Achicken farm orders bags of feed from two farmers. store x charges $20 per bag, and store y charges $15 per bag. the farm must obtain at least 60 bags per week to care for the chickens properly. store y can provide a maximum of 40 bags per week, and the farm has committed to buy at least as many bags from store x as from store y. the chicken farm wants to minimize the cost of ordering feed. let x represent the number of bags of feed from store x and y represent the number of bags of feed from store y.

x + y ≥ 60; y ≤ 40

Step-by-step explanation:

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
