B :) it’s 1134 you’re welcomeeeeeeww
You find the time and how fast it is going then you divide the distance by the time to find the unit rate. Hope it helped. :)
The formula for the circumference of a circle:
pi×diameter
so the ratio is this:
circumference/diameter=pi
Answer:
$56,000
Step-by-step explanation:
If x is the number of days that Refinery A is in operation, and y is the number of days that Refinery B is in operation, then:
200x + 100y ≥ 800
300x + 100y ≥ 900
200x + 200y ≥ 1000
The total cost is:
C = 12,000x + 10,000y
x and y must be integers. Possible combinations are:
x = 0, y = 9
x = 1, y = 6
x = 2, y = 4
x = 3, y = 2
x = 4, y = 1
x = 5, y = 0
The costs of these combinations are:
The minimum cost is $56,000.
