3.
Zielflug [23.3K]

Step-by-step explanation:

I just answered that. so, here again :

all we need to do is find the surface area, deduct windows and door areas.

that gives us the m² to be covered, which we have to multiply by $12.50 to get the total price.

the house surface area is like for a box, but we don't care about the top and the bottom. only about the walls.

the "box" is 18 m × 14 m × 4 m.

so, the front and the back walls are each

18m × 4 m = 72 m²

both front and back : 2×72 = 144 m²

each side wall is

14m × 4m = 56 m²

both sides : 2×56 = 112 m²

now for the deductions.

each window is

1.5 × 2 = 3 m²

both windows : 2×3 = 6 m²

the door is

1 × 2.5 = 2.5 m²

so, the total area to "side" is

144 + 112 - 6 - 2.5 = 247.5 m²

to side 247.5 m² it costs

247.5 × 12.5 = $3,093.75

One of the tables shows a proportional relationship. Graph the line representing the proportional relationship from this table i
Mkey [24]

Answer:

Table C

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Find the value of the constant of proportionality in each table

Table A

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-3 ------>k=-3/-1=3  

This table has different values of k

therefore

the table A does not represent a proportional relationship

Table B

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=3 ------>k=3/1=3  

This table has different values of k

therefore

the table B does not represent a proportional relationship

Table C

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=2 ------>k=2/1=2  

For x=2, y=4 ------>k=4/2=2  

This table has the same value of k

therefore

the table C  represent a proportional relationship

Table D

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=2 ------>k=2/1=2  

For x=2, y=6 ------>k=6/2=3  

This table has different values of k

therefore

the table D does not represent a proportional relationship
