrose

x+3y=75---------2

x>0, y>0

solving 1 and 2 simultaneously we have

4x+2y=60----1

x+3y=75------2

multiply equation 2 by 4 and equation 1 by 1 to eliminate x we have

 4x+2y=60

 4x+12y=300

-0-10y=-240

10y=240

y=240/10

y=24

put y=24 in equation 2 we have'

x+3y=75

x+3(24)=75

x+72=75

x=75-72

x=3

put x=3 and y=24 in the objective function we have

maximize 1.3x+3.2y=P

1.3(3)+3.2(24)=P

3.9+76.8=P

80.7=P

P=$80.9
