Answer:
The maximum value of C is 68
Step-by-step explanation:
we have the following constraints
----> constraint A
----> constraint B
----> constraint C
----> constraint D
Find out the area of the feasible region, using a graphing tool
The vertices of the feasible region are
(0,0),(5,19),(5,0)
see the attached figure
To find out the maximum value of the objective function C, substitute the value of x and the value of y of each vertex in the objective function and then compare the results

For (0,0) -----> 
For (5,19) -----> 
For (5,0) -----> 
therefore
The maximum value of C is 68
Answer:
1233.02 to 2 D.P.
Step-by-step explanation:
4 % = 0.04
So to obtain the amount after increase by 4% we multiply by 1.04:
1235 * 1.04 = 1284.4
Decreasing by 4%: we mutriply by 1 - 0.04 = 0.96:
1284.4 * 0.96
= 1233.024.
Answer:
A= 6, B= -15
Step-by-step explanation:
Answer:
36, 180
Step-by-step explanation:
x = y/5, so y = 5x
y - x = 144
5x - x = 144
4x = 144
x = 144/4 = 36
y = 5x = 5*36 = 180
The two numbers are 36 and 180
Answer:
you need to substitute values on the next form of resolving this problem as follows...
A hose fills up a hot tub at a rate of 3.2 gallons per minute. How many hours will it take to fill a 300 gallon hot tub?
please explain the method of unit conversions as thoroughly as possible.
Solution:
The rate of fill up is, Rate = 3.2 Gallons / minute = 3.2 g/min
The hut tub volume is 300 Gallons
You can set up this problem as follows:
Every 3.2 gallons require 1 minute, How many minutes 300 gallons require?
3.2 g 1min
300 g ? min = (300 gallons x 1min/ 3.2 gallons)=(300/32)min
= 93.75 min
or simply the number minutes is the time required (T) the rate is (R) and the volume is (V)
such that T=V/R= (300g/3.2 g/min)= 93.75 min
