Answer:

Step-by-step explanation:
we have that
The formula for the surface area of the enclosed space is

Solve for P
That means ------> isolate the variable P
Subtract lw both sides


Multiply by 2 both sides


Divide by h both sides


Rewrite

A) -8.93 > -8.4 is false. There is no solution.
B) -0.7 > -6.12 is true. There are infinite solutions.
C) 7.1 > 7.24 is false. There is no solution.
D) -3.2 > -3.6 is true. There are infinite solutions.
The first step to find how many 1/4 inch segments are in 1 and 1/2 inches is to convert 1 and 1/2 into an improper fraction.
To do this, convert 1 into a fraction with the same denominator as 1/2, which is 2.
1 = 1/1
1/1 = 2/2
Now add 2/2, which is the same as 1, to 1/2.
2/2 + 1/2 = 3/2
So 1 and 1/2 = 3/2
Now multiply both the numerator and denominator by 2 so you can see how many times 1/4 goes into the fraction equivalent to 1 and 1/2.
3/2 = 6/4
1/4 goes into 6/4 6 times, since the numerator of 1 goes into the numerator of 6 6 times.
So the answer is that 6 1/4 inch segments are in 1 and 1/2 inches.
