You are opening a restaurant. in the figure, the dining area of the restaurant is rectangle jklm. each unit in the coordinate plane represents 1 foot.

the points are j(3,30) k(33,30) l(33,0) m(3,0)

part a. find the area a of the dining area.

a= ft2

part b. a local fire safety code recommends seating no more than one person per 15 square feet. find the maximum number of people the restaurant should seat in the dining area.

maximum number of people:

a.

b.

Step-by-step explanation:

The rectangle JKLM is attached, where each unit in the coordinate plane represents 1 foot.

a. You cab ibserve in the figure that the dimensions of the rectangle are:

by

Threfore, in order to calculate the area of the dining room, you can multiply these dimensions.

Then, this is:

b. Then, in order to find the maximum number of people the restaurant should seat in the dining area (according to the recommendation from the Local Fire Safety) you need to divide the area of the dining room by 15 square feet.

Therefore:

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
