Answer:

75 minutes

Step-by-step explanation:

Make an equation

4 pies to 15 minutes = 20 pies to x minutes

4 / 15 = 20 / x

Now cross multiply

4x = 15 × 20

And multiply 15 and 20

4x = 300

Then divide both sides by 4

x = 75

So your answer is 75 minutes

Carolyn is building a pen for a dog. The PERIMETER of the pen is 52 ft. The material is sold by the yard. It is 10.99 dollars pe
Mazyrski [523]
     We know that the fence is 52 <em>feet</em> long, but since it's sold in yards, we need to somehow convert feet to yards.
     First, we need to find a little something called a conversion factor. Basically, we need to see what we can do to get from <em>one foot</em> to <em>one yard</em>. 
Well, how many feet are there in a yard? <em><u>3.</u></em><u /><u /> So now we know that <em><u>one foot is 1/3 of a yard.</u>
</em>     
So to convert 52ft to yards, we need to divide by 3. What's 52 divided by 3? 
17.33.
Now we just need to multiply that by 10.99 so that we can find out the cost.
We get 190.45. That's your answer!

It all cost <em>$190.45
</em>
