Given:
The inequalities are:
or 
To find:
The solution for the given inequalities and graph the solution.
Solution:
We have,
or
Solve the above inequalities separately.
Divide both sides by -5.
...(i)
And,
Divide both sides by 2.
...(ii)
From (i) and (ii). we get
or
The interval notation of the solution is 
.
The graph of the solution is shown below.
Ahh ok so split it up into two rectangles:
Rectangle one:
A=lw
A=4(12)
A=48
Rectangle two:
A=lw
A=10(2)
A=20
Add both areas up to get 68 ft squared!! :)
Answer:
less than, less than, greater than (from top to bottom)
Step-by-step explanation:
Answer:
10 minutes
Step-by-step explanation:
To solve this , we need to first calculate the volume of the rectangular prism. Let’s say this is V.
Mathematically, V = w h l where w, h and l are width , height and length respectively.
V = 20 * 18 * 10 = 3600 in^3
Now to get the number of minutes, we divide the volume by the draining rate.
That would be 3600/360 = 10 minutes
1/2(3g - 2) = g/2....multiply the entire equation by 2
3g - 2 = g
-2 = g - 3g
-2 = -2g
-2/-2 = g
1 = g
