Answer: 24 inches.
Step-by-step explanation:
If each section length is 4 inches, then that means that each person will need to eat a sandwich section that is at least 4 inches.
There are 6 people, which means that each person will eat 4 inches of a sandwich.
To calculate the length of the sandwich Riko should order, we should mutliply 6 by 4, because there are 6 people and each person will be eating 4 inches of a sandwich.
6 x 4 = 24.
In conclusion, the smallest sandwich Riko should order is a sandwich that is 24 inches long.
(Quick Note: This is also the smallest sandwich Riko could order, because the text states that each person eats at least 4 inches.)
Answer:
Plumber A
Step-by-step explanation:
Given the following :
Hours ___repair cost
________A ____B____C_____D
1 ______$35___55___50____50
2 _____ $65__ $75__ $75__ $60
3 _____ $95__ $95 _$100 ___$70
Charge plan:
Flat fee(x) + hourly rate(y)
For 1 hour:
Plumber A:
x + y = 35 ; x = 35 - y
x + 2y = 65 ;
35 - y + 2y = 65
y = 65 - 35 = $30 hourly
Plumber B:
x + y = 55 ; x = 55 - y
x + 2y = 75 ;
55 - y + 2y = 65
y = 65 - 55 = $10 hourly
Plumber C:
x + y = 50 ; x = 50 - y
x + 2y = 75 ;
50 - y + 2y = 65
y = 65 - 50 = $15 hourly
Plumber D:
x + y = 50 ; x = 50 - y
x + 2y = 60 ;
50 - y + 2y = 60
y = 65 - 50 = 10 hourly
Hence, Plumber A charges the highest hourly rate at $30 per hour
Answer:
58 at the point (9,8)
7 at the point (1, 1)
Step-by-step explanation:
The maximum points will be found in the vertices of the region.
Therefore the first step to solve the problem is to identify through the graph, the vertices of the figure.
The vertices found are:
(1, 10)
(1, 1)
(9, 5)
(9, 8)
We look for the values of x and y belonging to the region, which maximize the objective function . Therefore we look for the vertices with the values of x and y higher.
(1, 10), (9, 5), (9, 8)
Now we substitute these points in the objective function and select the one that produces the highest value for f (x, y)
The point that maximizes the function is:
with
Then the value that produces the minimum of f(x, y) is (1, 1)
