1/2 = 0.5

12 & 1/2 = 12 + 1/2 = 12 + 0.5 = 12.5

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

Refer to the diagram below. Note how I divided the figure into two rectangles.

The larger red rectangle is 12.5 feet by 10 feet. It has area 12.5*10 = 125 square feet.

The smaller blue rectangle has dimensions 4.5 feet by 5 feet (the 5 is from 15-10 = 5), so it has area 4.5*5 = 22.5 square feet

Now add up those individual areas to get the total area

125+22.5 = 147.5

Then convert that to a mixed number

147.5 = 147 + 0.5 = 147 + 1/2 = 147 & 1/2

<h3>The correct area is 147 & 1/2 feet</h3>

If m proportional to n and m=5 when n=4.what is the valuue of m?when n=18
Dovator [93]

Answer:

m=22.5

Step-by-step explanation:

m is proportional to n means there is some constant k such that:

m=kn

If m=5 when n=4 then we have the following equation to solve for our constant k:

5=k(4)

5=4k

Divide both sides by 4:

5/4 =k

So k=5/4 no matter what (m,n) pair they give you where the equation is m=kn.

m=(5/4)n

What is m when n=18?

m=(5/4)(18)

m=(5/2)(9)

m=45/2

m=22.5
